Participants, 45-84 y at baseline (2000-2002), were followed through 2010. Diet was assessed by FFQ.

Antiapoptotic and Antioxidant Effects of Grape Seed Proanthocyanidin Extract (GSPE) in Preventing Cyclosporine A-induced Nephropathy - Nephrology (Carlton). 2012 Jan 18 - "The study demonstrates the abilty of GSPE to attenuate cyclosporine nephrotoxicity in rats, via its anti-oxidant and anti-apoptotic properties. GSPE is a natural product containing high amounts of polyphenols with known anti-inflammatory properties ... We demonstrated that GSPE prevents CsA nephropathy and that this effect is achieved by antiapoptotic and antioxidant activity. We also achieved a significant recovery in kidney functions without affecting CsA plasma levels" - See grape seed extract at Amazon.com.
Effects of Swimming Training on Blood Pressure and Vascular Function in Adults >50 Years of Age - Am J Cardiol. 2012 Jan 11 - "Forty-three otherwise healthy adults >50 years old (60 +/- 2) with prehypertension or stage 1 hypertension and not on any medication were randomly assigned to 12 weeks of swimming exercise or attention time control ... Casual systolic BP decreased significantly from 131 +/- 3 to 122 +/- 4 mm Hg in the swimming training group. Significant decreases in systolic BP were also observed in ambulatory (daytime) and central (carotid) BP measurements. Swimming exercise produced a 21% increase in carotid artery compliance (p <0.05). Flow-mediated dilation and cardiovagal baroreflex sensitivity improved after the swim training program"
Associations between frequency of tea consumption and health and mortality: evidence from old Chinese - Br J Nutr. 2012 Jan 16:1-12 - "The present study examines how self-reported frequency of tea consumption in daily life is associated with health and mortality among very old adults in China ... A total of four measurements between 1998 and 2005 resulted in 51 668 observations. Hazard regressions showed that men who drink tea almost every day have a 10-20 % lower risk of death compared to their counterparts who seldom drink tea, after adjusting for numerous confounders including baseline health. This relationship was stronger in younger male elders aged 65 to 84 years than in the oldest-old men aged 85 years and older. However, frequency of tea consumption was not significantly associated with mortality in women. Our analyses further show that high frequency of tea consumption is significantly associated with reduced OR of disability in activities of daily living, cognitive impairment, self-rated poor health, cumulative health deficits and CVD in both young elders and the oldest-old, and in both men and women" - See green tea extract at Amazon.com.
