One of the biological causes of depression is the presence of certain inflammatory compounds in the brain. Researchers are not yet sure what causes this inflammation, however, it is known the antioxidant lycopene found in tomatoes reduces these compounds. Lycopene is responsible for giving tomatoes their red color.

Tomatoes also promote a healthy gut microbiome and digestive tract because of their fiber content. They also contain vitamins and minerals that support the production of happy hormones, including iron, folate, Vitamin B6, and magensium. Their natural sugars and B vitamins are also great for an energy boost.
