Almond Milk

Thirty million Americans are gluten-intolerant or have a gluten sensitivity, eliminating it from their diets because gluten—a protein found in wheat, rye, and barley—has been implicated in health issues ranging from respiratory problems and abdominal discomfort to anemia, anxiety, and infertility. The food industry has bullishly taken notice. Gluten-free baking products, including cake mixes from Betty Crocker, King Arthur, Whole Foods, and others, have increased sevenfold on grocery shelves in recent years, and the number of other gluten-free products has grown as well—832 were introduced in 2008 alone. And gluten-free options are on the menu of national restaurants like Boston Market, Chili’s, Ruby Tuesday, Outback Steakhouse, and others.
