Meta-analyses of studies involving more than ten million participants confirm that greater egg consumption confers a higher risk of premature death from all causes.

From a rarity to an epidemic disease, diverticulosis is a disease of fiber deficiency.

The overall cost-benefit ratio for mycotoxins depends on which food is contaminated. Is “toxic mold syndrome” real? And what do we do about toxic mold contamination of food?

The best apple, bean, berry, lentil, and nut are the ones you'll eat the most of; but if you don't have a strong preference, which has the highest antioxidant power?

What does the "milk pus test" tell us about the U.S. milk supply?

Let's discuss weight loss, cholesterol, and PCOS treatment with diet. What can a daily eighth of a teaspoon of onion powder do for body fat, and what can raw red onion do for cholesterol?

Is there an advantage to eating a raw plant-based diet over a diet of raw and cooked whole plant foods?

One reason kids may not be eating more healthfully is that their parents vastly overestimate the quality of their child's diet.

I discuss a public health case for modernizing the definition of protein quality.

What role do vegetarian diets and organic foods play in the prevention or promotion of a birth defect called hypospadias?

A healthy heart doesn't beat like a metronome.

How can we conserve NAD+ by preventing overactivation of the enzymes PARP-1 and CD38, which guzzle NAD+?

A randomized controlled trial investigates diet and psychological well-being.

You can naturally get your body to make more NAD+ by boosting the NAD+ synthesizing enzyme NAMPT.

Particular caution should be used for NAD+-boosting supplements by those with cancer, a personal or strong family history of cancer and perhaps also by those with inflammatory disorders and certain active infections.

What are the pros, cons, and efficacy of dihydronicotinamide riboside (reduced NR), perhaps the most potent NAD+ precursor, as well as reduced NMN, taking NAD+ directly, or making it from scratch from tryptophan?

NR may just be a waste of money, safe but ineffective. NMN seems similarly useless in humans, but it may not even be safe.

The suppression of NAD+ synthesis by NR in humans may explain the disparate rodent results.
