• A gluten-free diet is an eating pattern that completely eliminates gluten, a protein found in certain grains such as wheat, rye, and barley. This type of diet was originally developed for people with celiac disease, an autoimmune disorder in which gluten causes intestinal damage. However, over time, the gluten-free diet has also gained popularity among people without the disease, in hopes of improving well-being, losing weight, or addressing other health issues. It is important to note that this diet requires careful food selection, as many common foods contain hidden sources of gluten.
• Who can benefit from this diet?
• Gluten is present in a variety of foods, primarily grains. The main sources are wheat, barley, and rye. Therefore, products made from the flour of these grains, such as bread, pasta, cookies, and beer, contain gluten. It is also worth remembering that gluten can be found in processed foods, such as sauces, seasonings, and some types of meat products, where it is used as a thickener or stabilizer. Therefore, it is important for people with gluten intolerance to carefully read the ingredients of foods to avoid consuming it.
• Indeed, this is true: it is even present in beer.
• On a gluten-free diet, you can include a variety of foods and dishes that do not contain gluten. The main categories are:

  1. **Grains**: Rice, corn, buckwheat, quinoa, millet, and sorghum are excellent alternatives to wheat and other gluten-containing grains.

  2. **Vegetables and Fruits**: All fresh vegetables and fruits are safe to eat. Not only are they gluten-free, but they are also an important source of vitamins and minerals.

  3. **Meat and Fish**: Lean meats, poultry, fish, and seafood are also naturally gluten-free. It is important to avoid processed meats, as they may contain added gluten.

  4. **Dairy**: Milk, yogurt, cheese, and cottage cheese are generally safe, but you should read labels carefully for added ingredients.

  5. **Eggs**: Eggs are an ideal source of protein that is gluten-free.

  6. **Nuts and Seeds**: All types of nuts and seeds are safe to include in your diet. They are healthy and nutritious.

  7. **Legumes**: Lentils, beans, and peas are excellent sources of protein and fiber and are gluten-free.

  8. **Gluten-Free Alternatives**: There are many wheat flour substitutes on the market, such as almond, coconut, rice, and potato flours, which can be used in baking and cooking.

  9. **Beverages**: Water, tea, coffee, and most juices are gluten-free. However, beware of drinks with additives and flavorings.

  When following a gluten-free diet, it is important to pay attention to food labels and choose natural, unprocessed options to avoid accidentally introducing gluten into your diet.

• There are several types of grains that are gluten-free. These include rice, corn, buckwheat, millet, and sorghum. These foods can serve as excellent alternatives for people with gluten intolerance or celiac disease.
• A sample menu for a gluten-free diet can include a variety of gluten-free dishes. A morning meal could start with an omelet with vegetables and fresh herbs, along with a serving of fruit, such as apples or pears. Nuts or plain yogurt are good snacks.

  For lunch, you could prepare a salad with chicken, avocado, and olive oil, complemented by buckwheat or rice. Vegetable and bean soup is an alternative option.

  Dinner could consist of baked fish with a side of green beans and mashed potatoes seasoned with olive oil and spices. For dessert, you can choose gluten-free sweets, such as chocolate mousse or fruit salad.

  Throughout the day, you can also enjoy a variety of beverages, including herbal teas and freshly squeezed juices, while avoiding beverages containing gluten.

• A gluten-free diet, while necessary for people with celiac disease or gluten intolerance, is not always advisable for those who do not suffer from these conditions. It can lead to a number of negative consequences. Firstly, eliminating gluten from the diet can reduce the intake of important nutrients such as fiber, B vitamins, and iron, which are found in whole grains.

  Furthermore, many gluten-free alternatives are often processed and contain more sugar and fat to improve taste. This can lead to increased calorie intake and, as a result, unwanted weight gain. It's also worth considering that not all gluten-free products are healthy—some may contain artificial additives and preservatives.

  It's important to understand that drastic changes in diet without medical indications can cause imbalances in the body. Therefore, before deciding to switch to a gluten-free diet, it is recommended to consult a doctor or nutritionist.

• To find gluten-free products, you should pay attention to several key aspects. First, study the labels on packages, where manufacturers are required to indicate the presence of gluten. You should look not only for gluten itself, but also its derivatives, which can be hidden under different names.

  Second, choose natural products such as fruits, vegetables, meat, and fish, as they usually do not contain gluten. It is also useful to turn to specialty stores that offer products for people with gluten intolerance.

  Also, it is worth paying attention to product certification. Many brands produce products with the "gluten-free" label, which makes the choice much easier. You can also use mobile apps and online resources to help you find such products.

  So, carefully reading packages, choosing natural products, and using specialized resources will help you easily find gluten-free options.

Definition of a Gluten-Free Diet: What Is It?

A gluten-free diet involves the complete removal of gluten—a protein compound found in products made from wheat, rye, barley, and their crossbreds.

Gluten makes up approximately 80% of the total protein content in the seeds of these grains. However, in each individual cereal, the gluten fraction includes various protein components:

• Wheat contains gliadins.
• Rye contains secalins;
• Barley contains hordenines [2].

Gluten, which is found in wheat, is a combination of two types of proteins: gliadin and glutenin.

In Russian, the term "gluten" refers to gluten, which is part of cereals. This name is no coincidence: the Latin word "gluten" translates as "glue". This substance received this name due to its ability to give wheat products, such as pasta and bread, a viscous and elastic texture.

Symptoms and conditions that require a gluten-free diet

Many people choose to give up gluten-containing products due to persistent digestive problems such as diarrhea, flatulence, and abdominal discomfort. A gluten-free diet can significantly reduce these symptoms or even completely eliminate them if the underlying cause of the problems is:

• Wheat allergy is an immune response to the protein components of this crop, and it is most often seen in children.
• Celiac disease is a disease that develops as a result of the presence of antibodies to gliadin proteins in the intestine. An autoimmune response damages the walls of the small intestine. In the most severe cases, this condition can lead to blood problems and osteoporosis.
• Hypersensitivity to gluten causes symptoms that may resemble allergic reactions or signs of celiac disease. However, a medical examination does not reveal any immune or autoimmune disorders in the patient. It is worth noting that this condition is much more common than celiac disease itself.

The main difference between celiac disease and other diseases lies in the changes that occur in the villi of the small intestine. In the case of celiac disease, these villi thin and lose their functionality, while in other reactions to gluten, they remain intact.

In recent years, there has been a growing belief that a gluten-free diet can have a positive effect on children with autism spectrum disorder. Parents note that their children become more sociable and calm when this protein is excluded from their diet. However, scientific research has not yet confirmed the effectiveness of such a diet for children with autism spectrum disorders.

Sources of Gluten in Everyday Foods

In order to properly develop a menu, it is important to be aware of all sources of gluten, both those that clearly contain it and those where it may be hidden.

The most obvious sources of gluten include foods such as bread, pastries, pasta, and cereals made from wheat, semolina, barley, pearl barley, bulgur, and couscous. However, this is only a small part of the whole variety of products containing gluten.

A gluten-free diet will not be effective if foods containing hidden gluten remain in the diet.

• Processed foods include cooked sausages, frankfurters, semi-finished products from finely chopped meat and fish, as well as potato and corn chips.
• Canned goods cover a wide range of products, including canned meat, fish, vegetables and fruits.
• Sauces are mayonnaise, ketchup and mustard.
• Condiments are mixtures of various dry ingredients, including spices, concentrated soup powders and bouillon cubes.
• Semi-finished products include soups and mashed potatoes, which can be prepared quickly, as well as dumplings, vareniki and breaded products of meat, fish and vegetables.
• Breakfasts that can be :Quick to prepare, they are corn flakes enriched with barley malt.
• Products that imitate seafood, such as "crab sticks" and "crab meat";
• Among sweets, one can distinguish such delicacies as caramel, soy-based and chocolate candies with a variety of fillings, oriental desserts, as well as jam produced in industrial plants.

Food additives, such as preservatives and stabilizers, may contain gluten [9]. If you come across E-codes in the range E1400-E1451 (related to starches) or E150, it is worth clarifying their source, as it can be wheat, barley or rye. In addition, some types of instant coffee, including espresso capsules, may contain gluten-based additives.

Food additives, designated by the letter E, are substances that are added to food products in order to improve their properties. These additives can perform a variety of functions, from preserving and extending shelf life to improving flavor, color, and texture. The numbering of additives, beginning with the letter E, allows for easy identification in products and monitoring the safety of their use. Each additive undergoes rigorous testing and safety assessment before being approved for use in the food industry.

Does beer contain gluten: myth or reality?

The bulk of beer is made from malt, which is grain that has been germinated and dried. Malt is typically derived from cereals containing gluten, with barley being the most common. According to an Australian study, gluten levels in barley beer can range from 19 to 45 ppm. At the same time, wheat-based beer contains significantly more gluten, reaching an average of 40,800 parts per million.

Variety of Foods on a Gluten-Free Diet: Which Products and Dishes Are Suitable

The range of permitted foods includes a variety of both tasty and nutritious options. This list includes both animal and plant products.

The following are allowed on a gluten-free diet without any restrictions:

• fruits and vegetables;
• beans and legumes;
• meat;
• vegetable oils
• eggs;
• milk;
• fish;
• nuts;
• gluten-free cereals [12].

Six types of gluten-free cereals

Cereals that can be consumed as part of a gluten-free diet are often called "minor" or "small" [13]. Let's take a closer look at their main types.

There are over 40,000 different varieties of rice, all of which are gluten-free. This category includes white, brown, red, black, and wild rice. White rice is produced by milling and polishing the grains, while brown rice retains its outer husk, which is rich in fiber and nutrients. If, in addition to a gluten-free diet, you need to control your blood sugar levels, you should give preference to brown rice, since its glycemic index is low.

For many years, oats were considered one of the forbidden foods for People with celiac disease. Although oats themselves are gluten-free, they are often contaminated when in contact with grains containing this protein. This contamination can occur during harvesting, transportation, storage, or processing, and is called cross-contamination. However, manufacturers are currently actively working to implement technologies that will ensure the safety of oats and eliminate the risk of accidental contamination with gluten.

Oats are a source of vital nutrients that people on a gluten-free diet sometimes lack, such as B vitamins. Buckwheat flour can also be successfully used instead of wheat flour to thicken soups, sauces, and casseroles.

Teff is a grassy plant native to Ethiopia, and its seeds are the smallest of all grains in the world. For comparison, 100-150 teff seeds are equivalent in size to one grain of wheat. Teff has a distinctive, mild, nutty flavor, reminiscent of molasses, making it a flour suitable for baking.

A gluten-free diet allows for corn tortillas and popcorn. However, it's important to remember that corn is high in calories.

Quinoa has been used as a food in South America for thousands of years and was a staple of the Incas. It is recommended to soak or rinse this grain to remove saponins, which can give it a slightly bitter taste. However, researchers from China recently discovered that quinoa's unique flavor is linked to its beneficial substances—polyphenols.

Half a cup of amaranth can be a valuable source of magnesium, vitamin B6, and selenium. In addition, this cereal contains lysine, an amino acid that is absent in many other grains.

Preliminary meal plan for a gluten-free diet

As a result, 1,478 calories were consumed per day, as well as 87 grams of protein and 39 grams fiber.

Negative effects of a gluten-free diet

Medical and nutrition experts do not recommend following a gluten-free diet unless there is a medical reason for it. Consuming exclusively gluten-free products can have a negative effect for several reasons.

• This diet is low in fiber. It is recommended that an adult consume 25 to 38 grams of fiber daily, but many people do not achieve even this minimum level. It should be noted that a gluten-free diet makes the task of obtaining the required amount of fiber more difficult, since a significant portion of this substance comes from whole grain bread, which contains gluten.
• In addition, they may experience nutrient deficiencies. People who follow a gluten-free diet often don't get enough B vitamins, including thiamin, riboflavin, niacin, and folate.
• This can pose a risk to the cardiovascular system. People without celiac disease have an increased risk of heart and vascular disease if they avoid gluten. Experts explain this by the fact that such a diet often leads to the exclusion of whole grains, and therefore to insufficient fiber intake.

“It should be noted that a gluten-free diet does not promote weight loss. Moreover, many gluten-free products sometimes contain more carbohydrates than their gluten-containing counterparts. "Scientific studies do not provide evidence that eliminating gluten will lead to weight loss," says Dr. Alessio Fasano, who directs the Celiac Disease Research Center and the Division of Pediatric Gastroenterology and Nutrition.

Fasano also emphasizes that weight loss in people on a gluten-free diet is most likely due to improved overall nutrition, rather than solely to eliminating gluten from the diet.

Finding Gluten-Free Products

The U.S. Food and Drug Administration emphasizes that a product must carry the "gluten-free" label on its packaging if it meets certain criteria.

• does not contain gluten in its original state;
• has been processed to eliminate gluten;
• has successfully completed certification and testing for cross-contamination gluten;
• may have a gluten content below 20 parts per million.

Gluten-free products are usually marked with the crossed-out grain symbol. The packaging may also say "gluten free."

20 ppm is the minimum level that can be detected in foods using high-quality scientific analytical tools. For most people with celiac disease, this concentration is considered safe, so it has become the accepted standard in the United States, Europe, Russia, and China.

A Guide to Starting a Gluten-Free Diet

• Pay attention to food labels—unnoticeable gluten can often be found in them.
• Storage gluten-containing and gluten-free foods separately. Using different utensils and equipment is ideal, as this helps minimize the chance of cross-contamination.
• Be extremely careful when eating at restaurants. Even if your food is gluten-free, it may have been cooked on the same board or fried with gluten-containing ingredients. Be sure to inform your server if you have celiac disease or a sensitivity to this substance.
• When choosing flour for baking, give preference to options labeled "gluten-free." This applies not only to various types of bread, but also to waffle mixes, muffins, pizza crusts, and many other products that do not contain gluten.
• Be careful of non-food sources of gluten. This protein is found not only in food products. Because of its "sticky" properties, gluten is added to various processed products, as well as to medications, cosmetics, and vitamin complexes.

First of all, it is important to make sure that a gluten-free diet is truly recommended for you - laboratory tests can help with this. If you tolerate gluten normally, there is no need to give it up. Scientific evidence does not confirm that a gluten-free diet is beneficial for healthy people.
