Are hormones good for our health?

For my research paper, I am going to look into how hormone-injected meat affects our health. So far, the main thing I'm seeing while researching is the comparison between Europe and the United States. Europe - or the European Union (EU) - cut hormone-injected meat out of their stores in 1985, and in 1989 they banned imported meat from the U.S. because of the way that we modify it. I'm still exploring all the information, but what I am trying to learn is if it is healthier to have non hormone-injected meat or not. I can do this by examining the health of European citizens and comparing/contrasting it to those of the United States. Obviously there will be other factors involved, but as a whole, I should get some sort of evidence proving whether it is or is not healthier.

Here is my annotated bibliography:

This article examines people from both he European Union and the United States and how they regard where their food comes from. It shows that people from Europe place a higher value on cattle that have not been fed with GMOs, and people from the US do not care as much. Also, the same goes for cattle that have been fed growth hormones, however, the beef that was not given growth hormones is almost indistinguishable from beef that was given growth hormones.

This article addresses the issue that there has not been much research on how growth-hormones affect the environment. The manure from the cattle who are given growth-hormones can effect the local fish in negative ways. The fish are exposed to androgenic hormones which is fatal to them. This article says that little is known about the effects of hormones on the environment and it says that there should be much more research before we continue to use them.

This article explains how farmers are trying to decrease costs, just as industrialists did, by cutting back on the quality and focusing on the quantity. It shows that cattle are fed with "feeding-stuff" to make them grow faster so that they can be slaughtered and sold with more of a profit. They use hexoestrol to decrease fat and increase bone and protein. This hormone can be harmful to human health, so the only way to ensure that a human will not consume it is if the farmer injects the hormone behind the ear and later makes sure the ear and it's near surroundings are destroyed.
