Nowadays, food has become easier to prepare. Has this change improved the way people live?

Most of the time when we think about easier foot we think in preheating food or fast food. We can see that this type of food sometimes is not healthy, as an example we can take U.S.A and their obesity rate, more than 70 percent of Americans suffers of this situation and not only north-American, fast food has become a health danger for everybody and a concern for doctors worldwide.

On the other hand we also have some healthy food such a vegetarian that they are easier to make. The problem is that this type of food does not attract much people like fast or preheating food does.

In conclusion besides that food has become easier and faster to prepare has not improve the way we live, on the contrary it has become a time bomb for our health
