據《自然（Nature）》一篇研究發現，人工甜味劑會影響老鼠腸道菌叢，進而出現葡萄糖耐受不良，研究還收集了約400位自願者，發現代糖重度使用者的HbA1c（血糖長期測量指標）會稍微增高，有幾位甚至在大約1星期血糖就飆高到糖尿病初期的症狀。此外人工甜味劑還有助於腸道中幫助攝取食物的能量轉化為脂肪的菌叢生長，因此造成脂肪堆積。
人工甜味劑會影響糖的代謝，增加罹患糖尿病風險，也會造成脂肪堆積，其實並不如大眾認為的那麼健康，甚至比含糖飲料更可怕，炎炎夏日將近，該如何消暑解渴？看來以白開水代替飲料才是萬全之策。
小編評：小編查了網路資料，發現這篇新聞提到的是2016年的研究（如下）。
Fourteen observational studies evaluating the association between NNS consumption and the development of metabolic diseases and twenty-eight clinical trials studying the effects of NNS on metabolism were included. Finally, two meta-analyses evaluating the association between the consumption of NNS-containing beverages and the development of type 2 diabetes were identified.
Some observational studies suggest an association between NNS consumption and development of metabolic diseases; however, adiposity is a confounder frequently found in observational studies. The effects of the NNS on glucose metabolism are not clear. The results of the identified clinical trials are contradictory and are not comparable because of the major existing differences between them. Studies evaluating specific NNS, with an adequate sample size, including a homogeneous study group, identifying significant comorbidities, with an appropriate control group, with an appropriate exposure time, and considering adjustment for confounder variables such as adiposity are needed.
有長期在生酮飲食的就知道
好像只有赤藻糖醇不會造成腎上腺素跟升糖素血糖上升而破酮
其他的代糖其實沒有甚麼用
吃代糖根本促進飢餓
