Their bodies cannot digest as much lactose as other people's bodies.
In general, adults do not need milk. It has been enriched to provide a good source of Vitamin D, Riboflavin, Vitamin B12, Calcium and Phosphorus, but is high in fat and sugars. By adulthood, most people do not have the ability to digest lactase, found in milk. This ability is a genetic variant, developed by pastoral populations.
because it was light to drink
It will take about 24-72 hours to go from the mouth to the anus.
Toast does not need too much time to digest and will require slightly over an hour. As a matter of fact toast will digest faster than milk which takes up to 2.5 hours.
Very. The stomach can't hold so much of something as hard to digest as milk.
I don't really know
They won't die from drinking milk, but dogs should not consume too much diary products as it can upset their stomach, since they find it difficult to digest.
lactose intolerance is were you are unable to digest the protein lactose in milk because your body doesn't produce lactase to break it down into sugars. When you are young and feeding on your mothers milk, (or bottle fed) the genes that are responsible for the production of lactase are activated. But as you grow older these genes become in active. it western cultures, these genes remain active as we have social presures for the consumption of milk. (such as eating ice cream) People like you who dont produce the lactase are called lactose intolerant. Its not really some thing you can treat. Different people have different levels of lactose intolerance. Find out how much milk you can have before being sick or change to thing like soy milk or instead of ice cream have sorbet instead. But to answer your first question nothing as it does not work that way. the lactase must be produced by the body.
General meaning:Lactose intolerance is results of an inability to digest or to metabolize lactose.due to missing or defective enzymes (inborn error of metabolism)Flow:ingested milk productsbuildup of dissacharides because deficiency of lactase in the intestinal villi.so, lactose cant be degraded to galactose and glucosecant be absorbed in to the bloodstream from the villilactose will accumulatedproducing H2, CO2 and organic acids.digestive problems: bloating and diarrheaNote that the common definition for "lactose intolerance" excludes infants. Virtually all human infants (indeed all mammal infants) are able to digest lactose, as it is a key ingredient in gaining sustenance from their mother. Infants not able to digest lactose are much more rare (and is a serious condition).Normally, mammals lose the ability to digest lactose shortly after entering childhood (in humans, somewhere between 3 and 5). However, a mutation in certain human populations somewhere around 20,000 BCE enabled those people to continue to consume milk for their entire life. So, in reality, "lactose tolerance" is the genetic aberration (though, a beneficial one).
it eats and digest it all
2-3 eight ounce glasses everyday.
