I think suger is more dangerous than fat. I don't think the dangers of sugar are well known as the number of zero-calorie and zero-fat products is increasing. However, sugar does a lot of damage to the brain. It may also melt our teeth. In addition, sugar is highly addictive, and once you ingest a large amount of sugar, your body will start to seek sugar, and sugar that initially felt sweet will gradually become less sweet. Therefore, it becomes a vicious cycle of ingesting more sugar. So I think sugar is worse than other substances such as fat.
