Superfood Blueberries

Blueberries were one of the first foods to be known as a superfood because of their high antioxidant levels. It’s these antioxidants that makes them such a healthy food.

Many of the health benefits of blueberries is down to anthocyanins, a potent flavonoid, which is one of the main antioxidant compounds. The darker color the blueberries are the more antioxidants they have.

Health benefits of blueberries

The health benefits include their anti-inflammatory effect, preventing heart disease, bone strength, skin health, lowering blood pressure, diabetes management, improving memory, brain function and cancer prevention.

Not so good for some is the fact that blueberries contain very high amounts of salicylates. This is a natural compound which can cause side effects such as gastrointestinal symptoms in people who are sensitive to them.

Different varieties can be found growing in different parts of the world. Cultivated blueberries are sweeter than those growing in the wild.

Should you buy organic blueberries?

Organic produce contains more nutrients than non organic and does not contain any pesticide residue. Blueberries do not figure on this year’s EWG’s Dirty Dozen but they don’t figure on the Clean Fifteen either.

In the opinion of Dr. Carl Winter, a professor of toxicology at the University of California, Davis the amounts of pesticides found on the Dirty Dozen list are too small to merit concern in the first place.

On the other hand What’s On My Food website list a number of pesticides that have been found on blueberries that could affect health. 52 pesticide residues were found by the USDA Pesticide Data Program although the figures for blueberries were from 2008.

Nevertheless EWG states that in fertility studies’ classifcation of pesticide residues done by researchers from Harvard University using USDA test data, blueberries were classified as haivng high pesticide residue score.

So there you have it. Best to buy organic if you can. If not then it’s best not to eat too many blueberries and other produce that is on the EWG’s Dirty Dozen list.
