A Low Methionine Diet: New Data for Cancer Therapy Favors Plant Foods
Amino acids are the building blocks of all proteins in the body. A subcategory of amino acids contain sulfur and includes methionine (Met) and cysteine, which not only make up proteins but also play many roles in metabolism and health. Researchers have been interested in dietary sulfur amino acid restriction since the 1990s, when studies began to show health benefits in animals fed Met-restricted diets. In one early study involving rats, 80 percent Met restriction increased average and maximum lifespans by between 42 and 44 percent…
