Anyone who willing chooses to drink/eat any artificial sweetener/no added sugar/sugar free food and drink, really needs to become educated about the additives used.
Aspartame, if there is one to say no to its this.
Apart from the fact that it rots your brain and lowers your IQ (fluoride anyone), there are many other side effects.

As many have said already, it's not Americans fault they have so many obesity problems, and it is no accident either.
All their meat is pumped full of hormones that are designed to feminise the people who consume it, your pesticides do this as well by contaminating the ground water.
There is a good video on google called "Flow", worth watching if you are interested (explains this much better then I could ever hope to).
The pesticide is manufactured in Europe, but its use if banned here, yet it is used in America incessantly.
A dumbed down populous with a lack of testosterone is the best way to keep people easily manageable, otherwise there would have been a revolt in the US by now.
All this leads to the general public being more susceptible to advertisement and influence, and therefor fall victim to unscrupulous corporations such as McD etc not to mention big Pharma which is raping the US citizens.
Don't get me wrong though, I see the same happening here too. Its just that it has been happening in America long enough now to easily see the toll it has taken on the population.
