Do you melt at the creaminess of full-fat yogurt? Well, chances are you’ve been told to resist the temptation if you’re on a diet. The reason behind this seems pretty straightforward: The extra calories packed into the fat are bad for our waistlines.

But what if dairy fat isn’t the dietary evil we believe it is? In fact, two recent studies have concluded that the consumption of whole-fat dairy is linked to reduced body fat.

In one paper, published by Swedish researchers in Scandinavian Journal of Primary Health Care, middle-aged men who consumed high-fat milk, butter and cream were significantly less likely to become too fat over a period of 12 years compared with men who never or rarely ate high-fat dairy.

The second study, published in the European Journal of Nutrition, is an analysis of 16 other studies. There has been an assumption that high-fat dairy foods contribute to overweight, but the reviewers concluded that the evidence does not support this assumption. In fact, the reviewers found that in most of the studies, high-fat dairy was associated with a lower risk of overweight.

It’s not clear what might explain this phenomenon. Some researchers point to the satiety (饱腹感) factor. The higher levels of fat in whole milk products may make us feel fuller, faster. And as a result, the thinking goes, we may end up eating less.

Or the explanation could be more complex. “There may be bioactive substances in the milk fat that may be altering our metabolism (新陈代谢) in a way that helps us use the fat and burn it for energy, rather than storing it in our bodies,” says Greg Miller, executive vice president of America’s National Dairy Council.

Whatever the mechanism, this association between higher dairy fat and lower body weight appears to hold up in children, too. And in addition to the body weight association, whole milk contains beneficial omega3 fatty acids.

However, some people should still avoid consuming too much whole-milk dairy products. These products are relatively high in saturated fat (饱和脂肪), and eating too much saturated fat can increase the risk of heart disease. So many experts agree that adults with high cholesterol (胆固醇) should continue to limit dairy fat.
