Food intolerances occur when our body is unable to digest certain food items. This is due to the sensitivity of certain chemicals or when our body lacks certain digestive enzymes. Foods that normally trigger or cause food intolerances are:
- Fructose and caffeine
- Preservatives and food coloring
Now, let’s have a look at the various types and causes of food intolerances.
There are some foods that can naturally produce toxins in the human body and cause nausea, diarrhea, vomiting, and rashes.
Normally undercooked foods are the major cause as it allows bacteria to produce toxins. Therefore, people may confuse it with the food when it’s the cooking time that causes the production of toxins.
In the same way, food poisoning from canned food is again due to toxin production as a result of the improper way of storing and processing food. It can cause a severe allergic reaction, which can mimic food allergies.
These compounds are mainly present in the plant foods such as fruits, vegetables, spices, and herbs. Salicylates are the common compounds in preservatives and artificial food flavoring. Normally, people are able to tolerate salicylate while some may have reduced tolerance.
Some of the common symptoms of salicylate intolerance include:
- Stomach pain
Our digestive system has different enzymes to digest and break down food. If someone lacks a certain enzyme then, they are unable to digest those certain food items.
Milk has lactose in it. People who suffer from lactose intolerance, do not have lactase enzymes in their bodies. Hence, the body is unable to break down the lactose into smaller molecules. So, when lactose stays in the digestive system, it can cause diarrhea, gas, bloating and stomach ache.
Fructose is a sugar that is present in honey, fruits, and vegetables. Fructose intolerance is also due to the lack of an enzyme that breakdown the fructose. This is rare food intolerance. People who suffer from fructose intolerance show symptoms of diarrhea, cramps, bloating, fullness, and gas, after eating foods having fructose in them.
Gluten is a protein and it is majorly present in some cereals such as barley, wheat, and rye. A person who suffers from gluten intolerance, suffers from bloating, pain and nausea after eating certain food items.
There are some non-digestive symptoms that can be associated with a gluten intolerance such as:
- Joint Pain
- Brain fog
- Lack of general well-being
Gluten intolerance is also called “nonceliac gluten sensitivity”. The symptoms of gluten intolerance and celiac disease normally improve after removing gluten from the diet. However, when reintroduce, the symptoms return.
