Sugar is one of those things that nearly everyone has a taste for and it is not at all our faults. For many reasons, sugar is appealing to humans. Primary among these is the fact that humans have evolved to use glucose as our main source of energy. That means when we are trying to survive, we will try to get as much quick energy as we can in the form of glucose (predominantly fruits in the wild). Because of this, we have mutated to develop a taste for sugar because those who enjoyed it probably survived longer and more robustly.
For evolutionary reasons, we are thus predisposed to loving sugar and eating a lot of it when we can. The only problem is that today’s food environment is nothing like what it once was. We no longer have to forage and hunt for our food and we are definitely not struggling or fasting for nearly as long as we used to. That means we are eating all the sugar we want in order to fill our needs, but we are going about it in a completely incorrect manner.
Most of the time, it is impossible for us to control our urges unless we have a lot of willpower, which can sometimes be more than we would like to handle. Willpower is a fickle thing and many people can’t stand to go very long without eating sugar. Going forward, knowing that it is an old trait and does not necessarily need to have sway over your life can be a really big motivating factor for you to avoid sugar altogether. In most situations, it is possible to get rid of sugar and at the same time still lead a happy lifestyle.
