Interestingly, under the category of “Everyone should avoid” are sweeteners: Aspartame, Acesulfame-Potassium and Saccharin.
This is their reasoning:
A new Italian animal study found that long term use of aspartame (marketed as Equal and found in soft drinks ), in amounts similar to that found in the human diet and below the acceptable intake deemed safe by Health Canada and the States, could increase the risk of leukemia, lymphoma and breast cancer.
The CPSI points out that studies done on Acesulfame-Potassium (Acesulfame-K- found in diet soda and foods) in the 70s showed a link between the sweetener and cancer and the US FDA hasn’t required better research since.
They also point out that animal studies have shown that Saccharin (Sweet n’ Low) can cause cancer of the bladder, uterus, ovaries, skin and other organs. A US National Cancer Institute study found that people that ate large amounts of saccharin had higher rates of bladder cancer than people who used smaller amounts. The use of saccharine in foods and drinks is illegal in Canada but Sweet n' Low is sill around.
