The protein in dairy products has long been thought to be the primary driver of health benefits, but it’s not always easy to determine how much protein is actually there in dairy.

That’s where researchers at the University of Pennsylvania and the University at Buffalo have been able to use a new analysis tool to do just that.

The team found that the amount of protein in milk, a staple of the Western diet, varies from dairy cow to dairy cow.

But they found that milk from cows that were farmed in conditions that boost the growth of the milk cow, including high temperatures and large areas of pasture, did slightly more protein than milk from animals that were raised on less intensive farming practices.

They say their results indicate that dairy cows need to be raised on a more consistent diet to reap the benefits of milk protein.
