Can Vegan Fecal Transplants Lower TMAO Levels?

If the microbiome of those eating plant-based diets protects against the toxic effects of TMAO, what about swapping gut flora?

“Almost 2,500 years ago, Hippocrates stated that ‘All disease begins in the gut.’” When we feed our gut bacteria right with whole plant foods, they feed us right back with beneficial compounds like butyrate, which our gut bugs make from fiber. On the other hand, if we feed them wrong, they can produce detrimental compounds like TMAO, which they make from cheese, eggs, seafood, and other meat.

We used to think that TMAO only contributed to cardiovascular diseases, like heart disease and stroke, but, more recently, it has been linked to psoriatic arthritis, associated with polycystic ovary syndrome, and everything in between. I’m most concerned about our leading killers, though. Of the top ten causes of death in the United States, we’ve known about its association with increased risk of heart disease and stroke, killers number one and five, but recently, an association has also been found between blood levels of TMAO and the risks of various cancers, which are our killer number two. The link between TMAO and cancer could be attributed to the inflammation caused by TMAO, but it could also be oxidative stress (free radicals), DNA damage, or a disruption in protein folding.

What about our fourth leading killer, chronic obstructive pulmonary disease (COPD), like emphysema? TMAO is associated with premature death in patients with exacerbated COPD, though it’s suspected that it’s due to them dying from more cardiovascular disease.

The link to stroke is a no-brainer—no pun intended. It is due to the higher blood pressure associated with higher TMAO levels, as well as the greater likelihood of clots forming in those with atrial fibrillation. Those with higher TMAO levels also appear to have worse strokes and four times the odds of death.

Killer number six is Alzheimer’s disease. Can TMAO even get up into our brains? Yes, TMAO is present in human cerebrospinal fluid, which bathes the brain, and TMAO levels are higher in those with mild cognitive dysfunction and those with Alzheimer’s disease dementia. “In the brain, TMAO has been shown to induce neuronal senescence [meaning, deterioration with age], increase oxidative stress, impair mitochondrial function, and inhibit mTOR signaling, all of which contribute to brain aging and cognitive impairment.”

Killer number seven is diabetes, and people with higher TMAO levels are about 50% more likely to have diabetes. Killer number eight is pneumonia, and TMAO predicts fatal outcomes in pneumonia patients even without evident heart disease. Kidney disease is killer number nine, and TMAO is strongly related to kidney function and predicts fatal outcomes there as well. Over a period of five years, more than half of chronic kidney disease patients who started out with average or higher TMAO levels were dead, whereas among those in the lowest third of levels, nearly 90% remained alive.

How can we lower the TMAO levels in our blood? Because TMAO originates from dietary sources, we could limit our intake of choline- and carnitine-rich foods. They’re so widespread in foods,” though we’re talking about meat, eggs, and dairy. “Therefore, restriction of foods rich in TMA-containing nutrients may not be practical.” Can we just get a vegan fecal transplant? “Vegan donors provided the investigators with a fresh morning fecal sample…”

If you remember, if you give a vegan a steak, despite all that carnitine, they make almost no TMAO compared to a meat-eater, presumably because the vegan hasn’t been fostering steak-eating bugs in their gut. See below and at 3:40 in my video Can Vegan Fecal Transplants Lower TMAO Levels?.

Remarkably, even if you give plant-based eaters the equivalent of a 20-ounce steak every day for two months, only about half start ramping up production of TMAO, showing just how far their gut flora has to change. The capacity of veggie feces to churn out TMAO is almost nonexistent. Instead of eating healthier, what about getting some vegan poop?

In a double-blind, randomized, controlled trial, research subjects either got vegan poop or their own poop back through a hose snaked down their nose, and it didn’t work.

First of all, the vegans recruited for the study started out making TMAO themselves, in contrast to the other study, where they didn’t make any at all. This may be because the earlier study required the vegans to have been vegan for at least a year, and this study didn’t. So, there wasn’t much of a change in TMAO running through their bodies two weeks after getting the vegan poop, but the vegan poop they got seemed to start out with some capacity to produce TMAO in the first place.

So, the failure to improve after the vegan fecal transplant “could be related to limited baseline microbiome differences and continuation of an omnivorous diet” after the vegan-donor transplant. What’s the point of trying to reset your microbiome if you’re just going to eat meat? Well, the researchers didn’t want to switch people to a plant-based diet since they knew that alone can change our microbiome, and they didn’t want to introduce any extra factors. The bottom line is that it seems there may not be any shortcuts. We may just have to eat a healthier diet.

Ideal vs. Normal Cholesterol Levels

Having a “normal” cholesterol level in a society where it’s normal to die from a heart attack isn’t necessarily a good thing.

“Consistent evidence” from a variety of sources “unequivocally establishes” that so-called bad LDL cholesterol causes atherosclerotic cardiovascular disease—strokes and heart attacks, our leading cause of death. This evidence base includes hundreds of studies involving millions of people. “Cholesterol is the cause of atherosclerosis,” the hardening of the arteries, and “the message is loud and clear.” “It’s the Cholesterol, Stupid!” noted the editor of the American Journal of Cardiology, William Clifford Roberts, whose CV is more than 100 pages long as he has published about 1,700 articles in peer-reviewed medical literature. Yes, there are at least ten traditional risk factors for atherosclerosis, as seen below and at 1:11 in my video How Low Should You Go for Ideal LDL Cholesterol?, but, as Dr. Roberts noted, only one is required for the progression of the disease: elevated cholesterol.

Your doctor may have just told you that your cholesterol is normal, so you’re relieved. Thank goodness! But, having a “normal” cholesterol level in a society where it’s normal to have a fatal heart attack isn’t necessarily good. With heart disease, the number one killer of men and women, we definitely don’t want to have normal cholesterol levels; we want to have optimal levels—and not optimal by current laboratory standards, but optimal for human health.

Normal LDL cholesterol levels are associated with the hidden buildup of atherosclerotic plaques in our arteries, even in those who have so-called “optimal risk factors by current standards”: blood pressure under 120/80, normal blood sugars, and total cholesterol under 200 mg/dL. If you went to your doctor with those kinds of numbers, you’d likely get a gold star and a lollipop. But, if your doctor used ultrasound and CT scans to actually peek inside your body, atherosclerotic plaques would be detected in about 38% of individuals with those kinds of “optimal” numbers.

Maybe we should define an LDL cholesterol level as optimal only when it no longer causes disease. What a concept! When more than a thousand men and women in their 40s were scanned, having an LDL level under 130 mg/dL left them with atherosclerosis throughout their body, and that’s a cholesterol level at which most lab tests would consider normal.

In fact, atherosclerotic plaques were not found with LDL levels down around 50 or 60, which just so happens to be the levels most people had “before the introduction of western lifestyles.” Indeed, before we started eating a typical American diet, “the majority of the adult population of the world had LDLs of around 50 mg per deciliter (mg/dL)”—so that’s the true normal. “Present average values…should not be regarded as ‘normal.’” We don’t want to have a normal cholesterol based on a sick society; we want a cholesterol that is normal for the human species, which may be down around 30 to 70 mg/dL or 0.8 to 1.8 mmol/L.

“Although an LDL level of 50 to 70 mg/dl seems excessively low by modern American standards, it is precisely the normal range for individuals living the lifestyle and eating the diet for which we are genetically adapted.” Over millions of years, “through the evolution of the ancestors of man,” we’ve consumed a diet centered around whole plant foods. No wonder we have a killer epidemic of atherosclerosis, given the LDL level “we were ‘genetically designed for’ is less than half of what is presently considered ‘normal.’”

In medicine, “there is an inappropriate tendency to accept small changes in reversible risk factors,” but “the goal is not to decrease risk but to prevent atherosclerotic plaques!” So, how low should you go? “In light of the latest evidence from trials exploring the beneﬁts and risks of profound LDLc lowering, the answer to the question ‘How low do you go?’ is, arguably, a straightforward ‘As low as you can!’” “‘Lower’ may indeed be better,” but if you’re going to do it with drugs, then you have to balance that with the risk of the drug’s side effects.

Why don’t we just drug everyone with statins, by putting them in the water supply, for instance? Although it would be great if everyone’s cholesterol were lower, there are the countervailing risks of the drugs. So, doctors aim to use statin drugs at the highest dose possible, achieving the largest LDL cholesterol reduction possible without increasing risk of the muscle damage the drugs may cause. But when you’re using lifestyle changes to bring down your cholesterol, all you get are the benefits.

Can we get our LDL low enough with diet alone? Ask some of the country’s top cholesterol experts what they shoot for, “and the odds are good that many will say 70 or so.” So, yes, we should try to avoid the saturated fats and trans fats found in junk foods and meat, and the dietary cholesterol found mostly in eggs, but “it is unlikely anyone can achieve an LDL cholesterol level of 70 mg/dL with a low-fat, low-cholesterol diet alone.” Really? Many doctors have this mistaken impression. An LDL of 70 isn’t only possible on a healthy enough diet, but it may be normal. Those eating strictly plant-based diets can average an LDL that low, as you can see here and at 5:28 in my video.

No wonder plant-based diets are the only dietary patterns ever proven to reverse coronary heart disease in a majority of patients. And their side effects? You get to feel better, too! Several randomized clinical trials have demonstrated that more plant-based dietary patterns signiﬁcantly improve psychological well-being and quality of life, with improvements in depression, anxiety, emotional well-being, physical well-being, and general health.

Boosting BDNF Levels in Our Brain to Treat Depression

We can raise BDNF levels in our brain by fasting and exercising, as well as by eating and avoiding certain foods.

There is accumulating evidence that brain-derived neurotrophic factor (BDNF) may be playing a role in human depression. BDNF controls the growth of new nerve cells. “So, low levels of this peptide could lead to an atrophy of specific brain areas such as the amygdala and the hippocampus, as it has been observed among depressed patients.” That may be one of the reasons that exercise is so good for our brains. Start an hour-a-day exercise regimen, and, within three months, there can be a quadrupling of BDNF release from our brain, as seen below and at 0:35 in my video How to Boost Brain BDNF Levels for Depression Treatment.

This makes sense. Any time we were desperate to catch prey (or desperate not to become prey ourselves), we needed to be cognitively sharp. So, when we’re fasting, exercising, or in a negative calorie balance, our brain starts churning out BDNF to make sure we’re firing on all cylinders. Of course, Big Pharma is eager to create drugs to mimic this effect, but is there any way to boost BDNF naturally? Yes, I just said it: fasting and exercising. Is there anything we can add to our diet to boost BDNF?

Higher intakes of dietary flavonoids appear to be protectively associated with symptoms of depression. The Harvard Nurses’ Health Study followed tens of thousands of women for years and found that those who were consuming the most flavonoids appeared to reduce their risk of becoming depressed. Flavonoids occur naturally in plants, so there’s a substantial amount in a variety of healthy foods. But how do we know the benefits are from the flavonoids and not just from eating more healthfully in general? We put it to the test.

Some fruits and vegetables have more flavonoids than others. As shown below and at 1:51 in my video, apples have more than apricots, plums more than peaches, red cabbage more than white, and kale more than cucumbers. Researchers randomized people into one of three groups: more high-flavonoid fruits and vegetables, more low-flavonoid fruits and vegetables, or no extra fruits and vegetables at all. After 18 weeks, only the high-flavonoid group got a significant boost in BDNF levels, which corresponded with an improvement in cognitive performance. The BDNF boost may help explain why each additional daily serving of fruits or vegetables is associated with a 3 percent decrease in the risk of depression.

What’s more, as seen here and at 2:27 in my video, a teaspoon a day of the spice turmeric may boost BNDF levels by more than 50 percent within a month. This is consistent with the other randomized controlled trials that have so far been done.

Nuts may help, too. In the PREDIMED study, where people were randomized to receive weekly batches of nuts or extra-virgin olive oil, the nut group lowered their risk of having low BDNF levels by 78 percent, as shown below and at 2:46.

And BDNF is not implicated only in depression, but schizophrenia. When individuals with schizophrenia underwent a 12-week exercise program, they got a significant boost in their BDNF levels, which led the researchers to “suggest that exercise-induced modulation of BDNF may play an important role in developing non-pharmacological treatment for chronic schizophrenic patients.”

What about schizophrenia symptoms? Thirty individuals with schizophrenia were randomized to ramp up to 40 minutes of aerobic exercise three times a week or not, and there did appear to be an improvement in psychiatric symptoms, such as hallucinations, as well as an increase in their quality of life, with exercise. In fact, researchers could actually visualize what happened in their brains. Loss of brain volume in a certain region appears to be a feature of schizophrenia, but 30 minutes of exercise, three times a week, resulted in an increase of up to 20 percent in the size of that region within three months, as seen here and at 3:46 in my video.

Caloric restriction may also increase BDNF levels in people with schizophrenia. So, researchers didn’t just have study participants eat less, but more healthfully, too—less saturated fat and sugar, and more fruits and veggies. The study was like the Soviet fasting trials for schizophrenia that reported truly unbelievable results, supposedly restoring people to function, and described fasting as “an unparalleled achievement in the treatment of schizophrenia”—but part of the problem is that the diagnostic system the Soviets used is completely different than ours, making any results hard to interpret. There was a subgroup that seemed to correspond to the Western definition, but they still reported 40 to 60 percent improvement rates from fasting, but fasting wasn’t all they did. After the participants fasted for up to a month, they were put on a meat- and egg-free diet. So, when the researchers reported these remarkable effects even years later, they were for those individuals who stuck with the meat- and egg-free diet. Evidently, the closer the diet was followed, the better the effect, and those who broke the diet relapsed. The researchers noted: “Not all patients can remain vegetarian, but they must not take meat for at least six months, and then in very small portions.” We know from randomized controlled trials that simply eschewing meat and eggs can improve mental states within just two weeks, so it’s hard to know what role fasting itself played in the reported improvements.

A single high-fat meal can drop BDNF levels within hours of consumption, and we can prove it’s the fat itself by seeing the same result after injecting fat straight into our veins. Perhaps that helps explain why increased consumption of saturated fats in a high-fat diet may contribute to brain dysfunction—that is, neurodegenerative diseases, long-term memory loss, and cognitive impairment. It may also help explain why the standard American diet has been linked to a higher risk of depression, as dietary factors modulate the levels of brain-derived neurotrophic factor.

Essential Tools For Monitoring Oxygen Levels And Heart Rate

Pulse oximeters are small, non-invasive devices used to measure the oxygen saturation level (SpO2) in the blood. It utilizes light beams to assess how much oxygen is being carried by the hemoglobin in red blood cells by attaching the device to a fingertip, earlobe, or other thin-skinned areas. This measurement helps gauge how efficiently oxygen is being delivered throughout the body, providing an essential metric for respiratory and cardiovascular health.

The technology behind pulse oximeters is relatively straightforward. The device emits light through the skin and measures how much of it is absorbed by the blood. Oxygenated blood absorbs light differently than deoxygenated blood, allowing the oximeter to calculate the percentage of oxygen saturation. Most healthy individuals will have an oxygen saturation of 95% to 100%. If levels fall below this range, it could indicate a respiratory or circulatory issue that needs attention.

Uses of Pulse Oximeters

Pulse oximeters are essential tools in various medical fields. They are commonly used in hospitals and clinical settings, especially in situations involving respiratory conditions, anesthesia, or during surgeries. However, they have also become important for home use, particularly for individuals managing chronic conditions like COPD (chronic obstructive pulmonary disease), asthma, or COVID-19, which can affect lung function.

For athletes, particularly those engaged in high-altitude sports, a pulse oximeter can monitor how their body adapts to reduced oxygen availability in the environment. In sleep medicine, pulse oximeters are sometimes used to monitor oxygen levels in individuals with suspected sleep apnea, a condition that disrupts breathing during sleep.

Furthermore, with the growing emphasis on personal health monitoring, many fitness enthusiasts and general users have started to incorporate pulse oximeters into their wellness routines. Having immediate access to oxygen saturation levels provides valuable insights into how well their body is functioning, particularly during physical activity.

Who Should Use Pulse Oximeters?

Pulse oximeters are beneficial for a wide range of individuals. People with chronic lung or heart conditions can use pulse oximeters to track their oxygen saturation regularly and ensure that their body is receiving enough oxygen. It’s particularly useful for individuals diagnosed with conditions such as:

Chronic Obstructive Pulmonary Disease (COPD): Monitoring blood oxygen levels can help prevent dangerous drops in oxygen, which is critical in managing this condition.

Asthma: Asthma patients can benefit from real-time oxygen measurements, especially during asthma attacks when breathing is restricted.

Heart Failure: Individuals with heart failure can use pulse oximeters to check if their heart is pumping enough oxygenated blood to meet their body’s needs.

COVID-19: During the pandemic, pulse oximeters gained widespread usage for monitoring blood oxygen levels in COVID-19 patients, as low oxygen saturation can be an early warning sign of deteriorating respiratory function.

Additionally, healthcare professionals recommend pulse oximeters for individuals undergoing oxygen therapy, those recovering from surgeries involving anesthesia, and people with conditions like pneumonia or sleep apnea. Even healthy individuals, such as athletes or travelers going to high-altitude destinations, can benefit from using pulse oximeters.

How to Use a Pulse Oximeter

Using a pulse oximeter is simple and quick. The device is clipped onto a finger, toe, or earlobe, where it shines a light through the skin to measure the amount of oxygen in the blood. Here’s a step-by-step guide on how to use one:

Prepare the Device: Ensure the pulse oximeter is charged or has functioning batteries. Turn it on before attaching it to your finger or earlobe.

Placement: For most models, placing the pulse oximeter on the index or middle finger is ideal. Make sure the finger is clean and dry, as dirt or moisture can affect the accuracy of the reading.

Wait for Results: The device will display a percentage representing the oxygen saturation (SpO2) level. A typical reading should be between 95% and 100% in healthy individuals.

Monitor Pulse Rate: Alongside oxygen levels, the pulse oximeter will also show your pulse rate. Monitoring both metrics together can give a comprehensive view of your cardiovascular and respiratory health.

Interpret Results: Readings below 90% should prompt immediate medical attention. However, in chronic conditions like COPD, healthcare providers may advise different thresholds based on individual health needs.

Now that we’ve established what pulse oximeters are, their uses, and how to use them, let’s explore the 25 Best Pulse Oximeters available today.

FDA Wants To Further Reduce Salt Levels In Packaged, Processed Food

The U.S. Food and Drug Administration has announced a milestone in its voluntary sodium reduction program by completing the Phase I target and issuing draft guidance for Phase II. In this next phase, the FDA plans to further reduce sodium levels in packaged and processed food by 20%, to bring the average intake to about 2,750 milligrams per day.

According to the U.S. Dietary Guidelines, a person should not consume more than 2,300 milligrams of sodium per day, which is about one teaspoon of salt. The FDA launched its sodium reduction program in 2021, setting a 2.5-year target. The goal for Phase I was to lower the average daily sodium intake from 3,400 milligrams to 3,000 milligrams.

High sodium intake is linked to health issues such as increased blood pressure, a major risk factor for heart disease and stroke. Studies have shown that reducing sodium intake could prevent hundreds of thousands of premature deaths and illnesses. However, to effectively lower sodium consumption, changes need to be made in the food supply itself, as more than 70 percent of sodium comes from processed and prepared foods.

“Reducing sodium in the food supply has the potential to be one of the most important public health initiatives in a generation. The early successes we’re seeing with sodium level reduction in certain foods is encouraging and indicative of the impact we believe our overall nutrition approach can have on the wellbeing of society,” FDA Deputy Commissioner for Human Foods Jim Jones said in a news release.

Phase II will continue to target sodium levels in commercially processed, packaged, and prepared foods in the marketplace.

“In addition to our sodium reduction efforts, the FDA is also actively working on a forthcoming final rule updating the definition of the claim ‘healthy,’ a proposed rule for front-of-package nutrition labeling and exploring ways to reduce added sugars consumption. The FDA’s sodium reduction and other nutrition initiatives are central to a broader, whole-of-government approach to help reduce the burden of diet-related chronic diseases and advance health equity,” Jones added.

The American Heart Association (AHA) advises limiting sodium intake to no more than 2,300 milligrams per day, with an ideal limit of 1,500 milligrams for those with high blood pressure. They suggest that reducing daily sodium intake by 1,000 milligrams can significantly improve blood pressure and heart health.
