Biochem, the well known maker of whey protein, has new protein bars that are 100 calories and certified gluten-free. They are available in three flavors: berry yogurt, caramel nougat, and chocolate truffle. I purchased the caramel nougat and chocolate truffle flavors at Whole Foods today for $1.29 each. The caramel nougat truly tastes like a Milky Way candy bar! This great chewy bar is small (.88 ounces), but satisfying.
You can view the ingredients and allergens at VitaCost. They contain milk, soy, peanuts, and tree nuts. With 6 grams of protein, 7 grams of sugar, 13 grams of carbs, and only 3 grams of fat, the Biochem caramel nougat bar is a fantastic quick and healthy snack option!
