About 75% (three-quarters) of all adults produce less lactase as they grow older.
This is only an approximate figure. In parts of Europe it is about 5%, and in parts of Asia above 90%.
The condition is known as lactose intolerance, because without the enzyme people cannot digest the sugar lactose. The lactose is therefore not absorbed and travels further along the gut, where bacteria act on it and produce gases, which cause considerable discomfort.
Lactose is particularly found in milk, and people with lactose intolerance have to avoid dairy foods as far as possible.
the enzyme, lactase
Milk contains a sugar called Lactose which all (the vast majority) of child can digest as they produce a enzyme called Lactase which metabolizes it. In a good deal of adult the ability to produce Lactase is lost and the presence of milk in the intestines leads to painful conditions. I hesitate to call Lactose unhealthy but in certain conditions it is.
Fitness is a term that is used to measure the ability to survive and produce the most offspring.
no, this only happens when you insufficiently produce lactase.
fitness
Most mammals normally cease to produce lactase, (and become lactose intolerant), after weaning. However, some human populations have developed lactase persistence (and therefore can eat dairy after adulthood). This said, research reveals intolerance to be more common globally than lactase persistence. The frequency of lactose intolerance ranges from 5% in Northern European to more than 90% in some African and Asian countries. That would mean that 95% of people form European stock and 10% of people from African and Asian stock are "not lactose intolerant".
It helps with lactose intolerance because contains the enzyme Lactase which if you are Lactose intolerant you body doesn't produce this enzyme and the enzyme lactase in Lactaid pills breaks down the milk sugar(Lactose) making it easier for your body to digest dairy foods. Taken off of my box of Lactaid
Lysosome. Which fails to produce the enzyme lactase. (source : medical forum)
That would depend upon which enzymes; lactase would break it down, others produce cheese, kefir, etc.
The population of Hollandia Produce is 70.
KM Produce's population is 33.
The human body has many enzymes that help break down the food you eat- for instance when you eat chicken the protein is broken down by an enzyme called protease when you eat milk- the sugar in it called lactose- is broken down by lactase When babies are born their bodies produce a large amount of lactase to digest their mother's milk/formula As Certain people get older the amount of lactase in the body decreases-making it hard to digest milk and milk products
