Food intolerance analysis involves testing to identify adverse reactions to specific foods, which can cause symptoms such as digestive discomfort, headaches, or skin issues. Unlike food allergies, which involve an immune response, food intolerances are typically related to difficulties in digesting certain substances. Testing methods may include blood tests to measure antibodies or other markers associated with food intolerance. Understanding and managing food intolerances can help individuals avoid trigger foods, improve their overall health, and alleviate symptoms related to dietary sensitivities.
