Major Causes and types of certain food intolerances

Food intolerance is a vast topic though. Here we will discuss various types of food intolerance and their causes as knowing the specific type and its causes may help in intolerance testing.

Lactose intolerance 

It is a condition in a person is unable to digest. Digestive enzymes help the body break down meals. Particular meals may be more difficult to digest if a person lacks certain enzymes.

Lactose is a type of sugar found in milk. Lactose intolerance is caused by a lack of lactase, an enzyme that breaks down lactose into smaller molecules that the body can absorb readily through the intestine.

Lactose can produce spasms, stomachaches, bloating, diarrhea, and gas if it stays in the digestive tract.

Fructose intolerance

Fructose is a type of sugar that can be found in fruits, vegetables, and honey. Although rare, fructose intolerance can also be caused by a deficiency of an enzyme. Hereditary fructose intolerance is the term for this condition.

Fructose malabsorption is far more prevalent, and it occurs when the body lacks a protein that helps it to absorb sugar from the intestine.

Food fructose ferments in the intestines of these people, causing gas, fullness, bloating, cramps, and diarrhea.

Gluten intolerance 

It is a condition in which a person is unable to digest gluten found in wheat and some other grains.

Gluten is a protein found in wheat, barley, and rye, among other cereals. After ingesting gluten-containing meals, a person with gluten sensitivity may experience pain, bloating, or nausea.

Nondigestive symptoms of gluten intolerance include brain fog, headaches, joint pain, exhaustion, sadness, worry, a general feeling of unwell-being.

Gluten intolerance is distinct from celiac disease, which is an autoimmune reaction to gluten, and wheat allergy, which is a reaction to wheat. The symptoms of many illnesses, however, may be identical.

Nonceliac gluten intolerance

It is another name for gluten intolerance. When a person eliminates gluten from their diet, their symptoms of celiac disease and gluten intolerance usually improve, but they return when they reintroduce it.

Intolerance to salicylates

Salicylates are natural chemicals found in a variety of plant foods such as fruits, vegetables, herbs, and spices. Artificial flavorings and preservatives, such as those found in toothpaste, chewing gum, and candies, are likewise high in them.

The majority of people can handle modest levels of salicylates in their diet, however certain individuals have a lower tolerance.

The most common symptoms include rashes, stomach pain, diarrhea, exhaustion, runny nose, wheezing.

Intolerance to food additives

Food manufacturers frequently utilize additives to improve flavor, make foods more appealing, and extend their shelf life. Antioxidants, artificial colorings, artificial flavorings, emulsifiers, taste enhancers, preservatives, and sweeteners are all examples of food additives.

Some people may have negative reactions to the following dietary additives:

  • Nitrates – These preservatives are frequently found in processed meats, and intolerance symptoms include headaches and hives.
  • Monosodium glutamate (MSG) – Those with an intolerance to this taste enhancer may have headaches, chest tightness, nausea, and diarrhea.
  • Sulfites – Wine, dried fruits, raw shrimp, and several jams and jellies are common sources of these preservatives. An intolerance can cause chest tightness, hives, diarrhea, and anaphylaxis in certain people.
