New Prague dietitian explains the benefits of blueberries

July 29, 2016



NEW PRAGUE, Minn. — Often labeled a superfood, blueberries are bursting with vitamins and minerals, many of which are classified as antioxidants. Allie Wergin, registered dietitian nutritionist at Mayo Clinic Health System in New Prague, encourages community members to start eating more of these powerful little berries. She provides the following facts and advice, as well as a healthy recipe:

Much of the power of blueberries lies in their colors. The deep-blue hue comes from anthocyanin, an antioxidant that could help protect the body from heart disease and cancer, as well as reduce inflammation and increase immune function. Research also suggests the compounds found in blueberries may delay the effects of vascular dementia or Alzheimer’s disease.

A half-cup cup serving of blueberries contains 25 percent of the recommended daily value for vitamin C and 3 grams of dietary fiber — and only 30 calories. In addition, blueberries are a juicy fruit, which means they contain mostly water. Juicy fruits are great for weight loss or weight maintenance, because they fill you up quickly with their high water content and minimal calories.

Whether you’re eating blueberries for the health benefits, because you like the taste or both reasons, blueberries can easily be eaten plain. They can also be added to cereal, yogurt or incorporated into baked goods for added sweetness and nutrition. To prolong the shelf life, keep blueberries refrigerated.

During these summer months, be sure to take advantage of blueberries when they are plentiful and on sale by purchasing in large quantities and freezing them. Just wash and dry the berries, lay them on a pan, and freeze until they’re solid. Package frozen blueberries in freezer-safe storage bags so they’re ready for the winter months. You can easily substitute frozen berries for fresh.
