Peels, stalks and seeds could close the fibre gap, study suggests

King's College London researchers say fruit and vegetable scraps are an overlooked fibre source, as only 4% of UK adults meet the 30g daily target. Analysing 12 foods, they found butternut squash skin and seeds hold 9.25g of fibre per 100g, while pineapple skin and core pack five times more than the flesh. Experts advise washing produce thoroughly first.
