Identifying food intolerances can be achieved through a combination of methods, including elimination diets, symptom tracking, and professional testing. An elimination diet involves removing potential allergens for a period, then gradually reintroducing them to assess reactions. Keeping a detailed food journal helps correlate symptoms with specific foods consumed. Consulting a healthcare professional can also provide necessary tests to diagnose intolerances accurately. Recognizing these intolerances allows for better dietary choices and improved digestion and overall health.
