Cognitive function, which encompasses many aspects of brain power including memory, reasoning, perception, concentration and learning ability, is a precious possession, especially as we age. Preserving your brainpower may be easier than you think. “We’re learning that if you feed your brain the right nutrients, it will work harder for you throughout life,” said Dayle Hayes, a dietitian and author in Billings, Montana.
It is well known that iron deficiency impairs brain development and learning in children. “The adult brain may also be affected by iron deficiency,” said Mary Kretsch, research physiologist with the Department of Agriculture’s Western Human Nutrition Research Center in Davis, Calif. Recent studies conducted by Kretsch and her colleagues found a decline in concentration and short-term memory associated with low iron intakes in women who were dieting. In men, as iron and zinc levels in the body declined, decreases in attention span were measured.
