According to the doctors at Mayo Clinic, certain reaction to different foods is quite common, but such reactions can also be the result of food intolerance and is not always because of a food allergy.
The signs and symptoms of food allergies and food intolerances do overlap at times. That is why people often confuse between the two.

According to the American Academy of Allergy Asthma & Immunology, the response of a food allergy takes place in the immune system as opposed to the reaction of a food intolerance that occurs in the digestive system.

Other causes of food intolerance according to the Mayo Clinic's doctors may be:
Irritable Bowel Syndrome which causes constipation, diarrhea and abdominal pain.
Sensitivity to additives in dried foods, wines, canned food can be a trigger for asthma patients.
According to AAAAI, your immune system defends your body from the foods that act as allergens.
They fight these invaders by producing the cells called immunoglobulin E (IgE). Unlike food intolerance, you can experience food allergies even by touching or smelling the food.
According to the doctors at Mayo Clinic, other causes of food allergies may be:
A family history of allergies, hay fever, eczema or asthma.
Food allergies are more common in infants or babies, but it generally resolves itself as the digestive system matures.
Asthma and food allergy have higher chances of occuring together.
