Dietary fibre is one of the most consistently health-supportive components of the diet across the research literature. As a nutrition professional, 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 sugar. 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

Fibre Content of Common Foods (per 100 g)

Chia seeds 34 g Oats (dry) 10 g Lentils (cooked) 8 g Broccoli 3 g Apple (with skin) 2.4 g
