Should It Really Be "10-a-Day"?
Although some earlier scientific studies failed to find a link between
eating vegetables and fruits and reduced risk for some types of cancers, more
recent ones are reversing that trend.
For example, a recent study in Northern Italy suggested that raw vegetables
may help protect against both breast and prostate cancer. Other research has
indicated that cruciferous vegetables (like broccoli, cauliflower, and cabbage)
may play a role in reducing breast-cancer risks in premenopausal women. One of
the benefits of cruciferous veggies may be their abundant supply of
isothiocyanates. These phytochemicals may help increase certain enzymes that
detoxify cancer-promoting chemicals.
While we're on the subject of broccoli, another phytochemical in this
vegetable recently made medical news. A report from the University of Illinois
at Urbana-Champaign was the first to show how the isothyiocyanate found in
broccoli, brussels sprouts, and kale -- called sulphoraphane -- can block late
stages of the cancer process. Using human breast cancer cells in the lab,
researchers were able to hinder the growth of the cancer -- much like certain
Various fruits and vegetables have also been scientifically linked with
prevention of colon, mouth, esophageal, lung, and stomach cancers. Population
studies have repeatedly suggested that certain types of produce -- dark green
vegetables; tomatoes; citrus; cruciferous vegetables such as broccoli and
cabbage; and carotene-rich ones such as carrots and cantaloupe -- reduce
overall cancer risk.
More and more studies are being done all the time. But obviously, fruits and
vegetables are very important to our health in general. It's hard to argue with
those food choices!
Bottom line: Strive to eat 10 servings (about 1/2 cup is a serving)
of fruits and vegetables a day, choosing carotene-rich produce, dark green
vegetables, cruciferous vegetables, tomatoes, and citrus when possible.
Specific Nutrients or Foods with an Anti-Cancer Connection
Flaxseed. This sesame-like seed has three things
going for it. Ground flaxseeds contain soluble fiber, alphalinolenic acid (a
form of healthy omega-3 fatty acid), and are the richest source of lignans
(phytoestrogens that function like antioxidants) on the planet. These are not
to be confused with flaxseed oil, which contains just the oils from flaxseed,
not the fiber or plant estrogens.
