Blueberries, blackberries, acai berries and more

By Mark Goodman

1. Blueberries

Blueberries are really a no-brainer if you're looking for a fruit high in antioxidants. A favorite pie ingredient of North American grandmothers. They are available at most any grocery store in the US and the cheapest of those on our list. I personally eat a bowl of them a day just because I enjoy the taste so much. The ORAC rating for one cup of cultivated blueberries has been listed at 9019.[1] The ORAC rating for one cup of wild blueberries is listed at 13427.[1]

2. Blackberries

Although generally more difficult to find than blueberries, blackberries are another well known berry which contains a very high concentration of antioxidants. The ORAC value has officially been listed at 7701 per cup.[1] Most often you will find blackberries in a berry mix along with raspberries and blueberries.

3. Cherries

With an ORAC value listed at 4873[1] per cup, cherries are high on the list of antioxidant-rich berries. As the favorite berry of many, there is no mistaking their sweet taste, but knowing how beneficial they are for your health should provide even more incentive to grab a bunch next time you're at the grocery.

4. Wolfberries

Cultivated and eaten for centuries in China, wolfberries are relatively unknown outside the region. Wolfberries are probably more recognizable by the name goji berries in North America where they have been marketed as a miracle berry in a way similar to acai and noni. While they surely have high antioxidant value, the actual ORAC rating has not yet been confirmed by an independent study.

5. Acai berries

Made popular recently by Oprah and internet marketers everywhere, acai is another berry which is high in antioxidants. As with wolfberries, to ORAC value of acai berries has not been confirmed by an independent study, it would probably be safe to assume their antioxidant value lies somewhere equal to or above that of blueberries. They do taste good and the juice has a semi-sweet flavor which even tastes like it's good for you. Considering how long they have been cultivated an eaten in South America, they must have some merit besides flavor.

6. Noni berries

You might be most familiar with noni in juice form. It's common to see noni juice all over health food stores, but the berries themselves are rather difficult to find. While the noni berry is high in antioxidants, what you may not know is that the ORAC rating for them is less than the rating for oranges.[2] I've included noni in this list to make people aware that the common blueberry most likely has more antioxidants than the noni berry.

When thinking about how healthy a berry or fruit might be for you, it would be wise to also consider and research the concentrations of phytochemicals, flavonoids and xanthones. Probably the best decision would be to consume a variety of berries and fruits so you receive all the benefits. Some berries and fruits might even have synergistic effects when eaten together.

  1. I remember that show of Oprah Winfrey in which explained how powerful the juice of Acai berry for human health is. Since that episode, Acai Berry Juice became popular. Now everyone is taking it in the morning and curing/preventing many kinds of health related problems.
