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!
