In a┬ánew study, researchers have identified a key molecular mechanism behind the health benefits of dietary restriction — or reduced food intake without malnutrition. Also known as calorie restriction or simply a diet, dietary restriction is best known for its ability to slow aging in laboratory animals. The findings here show that restricting two amino acids, methionine and cysteine, results in increased hydrogen sulfide (H2S) production and protection against ischemia reperfusion injury, or damage to tissue that occurs following the interruption of blood flow as during organ transplantation and stroke. Increased H2S production upon dietary restriction was also associated with lifespan extension in worms, flies, and yeast.
