Researchers at King's College London found that peels, skins, seeds and stalks contained more dietary fiber than commonly eaten parts in 10 of 12 fresh produce types tested, according to a study in the International Journal of Food Sciences and Nutrition. The produce included butternut squash, bell peppers, broccoli, kiwi fruit, pineapple and watermelon; discarded parts made up 25% to 48% of each item's weight. Only 4% of UK adults meet the recommended 30 grams of fiber a day, and the lab study tested a limited range of foods.

00:00The parts of fruits and vegetables we throw away may be the most fiber-rich.
00:04Researchers at King's College London tested 12 common types of fresh produce.
00:09They included butternut squash, bell peppers, broccoli, kiwi, pineapple, and watermelon.
00:14In 10 of the 12, peels, skins, seeds, and stalks held more fiber than the eaten parts.
00:20Those discarded parts made up between 25% and 48% of each item's weight.
00:26That matters, because most people don't get enough fiber.
00:30In the UK, only 4% of adults hit the recommended 30 grams a day.
00:34Fiber is linked to better digestion and lower risk of type 2 diabetes and heart disease.
00:40The team stresses this isn't about eating squash skins by the bowl full.
00:44Instead, they'd like caterers and food makers to use more of each plant.
00:48Still, the scraps in the bin may be a missed source of fiber.
