Billion-dollar drugs have been pulled from the market for less carcinogenic contamination than is found in a single serving of grilled chicken.
In 2018, one of the bestselling blood pressure drugs, valsartan—sold as Diovan—was found to be contaminated by the “probably carcinogenic” nitrosamine known as N-nitrosodimethylamine (NDMA). It’s believed that about 20 million people worldwide were prescribed the drug tainted with this contaminant, which has a cancer risk shown to exceed that of many known potent carcinogens, such as asbestos, PCBs, and benzo[a]pyrene.
As I discuss in my video Cancer-Causing NDMA in Medications (Zantac, Metformin) and Meat, the U.S. Food and Drug Administration (FDA) estimated that taking the drug for a few years could cause cancer in as many as 1 in 8,000 people, whereas the European equivalent of the FDA estimated the cancer risk could be as high as 1 in 5,000. It is unlikely, researchers wrote in this 2019 paper, that drugs like valsartan are “a unique case.” And indeed, a few months later, the FDA announced it had found NDMA in ranitidine. Ranitidine, the acid reflux drug sold as Zantac, is one of the most prescribed drugs on the planet, in addition to being sold over the counter.
Then in 2020, some formulations of metformin, a popular diabetes drug sold as Glucophage, were found to be contaminated. The finding of NDMA in common medicines led the FDA to call for the immediate withdrawal of all Zantac from store shelves, yanking the drug from the market because its testing showed NDMA levels could, in some circumstances, exceed the acceptable daily intake limit of 96 nanograms per day. It was so bad that the FDA found levels of this carcinogenic contaminant in Zantac are similar to the exposure levels you would experience if you ate grilled or smoked meats!
Wait, what?
NDMA has not only been found in contaminated drugs. It is a known byproduct of tire plants, pesticide manufacturing, and leather tanning, and it is found in food and beverages, including processed meat and beer. Now that we know NDMA can transfer through the placenta, this may explain the relationship between maternal cured meat consumption during pregnancy and the risk of childhood brain tumors. For example, eating hot dogs while pregnant may increase childhood brain tumor risk by 33%, and sausages by 44%. Bacon consumption may increase childhood brain tumor odds by 60 or 70%. But it’s not just processed meat. Researchers have found it in poultry products as well. A single serving of chicken contains more than 100 nanograms of NDMA, as you can see below and at 3:02 in my video.
Remember how the FDA said the acceptable daily intake limit is 96 nanograms? Just half a chicken breast contains 110 nanograms.
Now, raw poultry doesn’t have any NDMA; it comes from the cooking process. In fact, the dry-heat cooking of meat, like broiling or grilling, even creates airborne NDMA, releasing this very potent carcinogenic compound into the air. So, even if you’re getting a salad at a charcoal grill restaurant, just being indoors where meat is being grilled could be a significant cancer risk.
Nitrosamines are also found in cigarette smoke, and pressure was put on the tobacco industry to try to remove them, arguing “there is simply no logical reason why a removable carcinogen should be allowed to remain in a consumer product….” That’s the same reason Zantac was yanked from store shelves.
Okay, so let’s get this straight. Zantac—which is one of the best-selling drugs in history, bringing in billions of dollars—was pulled from the market because it contained a probable carcinogen that exceeded the acceptable daily limit, but there may be more of the contaminant in a single serving of chicken?! So, my question is: Why aren’t they pulling poultry off the shelves, too?
Noise pollution has become part of everyday life in many cities, yet its impact on sleep and cardiovascular health is often underestimated. In dense urban soundscapes, constant traffic, construction, and nightlife noise can drive sleep disruption, activate the body’s stress response, and contribute to higher blood pressure over time.
Understanding these links helps explain why some city residents feel persistently tired, stressed, and unwell, even when they seem to be “used to” the noise.
Noise Pollution in Urban Soundscapes
Noise pollution refers to unwanted or excessive sound that harms health or quality of life. In urban soundscapes, this usually comes from road and rail traffic, aircraft, construction work, sirens, and crowded entertainment districts.
The problem is not just occasional loud events, but continuous or frequent noise that leaves little time for genuine quiet.
People living near busy roads, flight paths, or nightlife zones may experience elevated noise levels both day and night. Even when they stop consciously noticing the sound, the body continues to register it. Over time, this ongoing exposure can shape sleep patterns, stress responses, and cardiovascular function in subtle but important ways.
How Urban Noise Affects Sleep
During sleep, the brain does not fully disconnect from the environment. The auditory system keeps monitoring for sounds that might signal danger. Noise can trigger micro‑arousals, brief shifts to lighter sleep stages, even if the person does not remember waking up. These small interruptions fragment the sleep cycle.
As a result, people may spend less time in deep and REM sleep, which are essential for physical recovery, memory processing, and emotional regulation. In noisy urban soundscapes, such sleep disruption can occur many times a night.
Over weeks and months, this pattern often leads to non‑restorative sleep, morning fatigue, and difficulty concentrating, even if total time in bed seems adequate.
Repeated nighttime disturbances can also resemble insomnia. Residents may lie awake waiting for the next siren or truck, making it hard to relax. Shortened sleep, irregular bedtimes, and poor sleep quality can gradually erode mood, performance at work or school, and overall resilience.
Noise, Stress Response, and Higher Blood Pressure
From a biological standpoint, significant noise acts as a stressor. The body responds by activating the sympathetic nervous system and releasing hormones such as adrenaline and cortisol. This stress response increases heart rate and blood pressure and prepares the body for action.
In quiet environments, these stress reactions are short‑lived. In noisy cities, however, they may be triggered repeatedly throughout the day and night by horns, engines, construction, or loud voices. Over time, frequent activation can create a state of chronic, low‑grade stress.
Nighttime noise is particularly important. Sleep is meant to be a period when blood pressure and heart rate naturally drop, allowing the cardiovascular system to recover, according to the World Health Organization.
When noise keeps the stress response active, this normal nighttime “dipping” can be blunted. Instead of extended calm, the body experiences a stop‑start pattern of activation, which gradually changes how blood vessels and the heart function.
Higher blood pressure develops through many factors, but noise exposure adds to the load. Repeated surges of stress hormones cause blood vessels to constrict and the heart to work harder.
In chronically noisy urban soundscapes, these reactions can become the new baseline, nudging resting blood pressure upward. Over months and years, this process increases the risk of sustained hypertension and related cardiovascular problems.
Studies of people living near busy roads, railways, and airports consistently show links between long‑term noise exposure, sleep disruption, and higher blood pressure. Some research has captured immediate spikes in blood pressure during specific noise events at night, even when the person appears to remain asleep.
These findings highlight that noise is not just irritating; it has measurable effects on the cardiovascular system.
Broader Health Impacts of Noisy City Living
The health effects of noise extend beyond higher blood pressure. Chronic exposure in urban soundscapes is associated with increased anxiety, irritability, and depressive symptoms. Poor sleep and constant low‑grade stress can make it harder to cope with daily demands, regulate emotions, and maintain social relationships.
Cognitive performance may also be reduced in persistently noisy environments. Concentration, memory, and learning suffer when the brain must constantly screen out background sound.
Children who live or study near major roads or flight paths can face extra challenges focusing and retaining information, which may affect academic progress.
For many city dwellers, these issues overlap: fragmented sleep, daytime tiredness, elevated stress, and gradual increases in blood pressure all influence one another. The combined effect can be a noticeable drop in productivity, well‑being, and quality of life, even if noise is rarely identified as the main cause, as per the Centers for Disease Control and Prevention.
Practical Ways to Reduce Noise Impact
Individuals cannot eliminate all urban noise, but they can limit its impact on sleep and blood pressure. Helpful steps include:
Placing bedrooms on the quieter side of the building whenever possible
Using heavier curtains, better window seals, or double glazing to reduce sound intrusion
Employing constant background sound, such as a fan or white‑noise device, to mask sudden peaks
Wearing comfortable earplugs at night in particularly loud locations
Supporting habits such as regular bedtimes, a calming pre‑sleep routine, and reduced caffeine and screen use in the evening can also improve sleep quality despite ongoing noise exposure.
People who notice persistent sleep disruption, morning headaches, daytime fatigue, or rising blood pressure while living in noisy areas should consider discussing these concerns with a health professional. Tracking sleep and blood pressure over time can help clarify how strongly noise and sleep disruption might be contributing.
Those with existing cardiovascular disease, older adults, shift workers, and residents near major transport routes may be especially vulnerable. For them, reducing noise exposure and improving sleep quality are meaningful parts of managing higher blood pressure and protecting heart health.
Noise, Urban Soundscapes, and Protecting Long‑Term Heart Health
In modern cities, noise is often treated as an inevitable backdrop. Yet chronic exposure to loud urban soundscapes plays a clear role in sleep disruption, activation of the stress response, and higher blood pressure. Recognizing noise as a significant environmental influence on health is an important step toward change.
At the personal level, small adjustments to the home and sleep routine can help shield the body from constant sound. At the community and policy level, measures such as traffic calming, quieter infrastructure, and stricter nighttime standards can reshape urban soundscapes in ways that support restorative sleep and cardiovascular health.
By understanding how noise interacts with sleep, stress, and blood pressure, societies can move toward cities that are not only vibrant and active, but also genuinely healthy places to live.
Frequently Asked Questions
1. Can noise pollution raise blood pressure even if someone feels used to it?
Yes. The body can still react with stress hormones and subtle blood pressure increases to ongoing noise exposure, even when a person no longer consciously notices the sound.
2. Are short bursts of loud noise as harmful as constant background noise?
Short, very loud bursts can cause immediate spikes in heart rate and blood pressure, while constant moderate noise tends to contribute more to long‑term stress and sleep disruption.
3. Does noise at work affect blood pressure the same way as nighttime noise?
Workplace noise can increase stress and temporary blood pressure, but nighttime noise is more strongly linked to long‑term cardiovascular effects because it interferes with restorative sleep.
4. Can listening to music at night offset the impact of city noise on sleep?
Soothing, low‑volume music or soundscapes may help some people relax and mask traffic noise, but if it is too loud or stimulating, it can still disturb sleep quality.
Anal cancer is a type of cancer that forms in the tissues of the anus.
The anus is the end of the large intestine. It is where stool (solid waste) leaves the body. The anus is formed partly from the outer skin layers of the body and partly from the intestine. The anus is connected to the rectum by the anal canal, which is about 1 to 1½ inches long. This area is controlled by two ring-like sphincter muscles, which contract to hold stool in and relax to allow its passage out of the body.
Anal cancer can start in the lining of the anal canal, called the mucosa, or in the perianal skin, the squamous cells outside of the anus that contain hair follicles and sweat glands.
Tumors of the perianal skin that do not involve the anal sphincter are usually treated the same as anal cancers, although local therapy (treatment directed to a limited area of skin) may be used for some.
Squamous cell carcinoma is the most common type of anal cancer. In the United States, squamous cell carcinoma is the most common type of anal cancer. Studies show that human papillomavirus (HPV) infection is the main cause of this type of anal cancer.
Another type of anal cancer, called anal adenocarcinoma, is very rare and is not discussed in this summary.
High blood pressure often develops quietly, damaging blood vessels and increasing the risk of heart attack, stroke, and kidney disease. Many people do not notice symptoms until complications appear, which is why prevention matters early. The good news is that lifestyle choices can make a major difference in reducing risk and improving long-term heart health.
Simple daily habits such as better nutrition, regular movement, healthy sleep, and stress control can help lower blood pressure naturally. Small changes done consistently often lead to measurable results over time. With the right routine, hypertension prevention becomes more achievable and sustainable for people of all ages.
7 Essential Habits to Prevent High Blood Pressure
Preventing high blood pressure often starts with simple daily choices that protect your heart over time. These seven essential habits can help lower your risk, improve circulation, and support long-term heart health naturally.
1. Follow the DASH Diet
The DASH diet is one of the most effective eating plans to prevent high blood pressure by focusing on fruits, vegetables, whole grains, beans, nuts, and low-fat dairy. Limiting sugary drinks, red meat, and processed foods while adding potassium-rich foods like bananas and spinach can support lower blood pressure and better heart health.
2. Get Regular Aerobic Exercise
Walking, cycling, swimming, and jogging can help lower blood pressure naturally when done consistently. Aim for at least 150 minutes of moderate aerobic exercise weekly to improve circulation, reduce stress, and support weight control.
3. Maintain a Healthy Weight
Carrying extra body weight increases strain on the heart and blood vessels, which may raise blood pressure over time. Losing even a small amount of weight through healthy eating and activity can improve readings and support hypertension prevention.
4. Reduce Sodium Intake
Too much sodium can raise blood pressure in many adults, especially when intake is frequent and high. Choosing fresh foods, reading labels, and seasoning meals with herbs or lemon instead of salt can help reduce sodium levels.
5. Manage Stress Daily
Chronic stress may contribute to unhealthy blood pressure patterns and long-term heart strain. Mindfulness, breathing exercises, journaling, or yoga can help lower stress while supporting better sleep and wellness.
6. Improve Sleep Quality
Poor sleep is linked with a higher risk of high blood pressure and cardiovascular problems. Aim for seven to nine hours of sleep nightly and maintain a regular schedule to improve overall health.
7. Limit Alcohol and Avoid Smoking
Too much alcohol may gradually increase blood pressure, while smoking damages blood vessels and strains the heart. Reducing alcohol intake and quitting smoking can quickly improve heart health and lower long-term risk.
Prevent High Blood Pressure: Dietary Patterns and Food Choices
Prevent high blood pressure by focusing on eating patterns rather than one “superfood.” The DASH diet and Mediterranean-style eating plans both emphasize vegetables, fruit, lean proteins, legumes, whole grains, and healthy fats. These approaches may support better blood pressure levels while improving cholesterol and overall heart health.
According to the Centers for Disease Control and Prevention, reducing sodium, choosing healthier foods, and maintaining a healthy weight are key strategies for managing and preventing high blood pressure. Potassium-rich foods such as beans, leafy greens, potatoes, bananas, and yogurt can also support healthier blood pressure balance. Learn more at
Meal timing can also help some people. Regular meals with balanced portions may support blood sugar stability and reduce overeating later in the day. Sustainable habits matter more than extreme restrictions.
Hypertension Prevention: Exercise Protocols and Monitoring Strategies
Hypertension prevention improves when exercise becomes part of a weekly routine. Moderate aerobic movement such as brisk walking for 30 to 45 minutes on most days can strengthen the heart and help lower blood pressure. Resistance training two to three times weekly may add further benefits.
Based on guidance from the American Heart Association, regular physical activity is one of the most effective natural tools for lower blood pressure and heart health. Combining cardio exercise with strength training can improve circulation, body composition, and metabolic wellness. More guidance is available at
Home blood pressure monitoring is also valuable. Use a validated device, measure at consistent times, and track trends rather than single readings. This can help identify patterns and motivate healthier habits.
Heart Health: Sleep, Stress Reduction, and Long-Term Lifestyle Support
Heart health depends on more than food and workouts. Sleep quality, emotional stress, and routine daily behaviors all influence blood pressure. Poor sleep and ongoing tension may keep the body in a heightened stress state that affects vascular function.
Based on research from National Heart, Lung, and Blood Institute, sleep habits, stress management, and healthy routines are important parts of blood pressure control and cardiovascular wellness. Relaxation techniques such as deep breathing, meditation, and consistent sleep schedules may help support healthier readings. Learn more at
Long-term success usually comes from stacking small habits rather than chasing quick fixes. Protecting heart health is often about what you repeat daily.
Essential Heart Health Habits for Lifelong Blood Pressure Control
High blood pressure prevention works best when healthy habits become part of everyday life. Eating better, moving regularly, sleeping well, managing stress, and avoiding tobacco all work together to reduce long-term risk. Even modest changes can create meaningful progress when maintained consistently.
Lower blood pressure goals do not require perfection. What matters most is building routines that fit your lifestyle and can last for years. With patience and consistency, hypertension prevention becomes a realistic path toward stronger heart health and better overall wellbeing.
Frequently Asked Questions
1. Can high blood pressure be prevented naturally?
Yes, many people can reduce risk through lifestyle habits. Healthy eating, exercise, sleep, and stress management all help. Avoiding smoking and excess alcohol also matters. Genetics can still play a role, so regular checkups remain important.
2. What foods help lower blood pressure?
Foods rich in potassium, fiber, and healthy fats may help. Examples include leafy greens, beans, oats, berries, yogurt, nuts, and fish. Lower-sodium choices are also helpful. Balanced eating patterns matter more than single foods.
3. How much exercise helps blood pressure?
A common target is 150 minutes of moderate activity weekly. This can include walking, biking, or swimming. Strength training can add benefits as well. Consistency matters more than intensity for many people.
4. When should I see a doctor about blood pressure?
See a doctor if readings stay elevated or symptoms concern you. Severe headaches, chest pain, or shortness of breath need prompt care. Regular monitoring helps catch issues early. Professional guidance is useful for personalized treatment plans.

This guided walking meditation from Kazumi Igus offers an opportunity to slow down and notice the wonder of the natural world in our urban environments.
City life can often feel frantic, loud, and cut off from natural beauty. It’s not often we slow down and take in all there is to experience. But even in urban areas, if you pay attention, you can hear the call of a bird, notice your favorite color in shop windows, and look up at the vast sky above.
In this guided meditation, we slow our roll and take in the beauty of our surroundings, no matter where we find ourselves.
A Guided Walking Meditation to Notice the Beauty Around Us—Even in the City
Read and practice the guided meditation script below, pausing after each paragraph. Or listen to the audio practice.
Let’s start with taking three deep breaths.
As we begin, I want to bring your attention to how you are moving if you’re walking through the city or trying to get from one place to another. How fast are you moving? How are you walking? What’s your pace? Do you have a destination and a timeframe? Or do you have some space? Wherever you are, slow it down just a little bit. If you can afford to walk really slow and won’t hold up traffic, you’re welcome to. And if you’re not walking and you’re in a wheelchair, you’re welcome to slow down. If you really need to be somewhere, try to relax into this space, whatever it is. Slow and steady, but maybe not too slow depending on where you are.
Bring your attention to how you are walking—your balance. Are you taking a step? Start to notice the small changes, the muscles involved. And whatever you’re thinking, all of it is OK. You’re just noticing where you are in this space right now.
Then, acknowledging that our minds sometimes race and we have a lot of things going on in our lives, just take a deep breath and bring your attention back to each step. Start to settle into a rhythm. Notice every muscle that’s involved with creating this locomotion to propel you forward and shift your weight. Maybe if you’re in a wheelchair, you’re using your arms. How are the hands involved? Are you holding something? Maybe a backpack, bag, or someone’s hand. Focus on really being present with your physical space, your physical body. Take a deep breath. As we move through our urban environment, we start to notice other things outside of ourselves.
The first thing I want you to bring your attention to is the smell around you. Depending on where you are, that can be pleasant or unpleasant. Breathing in, can you identify a particular smell? Maybe you’re getting a lot of smells all at once. Maybe you notice the change in smells as you move past different areas. And as you experience these smells, notice what you’re thinking. Are you creating a story? Are you finding yourself wanting to be near a pleasant smell or maybe pushing away, trying to avoid an unpleasant smell? If that’s the case, that’s all right. All of it is normal. Just experience the smell and label it as pleasant, unpleasant, or neutral. See if you can identify pizza, poop, grass, or whatever it is.
Then take a deep breath and shift your attention to sights. What can you see? Start by focusing on a color that brings you joy. If it’s a bright color you might notice it in wrappers from candy or chips, maybe in ads, signs, storefront windows that have lots of flyers. If it’s something more earthy, like green or brown, you might start to notice it in nature—the trees and plants. Just pick your color and start noticing it on your journey. Even if the color is on a man-made object like clothing, hats, backpacks, signs, and things like that, that’s a part of the urban environment. If it’s flowers, trees, plants, we’re just noticing the natural portions of the urban environment. Both are necessary.
Taking another deep breath, we shift to looking at nature. Starting with animals. And for this, let’s maybe not focus on people and their pets. Let’s look for the animals that exist in this environment without being owned by a person. You might notice lizards depending on where you are in the world, cats that don’t have owners, squirrels, insects.
I’d like to bring your attention to the birds. Birds are what we call an indicator species. They tell you if your environment is healthy. So look up. Look around. Listen. You might even need to stop for a moment. If you can hear birds, start to listen for the variations in their calls, maybe even a different species. If you have mockingbirds, sometimes it’s the same bird making a bunch of different calls. Really stop to listen to it as though they’re telling you something. If the sound of traffic muffles some of the calls, it’s OK. The urban environment is complex. It has both manmade and natural things. If you can see the birds, notice their behaviors, the coloration, and any other details that might pop out at you. And notice your thoughts while seeing or hearing the birds. You might be able to see or hear seagulls if you’re near a coast, rock doves, a.k.a. pigeons, finches, sparrows, chickadees. Notice if you can identify any of these species by site or by call. Take a deep breath, noticing where the birds are. Probably in plants, trees, bushes, or on grass.
Those of us who live in urban environments often have plant blindness and don’t notice the plants. Take a moment to notice leaves and if you can see any patterns in how those plants are growing. Are there any flowers? Maybe you can recognize a specific species. Can you name it? Take a deep breath. Experience being around plants and animals in nature.
And as you continue moving keep noticing your color, new plants, new animals. Notice what you’re thinking and if you’re telling yourself a story or if you’re asking a lot of questions. And if you are, take a deep breath and then focus back on the details of the experience—the shape of the leaves, the color of the feathers. As humans, we cannot survive without the natural parts of the environment. So it’s very important for us to be mindful of how our movement through the world affects the nature around us and how the nature around us can affect our experience. Take another deep breath. If there’s a big tree or a squirrel that’s standing there looking at you, or a plant that’s intriguing, take a moment to stop.
Be grateful for its part of this urban environment. Expressing some gratitude that you are even able to experience it today. Taking a deep breath. Finding your walking rhythm. Slow but steady, or whatever works for you. Continuing to notice your color, plants, the animals. And continuing to take deep breaths.
What did randomized, controlled human trials find about the ways we may—or may not—benefit from eating onions?
Onions are potentially a good source of antioxidants, which, interestingly, are concentrated in the outer layers just beneath the papery peel. White onions, for example, contain more than ten times the antioxidants in the outer layer compared to the inner core. Unfortunately, most people discard the most nutrient-rich outermost layers, “thus losing a valuable part of the antioxidant-rich material.” In general, yellow onions have more antioxidants than white onions. Red onions beat them both, based on three different antioxidant testing methods, as seen at 0:39 in my video Are Onions Beneficial for Testosterone, Osteoporosis, Allergies, and Cancer?
Though red onions are indeed slightly better, yellow and white onions are no slouches, containing considerable levels of antioxidant activity. We know they’re nutritious, but are there any particular clinical benefits to eating onions? There are all sorts of headlines in the medical literature touting miraculous benefits, but what are these claims based on?
For example, there’s a review purporting to have evidence that testosterone levels in males are enhanced by onion, but the researchers were referring to studies like one on the effects of onion juice after testicular torsion in rats. Who cares what happens after a rat’s testicle is rotated 720 degrees counterclockwise? (Except, of course, the rat.) You don’t know what happens in people until you put human testes to the test. Only then was it discovered that onion extract doesn’t appear to affect men’s testosterone.
What about bone health? Evidently, older white women who ate onions at least once a day had an overall bone density that was 5% greater than women who ate onions no more than once a month. Now, 5% might not sound like a lot, but that improvement in bone density could potentially mean decreasing their hip fracture risk by more than 20% if, indeed, it is cause and effect.
Daily administration of onion for four weeks did cause a big bump in bone density. This could lead to a safe, effective, and low-cost approach to osteoporosis in—you guessed it—rats. Another rodent study!
Great strides have been made in treating osteoporosis with drugs, but they have the potential for serious adverse side effects, so scientists have turned their attention to natural remedies. In one study, researchers randomized people to drink onion juice or placebo onion juice for 8 weeks. Improvement was noted for a marker of bone health; however, they didn’t actually follow participants long enough to compare osteoporosis rates.
Do shallots exhibit anti-allergy activity or offer any therapeutic effects for relieving allergic runny noses? Sixteen patients were randomized equally into an antihistamine group or a group that got antihistamines and capsules containing dried shallot powder. It looked like the shallot group did better after four weeks, but there was no statistically significant difference in total symptoms between the two groups. So, another #onionfail.
What about testing the effects of eating fresh yellow onion to try to decrease the toxic effects of a chemotherapy drug called doxorubicin in breast cancer patients? Unfortunately, no significant benefit was found in decreasing damage to the liver or heart. But eating fresh yellow onion was found to help reduce high blood sugar levels and insulin resistance in breast cancer patients during doxorubicin-based chemotherapy. The drug isn’t just toxic to the liver and heart—it may also contribute to insulin resistance.
So, researchers performed a randomized, triple-blind, controlled clinical trial, randomizing patients to eat a whole onion a day or a third of an onion a day for eight weeks. What happened? The higher-dose onion group experienced a significant decrease in blood sugars and insulin resistance compared to the lower-dose group. Levels rose in the lower-dose group but fell in the higher-dose group, as you can see below and at 4:28 in my video.
So, make onions your friend. What’s the worst that can happen—a little onion breath and body odor?

Berberine has become one of the most discussed natural compounds in the world of weight loss supplements. Many people use it for support with blood sugar balance, cholesterol levels, and body weight, especially when metabolic health is a concern.
Interest in berberine weight loss continues to rise because it may work through several pathways tied to insulin sensitivity and energy regulation. While results are usually moderate, berberine may offer useful support when paired with nutrition, movement, and consistent habits.
Many people first hear about berberine benefits because of weight management, but its potential effects go beyond the number on the scale. Berberine is often linked to activation of AMPK, an enzyme involved in cellular energy use, glucose metabolism, and fat oxidation.
This may help improve blood sugar control, particularly for individuals dealing with insulin resistance or early metabolic dysfunction. Better glucose handling can also support appetite balance and lower energy crashes that make healthy eating harder. According to the Mayo Clinic, berberine has shown promise for lowering blood sugar and cholesterol levels, though more long-term research is still needed.
Berberine may also support lipid health by helping reduce LDL cholesterol and triglycerides. Because of this, it is often discussed in relation to metabolic syndrome, where blood sugar, cholesterol, blood pressure, and abdominal weight gain occur together. Some early research also points toward anti-inflammatory effects. Since chronic inflammation can worsen obesity and insulin resistance, this may be another reason berberine remains popular in wellness circles.
Berberine Weight Loss: Mechanisms, Dosage, and Clinical Results
When discussing berberine weight loss, realistic expectations are important. It is not typically associated with rapid transformations, but some people may experience modest reductions in body weight over time. One reason is that berberine may improve insulin sensitivity, making it easier for the body to regulate stored energy and hunger signals. It may also influence gut bacteria involved in digestion and metabolism.
Researchers have also explored whether berberine affects pathways related to satiety hormones and mechanisms similar to GLP-1 agonists. While it is not equivalent to prescription GLP-1 medications, overlapping appetite and glucose benefits are often discussed.
Based on information from WebMD, berberine is commonly used in divided doses ranging from 900 mg to 1,500 mg daily, often taken with meals to improve tolerance. Most users need several weeks before noticeable changes occur. Results are generally stronger when combined with calorie awareness, exercise, sleep improvement, and consistent routines.
Berberine Side Effects: Safety, Interactions, and Contraindications
Understanding berberine side effects is essential before using it regularly. While many people tolerate it well, digestive complaints are the most common issue.These may include nausea, bloating, gas, diarrhea, constipation, or stomach discomfort. Starting with smaller doses and taking berberine with food may reduce these gastrointestinal issues.
According to the National Center for Complementary and Integrative Health (NCCIH), supplements can interact with medications and should be used carefully, especially by people with chronic conditions or those taking prescriptions.Because berberine may lower blood sugar, people using diabetes medications should be cautious. Combining treatments without guidance could increase the risk of hypoglycemia.
It may also affect how the body processes certain drugs, including blood thinners, some cholesterol medications, and immune-related prescriptions. Berberine is generally avoided during pregnancy and breastfeeding unless approved by a healthcare professional. Quality matters too. Choosing third-party tested brands may reduce risks related to contamination or inaccurate labeling.
Berberine Daily Habits: How to Support Better Weight and Metabolic Results
Many people focus only on the supplement itself, but daily habits strongly influence results. If you are using berberine, combining it with smart routines may improve both weight and metabolic outcomes.
Take Berberine With Meals: Taking berberine with food may help reduce gastrointestinal issues such as nausea, bloating, or stomach discomfort. It may also support a steadier blood sugar response after meals.
Prioritize Protein and Fiber: Meals rich in protein, vegetables, legumes, and whole grains can improve fullness and support berberine weight loss goals. This combination may also reduce cravings and overeating.
Stay Consistent With Movement: Walking, strength training, and regular exercise can improve insulin sensitivity. Pairing movement with berberine may enhance metabolic support.
Monitor Blood Sugar Changes: People using berberine for blood sugar control should watch for signs of low blood sugar, especially if taking diabetes medication. Tracking levels may help identify changes early.
Improve Sleep Quality: Poor sleep can increase hunger hormones and worsen insulin resistance. Better sleep habits may strengthen the overall effect of weight management supplements.
Stay Hydrated Daily: Good hydration supports digestion, energy levels, and workout performance. It may also help reduce constipation sometimes linked to supplements.
Review Progress Every Few Weeks: Check body weight, waist size, energy, and eating habits instead of expecting overnight changes. Sustainable progress is usually gradual and more realistic.
Use Medical Guidance if Needed: If you have diabetes, heart disease, or metabolic syndrome, speak with a healthcare professional before long-term use. Personalized guidance can improve both safety and results.
Weight Management Supplements: Where Berberine Fits Best
Among modern weight management supplements, berberine stands out because it focuses on metabolic pathways rather than stimulant effects. That may appeal to people who want support without the jittery feeling linked to some fat burners.
Still, no supplement replaces the fundamentals. Nutrition quality, calorie balance, stress control, movement, and sleep remain the strongest drivers of sustainable progress.
For people with obesity, diabetes, or advanced metabolic syndrome, medical treatment may be more effective than supplements alone. In those cases, professional care can help identify better options. Berberine is best viewed as one supportive tool, not the entire strategy.
Smarter Berberine Results Through Lifestyle and Safety
The strongest outcomes from berberine benefits usually happen when supplement use is paired with consistent daily habits. Better food choices, regular exercise, and healthy sleep patterns create the foundation for lasting metabolic improvement.
For anyone considering berberine weight loss, patience and safety matter more than hype. With realistic expectations and proper guidance, berberine may play a useful role in a balanced long-term plan.
Frequently Asked Questions
1. How much weight can berberine help you lose?
Results vary depending on diet, activity, and health status. Many people experience modest weight loss rather than dramatic changes. Some may lose a few pounds over several weeks. Consistency matters most.
2. How long does berberine take to work?
Some people notice appetite or digestion changes within a few weeks. Metabolic effects often take longer. Many studies examine results over two to three months. Individual responses can differ.
3. Is berberine safer than prescription weight loss drugs?
Not necessarily. Natural supplements can still cause side effects and drug interactions. Prescription medications are tested differently and may be more effective for certain people. Medical guidance helps compare options safely.
4. Can I take berberine every day?
Many users take it daily in divided doses. Long-term use should still be monitored, especially if medications are involved. Digestive tolerance may change over time. Ask a healthcare provider before regular use.
Illnesses caused by respiratory viruses like COVID-19, flu, and RSV can make anyone sick. However, there are a range of risk factors that can increase a person’s chances of getting very sick (severe illness). Generally, people at higher risk of severe illness from respiratory viruses are
Prevention is important
Preventing respiratory illness and its potentially serious complications is especially important for people who are higher risk for getting very sick. Vaccination remains the most important tool for prevention. Talk to your healthcare provider about what’s recommended for you.
Reducing risk
If you, or someone you spend time with, is at higher risk for getting very sick from a respiratory illness, taking actions to help protect yourself and your loved ones is especially important.
Seek health care promptly if you feel sick
If you believe you may have a respiratory virus (if you feel sick or tested positive for one) and you have risk factors for severe illness, seek health care right away for testing and/or treatment. If you have flu or COVID-19, treatment may be an option to make your symptoms less severe and shorten the time you are sick. Treatment needs to be started within a few days of when your symptoms begin.
Older adults
As people get older, their immune systems can change and weaken over time, which can increase the risk for complications from respiratory illnesses. Older adults are also more likely to have underlying health conditions. Most deaths from respiratory viruses occur in people older than 65, with risk increasing sharply with advancing age.

The Eldercare Locator, a national resource funded by the Administration for Community Living, can help older adults find local vaccination clinics, connect with accessible transportation, and provide other assistance in accessing vaccinations.
Young children
Young children, particularly infants, have immune systems that are still developing. In addition, their lungs and airways are smaller, making viruses that affect airways more of a threat. For more specific information by type of respiratory illness, read more:
Special considerations related to prevention and treatment
Masks: Children younger than 2 years should not wear masks because of the risk of suffocation.
COVID-19 treatment: Paxlovid (nirmatrelvir-ritonavir) antiviral treatment for COVID-19 is not authorized for use in children younger than 12 years of age. Remdesivir is a treatment option for children (birth to 18 years of age weighing at least 1.5kg) who are high risk for severe illness. Speak with a healthcare provider about treatment options if your child develops respiratory symptoms.
Flu treatment: There are flu antiviral drugs recommended by CDC for use in children. Oseltamivir (available as a generic version or under the trade name Tamiflu®) is approved for treatment of flu in children 14 days old and older.
People with underlying health conditions
Certain medical conditions like chronic lung disease, heart disease, diabetes, or chronic kidney disease might increase your risk for getting very sick from respiratory viruses. These conditions can weaken the body’s ability to fight off infection or they affect organs also impacted by the respiratory illness. For more specific information by type of respiratory illness, read more:
People with weakened immune systems
People with weakened immune systems (immunocompromise) have lower defenses against infections. Their bodies may have a harder time building lasting protection from past immunization or infection. People can be immunocompromised either because of a medical condition or because they receive immunosuppressive medications or treatments. Examples of medical conditions or treatments that may result in moderate to severe immunocompromise include, but are not limited to, cancer treatment, organ transplant with immunosuppressive therapy, and primary immunodeficiency.

When sick
It can take longer than average for people with weakened immune systems to recover from respiratory viruses. This includes a possible longer duration during which you can spread a respiratory virus to others. If you are immunocompromised, be aware of this when choosing precautions after you return to normal activities following time at home sick.
People with disabilities
Some disabilities can raise a person’s risk of getting very sick from respiratory viruses. For example, some people with disabilities are more likely to have underlying medical conditions, live in congregate settings, or experience factors and conditions stemming from social determinants of health. For more specific information by type of respiratory illness, read more:
The Disability Information and Access Line (DIAL) can help people with disabilities find local vaccination clinics, connect with accessible transportation, and provide other assistance in accessing COVID-19 vaccinations or setting up a vaccination appointment.
Special considerations related to prevention and treatment
Masks: Some people with disabilities may find it difficult to wear a mask. When considering whether to use a mask, people with disabilities or their caregivers can consider the person’s ability to wear a mask correctly (proper mask size and fit), to avoid frequent touching of the mask and face, and to remove the mask without assistance. For people who are deaf or hard of hearing, or people who spend time with someone who is deaf or hard of hearing, clear masks or masks with clear panels are an option.
Working with support providers: People with disabilities who have direct support providers can also help protect themselves from respiratory viruses. For example, ask direct support providers if they are experiencing any symptoms of or have other reasons to believe they might have a respiratory virus. Ask direct service providers to use core and additional prevention strategies, like taking steps for cleaner air as possible to reduce the amount of virus within indoor areas, practicing good hygiene, or wearing a well-fitting mask.
Pregnancy
Changes in the immune system, heart, and lungs during pregnancy can raise the risk of getting very sick from respiratory viruses. In addition, while immunizations received during pregnancy can provide protection to the pregnant woman, they can also help lower the risk for the baby after birth. For more specific information by type of infection, read more:
Treatment during pregnancy
COVID-19antivirals are recommended for persons who are at high risk of severe illness, including adults 65 years and older, people with weakened immune systems, people with certain medical conditions, and pregnant women. It is not recommendedto withhold COVID-19 treatment from pregnant or lactating women because of theoretical safety concerns. For more information on treating COVID-19 in pregnant women, see the IDSA guidelines on initiating remdesivir and nirmatrelvir/ritonavir (Paxlovid).
Flu antivirals are recommended for certain people at high risk for complications from flu, including pregnant women.

A serious car accident in South Florida sets in motion a complex sequence of medical, financial, and legal events that most accident victims have never navigated before and are poorly prepared for. The region’s dense traffic, year-round driving conditions, and high volume of uninsured and underinsured motorists create an environment where serious crashes occur with troubling frequency—and where the gap between what insurance initially offers and what a victim genuinely needs can be enormous. Understanding the medical and legal aftermath of a South Florida car accident from the outset is the best way to protect both your health and your legal rights.
The Medical Priorities in the First Hours and Days
The medical decisions made in the immediate aftermath of a South Florida car accident have consequences that extend well beyond the acute care period. Calling 911 and waiting for emergency medical services ensures that injuries are evaluated and documented by trained professionals whose records carry significant evidentiary weight in subsequent legal proceedings. Accepting transport to the emergency room, even when injuries feel manageable, creates a baseline medical record that establishes both the nature of the injury and its temporal connection to the accident.
Florida’s no-fault PIP insurance requires accident victims to seek medical treatment within 14 days of the accident in order to access PIP benefits for non-emergency care. Missing this 14-day window can limit PIP coverage to emergency services only, reducing the available medical expense coverage from $10,000 to $2,500. This timeline is one of the most consequential and most frequently missed requirements in Florida car accident cases. Every South Florida accident victim should be aware of it and seek evaluation within the required period regardless of whether their injuries seem immediately serious.
Common Injuries and Their Long-Term Medical Implications
The injuries most commonly seen in South Florida car accidents include whiplash and cervical spine injuries, traumatic brain injuries ranging from concussion to severe TBI, lumbar spine injuries requiring surgical intervention, orthopedic fractures, and soft tissue damage that can produce chronic pain syndromes lasting for years. Each of these injury types has specific diagnostic, treatment, and documentation requirements that affect both medical outcomes and legal claims. The Anidjar & Levine Law Firm represents South Florida car accident victims with an understanding of both the medical complexity of these injuries and the legal strategy required to present their full impact effectively in insurance negotiations and in court.
Delayed-onset symptoms are particularly common in car accidents, where the adrenaline and shock of the event can temporarily mask pain and neurological symptoms that become apparent in the hours or days following the crash. Concussion symptoms including headache, cognitive fog, and sleep disturbance may not manifest clearly until a day or two after the accident. Cervical and lumbar spine symptoms frequently intensify in the 24 to 72 hours following the initial injury. Seeking follow-up evaluation when new or worsening symptoms appear—and ensuring that those symptoms are documented in the medical record—is important for both medical care and claim integrity.
Florida’s Legal Framework and How It Applies
South Florida car accident claims are governed by Florida’s no-fault PIP system, the state’s recently modified comparative fault standard with its 51 percent bar, and a two-year statute of limitations that took effect for new claims in 2023. The interplay of these three elements shapes how claims are pursued and what victims can recover. PIP pays for initial medical expenses and partial lost wages regardless of fault. The liability claim against the at-fault driver—available for serious injuries that meet Florida’s threshold—is governed by the comparative fault standard and must be initiated within the two-year limitations period.
The 14-day rule for PIP access, the serious injury threshold for liability claims, and the two-year filing deadline all represent potential traps for South Florida accident victims who are not aware of them. Each one carries the risk of permanently reducing or eliminating the available recovery if not addressed in a timely way. Consulting with a South Florida car accident attorney promptly after an accident is the most reliable way to ensure that none of these requirements is inadvertently missed.
The Path to Fair Compensation in South Florida
Pursuing fair compensation after a South Florida car accident requires a systematic approach to evidence gathering, medical documentation, insurance claim management, and legal advocacy. The strongest claims are those built on a complete and consistent medical record, thorough documentation of the accident scene and liability evidence, and a comprehensive damages presentation that captures both economic and non-economic losses. Gaps in any of these dimensions give insurers the arguments they need to justify inadequate settlement offers.
South Florida’s insurance market—with its combination of required PIP minimums that are frequently inadequate, significant uninsured motorist exposure, and insurers whose claims practices vary considerably—requires legal advocates who know the specific carriers operating in the market and how to negotiate effectively with each of them. For accident victims in Fort Lauderdale, Boca Raton, Miami, and the surrounding communities, working with experienced South Florida personal injury counsel is not just about legal representation—it is about having a guide through one of the most complex and consequential processes they are likely to face.
