Stress-prone? Altering the diet may help
Some people undertake seemingly impossible tasks without frustration, while others become anxious or depressed. A Dutch study now finds that the latter individuals might cope with pressure better if they tailored their diet to fuel the brain with more tryptophan. The brain uses this essential amino acid, a building block of many proteins, to fashion […]

Fighting cancer from the cabbage patch
Sauerkraut a health food? Not yet. But midwestern scientists have found evidence that something in this pickled cabbage and related foods blocks the action of estrogen, a hormone that can fuel the growth of breast cancer and other reproductive-tract malignancies. Nutritionist William G. Helferich of the University of Illinois at Urbana-Champaign and his colleagues were […]
