Potatoes mainly have carbs and moderate amounts of protein and fibre, but no fats, says Rawan Al Ashkar, specialist clinical dietitian at Medcare hospital. They are a good source of several vitamins and minerals, including potassium, vitamin C and folate, and provide some healthy antioxidants.
‘Potatoes contain some minerals and plant compounds that help lower blood pressure and reduce the risk of heart disease,’ she adds. ‘The iron, phosphorous, calcium, magnesium and zinc in potatoes help the body to build and maintain bone structure and strength. But they have high levels of carbs, so are not beneficial for people with diabetes or obesity when eaten in excess.’
