Why do LUNA bars contain soy protein?
We choose to use soy because it is a complete source of protein, and is also vegetarian. It contributes to the balance of nutrients in LUNA bars—the balance of carbohydrate, protein, fat, and fiber that lead to a low glycemic response. LUNA bars contain 8-9 grams of soy protein. In the 8-9 grams of soy protein coming from a LUNA bar there are 9-16 milligrams of naturally occurring soy isoflavones, the phytonutrient of soy beans.
