Research has shown that there is little blood absorption of Stevia in rats and humans.
研究表明，水雷和人體的血液都很難吸收甜菊糖甙
Both organisms metabolize the chemical in the same way.
人體和小鼠的生理機制是以同種方式對化學物質進行代謝的
The joint FAO, WHO expert committee on food additives concluded
世界衛生組織添加劑食品專家委員會
that Reb A the main sweetening agent from Stevia has no evidence of an ability to damage or mutate DNA.
認為并無證據表明從甜菊糖甙中提取出的主要甜味劑瑞鮑迪甙A會損害或改變DNA
Which is usually how cancer begins.
而DNA的改變也正是癌癥產生的原因
This claim is based on research conducted in subcultures and living organisms.
這一論斷是在傳代培養和生命機體實驗的基礎上完成的
Research on mice and rats have shown
針對小鼠進行的研究表明
no DNA strain breakage or chromosome damage at doses up to 2000 milligrams per kilogram body weight per day.
每天每公斤體重攝入量為2000毫克并不會對DNA和染色體造成損害
For a 150 pound person this would be equivalent to a 136 grams
而對于一個150磅重的人來說
which if you think about it in terms of weight is equivalent to two fifths of a box of cheerios.
這意味著136克在重量上來說等于2/5盒櫻桃
In research focused on looking at the relationship between Reb A and cancer,
在針對瑞鮑迪甙A和癌癥之間關系的研究中，
most of the research on any Stevia compound has been done at the level of the cell and DNA damage.
大部分關于甜菊糖甙化合物的研究內容都對細胞和DNA有損害
Typically cancer is started by damage or mutations to DNA.
通常情況下，癌癥是由DNA損害或變異造成的，
The first study review looked at 8 groups of hamster cells
第一項研究報告觀察了8組倉鼠細胞，
exposed to Reb A for 4 and 24 hours of varying concentrations.
它們分別以不同強度接觸瑞鮑迪甙A從4-24小時不等
None of the groups showed significant reduction of DNA allegiance or breakage.
所有研究組都沒有顯示出嚴重的DNA粘連或斷裂
Researchers concluded that Reb A is non mutagenic
由此研究專家認為，瑞鮑迪甙A不會造成突變，
or does not cause damage to DNA and does not increase the risk of cancer.
或不會對DNA造成傷害也不會增加患癌幾率，
The second study injected mice with Reb A.
第二項研究向鼠體內注射了瑞鮑迪甙A
there were four different levels of Reb A doses exposed at two different lengths of time.
注射量分為四個等級，持續時間的長短也分為兩組
Blood samples were taken as the mice were observed.
在觀察過程中提取了小鼠的血樣
There was no significant increase in altered immature
在所有研究小組的樣本中
blood cells in the high dose group or any other treatment group.
未成熟的血細胞都未顯示出明顯的
The types of alterations to the blood cells included polychromatic
改變，血細胞發生的改變包括多色或者顏色的改變，
or changing colour and micronucleated or small nucleus.
小核以及小細胞分子的變化
Both poli chromatic and micro nucleiatic conditions are considered evidence of DNA damage and the increased risk of cancer.
多色改變和小核狀況的改變都被看做是DNA損傷和癌癥風險增加的證據，
Therefore researchers conclude that Reb A did not appear to increase the risk of cancer.
因此研究人員認為瑞鮑迪甙A似乎并不會增加患癌的風險
