Hepatitis C virus infection strongly linked to developing diabetes

Jul 26, 2007


In this Chinese study 4,958 people at least 40 years of age without diabetes were followed for 7 years. Those with hepatitis C infection had a big jump in the risk of developing diabetes and the incidence of diabetes was 70% higher in these patients. Hepatitis B did not increase the risk. Compared to normal weight individuals without the infection, if a person was overweight and had hepatitis C there was a 300% higher risk of developing diabetes. The study is published in the July 15th, 2007 issue of the American Journal of Epidemiology.

Antioxidants decrease the risk of painful knee arthritis

Australian researchers followed 293 middle-aged people for ten-years; they were healthy and free of knee pain at the start of the study. At the end of ten-years their knee tissue was examined using MRI scans. In general, the higher a person?s dietary vitamin C at the start of the study, the lower the risk of developing bone changes that contribute to arthritis at the ten-year mark; the risk dropped by 50%. Having sufficient dietary Lutein and Zeaxanthin decreased the risk of developing defects in the cartilage by 29%. The study is published online ahead of print in the July 6th, 2007 issue of the journal Arthritis Research and Therapy.

Soy Isoflavones may cut the risk of prostate cancer by 60%

A new case-control study recruited 200 Japanese men with prostate cancer ranging from stage 1 (1 man) to stage 4 (24 men). Their dietary intake of soy was evaluated and compared to that of cancer-free men. Intake of the Soy Isoflavones Genistein and Daidzein was significantly associated with a decreased risk of prostate cancer. When comparing the highest average isoflavone intake of 90mg or greater to the lowest of 30.5mg or less, having 90mg or greater of Soy Isoflavones daily was associated with a 58% decreased risk of developing prostate cancer. The study is published in the August 2007 issue of the Journal of Nutrition.
