Whole milk comprises almost all the nutrient our body needs in a day. It has lots of calcium and vitamin D that is really good for the bone. Whole milk also keep us fulfilled and might help with weight control. However, humans are the only species that drink other species milk after adolescence, which explain why some people has problem digesting cow's milk and cause sensitivity in some people. The industrial process of cow's milk nowadays also inject hormones into the cows to make it possible to provide us milk all year round. These are the downside of consuming cow's milk which personally I didn't stop drinking cow's milk completely, but I've tried to avoid it as much as I can because I found that whole milk is the reason that cause me acne and mild indigestion.
