In one of the first studies to examine the relationship between diet and brain lesions,researchers observed that elderly people who reported higher calcium and vitamin D intake were much more likely to have greater volumes of brain lesions-regions of damage that increase risk of cognitive impairment."Our finding of a relationship between brain lesions and consumption of both calcium and vitamin D raises the question about a possible down side to high intakes of these nutrients,"Martha E Payne of Duke University,Durham,North Carolina,said.Higher intakes of calcium and vitamin D have been promoted in recent years as a way to prevent bone loss with ageing.
