What is Gluten and how does it negatively affect the body?
Answers
GLUTEN:
Gluten is a protein naturally found in some grains including wheat, barley, rye, and spelt. It acts like a binder, holding food together and adding a “stretchy” quality—think of a pizza maker tossing and stretching out a ball of dough. Without gluten, the dough would rip easily.
WHEN IS IT HARMFUL?
It can cause serious side effects in certain individuals. Some people react differently to gluten, where the body senses it as a toxin, causing one’s immune cells to overreact and attack it. If an unknowingly sensitive person continues to eat gluten, this creates a kind of battle ground resulting in inflammation. The side effects can range from mild (fatigue, bloating, alternating constipation and diarrhea) to severe (unintentional weight loss, malnutrition, intestinal damage) as seen in the autoimmune disorder celiac disease. Estimates suggest that 1 in 133 Americans has celiac disease, or about 1% of the population, but about 83% of them are undiagnosed or misdiagnosed with other conditions. [8,9] Research shows that people with celiac disease also have a slightly higher risk of osteoporosis and anemia (due to malabsorption of calcium and iron, respectively); infertility; nerve disorders; and in rare cases cancer. [10] The good news is that removing gluten from the diet may reverse the damage. A gluten-free diet is the primary medical treatment for celiac disease. However, understanding and following a strict gluten-free diet can be challenging, possibly requiring the guidance of a registered dietitian to learn which foods contain gluten and to ensure that adequate nutrients are obtained from gluten-free alternatives. Other conditions that may require the reduction or elimination of gluten in the diet include:
Non-celiac gluten sensitivity, also referred to as gluten sensitive enteropathy (GSE) or gluten intolerance—An intolerance to gluten with similar symptoms as seen with celiac disease, but without the accompanying elevated levels of antibodies and intestinal damage. There is not a diagnostic test for GSE but is determined by persistent symptoms and a negative diagnostic celiac test.
Wheat allergy—An allergy to one or more of the proteins (albumin, gluten, gliadin, globulin) found in wheat, diagnosed with positive immunoglobulin E blood tests and a food challenge. Compare this with celiac disease, which is a single intolerance to gluten. Symptoms range from mild to severe and may include swelling or itching of the mouth or throat, hives, itchy eyes, shortness of breath, nausea, diarrhea, cramps, and anaphylaxis. People who test negative for this condition may still have gluten sensitivity. This condition is most often seen in children, which most outgrow by adulthood.
Dermatitis herpetiformis (DH)—A skin rash that results from eating gluten. It is an autoimmune response that exhibits itself as a persistent red itchy skin rash that may produce blisters and bumps. Although people with celiac disease may have DH, the reverse is not always true. Those with DH often do not have any digestive symptoms.
