You're listening to Bulletproof Radio with Dave Asprey.

Today's cool fact of the day is that the Guruage people in Ethiopia raised something called

Zeebu.

These are cattle that are mostly kept for their butter and the typical household has a huge

amount of spiced butter, aging, and clay pots that hang from the walls of their huts.

By the way, this would be like Disneyland for me.

And for this drive, butter is believed to be medicinal and the Guruage often take it

internally or they even use it as a lotion or a poultice.

And a proverb in that tribe says, a sickness that has the upper hand over butter is destined

for death.

They use different species of encente, or actually I'm probably saying that wrong,

a seat, which is commonly known as an Ethiopian banana, are also part of how they alleviate

illness because they would have a lot of fermentable fibers to feed healthy bacteria in the gut.

So it's kind of cool that you have a whole people who realize, oh, butter has interesting

stuff in it, probably mostly butyric acid and vitamin K2.

And you got to have some fermentable fiber.

And if you're all keto all the time, the way I certainly have experimented with when

I was riding the Bull of Proof Diet, I think there might be something to be said for having

some fermentable fibers so you have a healthy gut bacteria.

And you're not going to get that from one serving of vegetables a day or an all-meat diet.

When I tried that, I gave myself food allergies.

So I'm a huge fan of keto.
