Protein helps you stay full longer, and everyone wants more of this muscle-building nutrient. Expect different protein sources (other than whey and soy) to show up in everything from bars to chips. Earlier this year, Lärabar introduced ALT, an energy bar made with protein from peas. And in January, Cascadian Farm will debut their organic chewy protein bars in two flavors, also made with pea protein.And now there are ips—intelligent protein snacks—made primarily from yellow corn flour and egg whites. Each 1-ounce serving boasts 7 grams of protein. Plus, they’re gluten-free. Look for more entrants in this category, from bars and cereal to smoothies and soups.
