Early dietary interventions can improve blood-vessel function in boys.

The American Heart Association's journal Circulation, finds that a low-fat diet is associated with better endothelial function in boys.

Dr. Olli T. Raitakari, from the University of Turku in Finland, and colleagues note the importance of this finding and its implication in the timeliness of dietary intervention.

"Early nutrition may play an important role in the later vascular health of males."

"It may be associated with less atherosclerosis and a lower future risk of cardiovascular diseases."
