The Effects of Nutritional Yeast for Cancer 

How can the beta glucan fiber in brewer’s, baker’s, and nutritional yeast improve wound healing and, potentially, anti-cancer immunity?  My video Benefits of Nutritional Yeast for Cancer opens with an image of an article titled “The Treatment of Inoperable Cancer.” It noted that “200 years ago it was observed that a certain number of malignant growths disappeared after an attack of erysipelas [a type of …

Countering Stress-Induced Immune Suppression with Diet

How might we improve immune function in children and adults under physical or psychological stress?  “Natural immunomodulators”—compounds that might regulate our immune systems naturally—”are getting more and more popular. The popularity, however, often brings over-optimistic claims and mediocre effects.” Such mythical beasts have been sought after for centuries. The current market is full of all sorts of supplements “promising the golden fleece”—inexpensive and without side effects, yet …

Nutritional Yeast to Help Prevent Common Childhood Infections

The amount of beta-glucan fiber in just a dusting of nutritional yeast a day is put to the test in a randomized, double-blind, placebo-controlled trial for the prevention of common childhood illnesses. In 1989, the late Charles Janeway gave a presentation that was to revolutionize our understanding of the immune system. He proposed that we …

Dietary Cure for Hidradenitis Suppurativa

What is the role of dairy- and yeast-exclusion diets on arresting and reversing an inflammatory autoimmune disease? A landmark study suggested that exposure to dietary yeast, like baker’s yeast, brewer’s yeast, and nutritional yeast, may worsen the course of Crohn’s disease, an autoimmune inflammatory bowel disease.

Is Nutritional Yeast Healthy for Everyone?

Those with certain autoimmune diseases such as Crohn’s disease should probably not eat nutritional yeast.

Is Candida Syndrome Real?

Does the presence of Candida in stool correlate with “Candida-hypersensitivity” symptoms, such as headaches and tiredness? And what happens when people are placed on a high-sugar diet?

Does Nutritional Yeast Trigger Crohn’s Disease?

Is the exaggerated reaction of many Crohn’s disease patients to baker’s, brewer’s, and nutritional yeast just a consequence of their inflamed leaky gut, or might the yeast be a contributing cause? “Baker’s Yeast in Crohn’s Disease—Can It Kill You?” is the inflammatory title (no pun intended) of a 1999 journal article. Crohn’s disease is an …

The Effects of Too Much Arsenic in the Diet

Even at low-level exposure, arsenic is not just a class I carcinogen, but may also impair our immune function and increase our risk of cardiovascular disease and diabetes. When people hear about arsenic, they think of it as an acute poison, and, indeed, a tiny amount—a hundred milligrams, about one-tenth the weight of a paperclip—could …

Updating Our Microbiome Software and Hardware

Good bacteria, those living in symbiosis with us, are nourished by fruits, vegetables, grains, and beans, whereas bad bacteria, those in dysbiosis with us and possibly contributing to disease, are fed by meat, junk food and fast food, seafood, dairy, and eggs, as you can see at 0:12 in my video Microbiome: We Are What …

What Exercise Authorities Don’t Tell You About Optimal Duration

Physical fitness authorities seem to have fallen into the same trap as the nutrition authorities, recommending what they think may be achievable, rather than simply informing us of what the science says and letting us make up our own minds. Researchers who accept grants from The Coca-Cola Company may call physical inactivity “the biggest public …
