I envision a future where I can eat as much sugar without being as risk for various diseases. I dont think I could ever give up on sugar to even a healthy limit. I know it's bad but to me, enjoying desserts is a big part of my life. I know the risks of eating too much sugar (ex: obesity, type 2 diabetes, etc) but that doesn't stop me from my tea time sessions when I eat some dessert with tea to balance it out and it doesn't stop my friends and I from going out to get desserts after eating a meal. Unless sugar is later determined as a drug, I don't think I will be able to decrease my sugar intake.
Therefore, I think a solution could be to make a law that declares sugar to be a drug and allow people to only buy it in very limited amounts like over the counter drugs, or not at all.
