Food sensitivity refers to an adverse reaction that occurs when a person consumes certain foods or beverages. This can manifest in various ways, such as digestive issues like bloating and gas, skin problems like rashes and acne, headaches, joint pain, fatigue, and other symptoms. Food sensitivities are different from food allergies because they do not involve the immune system; instead, they result from an individual's body reacting to specific proteins in certain foods. Identifying and avoiding these problematic foods can help alleviate symptoms for those with food sensitivities.
