June 17, 2014

For such a tiny snack, the humble nut carries an awful lot of baggage. Depending on who you ask, nuts are either the best thing that’s ever happened to their diet (Protein! Antioxidants! Energy!), or a sneaky source of added fat and extra calories. But we may be able to finally put the great nut debate to rest, because a new research review in the American Journal of Clinical Nutrition found that despite their high levels of fat and calories, tossing almonds on your salad or munching on pistachios to get you through your afternoon slump won't cause weight gain.

The reason: According to the researchers, nuts make you feel fuller longer, our bodies may not absorb all of the calories and nutrients in nuts, and nut consumption may even give your metabolism a calorie-burning boosts -- even when resting! (Bonus: The study found that these benefits are especially evident when nuts are consumed as a snack.)
