Aronia berries among the latest 'superfoods'

Antioxidants have long been known to play an important role in healthy aging, and experts believe they have uncovered a new food that is one of the best sources of these vital nutrients. Aronia berries contain a number of antioxidants that can help improve seniors' health in a variety of ways, from preventing cancer and chronic inflammation to reducing the risk of cardiovascular disease and liver dysfunction, Yahoo reports.

Experts say aronia berries are a bit more tart than other similar fruits, but they also contain about twice as many antioxidants as cranberries and four times as many as strawberries. In fact, it's that tart taste that is indicative of its considerable health benefits. 

"It's very similar in taste to a wine grape," wellness expert Tammy Ross told Yahoo. "What you're tasting in that tartness is actually very good for you - a type of an antioxidant and type of a compound that can be found in wine and can also be found in tea."

Of course, aronia berries aren't the only good source of antioxidants for seniors. While fruits and vegetables are the most obvious choices, according to the United States Department of Agriculture, nuts and spices are good options as well.
