One study in the food and chemical toxicology journal analyzed
這本化學和藥理雜志組織的一項研究分析了
the carcinogenic or DNA damaging effects of sucralose in mice.
蔗糖素的致癌性和對DNA造成的損傷，
This study lasted a 104 weeks,
該實驗持續了104周
and was made up of three treatment groups and one control group.
包括3個實驗組和1個參照組
The study evaluated for the formation of tumours.
這項研究的目的是測評腫瘤的形成，
To observe tumour formation the researchers handled
要觀察腫瘤的形成，研究人員每周對小鼠進行一次檢查
and palpitated the miceonce a week to look at for any abnormal growths.
以便及時發現任何異常的生長情況
At the end of the 104 weeks an autopsy was performed on each of the surviving mice.
104周結束后，每只存活下來的小鼠都接受了解剖檢查
The researchers grouped organs and body parts into 29 categories to search for tumours.
研究人員將器官和身體組織分成29個部分進行腫瘤篩查
At a 104 weeks
在這104周中，
the researchers determined the approximate average intakes of sucralose for each treatment group as listed on the sign.
研究人員將每個實驗小組的平均蔗糖攝入量都計算出來并且進行標注
Also researchers complied the data from 29 organs or body regions
同時，研究人員還編撰了29個器官和身體組織的研究數據，
to compare the treatment groups to the control group.
對兩組進行比較
The sucralose treatment did not significantly increase the number of tumours
在此次的蔗糖實驗中，實驗組與參照組相比，
or influence the types of tumours when compared to the data of the control group.
腫瘤的患病率或腫瘤的種類并沒有增加
This study concluded that the results did not suggest
研究結果表明
any carcinogenic or DNA damaging effects from the sucralose.
蔗糖并不會產生任何致癌效果或者對DNA造成損害作用
Next we will review the consumption recommendations for sugars and sweeteners presented.
下面我們來看糖和甜味劑的每天建議攝入量，
The dietary guidelines for Americans and the World health organization
美國飲食指南和聯合國衛生組織的飲食指南對于
have very different recommendations for added sugars.
添加糖的建議攝入量有很大不同
The dietary guidelines recommend less than 25% of a person's calories come from added sugar.
根據飲食指南，每人每天的建議攝入量為飲食中來源于添加糖的能量應小于25%
Although added sugar should be limited because it provides little nutrients besides energy.
添加糖的攝入量應該控制在一定范圍內，因為除了能量外，它能提供的營養很少
The dietary guidelines focus on people receiving enough nutrients in terms of energy.
飲食指南關注的是人們攝入的能量值
The World Health Organization recommends less than 10% of a person's calories come from added sugar.
世界衛生組織規定，每人每日從添加糖中獲得的能量應小于10%
This is to prevent diet related chronic disease
以便預防與飲食有關的慢性病，
along with maintaining a good nutritional status.
同時保證良好的營養狀況
In terms of a 2000 calorie diet a person could consume up to 500 calories from added sugar if following the dietary guidelines.
根據美國標準，若一頓飯含有2000卡，那么最多有500卡可以來自添加糖
But according to the WHO 200 calories or less would be allowed.
但是根據世界衛生組織，來自于添加糖的最多只能有200卡
