Another branch of the WHO, the Joint WHO and Food and Agriculture Organization’s Expert Committee on Food Additives has assessed the risk and developed recommendations on how muchis safe to consume. They have recommended the acceptable daily intake to be 0-40mg per kg of body weight.
Commercial names for aspartame include Equal, Nutrasweet, Canderel and Sugar Twin. In Australia, the acceptable daily intake is 40mg per kg of body weight per day, which is about 60 sachets.WHAT EVIDENCE HAVE THEY USED TO COME TO THIS CONCLUSION? There were only three human studies that looked at cancer and aspartame intake. These large observational studies used the intake of soft drinks as an indicator of aspartame intake.
The third study, also from the US, found an increase in liver cancer risk in men who never smoked and drank two or more artificially sweetened drinks a day.
