Lactose intolerance is the inability to metabolize lactose, a sugar found in milk and other dairy products, because the required enzyme lactase is absent in the intestinal system or its availability is lowered.
To assess lactose intolerance, the intestinal function is challenged by ingesting more dairy than can be readily digested.
Clinical symptoms typically appear within 30 minutes but may take up to 1-2 hours depending on other foods and activities.
Substantial variability of the clinical response (symptoms of nausea, cramping, bloating, diarrhea, and flatulence) are to be expected as the extent and severity of lactose intolerance varies between individuals.
The dairy industry has created quality low-lactose or lactose-free products to replace regular dairy.
Plant based milks and derivatives are the only ones to be 100% lactose free: soy milk, almond milk, oat milk, rice milk, peanut milk, horchata.
When lactose avoidance is not possible or on occasions when a person chooses to consume such items, then enzymatic lactase supplements may be used.
Lactase enzymes similar to those produced in the small intestines of humans are produced industrially by fungi of the genus aspergillus. The enzyme, B-galactosidase, is available in tablet form: LACTAID ULTRA.
The Lactaid Ultra tablets should not be taken on an empty stomach because too much acid can denature it.
