Supplementing the diet with Lactase Enzyme makes milk products more readily
digestible, helping to relieve discomfort caused by lactose
You have heard about
lactose intolerance. Such people must either not consume any lactose
(milk sugar), or artificially break it down in the milk, ice cream or
cheese before they eat those things. Do you know anyone who is
Let's look at the human ingestion of lactose. Back
in cave-days, the only time a person would ever ingest lactose would
be when they were infants and getting milk from their mothers.
Thereafter in their lives milk was never consumed. Only with the
invention of agriculture and animal husbandry has milk become readily
available to adults. Do you know of any cultures that still rarely
have milk products available to adults? Did you ever get ice cream in
a Chinese restaurant? Many people of Oriental or African descent are
extremely lactose intolerant as adults. They often get violently
nauseated upon eating a spoonful of lactose. As a matter of fact,
most of you would feel a bit strange after a tablespoon of lactose.
You probably aren't violently lactose intolerant, but actually
lactose tolerant, but still not lactose degraders. Babies are lactose
degraders because in that period of their development genes are
turned on that lead to the production of lactase - the enzyme that splits the disaccharide we
Lactose is a disaccharide with one glucose sugar
molecule bound to one galactose sugar molecule. Once lactose is
split, our bodies readily metabolize the glucose and galactose
products. Now, can you think of any other developmental stage in
which a person produces lots of lactase?
When else in a human's lifetime is there lots of lactose in the body?
The nursing mother, of course, makes lactose to put into her milk to
feed her baby. She uses lactase to catalyze the reverse reaction: glc + gal
-> lactose. Later, the baby takes it in the opposite direction:
splits the lactose, and the glucose mostly is metabolized for energy,
and some of the galactose goes into making brain material. Hence,
generally the more intelligent the mammal, the more lactose in
