Frequency of Consumption of Whole Fruit,Not Fruit Juice,Is Associated with Reduced Prevalence of Obesity in Korean Adults

BackgroundFruit consumption is known to be beneficial to health. However, the health benefits of fruit juice are controversial due to its high sugar content.ObjectivesTo examine the associations of frequency of consumption of whole fruit and fruit juice with obesity and metabolic syndrome.DesignThis cross-sectional study used data from the 2012-2015 Korea National Health and Nutrition Examination Survey.ParticipantsA total of 10,460 adults (4,082 men and 6,378 women) aged 19 to 64 years were included in the study.Main outcome measuresFrequency of consumption of whole fruit and fruit juice was evaluated using a food frequency questionnaire, and dietary sugar intake was calculated using a 24-hour recall. Obesity and abdominal obesity were determined using body mass index and waist circumference, respectively. Metabolic syndrome was defined on the basis of the National Cholesterol Education Program Adult Treatment Panel III.Statistical analyses performedMultiple logistic regression analysis was performed to examine the associations between frequency of whole fruit or fruit juice consumption and obesity and metabolic syndrome abnormalities.ResultsThe percentage of participants who consumed whole fruit daily was 32.6%, whereas 52.3% consumed fruit juice rarely. The average intake of total sugars was 14.9% of total energy, which was within the recommend range (<20% of total energy) for Koreans. Consuming whole fruit ≥1 time/day was associated with reduced prevalence of obesity, abdominal obesity, and elevated blood pressure compared with consuming whole fruit ≤1 time/wk. However, frequency of fruit juice consumption showed no association with obesity, abdominal obesity, and metabolic syndrome.ConclusionsFrequency of whole fruit consumption was associated with reduced prevalence of obesity and metabolic syndrome abnormalities among Korean adults with average total sugar intake within the recommended range.     

Both HCV and HBV are Major Causes of Liver Cancer in Southeast Asians

The incidence of hepatocellular carcinoma (HCC) is higher in Asian Americans than in other ethnicities. While hepatitis B virus (HBV) is common, hepatitis C virus (HCV) is more prevalent in some subgroups. Our goal was to determine the etiology of liver disease associated with HCC in subgroups of Asian Americans. This was an analysis of 510 Asian HCC patients at a US medical center. Patients were identified using ICD9 diagnosis. Multivariate logistic regression was used to study predictors of HCV as the cause of HCC. Patients were Southeast Asian, Chinese, and Korean, with similar gender, age, and foreign-born status. Southeast Asians had a similar proportion of HBV- and HCV-related HCC, while Chinese and Korean patients had a higher proportion of HBV-related HCC. HCC was usually associated with HBV in Chinese and Korean patients, but both HCV and HBV were important associations in Southeast Asians.
