Where can I open a sugar-free food store?

As far as I know, sugar-free health industry is the trend in recent years. It is a branch of traditional snack food and a new industrial chain. At present, large supermarkets have sugar-free food counters, which are suitable for middle-aged and elderly people, diabetics, obese people and third-class people. Some pharmacies also have counters, so there is potential to open sugar-free food stores or diabetic food stores.
