Diet - poor: It is important for thinking and lifestyle to have all the food groups in your day to function at your best level. Fluids, water is very important- 48-64 ozs/d. Also, protein as in meats, milk, tofu. carbs - fruit, fats - avocado, olive oil, vegetables broiled/steamed and whole grains (pasta without white flour). This will be your best nutritional balance.
