A bowl full of bright green steamed broccoli. You say either "Yum!" -- or
"Where's the double cheeseburger?" But you know the broccoli is good for you,
especially sans melted cheese. The question is, how good? And more to the
point, can it -- or any food -- help prevent disease, such as cancer?
The answer is yes -- some foods do show cancer-fighting properties, though
no one is yet able to say one food or another can stop cancer in its tracks.
Still, a body of research suggests an overall healthy diet filled with colorful
fruits and vegetables is the key to skirting heart disease, diabetes, and
possibly cancer, too.
Children with cancer need information that is right for their age.
Studies show that children with cancer want to know about their illness and how it will be treated. The amount of information a child wants depends in part on his or her age. Most children worry about how their illness and treatment will affect their daily lives and the people around them. Studies also show that children have less doubt and fear when they are given information about their illness, even if it is bad news.
In fact, scientists know more about what not to eat -- processed meats,
salty foods, sugary drinks, huge helpings of red meat -- than which fruits and
vegetables to pile on your plate. But they do know those foods matter.
A comprehensive review of thousands of studies on diet, physical activity,
and weight conducted for the World Cancer Research Fund and the American
Institute for Cancer Research pointed to the benefits of eating mostly foods of
plant origin. Foods such as broccoli, berries, and garlic showed some of the
strongest links to cancer prevention.
They're low in calories and fat and power-packed with phytochemicals and
antioxidants that may help reduce your cancer risk.
Antioxidants, Phytochemicals, and Cancer
You've heard of antioxidants, such as vitamin C, lycopene, and
beta-carotene, which are in many fruits and vegetables. Studies suggest that
people who eat meals that are rich in fruits and vegetables have a lower risk
of cancer. A variety of chemicals from plants known as phytochemicals also seem
to protect cells from harmful compounds in food and in the environment, as well
as prevent cell damage and mutations, says Jed W. Fahey, ScD, MS, a faculty
research associate at Johns Hopkins University School of Medicine, who studies
how cruciferous vegetables help protect against disease.
A diet that could ward off cancer really doesn't look that different from
the healthy foods you should be eating anyway, says Wendy Demark-Wahnefried,
PhD, RD, a professor of behavioral sciences at the University of Texas M.D.
Anderson Cancer Center in Houston. That means plenty of fruits and vegetables,
as well as whole grains and lean meat or fish.
