Detailed answer

Yes, dark spots can sometimes be caused by a food allergy. Certain food allergies can trigger a condition called allergic contact dermatitis, which can lead to skin discoloration. When the body reacts to an allergen, it can cause inflammation and damage to the skin cells, resulting in the formation of dark spots. It is important to identify and avoid the specific food allergen that is causing the reaction to prevent further dark spots and other allergic symptoms. Consulting with a dermatologist or allergist can help in diagnosing food allergies and providing appropriate treatment options.
