Nuts are bite-sized powerhouses loaded with good fat, protein, vitamins and minerals to keep you fueled. These concentrated sources of energy deliver around 160 to 200 calories per small handful, making them a perfect on-the-go snack. Nut butters are also great options, and they can easily be mixed into smoothies, added to fruit, or spread between two slices of bread for a quick and easy meal.
But this doesn't mean you can eat as many nuts as you want. Not all nuts are healthy, and they're all high in calories, best eaten in moderation, raw or dry roasted, and in combination with whole grains for a complete protein and essential amino acids. Eat a variety, because they have different health benefits.
