What Is the Blood Sugar Roller Coaster?

People always tell me about their sugar highs and their sugar crashes. What is meant by that? If you could just explain to people about the whole blood sugar roller coaster thing. So if we're going to have a chocolate bar or a fizzy drink or an energy drink, you're essentially having a high increase in glucose levels. And what ends up happening, that increase, the body needs to regulate it. It can't leave you with such high levels of sugar because it's not healthy. Particularly with people with pre-diabetes or have diabetes, that can be quite dangerous.
