3 reasons why you have a non-alcoholic fatty liver and butter is not one of them!
A new study, published in the Journal of Hepatology, does not inspire one expert to mince words. “Our chairs are slowly but surely killing us,” says Michael I. Trenell, PhD, Professor of Metabolism & Lifestyle Medicine at Newcastle University, UK.
No, it’s not a new science fiction movie about comfortable chairs that lull us into complacency and then murder us in our sleep. Rather, he’s referring to the findings of a new study conducted in Korea. It’s nothing particularly novel. You’ve undoubtedly heard it all before: Sitting is bad for your health.
Seungho Ryu, PhD, MD, explained: "We found that prolonged sitting time and decreased physical activity level were positively associated with the prevalence of [non-alcoholic fatty liver disease] (NAFLD) in a large sample of middle-aged Koreans." Co-author Yoosoo Chang, MD, PhD, added: "Our findings suggest that both increasing participation in physical activity and reducing sitting time may be independently important in reducing the risk of NAFLD, and underlines the importance of reducing time spent sitting in addition to promoting physical activity."
NAFLD is an increasingly common disease that was once rare. It is so-named because it results in damage that resembles the damage to the liver more commonly seen among people who have endured a lifetime of alcoholism and liver disease.
"The data from Ryu and colleagues add to the strong and alarming evidence that sitting too much and moving too little has significant negative consequences for cardio-metabolic health," commented Michael I. Trenell, PhD. "The message is clear, our chairs are slowly but surely killing us. Our body is designed to move and it is not surprising that sedentary behavior, characterized by low muscle activity, has a direct impact on physiology. With a dearth of approved drug therapies for NAFLD, lifestyle changes remain the cornerstone of clinical care. The challenge for us now is to 'stand up' and move for NAFLD, both physically and metaphorically," Professor Trenell added.
