Also when I do not eat sweets and junk for a few months your taste changes and can feel stuff you could not feel before. Once after a few month I ate one bag of small chips and almost puked from it how it tasted then after my taste "cleared".
Simple sugar is really more poisonous and addictive than some of the banned drugs, but the problem is that the most people do not think that way and most people know next to nothing about foods which is sad. Also when you go in to the shop there is almost not one thing without sugar in it, food industry is sick today, excpecially in USA where they are using high fructose corn syrup in every item they produce.
