Should we enrich or modify our food?

I believe food should be modified because people need calcium, vitamin A, and so on in order to be healthy efficient human beings. People who do not get enough calcium have long term complications such as low bone mass. As well as people who do not get enough vitamin A in their diet suffer from weak membranes around their organs making them vulnerable to diseases. Although some people know how to find nutrition in foods naturally such as milk, vegetables, bread, grain, fish etc. other people might not have the resources or knowledge to make such decisions. Which is why food should be modified to make sure everyone gets the necessary amount of vitamins and calcium they need.
