I'm fairly anti-soda, but I do not believe the government should start dictating people's personal habits. I am all for the government doing education campaigns to inspire people make better decisions.
The trouble with that idea is that private industry via the government is suppressing information.
I recently saw the documentary "FedUp", which didn't have much new to say about the evils of sweeteners and refined flour, but it had a lot to say politically.
At one point the U.N. was about to publish a report stating that to safeguard their health in addition to controlling their weight, people should limit their sweetener & refined flour consumption to no more than 10% of their calories a day ( 50 grams of sweetener in your food per day on a 2000 calorie diet. A bottle of grape Fanta soda has 80 grams of sugar, a cup of orange juice has 20 grams ).
In the documentary, it was described how the American food industry used its influence to get the George W. Bush administration to convince the U.N. to not publish that report.
While the grams of sugar might be on food labels, the percentage of the limit is not printed on there--- by conscious choice, making it harder for people to know when they are going overboard.
