What is the difference between food allergy and food intolerance?

Frequently Asked Questions
Many people think the terms food allergy and food intolerance mean the same thing; however, they do not. A "food intolerance" is an adverse food-induced reaction that does not involve the immune system. Lactose intolerance is one example of a food intolerance. A person with lactose intolerance lacks an enzyme that is needed to digest milk sugar. When the person eats milk products, symptoms such as gas, bloating, and abdominal pain may occur.

Frequently Asked Questions
Food allergy involves a reaction of the body's immune system; food intolerance does not. Food intolerance stems from problems with digestion or metabolism-the way the body breaks down food-usually because of an enzyme deficiency. Food intolerance rarely causes life-threatening reactions, as is possible with food allergy. A common symptom of food allergy is hives on the skin.

What is the difference between Food Intolerance and Food Allergy?

Allergic Diseases, S.C.
Food intolerance is much more common than food allergy and occurs when the body is unable to digest a particular food. This causes symptoms of discomfort including cramping abdominal pain, diarrhea, belching, bloating, and gas. These symptoms may be quite uncomfortable, however, they usually do not pose a great danger to the person. One common food intolerance is lactose intolerance. People with this problem lack enzymes in the stomach needed to digest milk properly.

What is the difference between intolerance and an allergy?

Alpro soya - Frequently Asked Questions
allergy is a type of food intolerance but there are other types of food intolerance which do not involve a reaction from the immune system. The most common food intolerance, linked to the absence or poor levels of the lactase enzyme, is lactose intolerance. This enzyme is used to digest lactose, the sugar found in dairy milk. If not enough lactase is produced by the body some of the lactose passes through the gut undigested and causes symptoms such as diarrhoea.

A food intolerance occurs when your digestive system cannot handle a certain type of food, normally due to a missing enzyme. An intolerance may present some of the same gastrointestinal symptoms as a food allergy, such as abdominal pain and diarrhea. A food allergy, however, involves an allergic response from the body's immune system.

Food Allergy Survival Guide: FAQ
Food allergy is the reaction of the body's immune system to a food or food ingredient that it recognizes as "foreign." Food intolerance is an adverse reaction to a food, food ingredient, or additive that does not involve the immune system. It typically involves the digestive system. Plausible theories for the cause of these changes span the spectrum from too much cleanliness in our lives, on the one hand, to the lack of it (in air quality, for example).

What's the difference between milk allergy and lactose intolerance?

MooMilk -- FAQ
Milk allergies are an abnormal response by the body to milk protein. Lactose intolerance is the body's inability to digest lactose, the sugar in milk. Allergies to milk are rare, while lactose intolerance is not. A food allergy is an abnormal response of the body's immune system to ordinarily harmless foods or ingredients -- in this case, milk protein. An estimated 1-3% of infants and young children have milk allergy, but usually outgrow it by two or three years of age.

Frequently Asked Questions
A food allergy is an immune system response to a food that the body mistakenly believes is harmful. Once the immune system decides that a particular food is harmful, it creates specific antibodies to it. The next time the individual eats that food, the immune system releases massive amounts of chemicals, including histamine, in order to protect the body.

What is a food intolerance?

Wimpy
Food intolerance is much more common than food allergy, and is the less serious of the two conditions. Food intolerance is an exaggerated or abnormal physical reaction to a food or food additive (such as an artificial colourings or preservatives) that does not involve an immune reaction. A chemical deficiency in the body is usually the cause of the problem. It has nothing to do with food allergy because the reaction does not involve the body's immune system.
