4. Ancient grains
Eat it for: The complex carbohydrates
Examples: Quinoa, millet, teff, amaranth, spelt, barley
Why they help: Complex carbohydrates take longer to digest, which means they don’t cause spikes in blood sugar that can create roller-coaster moods. Complex carbs also increase levels of serotonin in the brain.
While any whole grain is good, so-called “ancient grains” are even better, according to Reardon, because they’re less likely to be man-modified and processed. Packaged, processed, and refined foods made with wheat flour and sugar, in contrast, tend to be digested quickly, causing cause blood sugar to spike. When this happens, the body responds with an oversecretion of insulin, which winds up moving too much sugar into cells — and blood sugars plummet. The end result: poorer concentration, fatigue, mood swings, intense cravings, and overeating.
Ancient grains are increasingly available at mainstream grocery stores and big-box stores such as Costco and Sam’s Club. Look where rice products are shelved. Many ancient grains can be cooked like pasta or rice and served in their place as side dishes, in casseroles, or as a base for fish or chicken.
Bonus: Some ancient grains are a whole-grain alternative for those who are allergic to wheat or have gluten intolerance. (Barley, though, contains gluten.)
