What are Antioxidants?

Antioxidants are molecules that combat free radicals in our body. Free radicals are unstable molecules that can damage our cells, leading to oxidative stress, a precursor to many chronic diseases.

Anthocyanins: The Star Compound

Blueberries are particularly rich in a group of flavonoids called anthocyanins. These compounds not only give blueberries their characteristic blue hue but also have potent antioxidant properties. They neutralize harmful free radicals, thereby preventing cellular damage.

Comparative Analysis with Other Foods

When compared to other fruits and vegetables, blueberries consistently rank high in terms of antioxidant activity. This means, gram for gram, blueberries offer one of the most effective natural defenses against oxidative stress. The table below provides a snapshot of how blueberries compare with other fruits in terms of nutritional content and health benefits. It’s essential to note that all fruits have their unique set of benefits, and variety is key to a balanced diet.
