negative impact of reduced-fat dairy
The value of dairy is debatable, but I love it so I want to ensure that I am consuming it healthily. I recently ran across some information about it that was a bit surprising.
Dairy with its fat removed (low-fat or reduced fat) may not support the absorption and utilization of the fat soluble vitamins D and A, which are necessary for maintaining and laying down new bone mass. Thus, calcium may go primarily into soft tissue rather than into the bones in those who persist with reduced-fat dairy products.
Since one of the reasons often given for consuming dairy is providing vitamin D and calcium, consuming low-fat dairy defeats its own purpose.
If you are watching your fat intake, clearly you want to consume less dairy (I hope that was obvious).
