Health news: vitamin D

Could vitamin D ease ulcerative colitis? Researchers conducting a clinical trial at the University of Chicago believe it will boost the malfunctioning immune system thought to lie behind the disease. Ulcerative colitis is a chronic inflammatory bowel condition where the immune system attacks healthy tissue, leading to inflammation and ulcers. Earlier studies have shown that vitamin D (which the body makes when skin is exposed to sunlight) has a beneficial effect on the immune system. Half the patients will take a high daily dose of vitamin D for eight weeks, the rest will take a placebo.

(High doses should be taken only under medical supervision, as they can trigger nausea and heart complaints.)
