Fat Burning via Flavonoids

Flavonoid phytonutrients (found concentrated in citrus, berries, red onions, beans, green tea, grapes, and cocoa) may boost metabolism enough to significantly slim one’s waistline.



Fat Burning Via Arginine

The arginine content of nuts may explain their metabolism-boosting effects—though, in a list of the top food sources of arginine, nuts don’t even make the top ten.



Testing the Fat-Burning Theory

Finally, there’s a solution to the mystery of why nuts don’t seem to make people gain weight. It appears to be a combination of factors—including a boost to our metabolism, which results in us burning more of our own fat stores.



Creatine Brain Fuel Supplementation

Vegetarians appear to get more of a cognitive boost than meat-eaters from creatine supplementation.



When Meat Can Be a Lifesaver

There are rare birth defects in which the inability to produce certain compounds requires an exogenous source. Presented here is a case report of a boy with a mutation in his carnitine transport system.



Out of the Lab Onto the Track

Randomized, double-blind, placebo-controlled, crossover studies convinced the scientific establishment that nitrate-rich vegetables (such as beets) could noticeably improve athletic performance.



Priming the Proton Pump

To understand how beets could reduce the oxygen cost of exercise while improving athletic performance, one must review the biochemistry of energy production (ATP synthase), and the body’s conversion of nitrates to nitrites into nitric oxide.



Doping with Beet Juice

Beets found to significantly improve athletic performance while reducing oxygen needs—upsetting a fundamental tenet of sports physiology.
