Blueberries are small round berries about 0.2 to 0.6 inches across. Their color can range from blue to purple. They are often eaten fresh but can also be enjoyed frozen, added to a wide variety of baked goods, or juiced or pureed.
Benefits of blueberry.
They have been shown to protect against heart disease and cancer, and can also help maintain bone strength, mental health, and healthful blood pressure. Blueberries contain a plant compound called anthocyanin. This gives blueberries both their blue color and many of their health benefits.
But for men especially, blueberries are king. Blueberries have lots of vitamin K, which helps your blood clot, and plenty of vitamin C like most berries. But they also may help prevent or improve erectile dysfunction, a condition that as many as half of all men will experience in their lives.
