Even if we could accurately diagnose SIBO, if there is no difference in symptoms between those testing positive and those testing negative, what’s the point? It may not be the number of bacteria growing in our small intestine, but the type, which can be corrected with diet.

A century ago, the age of first menstruation averaged as late as nearly 17. Why is sexual maturity coming so much earlier now?

Donating time and money isn’t just good for the world, it may be good for our health.

Irrigation (also called ear syringing), which involves flushing out ear wax with a low-pressure jet of warm (body temperature) water, works up to 70 to 90 percent of the time.

Where did the idea of therapeutic fasting come from?

Photographs are taken inside the ear canal before and after ear candling to put it to the test.

Self-experimentation with the anti-aging drug rapamycin continues to be strongly discouraged.

See if you know more about basic nutrition than most doctors.

Rapamycin appears to be a universal anti-aging drug, extending the lifespan of all animals tested to date; it’s the only known drug to do so.

Inhibiting mTOR, the “master determinant of lifespan,” is considered the best validated aging regulator.

How effective are flu shots, elderberries, echinacea, and cranberries?

Probiotics can actually interfere with microbiome recovery after antibiotics, rather than facilitate it.

It may be prudent to limit chronic, vigorous exercise to no more than an hour a day and no more than five hours a week, taking at least one or two days off. For runners, the recommended upper limit for longevity benefits is 30 miles a week.

What do hospitals have to say for themselves for feeding people meals that appear to be designed to inspire repeat business?

I was surprised by how much controversy is in the medical literature over whether the apparent longevity benefits of exercise are even real.

The evidence supporting the overall health benefits of physical activity is overwhelming.

One of the few food contaminants found at higher levels in those eating plant-based diets are mycotoxins, fungal toxins in moldy foods, such as oats. Most food crops are contaminated with fungal mycotoxins, but some are worse than others.

The official exercise recommendations are a “trade-off between optimizing health outcomes and minimizing requirements for individuals,” but what does the science say is best?

Five massive new trials have been published recently, randomizing tens of thousands to various formulations of fish oil versus placebo.

Caloric restriction can boost levels of brain-derived neurotrophic factor (BDNF), which is considered to play a critical role in mood disorders.

Blue-green algae, chlorella, and spirulina are all advertised as being beneficial, but they could be harmful because they are often contaminated with algal toxins.

I explain why I no longer consume chlorella.

After drinking two cups of water, the adrenal hormone noradrenaline can surge in your bloodstream, as if you just smoked a few cigarettes or had a few cups of coffee.

Why do I recommend staying away from blue-green Algae?

Currently, there are more than 30 FDA-approved testosterone products for men, but none for women.

If the nitrites in foods like ham and bacon cause lung damage, what about “uncured” meat with “no nitrites added”?

Other than a “space headache,” what might be the downsides of sleeping at a slight head-down tilt to accelerate fat loss?

How might we trick our body into producing this fat-burning exercise hormone without lacing up our gym shoes?

Palmitic acid, a saturated fat concentrated in meat and dairy, can boost the metastatic potential of cancer cells through the fat receptor CD36. Randomized controlled trials show that lowering saturated fat intake can lead to improved breast cancer survival.

When we get dehydrated, the shrinkage of our blood volume can lead to the release of angiotensin, which can lead to weight gain.
