With the abundance of available specialties, such as gluten-, nut- or dairy-free products, it seems so nearly everyone However, a new study says that most people are unlikely to do so but falsely believe they have food allergies.
Northwestern University's study found that about 20 percent of respondents believe that However, only 10 percent actually experience reactions that indicate a true allergic reaction, and although the results indicate that food allergies are common, they are not as common as we think.
Phone surveys reported that more than 40,000 adults were suffering from a food allergy and then revealed whether they were self-diagnosing or by a test at the doctor's office. Volunteers received a list of reactions that indicated a true allergy, such as: Hives, swelling of the lip / tongue, tension in the chest and the question of what they have experienced. Overall, only 10 percent of people showed food allergies. The most common food allergies include mussels, milk and nuts.
Although the study found that few people have true food allergies, this does not mean that 10 percent of respondents have just invented something. Instead, the researchers believe that this group may suffer from food intolerances, as many experience stomach cramps or nausea after eating a trigger.
So what's the difference between the two? Intolerance involves the digestive system, so people with intolerance have gastrointestinal problems like gas or diarrhea because they can not digest certain foods, according to the American Academy of Allergy, Asthma & Immunology (AAAAI).
An allergy, on the other hand, affects the immune system and is much more difficult. Purvi Parikh, Allergist / Immunologist of the Allergy & Asthma Network.
In a food allergy, "your immune system produces antibodies to a particular food and can cause life-threatening reactions when exposed, whereas intolerance is more of a side-effect of a food that most people experience, but is not necessary to avoid eating," He explains MensHealth.com . "For example, lactose intolerance is due to a deficiency in an enzyme that breaks down milk, but this is very different from a milk allergy, which can be life-threatening in some patients," he says.
