Some people claim that the food we eat currently is correspondingly healthy. This argument seems reasonable. For example, a wide range of adults aged 65 years and older live a well-off life in the present society, which was scarce in 50 years earlier.

First, the living standards and the purchasing capacities have tremendously improved even for an average Joe. This is mainly because the soaring development of national economy makes it within our reach to own and obtain the categories of good foodstuff. Second, due to the research and development of science and technology ，there are continuously superior products with different flavors taken to market for us to select according to the strict procedures so that it can meet various demands. For example，the prevalent organic food is well accepted and eaten in the household.

However, although economic development can create the opportunities for people to have healthy food, too much nutrition and high fat will lead to some chronic disease，such as hypertension ，diabetes and obesity. According to a survey made in one high school in Beijing, more than 40% of students are overweight, which could potentially trigger various kinds of diseases.  Furthermore, maybe technology can discover more new type food to benefit our health ，but the supplements in the dietary can be added the chemistry elements which have notoriously side effects to human body. In contrast to those who eat the regular intake of a prescribed amount，the people who eat the toxin absolutely has less longevity ,about 10-15 years distance.

Also，the food in the past is never polluted, so it is much cleaner. According to a survey made by the specialists，the food in the past is the most purely natural and healthy to us，no pesticides，no carcinogen. In addition，the food production and processing is almost the  homemade in family. This is because it’s the tradition for the last generation to eat at home together when they do not need to eat out.

So it is self-evident that the food we eat in the past is much better than the food now.
