A brief google-fu tells me the it was first refined something like 2500 years ago, but was rare in the diet until sometime in the 1600s when it began to be refined commercially in the new world by the Portuguese on their plantations in Brazil.I'm assuming we are talking about refined sugar (the white sugar) and not natural sugar like honey. Sugar has been around for a long time but I'm not sure when refined sugar was invented. Most likely refined sugar was expensive so only certain people would actually have access to it.
In terms of refined sugar, the question would be, did kung fu schools have access to sugar in the first place. If they didn't have access to it, then they wouldn't have used it anyway. Considering that most of the world was poor. I can imagine gardens and farms being a big thing. If someone was to put us in a shack in the woods with a bag of seeds, we probably wouldn't be to concern with refining sugar. It may be better to just find some honey bees and save the honey and spend the rest of the time making sure that the crops grew. Refine sugar seems to be something that one would do if they had a lot of time on their hands.
Of course natural sugar like honey, or what occurs in fruit, would have been available to some extent. Would that stuff have been for the exclusive use of the elite? Perhaps.
But what I was hinting at was, it’s unlikely that kung fu people “thousands of years ago” would have had a high enough discretionary sugar content in their diet to distinguish its effects.
Let’s be real.
