"Lactose intolerance is the inability to properly digest lactose, the sugar contained in milk and dairy products," said registered nutritionist Danielle Fineberg, MS, RD. "It is caused by a lack of the enzyme needed to digest lactose and can lead to gas." , Bloating or diarrhea after eating dairy products. "
According to nutritionist and natural chef Karyn Forsyth Duggan, M.S., BBS, lactose intolerance is not just "no fun!" "However, it is estimated that up to 75% of the world's population will have and / or develop hypolactasia," a specific term for lactose intolerance that indicates a deficiency of the enzyme lactase in the gut. "Side effects on food include both food allergies and food intolerances," she adds. "Lactose intolerance does not affect the immune system, but is the result of the body's inability to digest / ingest / metabolize a food or a component of the food."
Megan Meyer, Ph.D., director of science communication at the International Food Information Council, agrees and notes that, unlike a real food allergy that triggers an immune system response, lactose intolerance is a disease that occurs in our digestive system and does not affect our immune system. Lactose intolerance occurs when the body has difficulty digesting lactose, a sugar found in dairy products. "
