My theory was that it was because at some point in evolution, not long ago, our ancestors, like most species that still exist, created vitamin C out of glucose. In other words, it was the important need to get our vitamin C that made us like the taste of glucose.
If the MEDICAL MEDIUM information is real, then the reason sugar tastes so good is because it is the most important of all nutrients (outside oxygen)! So the new revised theory is that over the course of evolution, when carbohydrate food was scarce, e.g. during the winter when only fats/meats were available, and the body had to make a choice; either use some of its vital glucose fuel to make vitamin C, or survive on the little available vitamin C in the diet, the need for glucose trumped!
This revelation makes me realize that we can now have our cake and eat it too!
We can enjoy sweets
(...just not the highly refined sweets, and we need to especially avoid eating sweets with fats.)
