Aromatase activity is anything that encourages the conversion of androgens to estrogens. In estrogen-dependent cancers, for obvious reasons, one does not want androgens converted to estrogens. Wine can, apparently, prevent this from happening in ordinary circumstances. When the body鈥檚 hormones are artificially supplemented, however, wine may inhibit further androgens from being converted, but there is still going to be sufficient estrogen to aid cancer progression. Could this be why wine-drinking is not effective protection for women who use hormone replacement therapy? There is much to learn. But all indications are that red wine is inclined to be our ally against the most common form of cancer for Western women.
For men, of course, cancer most commonly turns up in the prostate鈥攂ut here too is good news. It comes from a 2004 study by researchers at Seattle鈥檚 Fred Hutchinson Cancer Research Center who found that men who drink red wine significantly decrease their risk of developing prostate cancer. In comparison, white wine, beer and other spirits had no effect. Janet L. Stanford, the researcher who led the study, commented that 鈥淎mong men who consumed four or more 4-ounce glasses of red wine per week, we saw about a 60 percent lower incidence of the more aggressive types of prostate cancer. The more clinically aggressive prostate cancer is where the strongest reduction in risk was observed.鈥?The polyphenol resveratrol was specifically given the credit for these benefits, though as other researchers have realized, there are many powerful flavonoids (a subgroup of polyphenols) in wine that contribute as much or more than resveratrol to protection from cancer. The common denominator among all these polyphenolic substances is that thei上一页 [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] 下一页 更多英语知识学习请访问:英语学习
