BRISTOL, England, Feb. 9 (UPI) -- A diet in early childhood high in fat, sugar and processed foods may lower IQ, but a diet high in produce and grain may raise IQ, British researchers suggest.
Researchers at the University of Bristol's School of Social and Community Medicine in England analyzed data from the Avon Longitudinal Study of Parents and Children, which tracks the long-term health and well being of some 14,000 children born in 1991 and 1992.
