What is gluten and why are people avoiding it?
Gluten is a term for proteins found in certain grains like wheat, barley, rye and triticale (a wheatrye hybrid). When mixed with liquid and manipulated, the proteins form an elastic substance that gives structure to flour mixtures such as bread.
When a person with celiac disease eats gluten, his/her immune system responds by attacking the lining of the small intestine. The small, fingerlike growths in the intestine, called villi, are damaged in the process (see image on the right) and are not able to absorb the important nutrients needed for health. This increases the risk for nutrient deficiency diseases like bone disease and anemia.
How many people suffer from celiac disease?
It is estimated that around 1 percent of the US population has celiac disease. Another 5 to 10 percent of the population may have some degree of gluten intolerance or sensitivity. Nonceliac gluten sensitivity does not result in damage to the digestive tract, but it can cause a range of uncomfortable symptoms similar to those of celiac disease.
What are the symptoms of celiac disease?
Symptoms of celiac disease include: stomach pain, gas, diarrhea, extreme tiredness, change in mood, slowed growth, itchy skin rash with blisters, and weight loss.
The only treatment for celiac disease is a gluten free diet. Avoiding gluten will allow the small intestine to heal. Eating foods that contain gluten will continue to harm the small intestine.
Will a gluten-free diet help you lose weight?
For people who do not have celiac disease, gluten intolerance or gluten sensitivity, a gluten-free diet doesn’t provide any health benefit. The whole grains that contain gluten are a good source of fiber, vitamins and minerals. People following gluten free diets may not get enough essential nutrients and may need to take supplements.
People who do not have celiac disease but follow a gluten free diet may lose weight and feel better because they have cut out foods made with refined grains like desserts, snack foods and other processed foods.
