Researchers Urge Consumption of Fruit and Vegetable Scraps to Boost Fiber Intake

OPA WIRE, Nov 1 (OPA) — A study conducted by researchers at King's College London analyzed 12 raw fruits and vegetables, including broccoli, kiwi, pineapple, and pumpkin. The findings indicate that many discarded parts, such as peels, seeds, and stems, offer significant nutritional value. For instance, kiwi consumed with its skin provides 50 percent more fiber than peeled fruit, while pineapple cores contain five times the fiber of the flesh.

Official data reveals that only four percent of adults meet the recommended daily intake of 30 grams of fiber, a nutrient essential for digestive health and linked to reduced risks of heart disease and bowel cancer. Dr. Rachel Gibson, who led the project, noted that discarding these parts represents both a nutritional and financial loss for consumers. The research team suggests incorporating these scraps into meals through techniques like blending, steaming, or stir-frying.

During a nine-week trial at the university's canteen, "root-to-tip" dishes accounted for one-third of daily hot meal sales. While some participants expressed hesitation, the initiative demonstrated that these ingredients can be integrated into standard diets. Kirsten Jackson, a dietitian with the British Dietetic Association, emphasized that while these methods are effective, produce must be thoroughly washed, and fiber intake should be increased gradually to avoid digestive discomfort.

Health experts advise caution regarding certain items, noting that green potatoes and rhubarb leaves contain toxic compounds. Furthermore, hard stems and seeds may pose choking hazards for young children. The British Nutrition Foundation supports the shift toward reducing food waste but stresses that individuals should prioritize safety and preparation methods that make tougher textures palatable, such as finely chopping or freezing stems for later use in soups or stir-fries.
