Green tea is a rich source of phytochemicals that have the potential to interact with – and regulate –xenobiotic metabolizing enzymes. Barbara Fuhrman, from the US National Cancer Institute (Maryland, USA), and colleagues followed nearly 200 pre- and post-menopausal women who were surveyed for their frequency of green tea consumption and assessed for markers of estrogen metabolism. The team found that daily consumption of green tea associated with lower levels of estrogen metabolites, suggested to be a causal factor in the development of breast cancer. Specifically, in postmenopausal women, urinary estrone and estradiol were approximately 20% and 40% lower, respectively, in women drinking green tea daily compared to those drinking less than once a week. The study authors conclude that: “Findings suggest that intake of green tea may modify estrogen metabolism or conjugation and in this way may influence breast cancer risk.”

Tip #136 - Live Healthy, Live Longer
A number of studies validate lifestyle and other modifiable factors to promote a long and healthy lifespan:
• Cambridge University (United Kingdom) researchers report that healthy lifestyle choices can extend lifespan by 14 years. In a study of 20,000 men and women, ages 45 to 79, conducted for 13 years, Kay-Tee Khaw and colleagues found that those study subjects with the lowest number of healthy behaviors were four-times more likely to die, most notably from cardiovascular disease. Specifically, the team found that study participants with the lowest healthy lifestyle scores had the same risk of dying as someone with the highest healthy lifestyle scores who was 14 years older. The lifestyle change with the biggest benefit was smoking cessation, associated with an 80% improvement in lifespan. The second most significant change was increased consumption of fresh fruits and vegetables. Thirdly, moderate drinking; and fourthly, staying physically active, rounded out the four most beneficial lifestyle choices to extend lifespan.
• US Centers for Disease Control and Prevention (Atlanta, Georgia USA) researchers studied data collected on 23,153 German men and women, ages 35 to 65 years, who participated in the European Prospective Investigation Into Cancer and Nutrition-Potsdam study. The team found that four lifestyle factors -- namely never smoking, having a body mass index (BMI) of 30 or less, exercising 3.5 hours a week and eating a healthy diet – slashed the risk of cardiovascular disease, diabetes, and cancer by a staggering 80%.
Lifestyle choices including not smoking, eating fresh foods, engaging in regular exercise, minimizing psychological stress, and drinking in moderation are basic tenets of the anti-aging lifestyle. By embracing these concepts, not only might we extend how long we may live, but how well. A prolonged healthspan -- the length of time that we are able to live productively and independently – is, in many ways, as important as an extended lifespan.
