8 recent reports on diet’s protective, risk-increasing effects on liver health
March 23, 2018

Diet and lifestyle play a large role in liver health. Lately, researchers have made several important discoveries regarding the ties between diet and the gut microbiome, and identified specific dietary components that either have protective qualities for liver health or increase the risk for liver disease and cancer.

The following reports include details on diet’s effect on the gut microbiome, the increased risk for fatty liver disease among individuals with a high intake of red and processed meat, the protective effects of early childhood vitamin E intake and moderate coffee intake for adults, and a recent CDC report on adult binge drinking.

High red, processed meat intake increases fatty liver disease, insulin resistance risk

High consumption of red meat and processed meat correlated with an increased risk for nonalcoholic fatty liver disease and insulin resistance, according to recently published data.

“World meat consumption has increased in the last decades, while evidence of its harmful effect is mounting, particularly of red and processed meat consumption,” Shira Zelber-Sagi, PhD, from the Tel Aviv Medical Center, and colleagues wrote. According to the researchers, their results indicate a potential protective role of a vegetarian or low animal protein diet, including the Mediterranean diet, which has previously shown benefit in the gut microbiome.

CDC: Adult binge drinkers collectively consume 17.5 billion drinks a year

U.S. adults consumed approximately 470 binge drinks per drinker in 2015 for a total of 17.5 billion binge drinks, according to findings recently published in the American Journal of Preventive Medicine.

Binge drinking occurs when a man has five or more drinks per 2-hour occasion, and when a woman has four or more drinks per 2-hour occasion, according to the researchers. Read more

Diet, lifestyle outweigh genetic impact on gut microbiome

Genetics play a surprisingly minor role in shaping the gut microbiome, while environmental factors like diet and lifestyle appear to have the greatest impact, according to new research published in Nature.

These findings provide strong new evidence supporting the concept of modifying the gut microbiota to improve human health, investigators from the Weizmann Institute of Science in Israel concluded. Read more

Early childhood vitamin E intake linked to lower risk for elevated ALT

Higher early childhood intake of vitamin E correlated with a lower risk for elevated mid-childhood alanine aminotransferase levels, according to recently published data.

“We are still learning more about the long-term risks of high ALT in childhood. Cross-sectional studies of children show a link between ALT and metabolic risk, and adults longitudinal studies show that higher ALT levels are associated with later risk of diabetes and mortality,” Jennifer A. Woo Baidal, MD, MPH, from the Columbia University Medical Center, New York, told Healio Gastroenterology and Liver Disease. “Diet quality – not just calories – matter, and most Americans don’t get enough alpha-tocopherol in their diet. Promoting a diet rich in antioxidants such as alpha-tocopherol should start early in life and may help promote later liver health.”

最近的8篇关于饮食对肝脏健康的保护性风险增加影响的报道
2018年3月23日

饮食和生活方式在肝脏健康中起着重要作用。最近，研究人员在饮食和肠道微生物群之间的关系方面取得了一些重要发现，并确定了具有保护肝脏健康品质或增加肝病和癌症风险的特定饮食成分。

以下报道包括饮食对肠道微生物群的影响，红肉和加工肉类摄入量高的个体患脂肪性肝病的风险增加，儿童早期维生素E摄入量的保护作用和成年人中等咖啡摄入量以及最近的CDC关于成人暴饮的报道。

高红，加工肉类摄入量会增加脂肪肝疾病，胰岛素抵抗风险

根据最近公布的数据显示，红肉和加工肉类的高消费量与非酒精性脂肪肝疾病和胰岛素抵抗风险增加相关。

“特拉维夫医疗中心的Shira Zelber-Sagi博士及其同事写道：”世界肉类消费量在过去几十年中有所增加，而其有害影响的证据正在上升，尤其是红色和加工肉类消费。“研究人员表示，他们的研究结果表明，素食或低动物蛋白饮食（包括地中海饮食）的潜在保护作用，以前在肠道微生物群中表现出益处。阅读更多

疾病预防控制中心：成人暴饮暴食者每年共消耗175亿个饮料

根据最近在美国预防医学杂志上发表的研究结果，美国成年人在2015年每个饮酒者消耗大约470份狂饮饮料，总共有175亿狂欢饮料。

根据研究人员的数据，当一个男人每2小时饮酒5杯或更多时，以及每2小时饮酒4次或4杯以上时，就会发生狂饮。阅读更多

饮食，生活方式超过对肠道微生物群的遗传影响

根据发表在Nature上的新研究，遗传学在塑造肠道微生物群体方面发挥的作用微乎其微，而饮食和生活方式等环境因素似乎影响最大。

这些研究结果提供了强有力的新证据，支持修改肠道菌群以改善人类健康的观念，以色列魏兹曼科学研究所的研究人员总结说。阅读更多

儿童早期维生素E摄入量与ALT升高的风险降低有关

根据最近公布的数据，较高的儿童期维生素E摄入量与儿童谷丙转氨酶水平升高的风险降低相关。

“我们仍然在学习更多关于儿童时期高ALT的长期风险。儿童的横断面研究显示ALT与代谢风险之间存在联系，成年人纵向研究显示ALT水平升高与糖尿病的晚期风险和死亡率相关，“哥伦比亚大学医学院Jennifer A. Woo Baidal博士，MPH纽约中心告诉Healio胃肠病学和肝病。 “饮食质量 - 不仅仅是卡路里 - 重要，大多数美国人在饮食中得不到足够的α-生育酚。促进富含抗氧化剂如α-生育酚的饮食应该在生命的早期开始，并可能有助于促进晚期肝脏健康。
