Healthy diet may avert nutritional problems in head, neck cancer patients

Source: medicalxpress.com Author: University of Illinois at Urbana-Champaign At least 90 percent of head and neck cancer patients develop symptoms that affect their ability or desire to eat, because of either the tumor itself or the surgery or radiation used to treat it. These problems, called nutrition impact symptoms, have wide-ranging negative effects on patients' physical and mental health and quality of life. However, patients who eat foods high in antioxidants and other micronutrients prior to diagnosis may reduce their risks of developing chronic nutrition impact symptoms up to one year after being diagnosed with head or neck cancer, according to a recent study led by researchers at the University of Illinois. The scientists analyzed the dietary patterns of 336 adults with newly diagnosed head and neck cancers and these patients' problems with eating, swallowing and inflammation of the digestive tract. This painful inflammatory condition, called mucositis, is a common side effect of radiation treatment and chemotherapy. The mitigating effects of a healthy diet were particularly significant in people who had never smoked and in patients who were underweight or normal weight at diagnosis, who often experience the greatest eating and digestive problems during treatment, said Sylvia L. Crowder, the paper's first author. Crowder is a research fellow in the Cancer Scholars for Translational and Applied Research program, a collaborative initiative of the U. of I. and Carle Foundation Hospital in Urbana, Illinois. "While previous work has established that the presence of nutrition impact symptoms is associated with decreased food [...]

Berry Nutrition

Source: www.foodproductdesign.com Author: Marie Spano, M.S., R.D., Contributing Editor Nutritionally speaking, good things come in sweet—and tart—little packages. Research is discovering berries pack a nutritional punch due to their vitamin, fiber and antioxidant content. Botanically speaking, berries are indehiscent fruits (they don’t need to be opened to release their seeds) that ripen through the ovary wall. However, any small, edible fruit with multiple seeds is typically considered a berry. In addition to lending flavor and brilliant colors to a wide variety of dishes, all berries are packed with an array of antioxidants, nutrients and potential health benefits. Berries that are especially antioxidant-rich include fresh crowberries, bilberries, black currants, wild strawberries, blackberries, blueberries, goji berries, sea buckthorn, blueberries and cranberries. However, the antioxidant content of berries varies based on the geographical growing condition. And, while fresh berries are an excellent source of antioxidants, total phenol content drops during processing. In fact, processed berry jams and syrup contain approximately half the antioxidant capacity of fresh berries, and juices show the greatest loss of anthocyanins and tannins due to the removal of seeds and skin (Nutrition Journal, 2010; 9:3; Journal of Agricultural and Food Chemistry, Jan 13, 2012). Botanical berries Shiny, scarlet-colored cranberries are rich in vitamin C, loaded with antioxidants, including flavonoids, and score higher in their ORAC score than many other fruits ("Oxygen Radical Absorbance Capacity (ORAC) of Selected Foods—2007", USDA ARS). Cranberries are perhaps best known for the role their juice plays in the prevention of urinary tract infections (UTI) [...]

New anti-cancer components of extra-virgin olive oil revealed

Source: news.biocompare.com Author: staff Good quality extra-virgin olive oil contains health-relevant chemicals, 'phytochemicals', that can trigger cancer cell death. New research published in the open access journal BMC Cancer sheds more light on the suspected association between olive oil-rich Mediterranean diets and reductions in breast cancer risk. Javier Menendez from the Catalan Institute of Oncology and Antonio Segura-Carretero from the University of Granada in Spain led a team of researchers who set out to investigate which parts of olive oil were most active against cancer. Menendez said, "Our findings reveal for the first time that all the major complex phenols present in extra-virgin olive oil drastically suppress overexpression of the cancer gene HER2 in human breast cancer cells". Extra-virgin olive oil is the oil that results from pressing olives without the use of heat or chemical treatments. It contains phytochemicals that are otherwise lost in the refining process. Menendez and colleagues separated the oil into fractions and tested these against breast cancer cells in lab experiments. All the fractions containing the major extra-virgin phytochemical polyphenols (lignans and secoiridoids) were found to effectively inhibit HER2. Although these findings provide new insights on the mechanisms by which good quality oil, i.e. polyphenol-rich extra-virgin olive oil, might contribute to a lowering of breast cancer risk in a HER2-dependent manner, extreme caution must be applied when applying the lab results to the human situation. As the authors point out, "The active phytochemicals (i.e. lignans and secoiridoids) exhibited tumoricidal effects against cultured breast cancer cells [...]
