A popular new ingredient in gluten-free products could be causing an allergic reaction, says a food-safety specialist at Kansas State University, Manhattan.

Lupin, a legume belonging to the same plant family as peanuts, is showing up as a wheat replacement in an increasing number of gluten-free products. The U.S. Food and Drug Administration (USDA) is issuing an alert, urging consumers with peanut and soybean allergies to read labels before buying these products.

“Lupin is a yellow-colored bean that's very popular in Europe, Mediterranean countries, Australia and New Zealand,” says Karen Blakeslee, KSU extension specialist in food science and coordinator of the Rapid Response Center. "However, it is new to the United States and because of that, many consumers have never heard of it and may not realize that lupin has the same protein that causes allergic reactions to peanuts and soybeans."

Allergic reactions can have various symptoms, including hives, swelling of the lips, vomiting, breathing difficulties and anaphylactic shock. Even those without allergies to legume products need to be aware of the ingredient.

"You can become allergic to something at any point in your life," Blakeslee says. "If you do start seeing any symptoms of an allergic reaction, stop eating the food immediately and contact your doctor."

The FDA expects lupin to become a popular product in the gluten-free arena because of its many health qualities. It is high in protein and dietary fiber, which helps lower cholesterol, and low in fat.

Manufacturers are required to list lupin on their food labels. The FDA is actively monitoring complaints of lupin allergies by U.S. consumers.
