WHY STICK WITH MILK?
Why would someone continue with a staple diet of milk only? Simple. Milk is easily and quickly swallowed. Meat, on the other hand, is much more substantial. It needs to be chewed, savored and broken down before it can be swallowed. Usually, we have to wait for it to cook. Sometimes, we even have to gnaw it off the bone or cut out some of the fat and gristle, and that is too much for us.
Even when we have learned and are willing to invest the extra effort this takes, we need to gradually allow our digestive systems to get used to this different and more complex diet. It might not all digest completely or as well as we like at first. And, then, there are a varieties of meat to get used to eating and digesting.
