The Most Common Food Intolerances

Unlike some allergies, food intolerances aren't life-threatening. However, they can be very problematic for those affected. Food intolerances and sensitivities are extremely common and seem to be on the rise.

In fact, it’s estimated that up to 20% of the world’s population may have a food intolerance

Food intolerances and sensitivities can be hard to diagnose due to their wide range of symptoms.

The term “food hypersensitivity” refers to both food allergies and food intolerances

A food intolerance is not the same as a food allergy, although some of the symptoms may be similar. In fact, it can be difficult to tell food allergies and food intolerances apart, making it important to speak with your doctor if you suspect you might have an intolerance.

When you have a food intolerance, symptoms usually begin within a few hours of eating the food that you are intolerant to. Yet, symptoms can be delayed by up to 48 hours and last for hours or even days, making the offending food especially difficult to pinpoint, what’s more, if you frequently consume foods that you are intolerant to, it may be difficult to correlate symptoms to a specific food. While symptoms of food intolerances vary, they most often involve the digestive system, skin and respiratory system.

Common symptoms includ:







-Abdominal pain

-Runny nose


-Flushing of the skin

Food intolerances are commonly diagnosed by elimination diets specifically designed to narrow down offending foods or through other testing methods.

Elimination diets remove foods most commonly associated with intolerances for a period of time until symptoms subside. Foods are then reintroduced one at a time while monitoring for symptoms. This type of diet helps people identify which food or foods are causing symptoms.

Here are some of the most common food intolerances:








Food intolerances differ from allergies. Most do not trigger the immune system, and their symptoms are usually less severe.However, they can negatively impact your health and should be taken seriously. Many people are intolerant or hypersensitive to foods and additives like dairy products, caffeine and gluten.

Although food intolerances are usually less serious than food allergies, they can negatively affect your quality of life. This is why it's important to take steps to identify food intolerances in order to prevent unwanted symptoms and health issues.
