Food Intolerance: Everything You Should Know About It

Food Intolerance
November 27, 2020

Typically when someone reacts to a particular food, that person has a food intolerance rather than a true allergy to that food. Despite their similar symptoms, a food allergy can be more critical.

What Does Food Intolerance Mean?

Some people experience difficulty digesting certain foods. This is known as food intolerance, non-allergic food hypersensitivity, or non-IgE mediated food hypersensitivity. Keep in mind that this is different from food allergy.

What are the Symptoms of Food Intolerance?

Some common symptoms of food intolerance are:

  • Stomach pain, bloating, gas, and diarrhea.
  • Itching and skin rashes

These symptoms usually surface a few hours after consuming the particular food.

What Causes Food Intolerance?

The leading causes of food intolerance include:

  • Absence of an enzyme
    To digest the food completely, our body requires many digestive enzymes. The absence of these enzymes can cause insufficient or improper digestion. For example, people who are lactose intolerant have insufficient lactase enzymes.

  • Chemical causes of food intolerance
    Some people are susceptible to certain chemicals in food, such as caffeine, and can develop food intolerance towards these chemicals.

  • Food poisoning
    Some foods contain naturally-occurring chemicals toxic to humans and are often found to cause nausea, vomiting, and diarrhea. For example, undercooked beans have aflatoxins that can cause severe digestive problems.

  • Natural occurrence of histamine in some foods
    Some foods, such as fish, when not stored correctly, can accumulate histamine. People sensitive to histamine may develop diarrhea, abdominal cramps, skin rashes, vomiting, and nausea when consuming such foods.

  • Salicylates present in foods
    Salicylate intolerant individuals should avoid foods containing high levels of salicylates, such as most plant-sourced foods, spices, herbs, tea, processed food, and flavor additives.

  • Food additives
    Out of the thousands of additives used in the food industry, certain additives like Nitrates, Sulfites, MSG, etc., are believed to cause problems.

Food allergy vs. Food Intolerance: What’s the Difference?

The main difference between a food allergy and food intolerance is that food allergy triggers the immune system while food intolerance does not. Therefore, a food allergy can affect your whole body and not only your stomach. Also, symptoms of food intolerance tend to take much longer to appear than symptoms of allergies.
