There is little guarantee that a dietary supplement will actually contain what is advertised on the packaging and not have undeclared contaminants. In one of my videos a few years ago, I talked about how press releases on the latest science coming out of even top medical centers were filled with overstatements and omissions. Medical

What food can eradicate H. pylori in the majority of patients? The salting and pickling of fish produce a novel DNA-mutating chemical called CMBA, which is formed from a reaction of salt, nitrite preservatives, and methionine, an amino acid found concentrated in animal proteins. The nitrites can also interact with other protein components to form

The origins of yoga go back thousands of years, and the practice of yoga for health has become popular worldwide. A 2016 survey estimated that 36 million Americans may be involved in yoga to varying degrees, for example. With so many practitioners, what do we really know about yoga?   What Are the Benefits of

What explains the Achilles’ heel in certain Asian diets? For decades, Japan has had the longest life expectancy in the world, while spending just a fraction on healthcare compared to other high-income countries. This longevity has been attributed in part to Japanese dietary patterns, which are thought to have contributed to their comparatively low rates

Coffee can improve Parkinson’s symptoms within three weeks compared to placebo, but do the benefits last? When James Parkinson described the classic symptoms of Parkinson’s disease, “he could hardly foresee the evolution of our understanding over the next two hundred years”—like the role of nutrition. High dietary intakes of animal fat, mercury, iron, and dairy

Our gut flora is determined by what we eat, for good or for ill. When we eat meat (including seafood), dairy, or eggs, our gut flora can take certain components in them (carnitine and choline) and produce something that ends up as a toxic compound called TMAO, which may set us up for a heart

Why don’t more big payors in health care embrace plant-based eating? Many of the diseases “that cause a constant drain on health care budgets can be prevented by nutrition;” so, why aren’t the big payors getting involved? Even a 1% decline in excess body fat could alone save tens of billions in medical costs. You’d

The hormonal benefits of fenugreek extend beyond the muscle-bulking testosterone boost. In my video about the benefits of fenugreek seeds, I profiled a study in which young men were randomized to a sugar pill or fenugreek capsules for eight weeks, and they got a significant improvement in upper body strength, lower body strength, body composition,

If you put together all the new chemotherapy drugs approved over a dozen years, the average overall survival benefit is only 2.1 months. Though we often hear new cancer drugs described as “game changers” or “breakthroughs,” most afford much more modest benefits. In my last blog, I quoted an editorial in the Journal of the

Most chemotherapy drugs are approved by the U.S. Food and Drug Administration (FDA) without evidence that they benefit survival or quality of life. By 2030, the number of new cancer cases in the United States is expected to skyrocket by 45%, from 1.6 million to 2.3 million every year. Are we really winning the war
