    Dr. Dean Ornish answered:
    Nutrition also affects your neurons - for better and for worse. A diet high in sugar and saturated fat diminishes neurogenesis, whereas other foods increase it, including chocolate (in moderate amounts), tea, and blackberries, which contain a substance called epicatechin that improves memory. Small amounts of alcohol increase neurogenesis, whereas larger amounts decrease it. Chronic emotional stress decreases neurogenesis, but stress-management techniques increase it. Drugs such as nicotine, opiates, and cocaine decrease neurogenesis, whereas a study published in the Journal of Clinical Investigation in 1995 showed that cannabinoids (found in marijuana) may increase it, at least in rats. (Uh, what were we just talking about?)
