Below is some advice on how to prevent cancer:
                                          8 Ways to Avoid Cancer in Your Life
1. Eat Blueberries
Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important
colon(结肠) cancer-fighting prosperities. But wait, it gets better. Blueberries also offer a large dose of
vitamins C (14 milligrams per cup). So at breakfast, try to take in a cup and a half of blueberries in your
cereal or yogurt, or mixed with other berries.
2. Drink Pomegranate(石榴)Juice
The deep red juice of the pomegranate contains polyphenols, isoflavones and ellagic acid, which together
create a powerful anticancer mixture. Most recently, researchers from the University of Wisconsin at
Madison has discovered that 16 ounces of pomegranate juice per day also may inhibit the growth of lung
cancer.
3. Relax
Feeling stressed or worried? Find ways to relax and you may reduce your chances of developing cancer.
Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high
levels of worry died during the study period. Only 20 percent of the optimists died before the study were
completed, while 34 percent of the extremely anxious men died of some type of cancer. Instead of
stressing about the past or future, focus on the present and relax!
4. Take Selenium(硒)
Selenium is well known for its cancer-fighting properties. In a study of almost 1,000 men, researchers
from the Journal of the National Cancer Institute found that when men with the lowest initial levels of
selenium in their bodies received a daily supplement over a 4 year period, they cut their prostate(前列腺) cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so
monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.
5. Eat Sushi(寿司)
Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted
seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high
in protein- a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. So don't skimp
(节省)on the Sushi!
6. Enjoy the Outdoors
Vitamin D causes early death of cancer cells. A study published in the American Journey of Clinical
Nutrition reported that women who supplemented their diets with 1,000 international. Units of vitamin
D every day had a 60 percent to 77 percent lower incidence of cancer ever a four-year period that did
women taking a placebo(无效对照剂). Experts recommend supplementing your fun in the sun with
1,100 to 2,000IU of vitamin D each day.
7. Breathe Clean Air
There's no question that secondhand smoke kills. A recent American Journal of Public Health study
showed that nonsmokers working in smoky places had three times the amount of carcinogen(致癌物质)
in their urine(尿) than nonsmokers working in smoke-free locations. What's worse, their levels of the
carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces,
bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.
8. Break a Sweat
Even a small amount of exercise can offer major cancer-fighting benefits. In a study of 29,110 men
published in the International Journal of Cancer, men who exercised just once a week had a percent
lower risk of metastasis(转移性) prostate cancer than men who didn't work out at all. The better the
frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study.
