Nutritional scientist Tim Spector has revealed a valuable ‘superfood’ tip that can have significant health benefits. Professor Spector, renowned for his work in genetic epidemiology at King’s College London and as the founder of the Zoe health app, urged people not to discard fruit and vegetable peels. He highlighted that these peels are rich in chemical polyphenols, which are incredibly beneficial for health. They aid in improving stomach microbiome health, reducing inflammation, and potentially lowering the risk of conditions like dementia, arthritis, and diabetes. Moreover, fruit and vegetable peels often contain higher amounts of vitamin C, which can help in reducing blood pressure, heart disease, and dementia.
Additionally, these peels are a great source of fibre, and increasing fibre intake can significantly reduce cholesterol levels. Professor Spector emphasized that consuming just 5g more fibre a day can have a greater impact on reducing blood pressure than cutting down on salt intake. By retaining the skin of fruits and vegetables, individuals can benefit from increased fibre content and higher levels of essential nutrients like vitamin C.
For instance, leaving the skin on while roasting vegetables like butternut squash not only streamlines preparation and reduces food waste but also enhances the fibre and vitamin content of the dish. If a recipe calls for peeling, Professor Spector suggested a clever hack shared by a friend to turn peels into vegetable chips by baking them with olive oil, salt, and pepper. He highlighted the importance of minimising food waste and making choices that support healthier eating habits while also being mindful of environmental impact.
With approximately one-third of all food globally being lost or wasted, incorporating simple hacks like utilising peels for added nutrition can not only benefit individual health but also contribute to reducing food waste on a larger scale. Professor Spector’s advice underscores the significance of making informed choices when it comes to food preparation and consumption, promoting both personal well-being and sustainability.
