Food intolerance What is this
What is food intolerance and how does it differ from a food allergy?
If a food allergy depends on disruption of the immune system of the body,food intolerancedepends on the diseases of the digestive system, which cause a reaction to the product that has been consumed.
A food allergy gives an instant reaction to the food consumed, regardless of how much of it has been eaten.Food intolerancedepends on the quantity of the food eaten and manifests itself some time after the consumption.
Food intoleranceis caused by inherent and acquired (due to digestive disorders) reasons. For example, intolerance towards the consumption of a cow’s milk in a child occurs because of lactase deficiency. It may develop in adults as well due to the lack of ferment, which converts lactose. This occurs with metabolic disturbances.
The lack of ferments for food digestion causes a malfunction in the absorption of the main food elements proteins, fats and carbohydrates. That’s why a person with an insufficient set of ferments feels discomfort after meals.
Often, toxic reactions develop withfood intolerance. They may occur due to toxic admixtures or contamination in food products. Toxic admixtures may form in the process of cooking food. For example, mold, affecting food products: cheeses and various grains contain a poisonous substance aflatoxin. The reaction of the organism to such a toxin is a digestive system disorder. Certain toxins are found in mushrooms, fruits, and berries. Various food additives may cause toxic reactions.
Why does food intolerance occur?
If the digestive system is in normal, extra vulnerability towards food products doesn’t occur. With normal digestion, food decomposition leads to t particles which do not cause the extra vulnerability of the body towards separate food components. The intestine walls do not permit undigested particles which cause reactions of food intolerance. If a person has a digestive system disorder, the walls of the intestine are permeable. Undigested particles are absorbed and cause the reaction of the body to thefood intoleranceof these substances.
Food intolerancedevelops gradually. An inappropriate eating regime, low stomach acidity, and other diseases of the digestive system influence its development. Food intolerance occurs gradually to some kinds of food that are constantly consumed. First, food intolerance symptoms appear slightly. Little by little the reaction increases and a severe attack may occur. The process of food intolerance spreads. The foods that were safe before become dangerous for consumption.
The role of histamine in food intolerance
The production of the substance called histamine plays a big role in food intolerance. This is a hormone that regulates many processes in the body and causes painful reactions under stressful conditions.
Products with large concentration of histamine cause the food intolerance.
Usually, these are fermented foods. For example, sour cabbage, some kinds of cheese, pork liver, fish, and seafood. Some vegetables, like spinach and tomatoes also possess this special feature.
Food intoleranceis caused by some food additives, which may be put on or into cooked products to improve the taste of the product. These may be preservatives, food coloring agents, aromatisers, taste additives, or products containing sulfites.
If you exclude the product causing food intolerance for a few months and then gradually bring it back into your ration, the reaction may disappear. Symptoms may appear if you consume it from time to time in small quantities.
What is celiac disease?
There is a disease of the small intestine, called celiac disease. This is a hereditary disease in which some foods damage the fibers covering the walls of the small intestine. Products such as oats, wheat, rye, and barley contain the gluten substance. Gluten causesfood intolerancein patients suffering from celiac disease. Those who have celiac disease must choose gluten free products. Celiac disease may occur not only in infantile age, but adults and elderly people may also get sick with it. Stress, viral infections, and various poisons contribute to the disorder - celiac disease. The symptoms of celiac disease are difficult to diagnose because they may include stomach discomfort, pain in the bones, weight loss, iron-deficient anemia, etc.
Gluten free products relieve the symptoms of celiac disease
If a person consumes gluten free products, his or her well-being improves. Such a patient is prescribed with a permanent diet of the consumption of gluten free products.
Food intoleranceincreases a digestive system disorder. If celiac disease is not treated, the symptoms of a severe digestive system disorder progress and the disease may develop into cancer. That’s why it’s so important to diagnose food intolerance early and consume gluten free products, which decrease the effects of the celiac disease. Following a diet with gluten free products for a long time relieves the symptoms of celiac disease completely, and restores the walls of the small intestine.
