In and of itself sugar is far better! Aspartame is pure poison and not fit for human consumption. It is a neuro-toxin which is a drug not a food. There is plenty of great info on the web regarding the dangers of this stuff. It has killed and is killing many many more people than most realize. It is an epidemic.
The problem with sugar products is that they are way over consumed! They become addictive to many people. Just do some reading here if you need convincing of this. This long term over consumption of sugar and grain products is devastating to many people. They simply start to break down systemically.
I don't know what to tell you about your government guidelines. They are BS. I could not promote something I vehemently disagree with. How would you sleep at night doing that? Something to think about. I have been eating real, organic whole foods, no sugar products, limited grains for several years now long before I ever heard of paleo or primal. I'm here because it closely lines up with this. I can say without a doubt that it works wonders as far as health goes. I feel absolutely great almost all the time. Better than I've ever felt. THAT is the measuring stick. Not some test numbers. There are lots of people walking around with "good numbers" and they feel crappy most days. Not a fan of the medical industry. I do however wish you well with this!
