Is Gluten-Free the Way to Be?
1 A lot of people suffer from celiac disease and find it hard to control the symptoms. Most of these people, however, are not doing so because of medical necessity. Gluten is not 2 an absolutely essential nutrient, so no one is harmed by following a gluten-free diet. In fact, it may be a good idea to try going gluten-free, as it may reveal some health issues that might have gone undiagnosed.
Studies indicate that about 1 percent of Americans have celiac disease, meaning that eating even 3 standard amounts of gluten will make them ill. Gluten is a protein composite found in 4 wheat, barley, rye and a few other related grains, and it contains amino acid sequences that trigger immune responses in people with celiac disease. Tissues in the small intestine react as if the protein belonged to a harmful virus or 5 bacteria. They become inflamed. This inflammation prevents nutrients from being properly absorbed in the small intestine, resulting in a variety of serious conditions. It also causes gas and bloating, cramps, and diarrhea or constipation.
 Although a small percentage of Americans have celiac disease, a much higher percentage report that they try to eat a gluten-free diet or are trying to eat less gluten.  6 According to one survey, some 20 percent of people are trying to avoid or cut back on gluten.  Why are so many people following, or trying to follow, a gluten-free diet if they have not been diagnosed with celiac disease?  In some cases, they might feel better on the diet because they have celiac disease but have never been diagnosed.  People who suspect they have celiac disease because a gluten-free diet made them feel better still need to get diagnosed, but they might never have suspected they had the disease if going gluten-free had not become so popular.7
A lot of people who have been found not to have celiac disease still feel better when they follow a gluten-free diet. Researchers have carefully tested groups of these people, giving them a diet that omitted gluten and then adding gluten back into their diet in 8 pill form, some felt no difference when gluten was added back into their diets. Some, 9 moreover, were affected by gluten, which suggests that there might be other health conditions related to gluten besides celiac disease. These conditions affect only a small percentage of people, so the conditions might not have been noticed and studied if gluten-free diets had not become so popular.
Although it will not necessarily improve the health of everyone who tries it, a gluten-free diet does no harm and definitely 10 benefiting more people than doctors and researchers originally 11 .
