This is episode 52 of Sigma Nutrition Radio. Thank you so much for taking the time to listen to the show today.

0:08.5

I'm going to talk a bit about dietary fiber. And this is a kind of shout out to one of our listeners,

0:14.6

Colin Matthews, who gave me the suggestion as a topic for the show. And I think it's worth covering for a number of reasons.

0:21.9

Now, because there are a few different areas

0:24.6

that I'd like to explore on this topic,

0:26.6

and as some of you may know,

0:28.5

I hate being overly brief

0:30.5

for fear of leaving out something important or useful,

type 2 diabetes, and then a host of other chronic illnesses usually related to the gut.

1:27.3

So when we're talking about fiber,

1:29.2

we're basically talking about a type of carbohydrate that resists digestion.

1:34.8

So say we take in some dietary carbohydrate,

1:38.4

then that will usually get down to the small intestine

1:41.2

where we digest it, use it, take the calories from it and create energy.

1:45.8

Now with fiber, because it resists digestion, it gets past the small intestine and makes its way down to the large intestine.

1:54.7

And there it can go one of two ways.
