Celiac.com 09/06/2018 - What are the most common foods that can trigger allergic reactions in people?
First, and it's important to be clear about this, a food allergy is not to be confused with a food sensitivity. Food sensitivities are common and usually harmless, if sometimes uncomfortable. Food sensitivity can cause symptoms like gas, bloating, stomach upset, indigestion, and the like when some people eat certain foods.
According to WebMD, these nine foods account for about 90% of all food allergies:
- Tree nuts, such as walnuts, almonds, pine nuts, brazil nuts, and pecans
- Wheat, barley, and rye—Celiac disease
Mild symptoms of a food allergy reaction include:
- Red, swollen, dry, or itchy skin and rash (hives or eczema)
- Runny or stuffy nose, sneezing, or a slight, dry cough
- Itchy, watery, red eyes
- Itchy mouth or inside your ear
- Funny taste in your mouth
- Upset stomach, cramps, vomiting, or diarrhea
Though any of these foods can cause an allergic reaction, peanuts, nuts, fish, and shellfish are well known for causing severe allergic reactions.
Symptoms of a sever allergic reaction to food include:
- Trouble breathing or swallowing
- Swollen lips, tongue, or throat
- Feeling weak, confused, or light-headed, or passing out
- Chest pain or a weak, uneven heartbeat
If you suspect that you or someone you know is having an allergic reaction to food, especially a severe reaction, definitely seek medical attention immediately.
