根據現有的數據和相關的不確定性，在營養充足的情況下，添加糖和遊離糖的攝入量應盡可能低。減少添加糖和遊離糖的攝入會以相似的程度減少總糖的攝入。部分原文報道如下：

 

　　Following a request from five European Nordic countries, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was tasked to provide scientific advice on a tolerable upper intake level (UL) or a safe level of intake for dietary (total/added/free) sugars ba sed on available data on chro nic me tabolic diseases, pregnancy-related endpoints and dental caries. Specific sugar types (fructose) and sources of sugars were also addressed. The intake of dietary sugars is a well-established hazard in relation to dental caries in humans. ba sed on a systematic review of the literature, prospective cohort studies do not support a positive relatio nship between the intake of dietary sugars, in isocaloric exchange with other macronutrients, and any of the chro nic me tabolic diseases or pregnancy-related endpoints assessed. ba sed on randomised co ntrol trials on surrogate disease endpoints, there is evidence for a positive and causal relatio nship between the intake of added/free sugars and risk of some chro nic me tabolic diseases: The level of certainty is moderate for obesity and dyslipidaemia (> 50–75% probability), low for non-alcoholic fatty liver disease and type 2 diabetes (> 15–50% probability) and very low for hypertension (0–15% probability). Health effects of added vs. free sugars could not be compared. A level of sugars intake at which the risk of dental caries/chro nic me tabolic diseases is not increased could not be identified over the range of observed intakes, and thus, a UL or a safe level of intake could not be set. ba sed on available data and related uncertainties, the intake of added and free sugars should be as low as possible in the co ntext of a nutritio nally adequate diet. Decreasing the intake of added and free sugars would decrease the intake of total sugars to a similar extent. This opinion can assist EU Member States in setting natio nal goals/recommendations.
