Food allergies are a serious and potentially life-threatening condition that affects millions of people around the world. According to the World Health Organization, food allergies affect about 6-8% of children and 3-4% of adults globally. Food allergies occur when the immune system mistakenly identifies certain proteins in food as harmful and triggers an inflammatory response. This can cause a range of symptoms, from mild to severe, such as itching, hives, swelling, vomiting, diarrhea, breathing difficulties, and anaphylaxis.
While any food can cause an allergic reaction, most food allergies are caused by just 10 foods. These are: milk, eggs, peanuts, tree nuts, soy, wheat, fish, shellfish, sesame, and mustard. These 10 foods account for 90% of food allergic reactions in the United States and are also common allergens in other parts of the world.
In this blog post, we will explore each of these 10 food allergies in more detail, including their symptoms, causes, diagnosis, treatment, and prevention. We will also answer some frequently asked questions about food allergies and provide some useful resources for further information.
Milk Allergy
Milk allergy is one of the most common food allergies, especially among children. It affects about 2-3% of infants and toddlers, and most of them outgrow it by the age of 5. However, some people may continue to have a milk allergy into adulthood.
Milk allergy is caused by an immune reaction to one or more of the proteins in cow’s milk, such as casein or whey. People with a milk allergy may also react to other animal milks, such as goat, sheep, or buffalo milk, as well as dairy products made from milk, such as cheese, yogurt, butter, cream, or ice cream.
Milk allergy symptoms can vary from person to person and may include:
- Skin reactions, such as rashes, hives, eczema, or swelling
- Gastrointestinal symptoms, such as nausea, vomiting, diarrhea, abdominal pain, or bloating
- Respiratory symptoms, such as sneezing, coughing, wheezing, or asthma
- Anaphylaxis, a severe and potentially fatal allergic reaction that involves multiple organ systems and can cause low blood pressure, rapid heartbeat, difficulty breathing, loss of consciousness, or shock
Milk allergy is diagnosed by a doctor based on the patient’s medical history, physical examination, and allergy tests, such as skin prick tests or blood tests. The only way to treat a milk allergy is to avoid all sources of milk and dairy products. People with a milk allergy should also carry an epinephrine auto-injector (such as an EpiPen) in case of accidental exposure and anaphylaxis.
Some people with a milk allergy may be able to tolerate certain forms of milk or dairy products, such as baked goods, fermented products, or extensively hydrolyzed formulas. However, this depends on the individual’s sensitivity and the type and amount of milk protein involved. Therefore, it is important to consult a doctor or an allergist before introducing any milk or dairy products into the diet.

Frequently Asked Questions
Here are some common questions and answers about food allergies and the 10 most common food allergens.
Q: What causes food allergies?
A: Food allergies are caused by an abnormal immune response to harmless proteins in food. The immune system produces antibodies called immunoglobulin E (IgE) that bind to the food proteins and trigger the release of chemicals such as histamine that cause inflammation and allergic symptoms.
Q: How are food allergies diagnosed?
A: Food allergies are diagnosed by a doctor based on the patient’s medical history, physical examination, and allergy tests. Allergy tests can include skin prick tests, blood tests, oral food challenges, or elimination diets. Skin prick tests involve placing a small amount of the suspected food allergen on the skin and pricking it with a needle to see if a reaction occurs. Blood tests measure the level of IgE antibodies to specific food allergens in the blood. Oral food challenges involve giving the patient increasing doses of the suspected food allergen under medical supervision to see if a reaction occurs. Elimination diets involve removing the suspected food allergen from the diet for a period of time and then reintroducing it to see if a reaction occurs.
Q: How are food allergies treated?
A: The only way to treat food allergies is to avoid the food allergen and any products that contain it. There is no cure for food allergies, but some treatments can help reduce the severity of the symptoms or prevent anaphylaxis. These include antihistamines, corticosteroids, and epinephrine. Antihistamines can help relieve mild to moderate symptoms such as itching, hives, or runny nose. Corticosteroids can help reduce inflammation and swelling. Epinephrine is a medication that can reverse the effects of anaphylaxis and should be administered as soon as possible in case of a severe allergic reaction. People with food allergies should always carry an epinephrine auto-injector (such as an EpiPen) with them and know how to use it.
Q: How can food allergies be prevented?
A: There is no definitive way to prevent food allergies, but some strategies may help reduce the risk or delay the onset of food allergies in some people. These include early introduction of allergenic foods, breastfeeding, probiotics, and vitamin D. Early introduction of allergenic foods means giving small amounts of foods such as peanut, egg, or fish to infants as early as 4 to 6 months of age, as long as they are developmentally ready and have no signs of food allergies. This may help the immune system to tolerate the food and prevent the development of food allergies.
Q: What are the best sources of vitamin D?
A: The best source of vitamin D is sunlight. When the skin is exposed to ultraviolet rays, it produces vitamin D. However, the amount of vitamin D that can be made from sunlight depends on many factors, such as the time of day, the season, the latitude, the skin color, the age, and the use of sunscreen. Generally, 10 to 15 minutes of sun exposure on the face, arms, and legs a few times a week is enough to meet the daily vitamin D requirement for most people. However, some people may need more or less sun exposure depending on their individual factors.
Another source of vitamin D is food. However, there are not many foods that naturally contain vitamin D. The main dietary sources of vitamin D are fatty fish (such as salmon, tuna, and sardines), fish liver oils, egg yolks, and some mushrooms. Some foods are also fortified with vitamin D, such as milk, yogurt, cheese, margarine, cereals, and orange juice. However, the amount of vitamin D in these foods may vary depending on the brand and the country.
A third source of vitamin D is supplements. Vitamin D supplements are available in different forms, such as tablets, capsules, drops, or sprays. The most common forms of vitamin D in supplements are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is more potent and more easily absorbed by the body than vitamin D2. The recommended daily intake of vitamin D for most people is 600 IU (15 mcg), but some people may need more or less depending on their age, health status, and risk factors. It is advisable to consult a doctor before taking vitamin D supplements, as too much vitamin D can cause toxicity and adverse effects.
Q: How can I prevent or treat food allergies?
A: There is no cure for food allergies, but there are some ways to prevent or treat them. The most important way to prevent food allergies is to avoid the food allergen and any products that contain it. This may require reading food labels carefully, asking about the ingredients of food prepared by others, and carrying an emergency kit with medication and an epinephrine auto-injector (such as an EpiPen) in case of accidental exposure and anaphylaxis.
Another way to prevent food allergies is to introduce allergenic foods early and often to infants, as long as they are developmentally ready and have no signs of food allergies. This may help the immune system to tolerate the food and prevent the development of food allergies. Some of the foods that should be introduced early and often include peanut, egg, fish, and sesame. However, this should be done under the guidance of a doctor or an allergist, especially if there is a family history of food allergies or other allergic diseases.
A third way to prevent or treat food allergies is to take probiotics or vitamin D supplements, as they may have beneficial effects on the gut microbiome and the immune system. However, the evidence for this is still limited and more research is needed to confirm the optimal dose, duration, and type of probiotics or vitamin D for food allergy prevention or treatment. Therefore, it is important to consult a doctor or an allergist before taking probiotics or vitamin D supplements, as they may have interactions or side effects with other medications or conditions.
