How much Stevia is safe?"

Am doing some dense reading on RDI of stevia as per the Europeans who don't allow it in foods. they have now -from 1999 (not at all) to 2010 -- changed to allow to a limited amount by your body weight in kilograms.
This would be just pure dry weight, as stevia products always have other additives like maltodextrose or erythritol-ie Truvia ( MANY brand of "stevia have only 5%, with 95% as maltodexrose ) SweetLeaf seems to be the only liquid Stevia without added maltodextrose.
they can SAY "Stevia"to the public, (who assume "natural" but are using one of the many sweetness compounds of the plant,which respond differently during testing.
European Food Safety reasoning is that the sweetness component breaks down from the safe stevia glycosides to "steviol" in the gut which HAS been shown to become mutagenic (cancer causing) in the microflora of humans and mice during digestion..
What I can't find are any Japanese studies on cancer in use after 30-60 years. They import it by the ton, and so should be showing cancers by now. Anyone know?
==============EFSA evaluates the safety of sterol glycosides
http://www.efsa.europa.eu/en/press/news/ans100414
"Studies in humans demonstrated that daily doses of the steviol glycosides up to 1000 mg/person/day, equivalent to 16.6 mg/kg bw/day for a 60 kg person* (132 pounds) (corresponding to approximately 330 mg steviol equivalents/person/day or to 5.5 mg steviol equivalents/kg bw/day) were well-tolerated by individuals with normal glucose metabolism or type-2 diabetes mellitus.
*[Note: For a ~200 lb person then ~28.5 grams, or 1 ounce would be the daily limit. Using the packets of Truvia are 3.5 grams each, but they are MOSTLY erythritol (see below) ]
The Panel establishes an ADI for steviol glycosides, expressed as steviol equivalents, of 4 mg/kg bw/day based on application of a 100-fold uncertainty factor to the NOAEL for stevioside of 2.5% in the diet, equal to 967 mg stevioside/kg bw/day (approximately 388 mg steviol equivalents/kg bw/day), from a 2-year carcinogenicity study in the rat.
Conservative estimates of steviol glycosides exposure both in adults and in children suggest that it is likely that the ADI would be exceeded at the maximum proposed use levels.<<Meaning everyone might use TOO MUCH per day, due to love of sweet taste, thus risking cancers.

What is the acceptable daily intake (ADI) for Truvía® Natural Sweetener? [Link]
The ADI (Acceptable Daily Intake) is an estimate of the amount of a food additive that can be safely consumed every day over an entire lifetime without health risk. It typically is calculated from all the available toxicology safety studies. The highest dose in these studies that has been shown to cause no adverse health effects is the starting point. This dose is then divided by at least 100 to determine the ADI. So ADI value does not represent the line between safe and unsafe, but instead includes a very wide added safety factor. For Truvía® stevia leaf extract, the ADI is equivalent to about 12 mg/kg body weight/ day. Even this value is well above the estimated daily consumption based on clinical studies. In those studies, the average estimated daily intake was 1.3 mg/kg bw/day for adults, 1.4 mg/kg bw/day for diabetics, and 2.1 mg/kg bw/day for children. Even heavy users of Truvía® stevia leaf extract products are unlikely to consume an amount near the ADI which would only be reached with 29 sachets or sweetness equivalent to 58 teaspoons of sugar every day for their entire life. <<<Because Truvia is 70% as sweet as sugar people use more of it to get the taste they are used too… So one could easily use 12-20+ packets in just 2 cups of coffee, plus in baking, making LC desserts, adding to protein shakes, tea, cocoa etc.

Interesting. I've also personally found Sweetleaf to the only one that doesn't trigger negative reactions in me.0
