How is that different from food intolerance?
Like a food allergy, a food intolerance is also an adverse reaction to food, but the body’s immune system is not involved. Lactose intolerance, for example, is when the body lacks the enzyme lactase needed to digest lactose, the sugar found in milk. Without the enzyme present, lactose remains undigested and ferments in the gut, resulting in gastrointestinal (GI) symptoms such as diarrhea, bloating or constipation. Lactose intolerance is therefore not the same as a milk allergy, which would involve the type of allergic reaction described above. The cause of other food intolerances may not be as easily identified but may trigger similar GI symptoms.
