8 Foods Rich in Antioxidants

Updated on July 31, 2017

What Are Antioxidants?

Antioxidants are molecules that inhibit oxidation. Oxidation produces free radicals that are known to damage cells. Antioxidants are key to protecting the cells from damaging and ageing.

Antioxidants Prevent Many Diseases

These powerful substances prevent many diseases. Vitamin C, beta carotene and vitamin E are some well-known antioxidants.

How Do Antioxidants work?

Unstable free radicals damage cells. Antioxidants neutralize free radicals by donating their electrons to free radicals.

Consuming foods that have high antioxidant properties can help mitigate free radical damage.

Antioxidant Foods


Antioxidant-Rich Foods

One secret to good health is consuming foods that contain antioxidants. These foods are foundations of a healthy diet. Here are eight of them:

Goji Berries

Also known as wolfberry, goji berry is a bright red edible berry. It is usually dried and used in beverages. With an Oxygen Radical Absorbance Capacity (ORAC) score of 25,000, goji berry is an excellent source of antioxidants. ORAC is a unit of measurement of antioxidant content in foods.

Goji Berries Contain Essential Amino Acids

There are many good sources of antioxidants, but what makes goji berries stand apart is their amino acids (protein), fatty acids and specific antioxidants. It is not common for a fruit to provide amino acids, especially 11 types considered “essential” that the body cannot produce.

This will definitely delight chocolate lovers. Dark chocolate has an ORAC score of 21,000. "Cocoa is rich in antioxidant flavonoids called flavanols, which include procyanidins, epicatechins, and catechins," says Harold Schmitz, PhD, Director of Science at Mars, Inc.

Pecan, which is technically a drupe, is smooth and has a pinkish-brown color. The antioxidant-rich pecans have been consumed by American aborigines for centuries. ORA score: 17,000.

Antioxidants in Pecans Prevent Diseases

A research study conducted in 2011 at the Loma Linda University suggests that antioxidants in pecans promote heart health and prevent diseases. Including pecans in your diet enhances the amount of antioxidants in the body and reduces LDL, the “bad” cholesterol.
