We are talking more than ONE diet soda a day So if you are having Aspartame in more than one thing, then you should stop.
(Quote form article) “The health statistics for nearly 48,000 men and over 77,000 women over the age of 20 were reviewed for the featured study. They found that men who consumed more than one diet soda per day had an increased risk of developing multiple myeloma and non-Hodgkin’s lymphoma. Interestingly enough, this association was not found in women.
Leukemia was associated with diet soda intake in both sexes.
One hypothesis for the difference between the sexes is that men have a higher activity of the enzyme ADH, as I mentioned earlier, which metabolizes methanol and converts it to formaldehyde. More formaldehyde circulating in your blood would naturally have more opportunity to cause greater damage.”
(Humans are the only animals who do not have the protective mechanism to compensate for methanol toxicity. So evaluating methanol toxicity in animals is a flawed model for testing human toxicity. Even so, there are lots of papers proving that Aspartame is toxic to animals, the only other study which was done on humans, which did not show any harm, was only four and half months long).
