Nowadays, the great number of people, especially young people, like ordering meals online. It’s not surprised. First, as the pace of modern life is becoming faster and faster, people had less time to cook even one meal for themselves. Second, the development of technology bring us smart phones and new apps, what may lead to the increase in online service. However, we should pay more attention to food. As we all know it, our health is closely related to what we eat. Although the service provides us convenience, we must take the food safety to consideration. Home-made food is cleaner and healthier, but I prefer to cook food at home rather than ordering meals online.
