Among the various food allergies that we can find in our society, one of the most prevalent is the one for the nuts .First, though, we distinguish between allergy and intolerance . ‘s food allergy is a specific form of intolerance to food or food component that activates the immune system, an allergen (a protein in risk, which in the majority of people are completely harmless) triggers a chain of reactions of the immune system, including the production of antibodies. These antibodies trigger the release of organic chemicals, such as histamine, which cause a variety of symptoms: itching, runny nose, coughing or wheezing. Allergies to food or food components are often hereditary and are usually diagnosed early in life.


Food intolerance affects your metabolism, but not the immune system. A typical example is lactose intolerance: people who are affected have a deficiency of lactase, the digestive enzyme that breaks down milk sugar. Features The dried fruit is filled with many virtues, including fats vegetable (plant lipids), particularly useful for the circulation and health in general, the dietary fiber and many vitamins. But for some people these positive elements can not be exploited, because some, especially linked to the protein component of this category of fruit, it can trigger an allergic reaction can be severe, so it is appropriate to carefully avoid consumption.

It is, therefore, , a disease of a serious nature, because it starts at an early age, it lasts for a lifetime and can be lethal. Peanuts, walnuts, almonds, Brazil nuts, hazelnuts can cause symptoms even with minimal contact with skin or by inhalation. The symptoms usually are: rashes, nausea and headache, swelling of the tongue and lips, prophylactic shock.

Often you may have noticed, for example the words “This product may contain traces of nuts” here, this is a form of communication to the final consumer. What is an allergen?
