Banana allergy or intolerance is a reaction to consuming bananas or banana-containing foods. Banana allergy is caused by an immune system response to certain proteins found in bananas and can result in symptoms such as itching, hives, swelling, nausea, vomiting, coughing, sneezing, diarrhoea, and in severe cases, anaphylaxis. The symptoms of banana intolerance are gastrointestinal such as bloating, gas, discomfort, changes in bowel movements and diarrhoea, and are generally caused by the body's inability to effectively break down the food.
Allium intolerance is a condition in which a person has difficulty digesting foods from the Allium family, such as onions, garlic, shallots, leeks, and chives. This can result in symptoms such as bloating, flatulence, and abdominal pain after consuming these foods. Some people with allium intolerance may have a sensitivity to the sulphurous compounds present in allium vegetables, while others may have a specific enzyme deficiency that affects their ability to digest these foods.
Cow's milk allergy (CMA) is an adverse immune reaction to one or more of the proteins found in cow's milk. It is one of the most common food allergies in infants and young children. The reaction can occur immediately or within a few hours after consuming cow's milk and the symptoms can vary from mild to severe.
Chocolate allergies are genuine, though uncommon. Reactions can range from mild — an upset stomach or itchy skin — to more serious symptoms such as swelling or difficulty breathing. In many cases, discomfort after eating chocolate isn’t a true allergy at all, but a reaction to something else in the recipe, such as caffeine, sugar, or lactose, especially in more processed chocolate.
