Japanese convenience stores use induction to heat food without vitamins escaping
While standard microwaves destroy nearly eighty percent of a meal's nutrients, these high-tech ovens use magnetic fields to keep vitamins locked inside your midnight snack.

By heating the food evenly and rapidly from the outside in, these machines preserve up to 95% of the original nutrient content.
