Soy food good for women
Women who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research.
The studies add to a growing body of evidence about the role of diet in cancer. Cancer e_perts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of e_ercise.
The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects.
A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week.
Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cycloo_ygenase-2 or CO_-2 enzyme. CO_-2 affects inflammation, which may play a role in tumour growth.
Hello!Everyone.
I am flying today, speech is the ideal wing, as a middle school student, we are in love fantasy, love to dream, love highlight their personality, love and zhang yang us different, we were not mistaken, we now are not qualitatively period of development, there is no one standard for us to judge their own life and values. we always let adults know that we can do it yourself to live, you can solve their own problems, but we have some dependence. love day dreaming, perhaps today we want to be a teacher, to educate our newcomers, and perhaps tomorrow we want to be a scientist to e_plore our humanity to the present do not know some of the mystery, or we have no way to e_plain some phenomena ......
We are willing to bury the reality of the cruelty and injustice, we are our parents, our elders could not understand some of the practice of life, we do not understand why they like to do ah. it is our wish too much too young to bury social e_perience. attitude of life when we are not deep.
Down we love fantasy, love to dream of behavior, we need to do one for the people and human progremake a difference. to our ac Tions to prove that we have!
Facing this audience on the stage, I have the e_citing feeling of participating in the march of history, for what we are facing today is more than a mere competition or contest. It is an assembly of some of China's most talented and motivated people, representatives of a younger generation that are preparing themselves for the coming of a new century. I'm grateful that I've been given this opportunity, at such a historic moment, to stand here as a spokesman of my generation and to take a serious look back at the past 15 years, a crucial period for every one of us and for this nation as well.
Though it is only within my power to tell about my personal e_perience, and only a tiny fragment of it at that, it still represents, I believe, the root of a spirit which has been essential to me and to all the people bred by the past 15 years.
In my elementary years, there was a little girl in the class who worked very hard but somehow could never do satisfactorily in her lessons.
The teacher asked me to help her, and it was obvious that she e_pected a lot from me. but as a young boy, restless, thoughtless, I always tried to evade her so as to get more time to enjoy myself.
One day before the final e_am, she came up to me and said, "Could you please e_plain this to me? I want very much to do better this time. " I started e_plaining, and finished in a hurry. Pretending not to notice her still confused eyes, I ran off quickly. Nat surprisingly, she again did very badly in the e_am. And two months later, at the beginning of the new semester, word came of her death of blood cancer. No one ever knew about the little task I failed to fulfill, but I couldn't forgive myself. I simply couldn't forget her eyes, which seem to be asking, "Why didn't you do a little more to help me, when it was so easy for you? Why didn't you understand a little better the trust placed in you, so that I would not have to leave this world in such pain and regret?"
I was about eight or nine years old at that time, but in a way it was the very starting point of my life, for I began to understand the word "responsibility" and to learn to always do my duties faithfully and devotedly, for the implications of that sacred word has dawned on me: the mutual need and trust of people, the co-operation and inter-reliance which are the very foundation of human society.
Later in my life, I continued to e_perience many failures. But never again did I feel that regret which struck me at the death of the girl, for it makes my heart satisfied to think that I have always done everything in my power to fulfill my responsibilities as best I can.
As I grew up, changed and improved by this incident and many other similar ones, I began to perceive the changes taking place around me and to find that society, in a way, was in its formative years like myself. New buildings, new commodities and new fashions appear every day.
New ideas, new information, new technologies. People can talk with each other from any corner of the earth in a matter of seconds. Society is becoming more competitive.
