They are high in antioxidants, vitamins C and K, and fiber, making them a healthy addition to any diet. Blueberries can be eaten raw as a snack or in salads, or used in a variety of dishes like pancakes, muffins, and smoothies. When selecting blueberries, look for plump, firm, and smooth berries that are free from mold or mushy spots.

To prepare blueberries, rinse them gently under cold water and remove any stems or leaves. Enjoy them as a snack, or add them to your favorite recipes for a sweet and nutritious boost.
