(WebMD) — Who would have thought that of all the brightly colored exotic offerings in the produce aisle — from curvy, golden-yellow peppers to inky purple eggplants — homely broccoli would become the superstar?
It’s true: In the category of most healthful vegetable, this cruciferous contender wins all the top honors.
This past February, when the American Journal of Clinical Nutrition published a paper that listed foods most likely to prevent colon cancer, what stood out? Broccoli. Scientists at the Harvard School of Public Health in Boston published an article in the same journal last October and noted that broccoli, along with spinach, helped to minimize risk for cataracts.
When another team of Harvard scientists looked at how diet might protect against stroke, broccoli’s benefits again came to the fore, in research published in the October 6, 1999 issue of the Journal of the American Medical Association.
Nutritious — and then some
When it comes to basic nutrients, broccoli is a mother lode. Ounce for ounce, boiled broccoli has more vitamin C than an orange and as much calcium as a glass of milk, according to the USDA’s nutrient database. One medium spear has three times more fiber than a slice of wheat bran bread. Broccoli is also one of the richest sources of vitamin A in the produce section.
But the real surprise is this vegetable’s potent cancer-fighting components.
At the Johns Hopkins University School of Medicine in Baltimore, Maryland, food chemist Dr. Paul Talalay has gone so far as to name his lab after “Brassica,” the genus that includes broccoli and cauliflower. Talalay and his team at the Brassica Chemoprotection Laboratory have discovered that broccoli is rich in substances called isothiocyanates — chemicals shown to stimulate the body’s production of its own cancer-fighting substances, called “phase two enzymes.” According to Talalay, these enzymes, in turn, neutralize potential cancer-causing substances before they have a chance to damage the DNA of healthy cells.
To test broccoli’s cancer-fighting power, Talalay fed rats hearty servings of the vegetable for a few days and then exposed them to a potent carcinogen known to trigger a form of breast cancer in the animals. Broccoli-munching rats were half as likely to develop tumors as animals on standard chow, according to results published in the April 1994 Proceedings of the National Academy of Science.
“Even those rats that did develop cancer ended up with fewer and smaller tumors, which is an important advantage in itself,” says Talalay.
More recently, scientists at Tokyo’s Graduate School of Agriculture have shown that isothiocyanates can block the growth of melanoma skin cancer cells, according to findings published in 1999 in the journal “Nutrition and Cancer.”
Good news for broccoli haters
If you don’t like broccoli, take heart: In 1997, Talalay and his researchers at Hopkins discovered to their surprise that broccoli sprouts, the week-old seedlings of the mature plant, are exceptionally rich in a form of isothiocyanate called sulforaphane — 10 to 100 times as rich as broccoli itself, in fact. More and more markets now carry the tender shoots, which are delicious on sandwiches and salads.
And keep in mind that broccoli is just one of many members of the cruciferous vegetable family, which includes cauliflower, kale, cabbage, Brussels sprouts, and bok choy — all of which appear to help protect against cancer.
When scientists at the World Cancer Research Fund reviewed 206 human and 22 animal studies, they found convincing evidence that cruciferous vegetables in general lowered risk for many forms of the disease, including tumors of the stomach, esophagus, lung, oral cavity and pharynx (throat), endometrium (lining of the uterus), pancreas, and colon.
How to enrich your diet
Need ideas for adding more of these vegetables to your diet?
Cauliflower makes a delicious addition to pasta primavera. Use penne pasta and you can boil the cauliflower and the noodles together — both require the same amount of cooking time.
Chopped red cabbage is a great addition to salads or chili. And if you’re not familiar with kale, try it in the savory Portuguese soup called caldo verde: Peel and finely chop two pounds of potatoes and boil for two minutes. Then add one bunch of chopped kale (about 6 to 8 cups) and cook for two more minutes. Season with a little salt and a splash of olive oil and you’re ready to eat.

We’re told that an apple a day keeps the doctor away, but what exactly are the health benefits of apples? Here are ten reasons to heed the advice of that old proverb.
Bone Protection
French researchers found that a flavanoid called phloridzin that is found only in apples may protect post-menopausal women from osteoporosis and may also increase bone density. Boron, another ingredient in apples, also strengthens bones.
Asthma Help
One recent study shows that children with asthma who drank apple juice on a daily basis suffered from less wheezing than children who drank apple juice only once per month. Another study showed that children born to women who eat a lot of apples during pregnancy have lower rates of asthma than children whose mothers ate few apples.
Alzheimer’s Prevention
A study on mice at Cornell University found that the quercetin in apples may protect brain cells from the kind of free radical damage that may lead to Alzheimer’s disease.
Lower Cholesterol
The pectin in apples lowers LDL (“bad”) cholesterol. People who eat two apples per day may lower their cholesterol by as much as 16 percent.
Lung Cancer Prevention
According to a study of 10,000 people, those who ate the most apples had a 50 percent lower risk of developing lung cancer. Researchers believe this is due to the high levels of the flavonoids quercetin and naringin in apples.
Breast Cancer Prevention
A Cornell University study found that rats who ate one apple per day reduced their risk of breast cancer by 17 percent. Rats fed three apples per day reduced their risk by 39 percent and those fed six apples per day reduced their risk by 44 percent.
Colon Cancer Prevention
One study found that rats fed an extract from apple skins had a 43 percent lower risk of colon cancer. Other research shows that the pectin in apples reduces the risk of colon cancer and helps maintain a healthy digestive tract.
Liver Cancer Prevention
Research found that rats fed an extract from apple skins had a 57 percent lower risk of liver cancer.
Diabetes Management
The pectin in apples supplies galacturonic acid to the body which lowers the body’s need for insulin and may help in the management of diabetes.
Weight Loss
A Brazilian study found that women who ate three apples or pears per day lost more weight while dieting than women who did not eat fruit while dieting.

According to the World’s Healthiest Foods, grapefruit is a powerhouse of nutrition and an excellent source of vitamin C, dietary fiber, vitamin A, potassium, folate, vitamin B5, and phytochemicals such as liminoids and lycopene:
- Vitamin C helps to support the immune system and fight free radical damage.
- Lycopene, a carotenoid phytonutrient, appears to have anti-tumor activity.
- Limonoids inhibit tumor formation by promoting the formation of a detoxifying enzyme.
- Pectin is a form of soluble fiber that has been shown in animal studies to slow the progression of atherosclerosis.
In addition, studies have revealed that eating grapefruit or drinking grapefruit juice, reduces the risk of kidney stones, protects against lung and colon cancer, significantly increases the production and activity of liver enzymes responsible for eliminating toxins from the body, and helps repair damaged DNA in human prostate cancer cells.
