Food sensitivity tests lack scientific support in Spain

Food sensitivity tests, widely marketed as a way to identify food intolerances, lack scientific backing and are not recommended by medical professionals. These tests, often costing hundreds of euros, are increasingly popular despite their questionable diagnostic value. Medical experts warn that these tests, which often measure IgG antibodies, can lead to misdiagnoses and unnecessary dietary restrictions. The tests are not used in the public health system and are discouraged by scientific societies due to a lack of evidence supporting their accuracy. The rise in these tests coincides with growing public interest in food sensitivities, but experts emphasize the importance of distinguishing between allergies and intolerances. Proper diagnosis of food-related issues requires established medical methods, not these unproven tests.
