Key Superfoods for Optimal Health

There are healthier foods and not-so-healthy foods. Additionally, some foods may significantly boost health and even help manage health conditions. Such foods are called superfoods or functional foods. The benefits of including these foods in diet extend beyond their nutritional value.

The Impact of Superfoods on Health

Superfoods are not just about preventing most chronic health issues like heart disease, stroke, and metabolic disorders, but they also reduce cancer risk. Since they are good for immune health, they also help fight infections, allergies, and autoimmune disorders. They also have anti-aging effects; thus, one does not have to live with diseases to enjoy their health effects.
