The report makes no mention of those who consume “high fat”, or regular milk. There’s a lot of evidence that regular milk is better for you which is often given anecdotal support by the fact that farmers feed low fat milk (which makes it high in milk sugars) to fatten pigs, which is just as you would expect given the dangers of too many carbohydrates.
I had the same question.
What is 'regular milk' depends on your perspective.
From a rural perspective, skim milk is 'regular milk'. After you milked the cow, you let the cream rise and poured it off to make butter, leaving 'regular milk'. Also sometimes called 'fresh milk'. Only recently has homogenized whole milk become 'regular milk'.
Just showing my age, not criticizing. :-)
