Main types and causes of food intolerance

 Food intolerance is a disorder that affects a person's digestive system. Especially if you have 

food intolerances. You may have trouble digesting certain food groups. The main types of food 

intolerances are lactose intolerance and fructose intolerance. Gluten intolerance, salicylate 

intolerance, histamine intolerance, and food poisoning. Food intolerance affects the digestive 

system of our body. People with food intolerance have difficulty digesting food. Food intolerance 

is not a life-threatening problem. Food intolerances can cause discomfort and cause gas, diarrhea 

and constipation.

What is food sensitivity or intolerance?

Food sensitivity is another name for food intolerance. If you have a food intolerance. Your 

digestive system has trouble breaking down or digesting certain foods. This indicates that the 

intestines are irritated by certain foods. He can not break them. When you eat sensitive foods, 

you may experience gas, abdominal pain, and diarrhea.

What are the common types of food intolerance?

Common food intolerances include:

Lactose intolerance:

 Lactose is a type of sugar found in dairy products. Our digestive system breaks down food with 

the help of digestive enzymes. Lactase is an enzyme that helps digest lactose. People who do not 

have lactose intolerance and do not have enough lactase enzymes. So you are lactose intolerant or 

sensitive.

Gluten Intolerance:

 Gluten is a type of protein found in wheat, barley, rye, and other grains. Gluten sensitivity is 

different from gluten sensitivity. That's why gluten sensitivity is called non-gluten sensitivity. But, 

the symptoms of the two conditions can be similar. People with gluten sensitivity may experience 

fatigue, headaches, brain fog, and joint pain. If you experience any of these symptoms, check for 

food intolerance.

Fructose intolerance:

Fructose is a form of glucose found in some vegetables, fruits, and honey. This intolerance can 

occur in people who do not have the enzyme. This breaks down fructose. Although this 

intolerance is common. These food sensitivities can be inherited. People with fructose intolerance 

may experience bloating, gas, bloating, constipation, and diarrhea.

Salicylates Intolerance:

 Salicylates are found in some vegetables, fruits, spices, and herbs. It is also found in 

preservatives and artificial flavors. Like candy, gum, and toothpaste. Symptoms of this 

intolerance includes diarrhea, abdominal pain, nausea, fatigue, and shortness of breath.

Histamine intolerance:

Histamine is an organic chemical found in pineapples and bananas. It is also found in avocados, 

cheese, chocolate, and some red and white wines. People with histamine intolerance usually lack 

the enzyme dihydrogen oxidase. An enzyme that breaks down histamine.

Food poisoning: 

Some foods contain certain natural chemicals that are toxic to humans. Food poisoning is usually 

caused by bacteria, viruses, and parasites in food. Contamination occurs in eggs, meat, and dairy 

products. Symptoms can vary depending on the cause of the poisoning. But people with food 

poisoning often experience nausea, abdominal pain, vomiting, and headaches. Weakness, loss of 

appetite, low-grade fever, and diarrhea.

What is the cause of food intolerance?

The main causes of food intolerance or sensitivity are discussed below.

Genetics:

Many studies have shown that food allergies and food intolerances can be inherited. Lactose 

intolerance and fructose intolerance are types of food intolerance. Lactase enzyme deficiency is 

considered a hereditary disorder. People from Asia, Africa, and Native America are more likely 

to be lactose intolerant.

Deficiency of digestive enzymes:

Digestive enzymes are a type of protein that plays an integral role in digestion. As food is broken 

down, it is released through the digestive system. These enzymes help digest fats, 

proteins, and carbohydrates. Many types of food intolerances are caused by digestive enzyme 

deficiencies. For example, people with lactose intolerance do not have lactase enzymes. Without 

the enzyme lactase, your digestive system cannot digest lactose.

Non-gluten sensitivity:

 Many people are confused between gluten intolerance and celiac disease. The two conditions are 

different, but the symptoms can be similar. The exact cause of gluten intolerance is still unknown.

 

But, researchers describe the condition as an autoimmune, non-allergic condition. Consumption 

of gluten causes gastrointestinal symptoms.
