Try Olive Oil
A recent study concluded that those who ate less fruit, nuts, fish, vegetables and olive oil —and instead ate more fast food and commercial baked goods— are at a greater risk of developing depression. According to another study, olive oil contains anti-inflammatory properties that may help to reduce the progression of depressive disorders.
Try Dark Chocolate
In 2009, researchers found that dark chocolate reduces the level of stress hormones. Another study showed that it produces a natural, opium-like chemical in the brain (enkephalin), which surged dramatically and remained high as long as test rats ate. More recently, researchers found that after eating a sweet (chocolate, again), subjects were more likely to volunteer to help another person; those who had a “sweet tooth” in general were more likely to be labeled as “sweet” overall. “There are some vices that are good for you,” Somer affirms. “In moderation, of course.”
Try Berries
Berries —especially blueberries and blackberries— are loaded with anthocyanidins, which are known to boost brain function, Somer says. She recommends a cup of berries several times a week. Nutrient-dense foods like berries are key to providing a sound foundation for brain chemistry, Challem says.
Try Raw Peppers
When raw, both red and green hot chilies and bell peppers are very high in vitamin C, which has shown to reduce cortisol (the stress hormone). High levels of vitamin C are also found in raw fruits like oranges, cantaloupe, papayas and kiwi.
