20 Foods That Can Actually Bring You Happiness

12. Grass-fed Beef

Animals raised on grass pastures boast much higher levels of healthy conjugated linoleic acid (or CLA), a 'happy' fat that combats stress hormones and blasts belly fat. Grass-fed beef also has a lower overall fat count and contains higher levels of heart-healthy omega-3 fatty acids compared to grain-fed beef. Another great grass-fed option: lamb. It's packed with iron, a nutrient vital for a stable mood — the areas of the brain related to mood and memory contain the highest iron concentrations and iron-deficiency anemia can be a major contributor to a poor mood.
