It's annoying when a consensus is overturned. We follow gov. advice and if it changes all we can do is change with it.
Or perhaps decide for ourselves maybe?
When the Gov decided in the 90s that nutritional advice would be science based I was all for it and quite excited that at last we would see some sound advice given to people. The excitement died for me very quickly when I realised that science is like history - you only know what you know now, and tomorrow some further research can tell a whole different story. Research into nutrition is especially dicey because you can't test on humans, so a lot of the data is extrapolated from what we learn about the sick.
Another problem is that having invested billions of pounds in training doctors and other medics, producing training programs, books, teaching aids, showing what today's science shows and how they should be advising the public it's very hard to change the flow and re-educate everyone.
People's reputations are also on the line - they don't want things to change that they have been backing for 20 years. Not to mention a whole raft of the science that is done on foods is done by pharmaceutical companies and food companies, who all want a piece of the pie.
I no longer have any interest in nutritional guidelines and just make my own mind up what to eat.
Sorry, that was a bit long.
