What is gluten?
Gluten is a substance that is part of the protein of wheat, barley, rye and most other cereal crops. The more gluten is contained in flour, the easier it is to make a dough that turns into airy pastries. The content of gluten in the wheat protein of higher grades is up to 30%.
Because gluten is essentially glue-based( which is why it is called "gluten"), it is widely used to impart a thick texture to sauces and other products. Gluten also glues together the contents of the stomach, provoking inflammation and the development of food allergies in some people. Is the gluten-free diet leading to rapid weight loss? What can you eat on this diet? What is harmful gluten?
It is important to separate the harm of products with gluten and the harm of gluten itself. Since gluten is the main component of wheat flour, it is found in large quantities in bread and in all baking. This kind of food causes a quick set of excess weight, whereas refusal of it is useful for losing weight.
On the other hand, the immunity of some people perceives gluten as an allergen, causing the body to "fight" with it. Since gluten comes with food, the stomach suffers first. Violated bowel function, lower levels of absorption of carbohydrates, fats, vitamins and minerals.
Celiac disease - allergy to gluten
A disease called celiac disease, which is an allergy to gluten, occurs in 1% of the population - on average, in one person from 100-150( 2).In such people, the use of even minimal doses of gluten( 0.1 g) can cause a serious food allergy with unpleasant symptoms.
It is believed that gluten intolerance is a genetic disease similar to lactose intolerance. If your parents or relatives have celiac disease, you are probably also susceptible to it. In this case, you will have to adhere to a strict gluten-free diet all your life.
Symptoms of allergy to gluten
Most of the symptoms of gluten intolerance are disorders of the digestive system - chronic bloating, persistent diarrhea and other stomach disorders. In many cases, the stool becomes pale and frothy, while having a sharp unpleasant odor( 2).
Secondary symptoms of allergy to gluten are headaches, hair loss, decreased immunity, worsening metabolism. Given the mild severity of symptoms, diagnosis of celiac disease is most often difficult, and many patients do not even guess about their illness.
A way to detect gluten intolerance
A simple home-based method of detecting gluten intolerance is to exclude from the ration of bread and any other gluten-containing foods for several days, as well as a close assessment of your well-being. The subsequent return of these products to food will be indicative.
The intestinal microflora will take about 10-14 days to recover. If returning to a normal diet containing gluten will provoke any digestive problems, then you should consult a doctor to make a full medical test for celiac disease.
