Serum Antioxidant Status and Metabolic Syndrome |
|
"Serum Antioxidant Status Is Associated with Metabolic Syndrome among U.S. Adults in Recent National Surveys," Beydoun MA, Shroff MR, et al, J Nutr, 2011 March 30; [Epub ahead of print]. (Address: National Institute on Aging, National Institute of Health, Intramural Research Program, Baltimore, MD 21224, USA). |

In a cross-sectional study involving data from adults between the ages of 20 and 85 years of age, those with the metabolic syndrome were found to have consistently lower serum carotenoid concentrations, as compared to those with the metabolic syndrome. Vitamin C levels were inversely associated with metabolic syndrome, HOMA-IR, and hyperuricemia. Retinol+retinyl esters were inversely associated with the metabolic syndrome in men, inversely associated with elevated CRP, and positively associated with hyperuricemia. The authors conclude, "Future intervention studies of dietary and lifestyle change must be conducted to assess the utility of modifying serum antioxidant concentrations, especially carotenoids, given their suboptimal levels among U.S. adults with MetS, for the prevention of type 2 diabetes and various cardiovascular endpoints." |
Ben's Comments - They found that the more Vitamin C, carotenoids and Vitamin A you had the less likely you are to develop Metabiolic Syndrome

Protecting Against Oxidative Stress May Increase Life Expectancy in Initially Healthy Population |
|
"Vitamin E may affect the life expectancy of men, depending on dietary vitamin C intake and smoking," Hemila H, Kaprio J, Age Ageing, 2011 March; 40(2): 215-20. (Address: Department of Public Health, University of Helsinki, POB 41, Helsinki FIN_00014, Finland). |

In a study involving 10,837 males between the ages of 50 and 69 years who smoked at least 5 cigarettes/day at baseline, and who were followed up with past the age of 65 years, vitamin E reduced as found to be associated with a 24% reduction in mortality when subjects were 71 years of age and older, while having no such effect on those 65-70 years of age. In subjects who smoked less than a pack of cigarettes/day, and whose vitamin C intakes were higher than the median, vitamin E extended the lifespan by 2 years at the upper limit of the follow-up age span. The authors conclude, "This is the first study to strongly indicate that protection against oxidative stress can increase the life expectancy of some initially healthy population groups. Nevertheless, the lack of effect in 80% of this male cohort shows that vitamin E is no panacea for extending life expectancy." |
