What we eat is crucial to how we feel.

Say yes to dark leafy vegetables and no to chemicals, alcohol, milk and other dairy, sugar substitutes, and caffeine. (Coffee and energy drinks are never OK as fuel.)

Choose good fats like avocado, coconut oil, extra virgin olive oil, seeds, almonds, and nuts. We need fats and cholesterol to make hormones. Cholesterol improves cell membrane integrity, brain function, serotonin and dopamine production, meaning we are less depressed.

You need a ton of protein as you age. The more protein, and the less starch and sugar, the better. Protein is fuel for the brain, muscles, bones, and hormones. Protein that comes from vegetables, fish, and supplements is the best.

One common trait of people taking antidepressants is that they eat a lot of starches and sugar. Obesity and illness is a constant problem. Correct the diet and the depression will decrease — no drugs required.

Supplements can also help boost mood: fish oils, BCAA, and omega-3 and -6; vitamins C, D, and B12; 5 HTP; SAMe; carnitine, coenzyme Q10; probiotics; quercetin; phosphatidylserine, choline; L-glutamine; and iodine, among others.
