Among the studies leading to a pendulum shift in how we view full-fat yogurt and cheese is a 2018 investigation in the
Another study in the journal Circulation discovered those who had higher circulating blood levels of fats associated with dairy intake, on average, had a 46 percent lower risk of developing diabetes over a 15-year period than those with lower levels. More good news for blue cheese lovers: A recent
And despite the extra calories it introduces, the fat in dairy may help, not hurt, in the battle against the bulge. A
The studies don't answer the question of why eating richer dairy products may be less hazardous than once thought. But there are several theories. "Whole fat dairy contains various types of fat and some are less problematic than others," says
Some of the negative effects of dairy saturated fat might be neutralized when eaten as part of the complex "food matrix" formed by dairy foods. Whole milk dairy foods are more than vehicles for fat. "Calcium, vitamin D and potassium are three prevalent nutrients in milk that most Americans don't get enough of," notes Salge Blake. Certain dairy foods, like yogurt, kefir and aged cheese, are fermented, meaning they supply beneficial microbes that may help in the battle against certain diseases. And there are those who would argue that if someone is choosing to skip whole-fat dairy in favor of low-fat or fat-free versions that are full of added sugars, they're hardly better off. It is important to study the effect of food as a whole and not just its specific nutrients.
In the battle of the bulge, higher fat dairy may have more immediate calories, but if they boost satiety through slower digestion and improved taste and texture satisfaction in the end overall daily calorie intake might be slashed resulting in slimmer waistlines.
But just because there's evidence against dairy fat being a health villain, it doesn't mean you shouldn't attempt to exercise restraint instead of smearing butter on everything. "People should still follow guidelines of limiting overall saturated fat intake to 10 percent of total calories," advises Salge Blake. And that is hard to do when you drown your cereal in whole milk and reach for a second serving of glistening pizza. Keep in mind that a number of large studies continue to show that replacing some of the saturated fat in a typical American diet from sources like dairy and meat with unsaturated sources is strongly linked to better long-term health. So while full-fat dairy may be compatible with a heart-healthy diet, there are other fatty foods that may contribute more strongly to longevity, such as fish, seeds, nuts and olive oil.
So, how to proceed? The body of data that is starting to show the need for you to drop only lesser fat dairy products in your shopping cart has reached its expiration date. So if you prefer to spoon up full-fat yogurt or nibble on quality aged cheese as part of your recommended three dairy servings a day, go ahead. But only do so with an eye on portions and what else you're eating. "If you're going to include full-fat dairy products in your diet you should balance things out by eating other foods like fish and legumes that are lower in calories and saturated fat," Salge Blake says. Eating too much full fat dairy that comes bundled with sugar, refined carbohydrates, and other saturated fats, as with ice cream, pizza and fast food, is bound to backfire.
