Hence, like you said, it's so important to get a diversity because you want both mechanisms of action.

But then once in your stomach, both the soluble and insoluble cause a bit of a swelling of the tummy.

These stretch receptors in your tummy feed back to your brain and say, hey, you're full.

You don't need to eat any more food, which for most of us is a good thing in the food environment we live in.

Then when it enters the small intestine, which is where your stomach empties the food into, the soluble fibers particularly form a gel-like membrane.

substance and so it's quite thick so what that does is it slows down the rate that your food is passing through your gastrointestinal tract slows down the rate it's passing through your small intestine why is that important well it's important for a number of reasons it means firstly assuming you're eating that fiber with other foods which is how you should be eating it so you're consuming as part of a food that will have carbohydrates in might have sugar in so fruit for example

It will delay the rate at which you're absorbing the sugar, so the glucose into your bloodstream.

So you'll get a lovely kind of blunted, natural, normal peak in blood glucose, blood sugar that your body handles then very well.

The other thing that happens that I think is really exciting, you also absorb it slightly lower down your gastrointestinal tract.

It's passing more slowly.

It's not absorbed rapidly at the top, the other bits of the food.

And what that means is you have more of these fullness receptors.

So like GLP receptors, most people have heard of GLP, you know, your kind of fullness hormone.

And so it's therefore activating more of these receptors because the fiber is allowing it to be digested lower down your gastrointestinal tract.

So again, it's feeding back saying, oh, whoa, whoa, whoa, you're full.

And then the magic happens as well in the large intestine, in the colon, like we've just discussed.

So you have all of this wonderful soluble fiber that the gut microbes feed on.

So in the UK, our guidelines are 30 grams of fiber a day.

In the US, they give a recommendation based on how many calories you consume.

So they say 14 grams per 1,000 calories.
