Hidden Links Between Food and Learning

peak brain function, and would likely have less dramatic results, therefore serving as a sort of unofficial control group. They were surprised to note that while the older adults showed expected results, the younger adults showed a significant improvement as well. Both groups had taken carotenoid supplements for a year, with another standard control group taking a placebo. The placebo group showed no improvement.

Lutein and zeaxanthin (which are also great for eye health) are not abundant in today’s typical Western diets. The researchers state that most people are likely getting 1-2 milligrams per day, while humans long ago probably had many times that amount. You can boost your family’s intake to reap antioxidant and anti-inflammatory benefits, as well as to increase brain function.

Where to find them

The greatest source of lutein and zeaxanthin is from dark green vegetables. The antioxidants are actually much brighter (as in the other sources listed below), but the amount of chlorophyll in these plants hides their color. Some include broccoli, spinach, peas, and parsley, with kale containing the highest concentrations.

Brightly colored foods containing the antioxidants include kiwis, squash, honeydew, grapes, red peppers, orange juice, corn, and durum wheat. Egg yolks, while not plant-based, are another great source.

To increase absorption rates, eat these foods with some accompanying healthy fats. Consider using olive oil, coconut oil, or other fats to sauté, use in dressings, or use with other foods in the same meal.
