Food allergies affect millions of people worldwide, causing a range of unpleasant symptoms and potentially life-threatening reactions. In this article, we’ll explore what food allergies are, what causes them, who is at risk, and what to do if you suspect you may be allergic to certain foods.
What are Food Allergies?
Food allergies occur when the immune system mistakenly identifies a particular food or ingredient as harmful and triggers an allergic reaction. The body produces an antibody called Immunoglobulin E (IgE), which releases histamine and other chemicals into the bloodstream. This can cause a range of symptoms, from mild to severe, including skin rashes, digestive problems, and anaphylaxis.
Causes of Food Allergies
The causes of food allergies are not fully understood, but research has identified several risk factors that may increase the likelihood of developing an allergy. These include:
- Genetics: People with a family history of allergies are more likely to develop food allergies.
- Environmental factors: Exposure to certain pollutants, chemicals, or allergens may increase the risk of developing allergies.
- Early introduction to allergenic foods: Introducing certain foods too early in life, or too quickly, may increase the risk of developing an allergy.
Common Food Allergies
While any food can cause an allergic reaction, there are eight foods that are responsible for most food allergies. These include:
- Milk
- Eggs
- Peanuts
- Tree nuts (such as almonds, cashews, and walnuts)
- Fish
- Shellfish
- Soy
- Wheat
Symptoms of Food Allergies
Symptoms of food allergies can vary from person to person and may range from mild to severe. Common symptoms of food allergies include:
- Itching or tingling in the mouth
- Hives or rash
- Swelling of the lips, tongue, or throat
- Abdominal pain, nausea, or vomiting
- Diarrhea
- Difficulty breathing or wheezing
- Anaphylaxis (a severe, life-threatening reaction)
