“Brain food” meals and snacks make you smartest, most alert, and least distracted by hunger. Fast food, and most restaurant meals, and packaged, processed foods are anti-brain foods.
Brain foods raise blood sugar to optimal levels and maintain it for hours. These include quality protein (egg whites, most fish, skinless white meat chicken, unsweetened Greek yogurt), whole grains (wheat berries, rye kernels, whole oats), and healthy fats (avocado, nuts, nut butters).
Anti-brain foods include added sugars, saturated fats (including coconut and palm), and simple carbs (white flour, white rice, white potatoes) that rapidly convert to sugars. These make you sluggish. Most unhealthy foods contain “addictive” combinations of sugar, salt, and fat.
Protein or energy shakes, or smoothies, are not meals. The more liquid and softer food is, the more you eat and the less focused you become. Caffeine, while temporarily improving focus, quickly wears off, causing a “crash”.
