Nuts (and seeds) make very good snacks and are healthier than a bag of chips. Although nutrient amounts vary, they contain fat (which the human body does need), protein, and vitamins and minerals, such as B-complex vitamins, vitamin E, iron, and magnesium. Some nuts are even high in omega-3 fatty acids.

Caution: One does have to be careful not to go overboard on nuts however. Eating too many nuts is hard on the liver and can slow its metabolism. This can cause acne breakouts, insomnia, and even nightmares.
