有些病人被告知，患乳腺癌不要喝豆漿，吃大豆，因為富含雌激素，實驗卻證明植物雌激素恰恰是幫助抑製阻斷人體雌激素，5年臨床實驗大豆製品有益於乳腺癌患者，降低複發率。我覺得什麽都適可而止就沒問題。

Among the most convincing epidemiological studies on the benefit, not harm, of soy is a study of 5,042 breast cancer survivors by researchers from Vanderbilt University.
Over a four-year period, the researches documented and correlated the amount of soy these women consumed with recurrence of and death from breast cancer. If there were any potential for soy to be truly harmful, it would appear in this population of women.
Instead, what was found was that women with the highest level of soy intake had a reduction in their risk of cancer recurrence by 32 percent, while their risk of mortality was reduced by 29 percent. This beneficial association with soy was seen regardless of whether the women had estrogen-receptor-positive or negative breast cancer.
In conclusion, my medical advice to you, whether you’re a woman or a man, is to fuel up on soy! It’s another healthful plant-based food.
