Sugar

There are many types of sugar, the most common being white granulated. The only one to have any nutritional value is raw cane sugar - but even this has only a trace of natural minerals, so it can hardly be considered a useful part of the diet. Where castor/superfine sugar is required in the recipes, it is possible to make your own by whizzing granulated sugar in a blender until it is in very small crystals, not a powder. However, all sugars are cariogenic, and therefore best avoided.
