I don't know that you can attribute bad eating habits to the recommendations of public health organisations. Perhaps the public is just not following those recommendations? My understanding is that processed foods and sugary drinks are consumed in great numbers, but that is certainly not in accordance with the recommendation of any public health organisations that I know of.
Also, as far as I know, public vaccination programmes have greatly reduced, and almost eliminated many diseases like measles, tetanus and typhoid, not just in the US but the world over, although of course measles is making a comeback.
Are you perhaps drawing a conclusion about public health bodies in western countries in general, from an experience with health services in the US? The US seems to be very peculiar in how it treats public health. I live in the UK and I wouldn't say that the national health service (the NHS) has collapsed. It has its problems and it's being attacked constantly but for the time being, it's working fine. The same is true for most central European countries.
