They are immune system reactions triggered by specific proteins in food. Common allergenic foods include peanuts, tree nuts, shellfish, fish etc. Symptoms can range from mild itching to severe and life-threatening anaphylaxis.

They involve difficulty digesting certain substances, often due to enzyme deficiencies or sensitivities. Lactose intolerance, gluten sensitivity, and fructose malabsorption are well-known examples. Symptoms may include bloating, diarrhea, abdominal pain, or headaches.

Allergy testing, such as skin prick tests or blood tests, can help diagnose allergies. For intolerances, suspected trigger foods are eliminated, and then gradually reintroduced to observe any symptoms. Seeking guidance from a registered dietitian can be immensely helpful during this process.
