Processed or refined sugar has been a staple of the modern lifestyle for hundreds of years now, first rising to prominence during the height of the British Empire. It has played a massive role in diets ever since, and has only increased in usage.
Refined table sugar has a number of disadvantages over naturally occurring sugars. For instance, as part of the processing of the refined sugar all of the nutrients of the sugar is taken out, leaving you with sugar in its pure form, only valued as a carbohydrate.
Meanwhile, naturally occurring sugars, which can be found in every fruit and a number of vegetables, contain all of the other benefits of their host, whether that be from a strawberry, banana, or orange. This also improves the likelihood of not over-consuming sugar, which is a situation which is all too common for consumers of refined table sugar.
