It would appear, accordingly, that some of the saturated fatty acids in milk have neutral or even positive effects on health. In contrast to this, the saturated fatty acids lauric-,myristic-(14:0) and palmitic (16:0) acid have low-density lipoprotein (LDL)- and high-density lipoprotein-(HDL) cholesterol-increasing properties. High intake of these acids raises blood cholesterol levels, and diets rich in saturated fat have been regarded to contribute to development of heart diseases, weight gain and obesity. Association between consumption of milk and milk products and serum total cholesterol, LDL cholesterol and HDL cholesterol has been reported . High cholesterol levels are a risk factor for coronary heart disease (CHD),with LDL cholesterol and a high ratio between LDL and HDL cholesterol enhancing the risk of CHD.
