What is Food Intolerance?

Whatever we eat, our body digests it with the help of various digestive juices or enzymes. The problem of food intolerance occurs when a person’s body is unable to digest certain foods, that is, the body is not able to make enough enzymes to digest that substance. Many people do not digest cow’s milk. Cow’s milk contains lactose. The lactase enzyme is needed in the body to digest it. If the body does not have enough lactase, then lactose cannot be digested. In such a situation, if a person consumes cow’s milk, then the symptoms of food intolerance are seen in the body.

Food intolerance can also occur due to a deficiency of an enzyme called alcohol dehydrogenase. People who lack this enzyme can be affected by consuming even small amounts of alcohol. Many people experience adverse reactions after consuming foods containing chemical preservatives. Chemicals like sulfides, salicylates, monosodium glutamate, ajinomoto salt, caffeine, aspartame and tartrazine in the market can cause food intolerance.

Due to the lack of specific enzymes in the body, what we eat is not digested, due to which toxic byproducts start forming in the body. Apart from these, histamine is also formed due to which swelling starts appearing in the body. These symptoms are similar to allergies but it is not caused by allergies but due to food intolerance, hence it is also called spurious allergic reaction.

Babies have high levels of lactose at birth, so the problem of lactose intolerance begins only after the age of 2 years when both the level and production of lactase in the body start to decline. Many times it also happens that its symptoms start appearing in people after many years. If there is a temporary deficiency of lactase in the body, it can lead to gastroenteritis (vomiting and laxatives). It is especially seen more in children.

What are the symptoms of Food Intolerance?

Its severity depends on two things, the amount of food consumed and the amount of enzymes being produced in the body.

How to Diagnose Food Intolerance?

To detect lactose intolerance, on the advice of the doctor, tests like lactose intolerance test, hydrogen breath test, stool acidity test, etc. can be done.

How to cure Food Intolerance?

Young children or infants with lactose intolerance can be given soy milk or hypo-allergenic milled formula instead of cow’s milk. Adults can tolerate small amounts of harmful foods.

It is very important to pay attention to the fact that if you are stopping taking something, then instead of it, you must include a suitable substitute diet in your diet so that there is no shortage of nutrients in the body.
