As Raquel Soriano, a general practitioner at SHA, tells us, \u2018A food allergy is <strong>an inappropriate reaction to the ingestion, contact or inhalation<\/strong> of a specific external agent, known as an allergen. It occurs when the <strong>immune system<\/strong> mistakenly identifies a food or a substance present in it as harmful and, in response, releases antibodies, called immunoglobulin E, to neutralise it\u2019.<\/p>\n<p>Not all the factors that influence this increase are yet known, but what is clear is that <strong>environmental<\/strong> factors play a role. \u2018Pollution, an unhealthy lifestyle, and nutrition are fundamental. We know that a <strong>diet based on ultra-processed foods and rich in sugars causes a variation in the intestinal flora<\/strong>. As a result, this may be one of the main reasons for the increase.<\/p>\n<p><strong>Genetic factors<\/strong> also play a role: if there is a history of allergic disease in a family, the likelihood of any of the offspring suffering from allergic disease increases by 5-15%. Although the genetic code cannot be altered, thanks to <strong>epigenetics<\/strong> we can modulate, activate, or deactivate the expression of genes without modifying the DNA sequence. In other words, a certain genetic tendency can be reversed with healthy lifestyle habits,\u2019 adds Raquel. To learn more about the role of food in gene function, <strong><a href=\"https:\/\/shawellness.com\/shamagazine\/en\/epigenetics-the-role-of-diet-in-how-genes-work\/\">Click here<\/a><\/strong><\/p>\n<p>However, not all adverse food reactions are the same. As the doctor explains, \u2018There are <strong>toxic<\/strong> ones, which are intoxications, and anyone can suffer from them. For example, if you eat poisonous mushrooms. And then there are the <strong>non-toxic<\/strong> ones, which are divided into three groups:<\/p>\n<ul>\n<li>immunoglobulin E-mediated immunological ones, which are food allergies.<\/li>\n<li>non-immunoglobulin E-mediated immunological ones, such as coeliac disease<\/li>\n<li>non-immunological ones, which are intolerances, such as lactose intolerance\u2019.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>Food allergies are highly dependent on geography because they are directly <strong>related to diet<\/strong> and, in different countries and cultures, the most commonly consumed foods vary. In Spain, the most common allergies are to <strong>cow&#8217;s milk protein, eggs, fish, <\/strong>seafood, pulses, especially lentils and soya, and grains. In the United States, on the other hand, it is peanuts.<\/p>\n<p>Dr Soriano stresses one element that is important to bear in mind: <strong>cofactors<\/strong>. \u2018There are situations in which the <strong>threshold of tolerance to the allergen<\/strong> may decrease and this entails the risk of suffering a reaction with a dose that was previously tolerated. The most important cofactors are exercise, infections, <strong>alcohol, fasting, stress<\/strong>, anti-inflammatory drugs, and proton pump inhibitors. As such, there are people who can tolerate a minimal amount of a food with an allergic basis, but who, when consuming it in these situations, still suffer the reaction\u2019.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Healthy nutrition, rich in fresh and seasonal foods, is the first step in keeping the gut flora balanced.
