3 lesser-known sources of antioxidants

Kale, spinach, and blueberries all contain antioxidants, compounds that fight damaging free radicals in the body, improve post-exercise recovery, and lower the risk of disease. But here's why you should opt for these foods as well.

Rainbow Trout

The red-orange color of this fish’s fleshindicates the presence of an antioxidant called astaxanthin. It has the eye health benefits of carotenoids and similar anti-inflammatory properties as antioxidants, says Kelly Hogan, RD, clinical nutrition and wellness manager at the Dubin Breast Center at the Mount Sinai Hospital in New York City.

Whole Grains

Rye, oats, and millet add important phytochemicals like lignans and flavonoids that may protect against certain cancers.


The spud has a reputation for being a nutrient-void carb bomb, but it has many redeeming qualities, especially for athletes. They’re full of potassium and vitamin C, and some varieties like Adirondack Blue contain anthocyanins, a type of antioxidant believed to protect brain health. In general, colored potatoes (as opposed to white ones) have more compounds with anti-cancer, anti-diabetic, and anti-inflammatory properties, says Keri Glassman, RD, a New York City-based nutritionist.
