Native to the United States and Canada, this small berry could be one of the most antioxidant-rich fruits. The pigment that makes blueberries blue (anthocyanin) is thought to be responsible for this fruit's superior antioxidant benefits. The months of May through October are the height of the blueberry season and usually produce the freshest version of the fruit.
Cultivated blueberries are known for their sweetness, but those that grow wild are often more tart and tangy. Blueberries were not enjoyed by consumers until the middle of the 19th century when sugar became more widely available, and the taste could be altered from tart to sweet. It was not until 1916 that blueberries were cultivated and became available commercially.
Blueberries contain essential nutrients such as Vitamin C, an antioxidant that has many functions, such as the promotion of healthy skin and gums and the ability to increase iron absorption.4 Blueberries are also a source of fiber, which helps to maintain a healthy digestive system.
