There are people who have intolerance to the consumption of certain foods, which can cause discomfort, itching and even swelling in some parts of the body.
Specialists point out that food allergy is an abnormal response triggered by the body’s immune system. Symptoms of a food allergy include, but are not limited to: itchy and swollen mouth, vomiting, diarrhea or abdominal cramps and pain, rash or eczema, throat tightness and difficulty breathing and low blood pressure, according to information from MedlinePlus Medical Library.
The FDA, the United States government agency responsible for food regulation, says that while some treatments are being developed, there is no cure for food allergies.
Medical diagnosis to determine which foods cause a person to have an allergic reaction and strict avoidance of those foods are important ways to prevent serious adverse health effects.
In the list of foods that are consumed permanently that can cause more allergies to both adults and minors, are, among others, the following.
Products such as walnuts, peanuts, almonds, pistachios, cashews, sunflower or pumpkin seeds, hazelnuts and sesame seeds can act as allergens and trigger an immune hypersensitivity reaction in the body. According to the Cinfasalud portal, from Spain, nuts contain certain proteins that can cause allergies in some people.
The consumption of these foods or any product that contains them can cause the body to begin to release chemicals such as histamine, which can cause itching in the mouth, inflammation of the lips, rhinitis, hives, breathing difficulties, coughing or sneezing and digestive symptoms such as diarrhea, vomiting, or stomach pain.
Other foods that cause allergies are fish and shellfish. However, there may be people who tolerate fish, but can’t stand shellfish. There are also consumers allergic to dairy products such as milk, due to their intolerance to lactose.
Eggs are also characterized by generating these drawbacks. According to the Mayo Clinic research institute, egg allergy reactions vary from person to person and usually occur shortly after eating eggs.
When a person is allergic to this food, they may experience skin inflammation or hives, nasal congestion, digestive symptoms such as colic, nausea and vomiting, and other signs such as coughing, wheezing, chest tightness, or shortness of breath.
In the particular case of children, according to the Healthy Children portal, the foods that can cause allergies the most are cow’s milk, eggs, peanuts, soybeans, wheat, almonds, fish such as tuna, salmon and cod and shellfish, especially shrimp and lobster.
“Peanuts, tree nuts, and shellfish are the most common cause of severe reactions. Allergies can also occur due to other foods such as meats, fruits, vegetables, grains and seeds such as sesame seeds”, specifies this website.
The good news is that these discomforts are usually outgrown during early childhood. It is estimated that between 80% and 90% of these allergies disappear by the time the child is over five years of age.
However, some allergies are more persistent and therefore, according to the aforementioned source, one in five children will outgrow an allergy to peanuts, while very few will do so to nuts and shellfish, so the recommendation is that the pediatrician monitor the evolution of these situations.
According to MedlinePlus, in rare cases, food additives such as dyes, thickeners and preservatives cause food allergies or intolerance reactions.
Finally, there are people who have an oral allergy. This is a syndrome that affects the mouth and tongue after eating certain fresh fruits and vegetables such as melons, apples, pineapple, and other foods that contain similar substances.
