A food allergy is an immune system reaction that causes histamines to protect it. Your body then remembers a particular food that triggers the immune system.
When you eat that food again, your histamine response is automatically withdrawn. Diagnosing food allergies is not easy. But here’s some information on allergy symptoms and how to spot them.
What are the most common food allergies?
According to the Department of Health and Human Services, the most common food allergies in the United States are:
- Tree nuts
- Cow’s milk
Most common food allergy symptoms and how to identify them?
Allergies often appear in childhood but can start at any age. These are the most common indicators.
Anaphylaxis is an acute reaction to something you eat. It starts shortly after eating and quickly gets worse. Symptoms of anaphylaxis are often the same as less severe reactions but may include symptoms such as:
- Respiratory problems
- Swollen tongue
- Feeling of tightness in our chest
- Difficulty swallowing or speaking
- Dizziness or fainting
- Total collapse
An anaphylactic reaction is a medical emergency. It is a fatal condition if not treated immediately. If you think someone has an anaphylactic response, call 911.
Food allergy symptoms can affect your skin. A bumpy, red discharge appears shortly after eating or coming into contact with food. This inflammation can occur in the mouth, face, neck, or anywhere food touches your skin. Other parts of your body may also have a rash.
Eczema is a common food allergy rash. Your skin becomes red, scaly, and inverted yellow. It is caused by an immune system response, environmental exposure, genetics, or stress. If you have eczema, your immune system reacts to everything from minor irritants to food allergies.
Follow an elimination diet if you notice a rash or other food allergy symptoms
Eczema food allergies can occur within minutes of eating a particular food, but delayed eczema reactions can happen an hour to two days later. To determine what caused this reaction, you can try an elimination diet.
Avoid common foods that cause eczema. After eliminating these foods for a few days, slowly add each food back into your diet.
Pay attention to reactions two days after eating. If there is no response, try adding another food. If your symptoms worsen after eating a food, avoid it. You can try adding it to your diet later to see if your eczema flares up. Common foods that cause eczema include:
- Dairy products
- Some spices: cloves, cinnamon, and vanilla
People with dyshidrotic eczema, a skin reaction that appears on the hands and feet, should avoid nickel foods. Nickel is a trace mineral found in the soil that passes into food. Some foods high in nickel should be known below:
- Canned meats
Some eczema sufferers are sensitive to birch pollen. Foods that cause reactions due to exposure to these pollens include:
- Green apples
Hives are another skin allergy symptom characterized by red welts or bumps. If it lasts up to six weeks, it is called acute urticaria; if it lasts more than six weeks, it is called chronic urticaria. Common foods that cause hives include:
If you are allergic to latex, these foods will also cause hives. Including:
Usually, hives appear an hour after eating.
4. Stinging or swelling in your mouth may be signs of food allergy
You may also react to certain foods if you have a dust allergy. Pollen allergies cause swelling or lumps in the mouth, throat, or tongue.
Not everyone with a pollen allergy experience these symptoms. If you are allergic to these pollens, here are some common foods to avoid:
- Grass pollens: Celery, tomato, peaches, apricot
- Ragweed Pollens: Banana, apricot, cucumber, zucchini, sunflower, artichoke, echinacea tea
- Birch pollen: Plums, pears, pears, almonds, apples, celery, cherry, hazelnut, kiwi
In addition to eliminating these foods from your diet, you can use natural antihistamines to help keep your dust allergies under control. A few common natural antihistamines are:
- Vitamin C
- Stinging nettle
- Bromelain enzyme
Alternative ways to help overcome your pollen allergy
- Nasal irrigation
- Exercise or sports activities
5. Asthma and arthritis can come from food allergies
Rarely do some foods trigger an asthma attack, but allergic symptoms are similar to asthma. One person developed whooping cough and cough after eating onions. It turns out he was allergic to mold, and it was growing on onion skins. Just eating onions gave him a respiratory reaction. Foods that can trigger an asthma reaction include:
- Dairy products
- Tree nuts
Oddly enough, you may have cardiac symptoms from a food allergy. Cardiac symptoms include:
- Become sick
- Low blood pressure
- Loss of consciousness (severe)
It is difficult to determine if you are experiencing a severe reaction. But if you feel them, you may have a more severe reaction than you think. Please do not ignore these symptoms, as they may be symptoms of other medical problems.
You may also be dealing with an anaphylactic shock reaction or a combination of allergy symptoms. Like hives and rushes combined with the above symptoms.
7. Stomach pain or diarrhea
Stomach problems due to food allergies are difficult to see. Maybe you have food poisoning or just an upset stomach. But if your symptoms persist, especially after eating a particular food, there’s a good chance you have a food allergy. Food allergies may cause gastrointestinal symptoms.
- Stomach pain
The foods that most often cause this type of allergic reaction are:
- Tree nuts
8. Skin growth and other reactions
There have been cases where people who get tattoos develop strange-looking skin tumors or growths. It usually happens a few months after getting a new tattoo. It’s more widespread than you might think. Related to tattoos is an allergy to ink. Your immune system detects a foreign substance and causes this reaction.
Although not as strange as a skin tumor, some food dyes cause allergic reactions. Here are some expected natural food dyes that cause food allergy symptoms.
- Carmine: A red food dye obtained from an insect. This food coloring is found in red yogurt, popsicles, and drinks.
- Saffron: Saffron is a yellow dye cultivated from plants that grow in Iran, France, Spain, parts of India, and Italy. It can be found in butter, cheese, sausage, and margarine.
- Annatto: This yellow dye comes from a tree in South America. You’ll see it in custards, cakes, and other baked goods.
Although the Food and Drug Administration (FDA) recommends these food dyes as safe, some people are allergic to them. If you experience allergy symptoms after eating foods with coloring, try an elimination diet to determine which shades you are allergic to. Food coloring refers to allergic symptoms:
- Sweating on face
- Chest tightness
- Flushed skin
Itching and itchy eyes can be food allergies. As histamine is secreted, secretions increase, and you mess with itchiness and sneezing.
Usually, the food allergy that causes the sneeze is mild. Some common foods that cause breakouts are eggs, soy, milk, nuts, and tree nuts.
10. Red buttocks
It’s embarrassing, but some food allergies give you a red bum. A bright red nail bothers and appears around the inner thighs, anus, and genitals. This allergic reaction may be due to an allergy to metals such as gold, mercury, or nickel. If you have these symptoms, avoid these foods in your diet.
- Foods with nickel: Licorice, buckwheat, cocoa powder, soy, soy sauce, tofu, coriander, figs, clams.
- Food with mercury: Swordfish, Tuna, Marlin, Orange roughy, Chilean sea bass, king mackerel.
- Gold: This metal appears in side dishes and resembles fillings such as leaf-shaped garnishes, vials, and dust. These can occur in cakes, soups, pasta, sushi, wine, and cocktails.
If your symptoms persist after eliminating these foods, you may have a more severe infection, such as a sexually transmitted infection (STI or STD). Get treatment immediately.
11. Food allergy mixed with exercise
You may experience sports-related food allergies. As strange as it sounds, this food allergy symptom can sometimes lead to anaphylaxis. It is called food-dependent exercise-induced anaphylaxis. Also, taking non-steroidal anti-inflammatory drugs (NSAIDs) or drinking alcohol can cause an allergic reaction in people with this syndrome.
Dealing with food allergies
Knowing what foods you are allergic to, you can stay away from those foods. For some foods, this can be simple. For others, it may require some modifications.
To ensure that the food you eat is free of allergies, you must be vigilant in reading the ingredients and checking the menus. In restaurants, you need to check with servers and cooks.
Final thoughts on recognizing food allergy symptoms and how to narrow down the exact allergy
A food allergy is an immune system reaction that causes histamines to protect your body. Diagnosing a food allergy is tricky, but there are common food allergy symptoms to look out for.
Dizziness, sneezing, red rash, and intestinal problems are the most common allergic reactions. If you are allergic to a particular food, eliminate the problem.
