Need a healthy snack you won't find addicting? Then peanuts should be your pick. Why? Because they don't cause a direct release of the pleasure neurotransmitter dopamine, like some foods do -- foods like sugary cereals, which release dopamine, make you feel great, and then cause you to crash and reach for more of the item that made you feel so good. Not the case with peanuts.

Peanuts satisfy without a roller-coaster effect. They're also good for your heart, full of healthy fats, and powered with antioxidant and anti-inflammatory goods. Just an ounce of peanuts per day will do you good, minus the major cravings.
