What Causes Food Allergies in Children?
Food allergies in children can be triggered by various factors. One key aspect in the development of food allergies is sensitization, which occurs when a child is exposed to a particular food for the first time. Sensitization can also happen through breast milk if the mother consumes allergenic foods.
During subsequent exposures to the allergenic food, the immune system produces specific antibodies called IgE antibodies. These antibodies recognize the food as harmful and trigger an immune response. The release of histamines by the IgE antibodies leads to the manifestation of allergic symptoms.
The symptoms of food allergies can vary from mild to severe and may include hives, asthma, itching, breathing difficulties, stomach pains, vomiting, and diarrhea. Each individual may experience a different combination of symptoms, and the severity of the reaction can also vary.
It is important to note that not all children who are exposed to a specific allergen will develop an allergic reaction. The exact reasons for why some children develop allergies while others do not are still being studied. However, there are various factors that may contribute to the development of food allergies, including genetics, environmental factors, and the timing and method of introducing certain foods during early childhood.
Difference Between Food Allergy and Food Intolerance
When it comes to adverse reactions to certain foods, it’s important to distinguish between food allergy and food intolerance. While both can result in uncomfortable symptoms, they differ in terms of the immune system’s response and the potential severity of the reaction.
A food allergy involves an immune system response to specific proteins in certain foods. This immune response triggers the release of chemicals, such as histamines, which can cause a wide range of symptoms and even life-threatening reactions. The symptoms of a food allergy can include hives, swelling, itching, difficulty breathing, and lowered blood pressure.
On the other hand, a food intolerance does not involve the immune system. It occurs when the body has difficulty digesting certain foods or substances, leading to digestive symptoms such as discomfort, bloating, gas, and diarrhea. While the symptoms of food intolerance can be similar to those of a food allergy, they typically do not pose a life-threatening risk.
It is crucial to differentiate between food allergy and food intolerance to ensure appropriate management and treatment.
Understanding the difference between food allergy and food intolerance is essential for accurate diagnosis and appropriate management. If you suspect that you or your child may have a food allergy or food intolerance, it is recommended to consult with a healthcare professional for evaluation and guidance.
Most Common Food Allergens in Children
Approximately 90% of food allergies in children are caused by eight common allergens: milk, eggs, peanuts, tree nuts, fish, shellfish, wheat, and soy. These allergens can trigger adverse reactions in susceptible individuals, leading to a range of symptoms. Let’s take a closer look at each of these common food allergens:
