They might think ah, milk with lots of creamy butter...
probably tastes good because of the butter but probably
very fattening. This couldn't be further from the truth.
There actually isn't any butter in buttermilk, per se.
Buttermilk is the liquid that is left after the butter has
been separated from the milk, often used for making breads.
Sometimes buttermilk is also made from cultured milk
by adding a bacteria to sweet milk. Different but a
little similar to yogurt.
Buttermilk has less fat than whole milk because the
fat has been removed. Due to buttermilk having more
lactic acid than even skim milk- it's often recommended for
people with digestive problems to drink
buttermilk rather than regular milk.
