PHILADELPHIA (CBS) — Do you drink a latte or eat cereal in the morning? If so, you’ll want to read this new study.

Researchers say full fat dairy, like whole milk, may actually be better for you than skim milk.

They found that adults with high levels of full-fat dairy byproducts in their blood had a lower risk of developing diabetes.

It is not clear why, but experts say consuming high-fat foods keeps you fuller longer, so you may eat fewer calories overall each day.

“I think these findings together with those from other studies do call for a change in the policy of recommending only low-fat dairy products,” Dr. Dariush Mozaffarian tells Time.

“There is no prospective human evidence that people who eat low-fat dairy do better than people who eat whole-fat dairy.”
