Soluble fibre may improve glucose control

About a tablespoon of a supplement would help people with type 2 diabetes, says researcher

People with type 2 diabetes who take soluble fibre supplements have slightly lower blood sugar than their peers who don't add this type of fibre to their diets, a research review has found.

Researchers focused on supplements containing viscous fibre — a type of soluble fibre that forms a thick gel when mixed with water.

Foods such as legumes, asparagus, oats and flax contain viscous fibre; supplements with this type of fibre include guar gum, psyllium and pectin.

To examine the connection between viscous fibre supplements and blood sugar, researchers examined data from 28 clinical trials with almost 1400 participants with type 2 diabetes.

People were randomly chosen to take viscous fibre supplements, other types of supplements without viscous fibre or no supplements at all.

Most trials in the study focused on haemoglobin A1c levels.
