According to a study published this week in The British Journal of Nutrition, the consumption of a three ounce portion of watercress reduced the presence of a key tumor growth factor six and eight hours after eating the watercress in healthy patients who had previously been treated for breast cancer.
The study was conducted by the Cancer Research Centre at the School of Medicine, Southampton General Hospital in the United Kingdom.
The study concluded watercress is as therapeutic as traditional drug treatments with tamoxifen and herceptin, commonly used chemotherapy drugs. The study also said that through regular consumption, watercress "has the potential to confer valuable protection against cancer in general."
"Watercress has the ability to turn off HIF1, a signal sent out by cells calling for blood supply," said noted aging scientist Dr. Nicholas Perricone.
When HIF1 becomes incorrectly regulated, otherwise harmless precancerous clusters of cells have the opportunity to grow to form invasive tumors. "Scientists have been looking for anti-angiogenesis agents for years because if we can turn off the blood supply, we can kill the cancer," said Perricone. "And it looks like watercress can do that ."
Another study published in The American Journal of Clinical Nutrition in February of 2007 showed that, in addition to reducing DNA damage, a daily dose of watercress increased the ability of cells to further resist DNA damage that may be caused by free radicals.
In the study, 60 men and women, half of whom were smokers, consumed their usual diet plus 85 grams of raw watercress daily for eight weeks. Blood samples were analyzed for plasma antioxidant status and DNA damage in lymphocytes, a type of white blood cell. Watercress consumption significantly reduced lymphocyte DNA damage.
In the time of the Romans, Greeks and Persians watercress was used as a natural medicine, prescribed for migraines, anemia, eczema, kidney and liver disorder and tuberculosis.
英国科学家说，西洋菜是新的超级食品，可以防止某些类型的癌症。
根据发表在英国营养杂志，一个西洋菜三盎司的部分消费减少，本周六的研究和八个小时后患者的健康饮食在西洋菜谁以前对乳腺癌治疗的肿瘤生长的一个关键因素的存在癌症。
这项研究是由癌症研究中心医学系，南安普敦综合医院的英国。
研究的结论豆瓣一样赫赛汀与传统的药物他莫昔芬和常用化疗药物治疗，治疗。该研究还表示，通过经常食用，西洋菜“有可能对癌症授予一般宝贵的保护。”
“西洋菜有能力关闭HIF1，一个信号发出去的血液供应的单元格，说：”科学家指出，老龄化尼古拉斯裴礼康医生。
当HIF1变得不正确调控，否则无害的癌前细胞群有机会成长，形成浸润性肿瘤。“科学家们多年来一直在寻找抗血管生成剂，因为如果我们可以关闭的血液供应，我们可以杀死癌细胞，说：”裴礼康。“它看起来像西洋菜可以做到这一点。”
在美国临床营养学杂志上发表于2007年2月的另一项研究表明，除了减少DNA损伤，每日剂量的西洋菜增加了细胞的能力，以进一步抵御DNA损伤可能是由自由基造成的。
在这项研究中，60个男性和女性，其中一半是烟民，他们平时的饮食消费原料豆瓣加85八星期每天克。血液样本进行了分析血浆抗氧化和DNA损伤的细胞，一种白血细胞类型。沃特克雷斯消耗显着降低淋巴细胞DNA损伤。
在罗马人，希腊人和波斯人西洋菜时间被用来作为天然药物用于治疗偏头痛，贫血，湿疹，肾脏和肝脏疾病和结核病的规定。
