Dietary fibre is one of the most consistently health-supportive components of the diet across the research literature. From an informational perspective, adequate fibre intake is among the highest-impact dietary changes most people can make. This guide explains what fibre is, what the different types do, and how to increase yours without digestive discomfort. Additionally, exploring a gluten and wheat free diet plan is a great way to accelerate your results.
Soluble vs Insoluble Fibre: What’s the Difference?
Soluble Fibre
Dissolves in water to form a viscous gel. Slows digestion, lowers LDL cholesterol, stabilises blood glucose. You might also find it highly effective to integrate a best sleep recovery supplement into your overall routine.
Sources: Oats, barley, lentils, chickpeas, apples, citrus, psyllium husk
Insoluble Fibre
Doesn’t dissolve. Adds bulk to stool, speeds intestinal transit, supports bowel regularity.
Sources: Wheat bran, wholegrains, vegetable skins, nuts, seeds, celery
