3. Lettuce
There’re several varieties of lettuce. Some say that lettuce is not the richest source of nutrients. This is not true at all, especially if we’re talking about purple lettuce. Dark green lettuce is also a great option. Experts recommend we all should eat romaine lettuce since this variety provides folic acid, manganese and vitamin B. The best thing to do is to mix different type of lettuce and prepare salads.

4. Quinoa
Quinoa is gaining popularity. A few years ago it wasn’t sold in supermarkets and only few of us knew what it was. This grain crop is a fantastic way to lose pounds. There are less than 200 calories in one serving of cooked quinoa. This food has a relatively low glycemic index and belongs to the list of food with slow carbs.
