Beer drinking= better health?

So i think i decided on my research topic. The other day I was searching through the data bases and found alot of information about how drinking beer is good for you. There is research that shows drinking beer can help improve bone density and improve cardiovascular health. These findings really surprised me because I've never heard of them on any TV show or in any health articles. So if it is actually good for you, why is the public ignoring this? As of now I'm considering focusing my paper on why people choose not to accept the fact that drinking beer(in moderation of course) is good for you.
