And the next big idea that's really important is the end officially of the low-fat era.

Even in the last guidelines, they said we shouldn't worry about fat, but they said eat low-fat dairy.

We also have quietly kind of retreated from this fear around saturated fat.

Still personalized, it's important.

I think that there was some nuances that they didn't quite get right.

But bottom line is that we shouldn't fear saturated fat so much.

And that the science shows that full fat dairy is linked to neutral or even metabolic consequences that are better.

In fact, there was a great article published through Tufts and Darius Mazzafarian entitled, Is Butter Back?

And it showed that actually it was neutral in terms of cardiovascular disease and it was beneficial in terms of diabetes.
