Healthy fats are like fuel for a good mood. They’re one of the most important things to include in your diet to promote a healthy mood (and a balanced metabolism). Healthy fats also promote good heart health, reduce cholesterol, and contain none of the harmful side effects associated with animal-based saturated fats. Go for raw coconut, avocados, almonds, walnuts, acai fruit, flax seeds, cashews, hemp seeds, chia seeds, pumpkin seeds, sesame seeds or tahini, pecans, and olives.
