Blueberries are an incredibly delicious and nutritious fruit. Much research has highlighted their numerous health benefits, and now a collection of studies, published in The Journal of Gerontology: Biological Sciences, point to their role in easing the effects of aging.
Blueberries are loaded with vitamins and minerals, but it’s the antioxidants they contain that make them such a nutritional powerhouse. They are thought to have one of the highest levels of antioxidants of any fruit or vegetable. The particular group of antioxidants in blueberries believed to be responsible for their beneficial health effects is called anthocyanins, a type of flavonoid that is found naturally in foods that are red, purple and blue in color.
In one study of about 200 older adults with an average age of 65, after an assessment of their ability to recall certain information, half of the participants were given a supplement containing an extract from grape and wild blueberry, while the other half was given a placebo for six months.

In a separate study using rats that were fed a blueberry powder, aged-related deficits in cognition were shown to be thwarted in those with normal abilities or reversed in those with decreased cognition.
Previous research has found similar health benefits for blueberries which is why it’s often included on a list of “super foods.” If you’re not eating blueberries often, the research findings may cause you to stop and ask yourself, “Why not?”
Blueberries are available in the grocery store year-round in the frozen food section. When they are in season, bargains can be found in the produce department.
Blueberry farms are another place to stock up on this delicious berry. You can pick them yourself or buy them in quantity to take home and freeze. Blueberries last in the freezer at peak quality for a year, but as long as they are kept frozen, they will last indefinitely.
