An efficient heater

Ever since it started being part of our lives, the microwave oven has helped us significantly. Its invention has certainly made our lives easier in the sense that now you can save time since you don’t need to be stirring your food every 10 or 20 seconds. It also can save money because you can reheat previously-cooked foods and you don’t need to throw them in the garbage. Now, think about how much it means to have a microwave oven to the people who can’t make it to their homes at lunch because they are at work, or even better, let’s think about ourselves: isn’t it great to have the opportunity to bring your own meal to college and being able to heat it up? Although you can buy a nice hot lunch, it is cheaper to bring your own food. Think about every time you have prepared a melted cheese sandwich, or heated up that delicious chocolate you drink in the mornings for breakfast. Sounds excellent to have such an efficient service, but is it always good to heat up food and other things in the microwave oven? Or do you think is better to just cook something every time you are hungry? By the way, does the microwave damage the nutrients in food?
