Spreading PB on fruit or whole-wheat toast is a smart snack, but many popular brands have a hidden ingredient that can lower levels of “good” cholesterol and make your “bad” cholesterol levels skyrocket: “If it’s not natural, there can be trans fats in peanut butter, and a lot of people don’t know that,” says White. “Even if it says ‘zero trans fats’ on the label, if it’s fully hydrogenated, which a lot of your peanut butters are, there can still be 0.5 grams of trans fats.”
Stock this instead: Natural peanut butter
Read the ingredient list before you pick one. The list should have three things and three things only: peanuts, salt, and oil, says White.
