Safety of milk
Cow milk is safe! depending on your age, you can chose to use regular milk with full fat content ( about 3%), 2% (only 1% less, not 98% less as people may think), 1% or non-fat.
Non fat tastes like water! if you are old enough, like 40 years or older, and drink full fat regular milk, it is just like you drink non-fat milk and add a bid spoon of butter onto it. That is where the danger is!
