The lifespan extension associated with dietary restriction may be due less to a reduction in calories, and more to a reduction in animal protein (particularly the amino acid leucine, which may accelerate aging via the enzyme TOR).
A bacteria discovered on Easter Island may hold the key to the proverbial fountain of youth by producing rapamycin, which inhibits the engine-of-aging enzyme TOR.
Athletes who overtrain may put excessive stress on their bodies, and become more susceptible to respiratory infections. But, the fiber found in nutritional and brewer’s yeast may prevent this immune decline in marathon runners.
Natural monoamine oxidase enzyme inhibitors in fruits and vegetables may help explain the improvement in mood associated with switching to a plant-based diet.
Dr. Greger has scoured the world’s scholarly literature on clinical nutrition, and developed this brand-new live presentation on the latest in cutting-edge research on how a healthy diet can affect some of our most common medical conditions.
About half of America’s trans fat intake now comes from animal products.
Plant-based diets appear to offer relief from a variety of menstrual symptoms, including cramping, bloating, and breast pain (cyclical mastalgia).
The spice nutmeg may have a relatively narrow margin of safety.
A head-to-head test of the spice saffron versus Prozac for the treatment of clinical depression.
Even the scent of the spice saffron may reduce stress hormone levels, and ease the psychological symptoms of PMS.
The spice saffron appears to improve both the emotional and physical symptoms of premenstrual syndrome.
The secret to naturally boosting serotonin levels in the brain may include eating foods such as pumpkin seeds, with a high tryptophan-to-total protein ratio. This may help explain why studies show that those eating plant-based diets have superior mood states.
Contrary to popular belief, the consumption of animal foods may actually decrease tryptophan levels in the brain. Carbohydrates, on the other hand, can boost transport across the blood-brain barrier, which has been used to explain premenstrual cravings.
Tryptophan is the precursor to the “happiness hormone” serotonin, so why not take tryptophan supplements to improve mood and relieve symptoms of depression?
The consumption of certain fruits is suggested as a potential treatment for depression, given the presence of psychoactive neurotransmitters such as serotonin, dopamine, and melatonin in many plant foods.
Death in America is largely a foodborne illness. Focusing on studies published just over the last year in peer-reviewed scientific medical journals, Dr. Greger offers practical advice on how best to feed ourselves and our families to prevent, treat, and even reverse many of the top 15 killers in the United States.
Excreted pharmaceutical drugs, such as Prozac, can end up polluting our waterways, and may bioaccumulate in fish flesh.
Pilot study published on whether apple juice could affect the cognitive performance, day-to-day functioning, mood, or behavior of Alzheimer’s patients.
Arachidonic acid may play a role in cancer, asthma, inflammatory bowel disease, rheumatoid arthritis, and other autoimmune disorders.
The purported role arachidonic acid plays in brain inflammation could explain why eliminating chicken, fish, and eggs may improve symptoms of mood disturbance, depression, anxiety, and stress within two weeks.
