Eat meat, it is better for you, especially your teeth

I knew I was right all along, eating meat is far better for you than following the rubbish food pyramid, especially for your teeth:

Prehistoric humans didn’t have toothbrushes. They didn’t have floss or toothpaste, and they certainly didn’t have Listerine. Yet somehow, their mouths were a lot healthier than ours are today.

“Hunter-gatherers had really good teeth,” says?Alan Cooper, director of the Australian Centre for Ancient DNA. “[But] as soon as you get to farming populations, you see this massive change. Huge amounts of gum disease. And cavities start cropping up.”

And thousands of years later, we’re still waging, and often losing, our war against?oral disease.

Our changing diets are largely to blame.?

In a?study?published in the latest?Nature Genetics,?Cooper and his research team looked at calcified plaque on ancient teeth from 34 prehistoric human skeletons. What they found was that as our diets changed over time ? shifting from meat, vegetables and nuts to carbohydrates and sugar ? so too did the composition of bacteria in our mouths.

Not all oral bacteria are bad. In fact, many of these microbes help us by protecting against more dangerous pathogens.

However, the researchers found that as prehistoric humans transitioned from hunting and gathering to farming, certain types of disease-causing bacteria that were particularly efficient at using carbohydrates started to win out over other types of “friendly” bacteria in human mouths. The addition of processed flour and sugar during the Industrial Revolution only made matters worse.

Which is all very boring…when what he should have said was eat more meat:

“We brush our teeth and we floss, and we think that we’ve got good oral hygiene. But [we’re] completely failing to deal with the underlying problem,” he says. “Ten years from now, I think we’re going to find that the whole microbiome is a key part of what you get monitored for and treated for.”

As for right now, Cooper suggests that one way to help return your microbiome to a healthier, more balanced state might be to cut out all of those processed carbs and start eating like our ancestors.

Sounds like he’s another fan of the?paleo diet.
