16 fruits and vegetables for a sharper memory

While vitamins and supplements are essential to Limitless physiology, our bodies are designed to pull nutrients from organic fruits and vegetables.

So it is essential to eat in-season, locally-grown foods along with supplements to feed our minds everything that they need. Vegetables and fruit are packed with antioxidant vitamins along with minerals and fiber. Experts urge you to eat as much and as many fruits and veggies as you can pack in—10 servings if you want. A serving is one whole fruit or vegetable, a half-cup cooked or 1 cup raw greens.

Psychology Today encouraged readers to think about color when browsing the produce aisle at the grocery store. Brightly colored fruits and vegetables are high in vitamins, minerals, and phytochemicals.

A lot of the foods below are rich in the phytochemical anthocyanin.

Anthocyanin-rich fruits and vegetables are usually red, purple, or blue. Anthocyanin is a great thing to put in your body; not only does it boost memory, but it's also an antioxidant that fights cancer, aging, neurological diseases, inflammation, diabetes, and bacterial infections. Interestingly, phytochemicals benefit our mind and body synergistically in whole-food form. This means that the benefits from the nutrients in fruits and vegetables, when consumed in whole form, are greater than the sum of their parts. It has not been conclusively proven that we can get anthocyanin and the needed phytochemicals from supplements, so it's necessary to eat a diet high in fruits and vegetables.

Tip: If you don't have the time, patience, or expertise to prepare fruits and vegetables for consumption make a healthy shake with a blender. Add your protein, your whole food fruits and vegetables (make sure to eat the skin as well), and blend away! Blending whole foods is superior to juicing. Juicing isn't bad for you but it removes a lot of the important nutrients.
