The lifestyle of food is changing rapidly

Today, the lifestyle of food is changing rapidly. Moreover, this makes children’s thoughts for the food worse and worse. What is the problem?
The main problem is having too many likes and dislikes for children in what they eat. Then, I expect that two main reasons cause this problem.
First, one can say the appearance of the fast-food shop and convenience store is part of the problem.
Second, it is how parents raised their children. Today, the breeding of parents seems to be short. Some parents have too much work and cannot prepare dishes for their children. As people can purchase many foods cheaper and easily because of the convenience store and fast food store, they come to use them. For example, the children who go to a crammer or have more time to be alone at home often eat a box lunch of a convenience store. As a result of this, the various bad influences; what they eat become fixed; the balance of nourishment gets out of shape and they can get ill.
Cooking homemade dishes is very important. Therefore, the main solution is making the time to cook a dish for the children. If their parents can do so, the cooking guidebook gives them many ideas and knowledge for solving the problem; changing the food’s shape or taste, for example.
In the future, the lifestyle will become more useful, but we have to be careful about our health. [240 words]
