Second-hand smoking results in liver diseaseA team of researchers at the University of California, Riverside has observed that even second-hand tobacco smoke exposure can result in nonalcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury in which fat accumulates in the liver of people who drink little or no alcohol.
The scientists found fat accumulated in liver cells of mice exposed to second-hand cigarette smoke for a year in the lab. Such........Go to the GI news blog (Added on 9/11/2009 7:43:42 AM)

Regular aerobic exercise reduces health concernsScientists from the University of Sydney, Australia determined that patients with a sedentary lifestyle who engage in routine physical activities lower their risk of nonalcoholic fatty liver disease (NAFLD). The lower risk of problems linked to fatty liver was not contingent upon weight loss, but a direct result from the increased aerobic exercise.
