Coined by nutritionist Sasha Watkins, Head of Health at Mindful Chef, fibre-layering takes the conversation beyond how much fibre and into how many kinds. Because not all fibre is the same, and variety matters just as much as quantity.
There are two main types of fibre your body needs:
Soluble fibre: found in oats, beans, lentils, chia seeds, apples, and bananas. It dissolves in water, slows digestion, and helps keep blood sugar steady.
Insoluble fibre: found in whole grains, nuts, spinach, kale, and brown rice. It adds bulk, keeps things moving, and supports a healthy gut.
Both are essential. And the science is catching up with this idea; a 2025 study from RMIT University found that fibre diversity (not just fibre quantity) is key to targeted health benefits, with different fibre types working very differently in the body.
Fibre-layering is grounded in the 30x30 principle: aiming for 30g of fibre a day by eating 30 different plant types per week. It's not about overhauling your diet overnight, it's about gently building variety into the meals you already love.
This feels very Just Live a Little to us. No extreme overhauls. No food guilt. Just a little more, every day.
