What is the difference between a food allergy and intolerance?
While both food allergies and intolerances can cause unwanted reactions after consuming certain foods, they differ in their underlying mechanisms. Food allergy occur when the immune system mistakenly identifies a specific protein in the food as harmful, triggering an allergic response. This response can range from mild (itching, hives) to severe (anaphylaxis) and requires immediate medical attention. On the other hand, food intolerance is a non-immune reaction that typically involves the inability to properly digest or metabolize a specific food component, such as lactose or gluten. The symptoms of food intolerance are generally less severe and may include digestive issues like bloating, gas, or diarrhea. While both conditions require dietary modifications, food allergies necessitate strict avoidance of the allergen, while food intolerances may allow for limited consumption under certain circumstances.
Allergies are a frequent health issue that can emerge or appear at any age. While there is no cure for allergies at the moment, there are effective treatment options available to ease symptoms and enhance quality of life. Seeking competent medical guidance, recognizing regional characteristics, and taking proper precautions can all help with allergy treatment. When dealing with allergies, it is critical to be informed, be proactive, and prioritise your health.
