Carrots

CARROTS
Like other orange and yellow vegetables high in beta-carotene, carrots have been associated with lower rates of heart disease, cancer, and other disorders. In Oriental medicine, they are especially good for the lungs and large intestine and their sweet taste nourishes the pancreas. See Carotenoids, Vegetables.

• Carrots Associated with Lower Cervical Cancer - An Italian case-control study found that 191 women with invasive cervical cancer consumed less carrots and green vegetables than healthy women. Both foods were highly protective, with almost a fivefold increased risk associated with eating carrots less often than once a week or green vegetables less often than once a day.

• Carrots Reduce Risk of Breast Cancer - Carrots may help protect against breast cancer. Scientists at the National Institute of Environmental Health Sciences reported that eating carrots more than twice weekly, compared with no intake, was associated with 44 percent less breast cancer in a case-control study of 13,000 women conducted in Maine, Massachusetts, New Hampshire, and Wisconsin.
Meanwhile, in a study of the effect of 26 types or groups of vegetables and fruit on cancer development, Italian researchers reported that most vegetables protected against cancer of the colon and rectum, but only carrots lowered breast cancer risk.

• Carrots Protect Against Vulvar Cancer - Italian researchers reported that in a study of 125 women with invasive vulvar cancer and 541 controls in the Milan area, women who ate high amounts of carrots had about half the risk of contacting the disease.

• Carrots Protect Against Lung Cancer - In a case-control study involving over 300 women in Spain, scientists found that intake of yellow/orange vegetables, principally carrots, reduced the risk of lung cancer by almost two-thirds.

• Carrots Improve Liver Function - In laboratory studies, scientists in India reported that carrot extracts reduced acute liver damage in mice.

Carotenoids

CAROTENOIDS
Carotenoids are a family of nutrients in plants that are associated with increased health and less disease. Altogether there are nearly 600 types of carotenoids, of which beta-carotene, which makes up about 25 percent of edible varieties, is the most well known. It is efficiently converted by the body into vitamin A and as an antioxidant blocks free radicals which can damage cell membranes and protects against cancer.
In the 1980s, dozens of studies reported that increased intake of beta carotene was associated with a decreased risk of many cancers of the respiratory and digestive tracts, including lung, oral cavity, throat, stomach, colon, and rectum. Taking beta-carotene in the form of supplements, however, has been linked with increased incidence of lung cancer. Scientists strongly recommend that the carotenoids be taken in whole foods. See Immune Function, Lung Cancer, Macular Degeneration, Olestra, Polyps, Smoking, Vegetables.

• Carotenoid Rich Vegetables Protect Against Heart Disease - In a study of middle aged men at risk of heart disease, those who had the highest carotenoid levels in their blood were one third less likely to suffer a heart attack. Nonsmokers consistently show the strongest benefits. In another study of nurses, Boston researchers reported that those who ate five or more servings of carrots a week had 68 percent less strokes than those who ate one or less a month.

Apple

APPLE
As part of a balanced diet, apples can help keep away serious illness. High in flavonoids, pectins, and other phytochemicals, apples can help protect against cardiovascular disease and certain cancers, especially lung and colon.

• Apples Protect Against Lung Cancer - In a study of flavonoid intake and risk of lung cancer in Finland, scientists reported that of all major dietary flavonoid sources, the consumption of apples protected men and women better than other fruits and vegetables. Those who ate the highest amount of apples had 58 percent lower lung cancer than those who ate the lowest.
