What are Superfoods and Why are They Healthy?


‘Superfoods’ is a term you probably have heard countless times. This word has been around since World War 1, but it’s become even more popular recently. Thanks to the growing food industry, it may not be going anywhere soon.

In this article, we’ll tell you everything you need to know about superfoods – Types, examples, benefits, and side effects.

What are Superfoods?

Superfoods are unprocessed foods with high-density nutrients and minimal calories. They are loaded with antioxidants, vitamins, minerals, and can help you meet your daily nutritional demands.

The high amount of antioxidants, phytochemicals, minerals, and vitamins present in these foods improve immunity and general wellbeing. However, they should not replace a healthy and balanced diet.
