What is an elimination diet primarily used for?

An elimination diet is primarily utilized for identifying food allergies and intolerances by systematically removing certain foods from a person's diet and then gradually reintroducing them to observe any adverse reactions. This method helps to pinpoint problematic foods that may be causing symptoms like gastrointestinal distress, headaches, or skin issues.

While determining food intolerances is a significant aspect of an elimination diet, it's important to note that it can also be quite effective for identifying food allergies. Both food allergies and intolerances can manifest through similar symptoms; however, an elimination diet's structured approach helps individuals to better understand their body's responses to specific foods.

The other options listed, such as weight management and enhancing nutritional intake, do not reflect the primary purpose of an elimination diet. Weight management focuses on calorie control and lifestyle changes rather than identifying problematic foods, while enhancing nutritional intake typically involves adding a variety of foods to promote overall well-being rather than removing them. As such, the role of an elimination diet is distinctly aligned with identifying food intolerances and allergies through its methodical approach.
