Hello and welcome to Sigma Nutrition Radio. You are very welcome to the show. My name is Danny Lennon.

And today we're going to be talking all about dietary fiber and hearing from several experts in this area to try and give us an understanding of what we know about dietary fiber intakes, where we might see benefit, and then where

that leaves us in terms of determining what is the amount of dietary fiber, we should ideally

be consuming if we want to be healthy and to reduce chronic disease risk.

So this is going to span from looking at certain claims that people make about fiber not

being important, not being essential,

and therefore we don't need any, looking at what the evidence says about those claims,

then looking at some of both the epidemiology as well as control feeding trials relating to

fiber intakes and looking at low intakes, high intakes, and then starting to see what type

of dose response that we get

for different outcomes. And so we will look at those outcomes like cardiovascular disease, like

type 2 diabetes, like cancer risk, and try and see what do we know about doses of fiber that

confer a greater degree of risk reduction. And then ultimately try and tie this

all together to see, okay, if we are going for that maximal risk reduction, what is an amount

of dietary fiber that we should be aiming for? Where do recommendations currently lie? And

where do these recommendations come from? And so hopefully by the end of this episode,

you will have a really strong understanding of much of the evidence base relating to

dietary fiber and chronic disease risk. Like I mentioned, you're going to hear from six

different experts who have previously been on this podcast. And so if you want to go and listen

to their appearances on this show, I will put a list of those

in the episode page.
