5. Oysters
Oysters contain high levels of zinc, an important nutrient that is at least as effective as SSRIs in treating major depression, according to these studies. The Mayo Clinic recommends at least 8mg for women and 11mg for men daily. A single raw oyster contains 5.5mg of zinc, so just two or three are more than enough to meet the recommendation.

Just A Pinch.
Zinc aside, oysters are also packed full of Omega-3 fatty acids. Omega-3s improve the level of important hormones including DHA in the brain which regulates things like metabolism and mood. Furthermore, they fight inflammation that causes neurodegenerative diseases like Parkinson’s, Alzheimer’s, and dementia.
