近日,来自奥克兰大学的研究人员通过研究发现,极低热量饮食及益生菌的摄入或可帮助有效抑制糖尿病的发生。
领导这项研究的研究者Rinki Murphy获得了新西兰健康研究委员会资助的14.9万美金用于进行益生菌对前期糖尿病的研究;他表示,有效抑制前驱糖尿病进展成为2型糖尿病非常关键,而在现实生活中我们很难通过生活方式的干预措施来进行抑制。特定的益生菌菌种抑制2型糖尿病的效应可以帮助有效降低妊娠糖尿病的发生,并且可以改善患者的胰岛素敏感性及机体体重情况。
这项研究中,研究人员将会检测特殊的鼠李糖乳杆菌(Lactobacillus rhamnosus)以降血糖的方式,在不同剂量下抑制前驱糖尿病的效果,同时通过MRI扫描的方法来评估研究对象机体脂肪的分布情况;研究者想通过研究来确定是否抑制2型糖尿病的间歇性禁食方法可以通过益生菌的补充来使得有益效应被放大。
Murphy说道,每年大约10%的前驱糖尿病患者都会发展成为2型糖尿病患者,同时患者患心血管疾病以及死亡的风险较高。据估计截止到2021年新西兰将会有50万人患2型糖尿病,而届时这些患者每年进行治疗将会花费10亿美元。生活方式可以帮助抵御前驱糖尿病,但很多人难以坚持下来;而服用特定药物,比如二甲双胍、阿卡波糖等可以有效治疗糖尿病,但这些药物却存在一定副作用,而且并不适合于长期服用。
因此利用益生菌来抑制糖尿病的发生或许是一种安全有效的方法,目前大量证据表明肠道微生物菌群可以通过影响机体对来自饮食、饥饿、炎症及葡萄糖代谢的能量提取,从而在2型糖尿病的发生过程中扮演重要角色;益生菌可以帮助改善肠道菌群,同时使得肠道菌群变得更加健康;一旦研究人员通过研究确定是否鼠李糖乳杆菌的补充剂可以有效改善前驱糖尿病以及最佳的使用剂量,研究者将会进行大量研究来证实。
近来一项对超重人群的研究就发现,短期严格的热量限制或可明显改变肠道菌群的组成;最后研究者Murphy说道,目前间歇性禁食及益生菌疗法越来越流行,但我们需要进行随机的临床试验来证实其作用效果,后期我们将会进行大量研究来阐明间歇性禁食和益生菌对抑制糖尿病发生的潜在作用和机制。

Fasting and probiotics may help prevent diabetes
Very low calorie diets and probiotics may both help prevent Type2 diabetes and a scientific trial to investigate this will be underway in Auckland this year.
University of Auckland diabetes researcher, Dr Rinki Murphy has received a Health Research Council NZ grant for $149,000 to study probiotics for pre-diabetes.
Preventing the progression from prediabetes to Type2 diabetes is a health priority for New Zealand, and lifestyle interventions have been difficult to implement in real world settings," says Dr Murphy from the University's Faculty of Medical and Health Sciences.
"The effects of certain strains of probiotics in the prevention of Type2 diabetes are strongly encouraging with reduction in gestational diabetes, improvements in insulin sensitivity and weight loss seen with Lactobacillus supplements," she says.
"In this study we will test the effectiveness of a specific strain of Lactobacillus rhamnosus (HN001) given at different doses to patients with pre-diabetes, in terms of lowering blood glucose, and the distribution of body fat (specifically within the liver and pancreas) assessed by MRI scans."
"We are specifically recruiting patients of different ethnicities in Auckland who have pre-diabetes for this study to see how well this probiotic treatment may work," says Dr Murphy.
"We want to find out whether the intermittent fasting approach to prevent Type2 diabetes is amplified by probiotic supplementation."
Dr Murphy says about 10 percent of people with pre-diabetes develop Type2 diabetes each year and are at increased risk for cardiovascular disease and death even before the development of diabetes......
