> Sucrose is a disaccharide, also known as a "double sugar," typically derived from cane or beets. Each molecule of sucrose is equivalent to one molecule of glucose and one molecule of fructose, however they are chemically bonded together at the molecular level, which is what gives sucrose its own definition as a sugar. When eaten, each molecule of sucrose must be broken down by the acids and enzymes in the digestive tract, resulting ultimately in pure glucose, which is what the body utilizes to transport the nutrition to each of its cells. Glucose is driving metabolic disease around the world. It's unfortunate that the dietary guidelines and HFCS are temporally coincidental, which just means we have to look more carefully for clues. One place we can look is the introduction of products like "Pepsi with real sugar" and "Mountain Dew Throwback" made with sucrose. I may have missed it, but I don't think we saw any decline in obesity associated with these products. We haven't seen any declines in obesity related to the explosion of artificial sweeteners and diet sodas either. There's a reason, and it's because at the population level we're still devouring more carbohydrates than ever. Carbohydrates are metabolized into glucose, regardless of the source. There is no such thing as "good sugar" or "good carbohydrates."
