Superfoods are not a separate category, according to the American Heart Association. This is a marketing term used to describe foods that contain a huge amount of nutrients, few calories, little or no sugar and salt, fiber and other health boosters.

The general rule to eat healthy and cheap is to buy fruits and vegetables that are in season.

Fish is also a great go-to food but you have to be careful when and where you buy it.
