2.0 · 1d ago · WORLD

The Facts

  • King's College London researchers analysed 12 raw fresh foods (beetroot, bell pepper, broccoli, butternut squash, cauliflower, celeriac, curly kale, fennel, kiwi, leek, pineapple, watermelon) and found many discarded parts contained more fibre than the parts usually eaten. BBC only
  • Watermelon rind contained 2.10g of fibre per 100g; butternut squash skin and seeds contained 9.25g per 100g; pineapple skin and core contained five times more fibre than the flesh; broccoli stalks contained slightly less fibre than florets. BBC only
  • Official figures show only 4% of UK adults meet the recommended 30g daily fibre intake. BBC only
  • In a nine-week canteen trial at the university, 'root-to-tip' dishes made up a third of total daily hot menu sales; diners choosing them were less likely to finish their meals than those eating from the conventional menu. BBC only
  • Dietitian Kirsten Jackson of the British Dietetic Association said the approach is useful if produce is washed thoroughly and fibre is increased gradually, and does not recommend tough pineapple skins. BBC only

Context

UK researchers at King's College London say fruit and vegetable scraps such as peels, stalks and cores are an overlooked source of dietary fibre. Project lead Dr Rachel Gibson said people are discarding a significant amount of fibre.

The college has served root-to-tip meals, including banana skin curry, in its canteen. Dietitians advise washing produce, increasing fibre gradually, and avoiding certain toxic parts.
