Nausea and Vomiting
Vomiting and nausea are two common signs of food allergies. They happen when you consume a triggering food that can cause the immune system to overreact. More specifically, the body identifies them as a danger and activates the protective response. However, food allergies do not only involve vomiting and nausea. You need to notice other signs mentioned above. Otherwise, they can be an indicator of food intolerance or food poisoning. [4]
