Blueberries help neutralize the effects of free radicals in the body

When it comes to superfoods, blueberries 
are the real deal.

At just 40 calories, half a cup (125 mL) of blueberries contains vitamins A and C, calcium, potassium and pectin as well as B vitamins, vitamin E, selenium, zinc and iron.

Blueberries also have the highest antioxidant content of all fresh fruits, most notably anthocyanins, which play a significant role in neutralizing the effects of free radicals (substances that affect both the development of diseases and aging in the body). 

The potent nutrient and antioxidant
 content of blueberries also:

  • Helps strengthen the immune system and build strong bones

  • Promotes urinary tract health
  • Supports eye health

  • Supports brain health by boosting the enzymes that grow new nerve cells
  • Plays a role in promoting heart health 

  • Acts as a natural diuretic 

  • Helps elevate mood

  • Improves the metabolism of sugar
  • Reduces the risk of some forms of cancer.

Fresh blueberries are available throughout the summer months and are excellent eaten as a snack, in baking, sprinkled on yogurt or added to salads. Frozen blueberries and blueberry juice are available year round.
