If you’ve heard of billionaire Bryan Johnson, you’ve likely encountered the phrase “bio age testing.” Johnson, the subject of the Netflix documentary Don’t Die, says he’s on a quest to achieve the lowest possible “biological age” (also known as bio age). He reportedly spends millions each year on anti-aging treatments—dozens of daily supplements, weekly acid […]

Big Food uses our hard-wired drive for dietary diversity against us. How did we evolve to solve the daunting task of selecting a diet that supplies all the essential nutrients? Dietary diversity. By eating a variety of foods, we increase our chances of hitting all the bases. If we only ate for pleasure, we might

I debunk the myth of protein as the most satiating macronutrient. The importance of satiety is underscored by a rare genetic condition known as Prader-Willi syndrome. Children with the disorder are born with impaired signaling between their digestive system and their brain, so they don’t know when they’re full. “Because no sensation of satiety tells

I dive into one of the most fascinating series of studies I’ve ever come across. Anyone can lose weight by eating less food. Anyone can be starved thin.

Microwaving is probably the most efficient way to reduce agaritine levels in fresh mushrooms. There is a toxin in plain white button mushrooms called agaritine, which may be carcinogenic. Plain white button mushrooms grow to be cremini (brown) mushrooms, and cremini mushrooms grow to be portobello mushrooms. They’re all the very same mushroom, similar to

“Clearly, in spite of the widely held ‘belief’ in the health benefits of M. oleifera [moringa], the interest of the international biomedical community in the medicinal potential of this plant has been rather tepid.” In fact, it has been “spectacularly hesitant in exploring its nutritional and medicinal potential. This lukewarm attitude is curious, as other

Does the so-called miracle tree live up to the hype? Moringa (Moringa oleifera) is a plant commonly known as the “miracle” tree due to its purported healing powers across a spectrum of diseases. If “miracle” isn’t hyperbolic enough for you, “on the Internet,” it’s also known as “God’s Gift to Man.” Is moringa a miracle

Emulsifiers are the most widely used food additives. What are they doing to our gut microbiome? When grocery shopping these days, unless you’re sticking to the produce aisle, “it is nearly impossible to avoid processed foods, particularly in the consumption of a typical Western diet,” which is characterized by insufficient plant foods, too much meat,
