Relatively low in fat, Christmas pud provides a good dose of fibre, B vitamins, potassium (good for lowering blood pressure), iron, calcium and antioxidants, thanks to the high content of dried fruit. But there are 300 calories per average 3oz serving, as well as 6.1g of fat, and those totals rise when your dish is covered in cream, custard or brandy butter. Have a small helping and savour every mouthful. Recommended helping: a 3oz/85g serving, containing 275 kcal and 6.1g fat.
