Turn-IP for the books: With sales of swede turnip in Tesco stores across Ireland this year up 5% compared to this time last year, more and more people are recognizing the all-round health benefits of the root vegetable. A great source of vitamin B, it has high fibre levels, significant calcium levels for healthy bones, reduces cholesterol, supports cardiovascular health and is a great addition to an effective weight loss program due to its low calorie count. Tesco has already sold 1.5million swede turnips so far this year.Pictured harvesting turnips in Rush is Sarah Leonard,Tesco Produce Quality Manager.
