Lycopene may lower stroke risk in men. Foods such as tomatoes, guava, watermelon, and grapefruit are good sources of lycopene. When tomatos are cooked, the heat processing increases levels of cis-lycopene, which is easily absorbed by the body.

As per a report published in Oct. 9 issue of Neurology, by Jouni Karppi, PhD, of the University of Eastern Finland in Kuopio, compared with the men who had the lowest serum concentrations of the carotenoid, those with the highest concentrations had significantly lower risks of stokes.
