Let food be thy medicine, thy medicine shall be thy food. ~Hippocrates

1. Eat complex carbohydrates

Eat complex carbohydrates at each meal and eat enough of them. By doing this, you are stimulating the pancreas to evenly let out insulin. Make sure these carbs are unrefined.  Think salad rather then sandwich.  Fruits vegetables and even beans are more effective then crackers.

Nothing will benefit human health and increase the chances for survival of life on Earth as much as the evolution to a vegetarian diet. ~Albert Einstein

2. Watch your oils

Make sure you get them from a healthy source.  While you might crave fatty, fried foods when you are really stressed, or depressed, go for unaltered, untreated fats like avocado, raw nuts, raw seeds or unheated oils.  The brain needs these essential fatty acids to function optimally.

3. Limit the gluten, dairy, corn and sugar

Other things to limit are gluten, dairy, corn and sugar.  They are mood changers. When you eat foods that are denatured and irritate the intestine, you compromise your digestion and absorption levels.  That means that you have lowered your ability to absorb nutrients that would make you feel better like folic acid, tryptophan and D.

Those who have no time for healthy eating will sooner or later have to find time for illness. ~ Edward Stanley

4. Make sure you get enough:

Nuts

• Oils in nuts and seeds help the body make prostaglandins, which are actually hormones.  These hormones are the ones that help with your responses to the brain, stimuli, and other hormones.  Essential fatty acids in nuts and seeds also help build neurotransmitters.
• Limit nuts to 10 or fewer per day, as there is a tipping point where too much is too much.  Too many nuts will sludge up your system.

Greens

• Contain tons of B6 and vitamin C.
• Is a great source of folic acid.
• Greens help the body create tryptophan.
• They stimulate more serotonin production (anti-depressant neurotransmitter).
• Contain phytonutrients that help the brain’s electro-chemical signals.  -Sodium and potassium are high in greens and actually carry electrical signals down each neuron.
• Greens give neurons amino acids, which build neurotransmitters.

Workout 

• Hard vigorous workouts help relieve depression.
• It releases endorphins, which are mood boosters.

 5. For an extra Boost 

• Try a micro-algae supplement with DHA and EPA or cold-water fish.
• If you have SAD (seasonal affected disorder) use a light box.
• Play with eating more starches, fat or protein.
• Supplement with Tryptophan, 5-HTP, D, B6.
