UNIVERSITY PARK, Pa. — Compounds found in purple potatoes may help kill colon cancer stem cells and limit the spread of the cancer, according to a team of researchers.
Baked purple-fleshed potatoes suppressed the growth of colon cancer tumors in petri dishes and in mice by targeting the cancer’s stem cells. Colon cancer is the second leading cause of cancer-related deaths in the U.S. and responsible for more than 50,000 deaths annually, according to the American Cancer Society.
Attacking stem cells is an effective way to counter cancer, according to Jairam K.P. Vanamala, associate professor of food sciences, Penn State and faculty member at the Penn State Hershey Cancer Institute.
“You might want to compare cancer stem cells to roots of the weeds,” Vanamala said. “You may cut the weed, but as long as the roots are still there, the weeds will keep growing back and, likewise, if the cancer stem cells are still present, the cancer can still grow and spread.”
By The U.S. Apple Association
Vienna, VA – Apples routinely top grocery lists for a variety of tasty reasons. Beyond the plethora of varieties and apple products to be enjoyed, apples pack a nutritious punch, providing a daily dose of health benefits.
“American consumers can be confident when eating or serving apples—whether organic or conventional—that they are enjoying a safe, nutritious, healthy and delicious home-grown food produced with pride by the U.S. apple growers and the apple industry,” said Wendy Brannen, Director of Consumer Health and Public Relations for U.S. Apple Association (USApple). “Apples are a super food found in every supermarket – and it is no wonder numerous health organizations, including the Surgeon General, the American Cancer Society and the American Dietetic Association, encourage greater consumption of fruits and vegetables—like apples and apple products.”
The U.S. Apple Association offers the following Delicious Dozen – 12 proven ways apples and apple products positively impact health, from head to toe and from the inside out:
1. Brain Health
Researchers from Cornell University found that apple nutrients protected brain neurons against oxidative damage. Such damage can contribute to neurodegenerative diseases, such as Alzheimer’s and Parkinson’s. The study highlighted the antioxidant quercetin as a principle compound responsible for the protective effect (Journal of Food Science, 2004, 69: S357-S360).
2. Symptoms of Alzheimer’s Disease
A University of Massachusetts-Lowell clinical trial showed that drinking apple juice significantly improved mood and behavior among a group of patients diagnosed with moderate-to-severe Alzheimer’s disease. Cornell University research also suggests that quercetin may be the compound in apples that protects brain cells against oxidative stress associated with Alzheimer’s.
3. Heart Health
An Ohio State University study recently found that eating an apple a day for four weeks lowered blood levels of oxidized LDL, the bad cholesterol, by 40 percent. A University of Florida study found eating two apples a day reduced LDL by 23%.
4. Respiratory System
A National Institutes of Health study reports that foods rich in fiber and flavonoids, found abundantly in apples, may reduce chronic productive cough and other respiratory symptoms (Am. J. Respir. Crit. Care Med, 2004, 170: 279-287).
5. Asthma
Research from the United Kingdom reports children of mothers who eat apples during pregnancy are much less likely to exhibit symptoms of asthma at age five. Apples were the only food found to have a positive association with a reduced risk of asthma among a variety of foods consumed and recorded (Thorax, 2007, 62:745-746).
6. Digestive Health
University of Denmark researchers discovered apples and apple products could boost intestinal health by increasing the numbers of good gut bacteria. The friendly bacteria in the intestines feed on apple pectin, a fiber found abundantly in apples (BMC Microbiology 2010, 10:13).
7. Bone Health
A study published in the November 2010 online edition of the American Journal of Clinical Nutrition suggests that older women who eat plenty of fruits, including apples and apple products, along with vegetables and whole grains, may have a lower chance of bone fractures than those not getting their fill.
8. Muscle Strength
A natural compound found in the apple’s skin, called ursolic acid, may help prevent muscle wasting that can result from aging and illness (Cell Metabolism, 2011, 13 (6): 627-638).
9. Weight Management or Weight Loss
State University of Rio de Janeiro researchers studying the impact of fruit intake on weight loss found that overweight women who ate the equivalent of three apples a day lost more weight on a low-calorie diet than women who didn’t eat the fiber-rich fruit (Nutrition, 2003, 19: 253-256).
10. Metabolic Syndrome
Adults who consume apples, apple juice and apple sauce are likely to have lower blood pressure and trimmer waistlines, resulting in a reduced risk of metabolic syndrome, a cluster of health problems related to diabetes and heart disease (Experimental Biology 2008 Poster (unpublished)).
11. Immune System
Soluble fiber, like apple pectin, may reduce the inflammation associated with obesity-related diseases and strengthen the immune system, according to a University of Illinois study (Brain, Behavior, and Immunity, 2010, in press/available online).
12. Certain types of Cancer, like Breast, Pancreatic, Colon or Liver, Prostate, and Colorectal
Apples are rich in antioxidants, especially quercetin, which have been identified to help inhibit cancer onset and cell proliferation. In one study, the more apples per day individuals ate, the less likely they were to develop colorectal cancer. The anti-cancer effect was seen even when an individual had a low total consumption of fruits and vegetables but consumed at least an apple a day (European Journal of Cancer Prevention, 2010, 19(1):42-47).
