 foods are proven to help fight depression and anxiety. The nutrients and avocados have been found to lower levels of depression, reduce anxiety, and put you in a better mood. Fermented foods like yogurt, kombucha, and some pickles have been linked to improve mental health, fewer symptoms of anxiety, and better sleep. Studies have found that people who eat fish have a significantly lower risk of depression. If sardines aren't your thing, sushi works too. Happy eating!
