Another flavour available is Apple & Cinnamon, also part of the guilt free snacking range.
Each bar is only 91 calories. Most of the sugars present will be from natural from the dried fruit. Fats are also very low only counting for 3.7% of your GDA. Since the bar is small you don't really get much fibre or protein. The bar contains a prebiotic - Fructose-Oligosaccharide - this helps to increase the numbers of good bacteria in the gut.
