Include foods that supply essential fatty acids. Raw or dry roasted nuts and seeds are one source. These would ideally include fresh, raw, refrigerated walnuts, pumpkin seeds, and flax seeds or flax meal, along with all the other nuts and seeds. Cold-pressed oils of these nuts and seeds would also be good. Eat products such as seaweeds and fish that are rich in omega-3 essential fatty acids – salmon, sardines, trout, tuna (only small amounts), herring, and mackerel. Avocados, fresh coconut, and extra virgin olive oil are also good sources of fat. Avoid trans fats .

Animal foods contain variable amounts of fat. To maximize the essential fatty acid content (and consume a healthier food), try to get the meat and dairy products of animals that were raised as naturally as possible. "Free-range" animals are allowed to forage on green grasses, so their diet – hence their meat, milk, and eggs – are rich in essential fatty acids and superior to that of caged animals. Look for wild fish, rather than farmed.

Animal foods, including eggs and milk products, are excellent sources of protein and, thus, the amino acids that come from the breakdown of protein. Other foods supplying many of the essential amino acids needed for neurotransmitter production are dried beans (legumes), green leafy vegetables, whole grains, nuts, and seeds.

To maintain adequate levels of the brain fuel glucose, it's important to eat often enough. For some people, this means eating snacks as well as main meals. For others, it just means eating at least every five hours. Poor concentration and low energy levels can be a sign that it's been too long since your last meal.

Nutritious foods can also be high on the glycemic index . These include starchy vegetables such as corn, potatoes, winter squash, and cooked or juiced carrots and beets. Whole grains and whole grain breads, cereals, and crackers are also healthy high-glycemic foods.

One formula for avoiding blood sugar spikes from these carbohydrates is to combine them with protein foods. For example, have an egg with your piece of toast; a tempeh burger with your ear of corn; a serving of salmon along with your potato. Mix high-glycemic fruits or fruit juices in a blender with nuts and whey protein powder. Non-starchy vegetables are also stabilizing to blood sugar levels. Eat them steamed or raw, in salads or stir-fried.

Most foods contain some vitamins and minerals, but micronutrients are especially abundant in fruits and vegetables. To ensure a plentiful supply of these antioxidants, include at least the recommended five servings of fruits and vegetables every day. (Better yet, the ten servings sometimes advocated for cancer prevention.)

A serving is generally a small fruit or half a cup of cubed fruit; a cup of raw green leafy vegetables or half a cup of cooked greens; a half cup of other cooked or raw vegetables. These fruits and vegetables should be of wide variety and color – preferably in season, organic, and locally grown.

These meals are designed to provide a balanced and nutritious diet for the brain and body that minimizes blood sugar spikes. (Snacks are included for those who need them.)

People vary greatly in their response to different foods, therefore the following menu recommendations are not necessarily suitable for everyone. Experiment, and learn what works best for you.

If you're not used to this much roughage, then transition slowly from your accustomed eating pattern to one such as this.
