What creates optimal microbiota?
What about fiber? How much do we need? What are the origins of the idea that it is good for us. What are the guidelines? What is the totality of the evidence? What are the claimed mechanisms by which fiber could be of benefit? When did all of this start?
In this presentation from the Low Carb Denver 2019 conference, Dr. Zoë Harcombe walks us through the history of fiber.Watch a part of the presentation above. The full video is available (with captions and transcript) with a free trial or membership:
What about fiber? — Dr. Zoë Harcombe
Transcript from preview above
Dr. Zoë Harcombe: This is becoming bigger and bigger, it’s about the gut microbiome, the microbiota in our gut and they say that that is the important thing, fiber feed on that and that’s why it’s so important. So I’m just going to do one slide on that one.
What creates optimal microbiota? There’s certain things that we should do and certain things that we shouldn’t do. First of all, choose healthy parents, these two look pretty good, especially mom. Make sure mom’s looking super healthy.
Make sure mom then gives you birth properly because that’s how she gives you all of her healthy gut flora. Make sure she then breastfeeds you, don’t take antibiotics unless your life depends on it especially as a child, but also as an adult, antacids are really not good either, do eat good real stuff and don’t eat junk.
We do know from studies that eating junk is really not good for your microbiome. And then there are foods that don’t contain fiber, but they are also fabulous for our gut flora. So, we’ve got things like caffeine, natural live yogurt, unpasteurized milk and cheese, beans on toast.
May I suggest that if you’ve got a fabulous gut microbiome, beans on toast it’s not going to make much difference and if you’ve got a dreadful microbiome, again beans on toast is not going to make much difference.
Now while we’re on beans there was a fabulous study in 1991 when they got 10 volunteers and they actually tried to measure the outputs in the form of flatulence from human beings. So obviously they didn’t give those human beings meat and that stuff.
They gave them 200 grams of beans a day and measured the emissions and the emissions included methane which I find hysterical, because the vegans are blaming the cows… and they’re the ones eating the beans, I kind of think that’s like blaming the dog when you’ve just farted.
