NEW YORK – Since the 1980s, federal health officials have urged Americans to opt for lower-fat dairy products, such as skim milk and reduced-fat yogurt, over full-fat versions.

Health experts have long recommended avoiding full-fat dairy because it is high in saturated fats which, in excess, can raise cholesterol and the risk for heart disease. It is also higher in calories than reduced-fat versions, potentially increasing the chances of gaining weight or developing obesity.
