Peanuts are one of the most common causes of serious allergic reactions. Even small amounts of peanuts can be enough to trigger an allergic reaction. People who have been diagnosed with food allergies are more likely to develop other food allergies (like peanut allergy) than those without food allergies. If food allergies are genetic, your risk for developing an allergy increases. People with eczema also tend to develop food allergies.
Keep a record of all the foods you eat and any allergic symptoms like swelling, itchiness, nausea, headache or any other discomfort that occurs. This will be helpful in determining which food items to avoid and truly know whether you’re allergic to a certain food type. Peanuts are found in a variety of foods including snacks, cereals and take-out foods, so it’s important to keep a food chart.
You can try an elimination diet by avoiding foods that contain peanuts by reading the labels carefully. An elimination diet can last for anywhere between 2-8 weeks. If you experience any allergenic symptoms when you include the food again, then you can consult your doctor with the food chart to determine whether you have a peanut allergy.
