Main differences between food allergies and food intolerances
We often talk about food allergies and food intolerances indistinctly, without taking into account that these are two completely different conditions, which, although they may sometimes present similar symptoms, have nothing to do with each other.
Immune system and digestive system
It is very important to clarify that in allergies there is a reaction of the immune system, Meanwhile in intolerances, the immune system plays no role, but it is a metabolic and digestive problem.
The food allergies they are produced because our immune system perceives that a substance, in principle harmless to our organism, is harmful, and consequently, acts disproportionately, causing a series of symptoms. On the contrary, a food intolerance It is a reaction of the digestive system to a food or other substance, due to an enzyme deficit of the organism that prevents metabolizing it correctly.
What are your symptoms?
It is true that both present similar digestive symptoms, such as belly pain, swelling, nausea, vomiting or cramping, among others. But allergy sufferers may have other respiratory symptoms, such as sneezing, coughing, asthma, swelling of the lips or mouth, eczema, hives or, most dangerously, anaphylactic shock.
Usually, most allergic reactions and food intolerance are mild, but sometimes allergies can trigger a serious medical condition, which requires urgent hospitalization.
Another key difference between the two conditions is the time it takes for symptoms to appear. Allergies have an immediate reaction, while intolerances the symptoms are not so clear and can take up to several hours to appear.
"Allergic people must completely eliminate the food or substance causing the allergy"
"With food intolerances, the body can gradually accept and tolerate small amounts of the food or substance ingested, without presenting symptoms or general discomfort"
What to do if you have an allergic or food reaction?
At the first symptoms of food allergy It is important that you take action quickly. The intake of a antihistamine medication can help control symptoms, but it's vital importance to go to a medical center to identify and control the reaction.
Allergic people should completely eliminate the food or substance causing the allergy.
With the food intolerances, the body can gradually accept and tolerate small amounts of the food or substance ingested without presenting symptoms or general malaise. Therefore, the visit to the doctor does not have to be so imminent. However, it is convenient to have a medical examination to undergo a Intolerance test and to detect food that is not tolerated, and thus be able to establish dietary and lifestyle guidelines.
