DO YOU HAVE A FOOD ALLERGY OR FOOD INTOLERANCE?

What is food intolerance?

Food intolerance, also known as non-IgE mediated food hypersensitivity or non-allergic food hypersensitivity, refers to difficulty in digesting certain foods. It is important to note that food intolerance is different from food allergy.

Food allergies trigger the immune system, while food intolerance does not. Some people suffer digestive problems after eating certain foods, even though their immune system has not reacted – there is no histamine response.

Foods most commonly associated with food intolerance include dairy products, grains that contain gluten, and foods that cause intestinal gas buildup, such as beans and cabbage.

FOOD ALLERGy vs. food INTOLERANCE

Physical reactions to certain foods are common, but most are caused by a food intolerance rather than a food allergy. A food intolerance can cause some of the same signs and symptoms as a food allergy, so people often confuse the two.

A true food allergy causes an immune system reaction that affects numerous organs in the body. It can cause a range of symptoms. In some cases, an allergic food reaction can be severe or life-threatening. In contrast, food intolerance symptoms are generally less serious and often limited to digestive problems.

If you have a reaction after eating a particular food, see your doctor to determine whether you have a food intolerance or a food allergy.

What are the most Common Food Intolerances

As individuals, our reactions to foods and drinks vary a great deal. An ingredient which may cause problems for one person could be completely acceptable for another. At yorktest, we like to refer to this as our ‘food fingerprint’.

Interestingly, our recent customer survey date shows that 64% of yorktest customers have between 2 and 8 food reactions.

Understanding your own personal food and drink intolerances, and the effects they could have on your health and wellbeing, is important to ensure you make the best possible choices for your diet.

The foods that tend to cause intolerance reactions in sensitive people include:

dairy products, including milk, cheese and yoghurt
chocolate
eggs, particularly egg white
flavour enhancers such as MSG (monosodium glutamate)
food additives
strawberries, citrus fruits and tomatoes
wine, particularly red wine
histamine and other amines in some foods.

Symptoms of food allergy and intolerance

It can be difficult to tell the difference between the symptoms of food allergy and food intolerance. Usually, symptoms caused by food allergy develop very soon after consuming the food. While symptoms caused by food intolerance can be immediate, they may also take 12 to 24 hours to develop.

Food intolerance reactions are usually related to the amount of the food consumed. They may not occur until a certain amount (threshold level) of the food is eaten, but this amount varies for each person.

The symptoms of food allergy and intolerance can also be caused by other conditions, so it is important to see your doctor for a medical diagnosis.

Symptoms of food intolerance can include:
