All tomatoes are a great source of lycopene, a fat-soluble phytonutrient that helps protect vital brain fat, and a nutrient that actually stops the buildup of pro-inflammatory compounds linked to depression.

Just be sure to always choose organic. Trials at University of California–Davis have found that organic tomatoes have higher lycopene levels.
