The WHO's Joint Experts Committee on Food Additives has approved, based on long-term studies, an acceptable daily intake of steviol glycoside of up to 4 mg/kg of body weight. In 2010, The European Food Safety Authority established an acceptable daily intake of 4 mg/kg/day of steviol, in the form of steviol glycosides. Meanwhile, the Memorial Sloan Kettering Cancer Center warns that "steviol at high dosages may have weak mutagenic activity," and a review "conducted for" the Center for Science in the Public Interest notes that there are no published carcinogenicity results for rebaudioside A (or stevioside).
