Is a Gluten-Free Diet Healthy or Merely Trendy?

Gluten, a component of cereals, has gained significant popularity in recent years as a cause of many ailments. However, there are only a few cases where a gluten-free diet is justified, not just in celiac disease. Gluten is present in the seeds of wheat (gliadin), rye (hordein), and barley (secalin). It can also occur in oats, where it is often contaminated with other cereals. In Poland, certified oat products produced in Finland are available, which guarantee that they are gluten-free. Although gluten is not toxic, a gluten-free diet has become extremely popular. It has been attributed with weight loss and alleviation of various ailments. Is this true?

1. Gluten-free nutrition – when is it necessary?

Individuals suffering from celiac disease and gluten allergy should adhere to a gluten-free nutrition. The main difference between these two conditions lies in the mechanisms that cause the symptoms. In the case of gluten allergy, IgE antibodies are present, while in celiac disease, antibodies against endomysium and tissue transglutamine are present. Furthermore, in the case of celiac disease, intestinal villi atrophy is observed. It is important to note that the gluten-free nutrition should be adhered to for life by individuals with celiac disease. In the case of gluten allergy, the elimination of gluten does not have to be lifelong, but only for a certain period, after which attempts can be made to reintroduce gluten into the diet. There is also a controversial health unit that requires a specific diet – non-celiac gluten sensitivity.

2. Unrecognized hypersensitivity to gluten

Unrecognized hypersensitivity to gluten (UHG) is a commonly used and understood term, but so far there is no consensus among doctors and scientists as to its actual existence and possible diagnosis. UHG can be characterized by the occurrence of certain symptoms (abdominal pain, persistent bloating, sleep disorders, fatigue, diarrhea, headache, muscle pain, joint pain, skin changes, weight loss) several hours or days after ingestion of products containing gluten and their disappearance after the introduction of a gluten-free diet. The occurrence of UHG can only be considered after excluding celiac disease and gluten allergy. However, some scientists still doubt the existence of UHG, claiming that it is not a separate disease entity, but only a feature of the irritable bowel syndrome. If we want to follow a gluten-free diet, it is important to understand the strict rules of its application.

3. Gluten-free diet – Undesirable food products

In the case of a gluten-free diet, it is not permitted to consume products containing gluten or those contaminated with it. It is necessary to exclude all products produced using wheat, rye, barley and oats. In the case of oats, although it is a naturally gluten-free grain, it can be heavily contaminated with other cereals, so it is also not suitable for a gluten-free diet for sick people. We must give up wheat flour, rye flour, pasta and other products made from these flours, such as bread, oat flakes, barley, wheat bran, gluten-containing biscuits, barley, pearl, barley, barley coffee, certain types of alcohol (beer is produced from barley malt) and all products in which gluten is hidden in the form of food additives. Is it possible at all to have something to eat?

4. Gluten-free diet - allowable products

Naturally gluten-free cereals include maize, millet, proso and rice. A person with celiac disease can consume buckwheat, buckwheat flour, buckwheat pasta, oat bran, rice, rice flakes, cornmeal, potatoes, tapioca, amaranth, cassava, vegetables and fruits, meat, fish, oils, nuts and seeds. Contrary to the expectations of people with celiac disease, manufacturers of gluten-free products have emerged in the market. In stores, one can find gluten-free products marked with the international symbol of a crossed-out ear of corn, indicating that these products are safe for people with celiac disease because they contain no more than 20 mg of gluten per kilogram. However, despite the fact that these products are safe, their composition is not always obvious, so one must be careful.

5. Are we truly on a gluten-free diet – what to look out for?

There is a wide range of foods available on the market that do not naturally contain gluten but can contain it if it has been intentionally added due to its technological properties. Such products can pose a particular risk to people suffering from celiac disease. Here are some products that may be a source of gluten, although this is not always obvious: – baking powder, flavored sugar, creams for cakes, – wafers, – muesli, – processed meats (may contain starch), minced and packaged meats, – black pudding, pâté, – cutlets, – yogurts, buttermilk, cream, cheeses, milk products, puddings, – fruit and vegetable preserves, spice and herb blends, – chocolate and chocolate products, candies, chewing gum, ice cream, – mayonnaises, ketchups, and other ready-made sauces, – instant products, – medications. It is not possible to list all the potentially hazardous products, so it is important to know how to read labels. Fortunately, manufacturers are required to provide information on the packaging about the gluten content of a product. If starch is listed on the label in the ingredients list, you should pay attention to where it comes from. This information should also be indicated on the packaging (e.g., wheat/corn starch). The best diet is one that is based on natural products. Although there are gluten-free breads, pastas, and cookies on the market, they do not always meet the requirements of our palate. Gluten is a component of grains that gives the products made from them the right structure. The following sample meal plan shows that our menu can be based on naturally gluten-free products.
