This doctor says eat your ice cream for a long, healthy life : NPR

So when he released his book, literally titled Eat Your Ice Cream: Six Simple Rules for a Long and Healthy Life, I asked him what motivated him.

"Mostly anger at the wellness industrial complex," Emanuel says. He says the wellness industry is selling people all kinds of things that are expensive and clinically unproven, pointing to the latest peptide trend, whole body scans and "all sorts of supplements" marketed as anti-aging elixirs.

And though the title is a bit tongue-in-cheek, he points to evidence that people who are in the habit of eating ice cream have a lower risk of metabolic disease, despite the fact that it has lots of sugar and fat. Researchers have dubbed this the "ice cream paradox." There's data from 2015 that suggests "that ice cream is actually pretty good at preventing development of Type 2 diabetes, and dairy in general is good at preventing Type 2 diabetes," Emanuel says.
