Is "fibermaxxing" the next big wellness trend, or is it simply an old nutrition lesson with a new name?

You've probably seen the word fibermaxxing popping up online, with people adding enormous amounts of fibre to their diets in the name of better digestion, weight management, blood sugar control, and gut health.

But here's the thing: the importance of dietary fibre isn't new.

In this episode, we take a closer look at the science behind fibre and separate the genuinely beneficial advice from the social-media hype.

We'll explore what fibre actually does in the body, the different types of fibre, its relationship with digestive health and overall health, and whether you can actually have too much of a good thing.

We will also talk about how to increase your fibre intake without spending a fortune on supplements, powders, and gummies.

From oats to callaloo, you may already have some excellent sources of fibre in your kitchen.
