What is gluten?

Gluten is a protein complex found in the grains wheat, barley, rye, spelt, and triticale. Flours made from these grains are commonly used to make foods such as breads, cereals, pasta, pizza, and baked goods. The gluten in these foods gives them the elastic texture and it helps provides the structure of the food.

 

Why would someone need to follow a gluten–free diet?

Anyone with celiac disease should follow a gluten–free diet.

 

What is celiac disease?

Celiac disease is an autoimmune disorder that is triggered when gluten–containing foods are eaten. An autoimmune disorder is one in which the body’s immune system attacks an organ. When a person with celiac disease eats a food with gluten in it, the immune system launches an attack against the small intestine which damages the lining of the intestine. Noticeable symptoms of celiac disease are diarrhea, abdominal (stomach) pain, weight loss, nutritional deficiencies, anemia, poor appetite, irregular periods, delayed growth, and delayed onset of puberty. Some teens will have almost no noticeable symptoms, but their health care provider may detect low bone density.

Gluten is toxic for someone with celiac disease. Following a gluten–free diet heals your small intestine, and usually stops your symptoms of celiac disease. Following a gluten–free diet may seem hard at first, but after a little while, you will see that there are tons of delicious options for you.

 

Things to keep in mind...

A gluten–free diet isn't always a healthy diet. Some people who follow a gluten–free diet may not get enough of certain nutrients, vitamins, and minerals in their diet such as fiber, iron and calcium. Also, some gluten–free products can be high in calories and sugar. If you must follow a gluten–free diet, it's best to meet with a nutritionist to develop a healthy, balanced meal plan and to identify if any vitamin or mineral supplements are necessary.

 

There are many hidden sources of gluten. Remember to check products such as toothpaste, mouthwash, lipstick/gloss, stamps/envelope, glues, supplements, vitamins, and both prescription and over the counter medications. These are frequently overlooked sources of gluten.
