Answer:

With the social economy developing at an amazing pace, our life become better and better. The food, providing us more choices, is one of the most vital developments of our life. Some people think food is healthier in the past, yet some people believe that food is better nowadays. Personally, I think the modern food is healthier than the past.
Admittedly, food has its benefit in the past. Obviously, food, including vegetables and meat, is more natural than meat from the natural environment than today. In addition, there is a fewer proportion of oil, which makes people become fat, in the food in the past. In contrast, there are too many junk foods today, causing us over-weight, unhealthy and unsafe. In fact, the KFC and the MacDonald’s, attracting many children, become a main problem that has a negative effect of children's health. For instance, children in the past were stronger and had a better healthy condition than today. As a result, a lot of parents nowadays ban their child from eating junk food.
However, there are various kinds of food supplied nowadays, which provide us all kinds of nutrition that we need every day. Every kind of food has its own nutrition. There are lots of experimental data shows that tomatoes and lemons contain a great number of Vitamin C that cannot fail to promote human's ability to protect the disease in its fruit. Besides, the milk has lots of proteins, helping us to have a stronger body and unbreakable skeletons. The food kinds are simple, however, which cannot reach the amount of demand of our body acquirement everyday. In other words, we cannot fail to afford the milk or meat everyday, which have benefit on our health.
In addition, we presently have more options of healthy compositions within a meal and more wholesome matching of various vegetables and meats, which strikes a perfect balance between different kinds of nutrition. With the economy developing at an amazing pace, people pay more attention to the collocation of foods. There is a possibility that we can eat vegetables and meat at lunch or dinner everyday. In the past, however, people only have one type of food when they have lunch and dinner. It is a significant change that we can gain all kinds of nutrition by food collocation. Besides, modern technology makes foods more nutrient. For example, the milk has more proteins, and it is added with lots of CA, which is a chemical atom that good for our skeleton development. Under this circumstance, the foods cannot fail to stimulate our body development with efficiency.
In summary, judging from the discussion offered above, I could safely arrive at the conclusion that I think the modern food is healthier than the past because of the foods have various choices and have a better collocation in everyday eating diet.
