Strawberries are loved by many, whether fresh, in desserts, smoothies, or jams, thanks to their sweet flavour and vibrant colour. But for some people, these popular berries can trigger an allergic reaction. While strawberry allergies aren’t as common as allergies to nuts or shellfish, they can range from mild irritation to potentially serious, life-threatening responses. If you find yourself experiencing unusual symptoms after eating strawberries, it’s important to understand what might be happening. Knowing the signs, risk factors, and how to manage a strawberry allergy can help you stay safe while still enjoying a healthy, balanced diet.
What is a strawberry allergy
A strawberry allergy occurs when the immune system mistakenly identifies a protein in strawberries as harmful. In response, the body triggers an allergic reaction. Interestingly, some people with this allergy can tolerate cooked strawberries because heating can alter the protein structure.
Strawberry allergies are relatively rare, particularly in older children and adults. According toa study published in Clinical and Experimental Allergy, around 3-4% of children under the age of two may experience a strawberry allergy, with the prevalence dropping to 0.5-1% as children get older. While rare, these allergies can still cause significant discomfort or, in severe cases, life-threatening reactions. Individuals who suspect they may be allergic to strawberries should consult a healthcare professional for proper testing and guidance to confirm the allergy and learn how to manage it safely.
