(NaturalNews) Phytonutrients, the chemicals that help plants defend against environmental challenges, such as damage from pests or ultraviolet light, appear to provide humans with protection as well. Mounting research shows their effectiveness in preventing and treating a range of conditions including everything from cancer and heart disease to diabetes and high blood pressure. But current law dictates that if anyone advertises health benefits without FDA approval, it is automatically considered an illegal health claim, even for everyday foods, such as walnuts.
Phytochemicals are thought to be responsible for much of the disease protection granted by diets high in fruits, vegetables, beans, cereals, and plant-based beverages such as tea and wine, according to a University of California, Davis report (http://chnr.ucdavis.edu/content/Fac...).
Although it has become widely accepted that a diet rich in fruits, vegetables, legumes, and grains reduces the risk of cancer, heart disease, and other illnesses, scientists have only recently begun researching the effects of the different phytonutrients those foods contain.
Previous evidence has come from observations of cultures that eat plant-based diets and have lower rates of certain types of cancer and heart disease. The relatively low rates of breast and endometrial cancers in some Asian cultures, for example, are credited partly to dietary habits. These cancers are much more common in the United States, possibly because the typical American diet is higher in fat and lower in fruits, vegetables, legumes and grains, according to American Cancer Society.
Many experts suggest that people can reduce their risk of cancer significantly by eating the foods that contain phytonutrients, according to American Cancer Society (http://www.cancer.org/Treatment/Tre...). Evidence shows that they may work by helping to prevent the formation of potential carcinogens, blocking the action of carcinogens on their target organs or tissue, or acting on cells to suppress cancer development.
Research suggests that flavonoids, the most diverse group of phytochemicals, may be a key phytochemical group that contributes to the reduced mortality rates observed in people consuming high levels of plant-based foods, according to the UC Davis report. In the Zutphen Elderly Study, myocardial infarction was found to decrease as falvonoid intake increased. Similarly, the Seven Countries Study, which compared the diets of men living in various Western countries including the U.S., suggested that consumption of flavonoids was responsible for 25 percent of the observed difference in mortality rates in the different countries.
University of Minnesota Hormel Institute researchers say phytonutrients could be used in effective cancer prevention therapy, so much so that they eventually aim to develop phytochemical-derived anticancer drugs, Dr. Sigang Dong told The Austin Daily Herald (http://www.austindailyherald.com/20...).
"In the future, personalized prevention methods using photochemical could have a crucial role in cancer prevention, especially in high-risk populations," Dong said. "We will continue our rigorous research in identifying molecular targets and aim for conducting human studies with phytocehemicals - this would provide the path for an enhanced approach to personalized cancer prevention."
