Blueberries Show Potential to Repair DNA Damage

A number of studies have suggested that anthocyanin-rich foods may protect the body from DNA damage. Blueberries are a good source of anthocyanins and researchers at the University of Milan conducted a study to determine their effect on oxidative stress.

They found that consuming 200 blueberries resulted in an 18% decrease in oxidative stress related DNA damage to blood cells.

The study included 10 participants who were given either 200 ground blueberries or a jelly as a placebo. The researchers took blood samples before the participants consumed the blueberries or jellies, and then one, two, and 24 hours after ingestion.

At the one hour mark they found that the blueberry group had an 18% reduction in DNA damage compared with the control group. They did not, however, find any difference after two or 24 hours.

The study was published online ahead of print on February 4, 2013, in Nutrition Research.

There are numerous other reasons to eat more blueberries. Blueberries have been shown to decrease the risk of dementia, aid in weight management, improve blood vessel function, lower blood pressure and reduce cholesterol.

They are easy to add to your diet because they go well with pancakes, salads and smoothies.
