Tests Have Shown That Mushrooms are Gluten Free

What is Gluten?Nutrition can be confusing, with conflicting information in the news, including what it means to be gluten intolerant versus being diagnosed with celiac disease. Understanding what is gluten free and what isn’t can also take research and time. Simply said, like all fruits and vegetables, mushrooms are naturally gluten free, and make a delicious and nutritious addition to a gluten free diet.

Mushrooms, just like any other vegetable, should be cleaned before consuming. If you see little specks on the surface of the mushroom simply rinse under cool water or wipe with a damp cloth.

Beyond Gluten Free

Mushrooms are naturally free of gluten, sodium and cholesterol, and are also a source of some very important nutrients.

Mushrooms are a source of B vitamins, including riboflavin, niacin, and pantothenic acid. These B vitamins help to provide energy by breaking down proteins, fats and carbohydrates(2).

Mushrooms are also a source of important minerals such as; selenium, a mineral that works as an antioxidant to protect body cells from damage(2). Many foods, of animal origin and grains, are good sources of selenium, but mushrooms are among the richest sources of selenium in the produce aisle. Ergothioneine (2.8-4.9 mg) is another naturally occurring antioxidant that also may help protect the body’s cells.

Potassium is another important mineral many people do not get enough of. It aids in the maintenance of normal fluid and mineral balance, and can help control blood pressure(2).

Beta-glucans (long chain carbohydrates) found in numerous mushroom species*, have shown marked immunity-stimulating effects, may contribute to resistance against allergies and may also participate in physiological processes related to the metabolism of fats and sugars in the human body(3).

Mushrooms exposed to the sun or UV light to naturally develop vitamin D, are the only source of vitamin D in the produce aisle and one of the few non-fortified food sources.

Enjoy a gluten free diet that includes mushrooms to help maintain a healthy body.

Labeling Foods as “Gluten Free” the Final Rule

The Food and Drug Administration is issuing a final rule to define the term “gluten free” for voluntary use in the labeling of foods. The final rule defines the term “gluten free” to mean that the food bearing the claim does not contain an ingredient that is a gluten-containing grain (e.g., spelt wheat); an ingredient that is derived from a gluten-containing grain and that has not been processed to remove gluten (e.g., wheat flour); or an ingredient that is derived from a gluten-containing grain and that has been processed to remove gluten (e.g., wheat starch), if the use of that ingredient results in the presence of 20 parts per million (ppm) or more gluten in the food (i.e., 20 milligrams (mg) or more gluten per kilogram (kg) of food); or inherently does not contain gluten; and that any unavoidable presence of gluten in the food is below 20 ppm gluten (i.e., below 20 mg gluten per kg of food).
