The research, published today in PLOS ONE by scientists from Oregon State University, found that a diet with reduced fat and cholesterol helped, but did not fully resolve liver damage that had already been done – damage that in turn can lead to more serious health problems, such as cirrhosis or even cancer. This study, done with laboratory animals, showed that diets low in fat and cholesterol could in fact aid with weight loss, improved metab- olism and health. But even then, if the diet was still high in sugar there was much less liver recovery, the scientists concluded. The findings are significant, sci- entists say, because liver problems such as nonalcoholic fatty liver dis- ease are surging in the U.S., affect- ing 10-35 percent of adults and an increasing number of children. The incidence of this problem can reach more than 60 percent in obese and type-2 diabetic populations. “Many people eating a com- mon American diet are develop- ing extensive hepatic fibrosis, or scarring of their liver, which can reduce its capacity to function, and sometimes lead to cancer,” said Donald Jump, a professor in the OSU College of Public Health and Human Sciences, principal investigator with the Linus Pauling Institute, and corresponding author on this research. “There’s a lot of interest in find- ing ways to help the liver recover from this damage, but this research suggests that diets lower in fat and cholesterol, even if they help you lose weight, are not enough,” Jump said. “For more significant liver recovery, the intake of sugar has to come down, probably along with other improvements in diet and exercise.” The issues are both serious and complex, the researchers said. “Everyone recognizes this is a serious problem,” said Kelli Lytle, an OSU doctoral candidate and lead author on this study. “We’re trying to find out if some of the types of dietary manipulation that people use, such as weight loss based on a low fat diet, will help address it. However, a common concern is that many ‘low-fat’ food products have higher levels of sugar to help make them taste better.” Weight loss does appear to help address some of the problems asso- ciated with the Western diet, the research shows. But according to this study, a diet with continued high levels of sugar will signifi- cantly slow recovery of liver dam- age that has already been done. Complications related to liver inflammation, scarring and dam- age are projected to be the leading cause of liver transplants by 2020, the researchers noted in their study. Such scarring was once thought to be irreversible, but more recent research has shown it can be at least partially reversed with opti- mal diet and when the stimulus for liver injury is removed. In this report, scientists studied two groups of laboratory mice that had been fed a “Western diet” and then switched to different, health- ier diets, low in fat and cholesterol. Both of the improved diets caused health improvements and weight loss. But one group that was fed a diet still fairly high in sugar – an amount of sugar comparable to the Western diet – had significantly higher levels of inflammation, oxi- dative stress and liver fibrosis. More research is still needed to determine whether a comprehen- sive program of diet, weight main- tenance, exercise and targeted drug therapies can fully resolve liver fibrosis, the study concluded. There have been confirmed influenza A cases at Sisters High School, according to nurse Trish Roy. Influenza (also known as the flu) is a conta- gious respiratory illness caused by flu viruses. It can cause mild to severe illness. The flu is different from a cold. The flu usually comes on suddenly. People who have the flu often feel some or all of these symptoms: • Fever or feeling feverish/chills (not every- one with flu will have a fever); • Cough; • Sore throat; • Runny or stuffy nose; • Muscle or body aches; • Headaches; • Fatigue (tiredness); • Some people may have vomiting and diar- rhea, though this is more common in children than adults. Others in the broader Sisters community have been struck down with flu. It can be quite debilitating and require significant rest and recovery. If you experience these symptoms, you are advised stay home from work or school and contact your health care provider. You may be eligible for treatment with an anti-viral medi- cation which is most effective if taken within 48 hours of symptom onset. For more information about influenza visit www.cdc.gov.
