I grew up on a small mixed farm and remember lugging bottles of fresh milk into our neighbours' houses. Twenty five cents/quart. Mom always wanted one Jersey cow in the herd for the butterfat. When regulations came in prohibiting the sale of unpasteurized milk, we made butter for a few months until the herd was sold.
Later, I worked as a supervisor/spare driver for a dairy and was re-aquainting myself with a driver's home delivery route. As we rolled into one fellow's driveway, I got the litre of Homogenized and the litre of Blend which the old guy had gotten for years. The milk was for his tea. The blend was for his cereal. The driver stopped me and said the doctor had made the old guy cut back on his butterfat intake. So I put the blend back and got skim. Again I was corrected.
When the Doc had told the fellow to cut out butterfat in his milk, he figured skim for his tea was OK, but he still took blend for his cereal!
Look at it this way. Homogenized milk is 96% fat free.
