About this Resource
Dietary fibre is a type of undigestible, complex carbohydrate that has considerable evidence supporting its health benefits. Most health authorities (e.g., USDA, NHS) recommend fibre intakes should be at least 30 g per day. The average global intake is 20 g per day (or lower), meaning that most people should be getting around 50% more fibre every day.
Grounded in the Research
Despite a wealth of evidence generated over many decades to corroborate the multiple health benefits of dietary fibre, the health risks of a diet that lacks fibre and the corresponding efforts to provide public health messages to educate the populace, sadly, within the Western world, our diets remain lacking in fibre.
