A new study conducted by Ohio State University researchers has documented the power of black raspberries to prevent the development of tumors in the esophagus and colon. The study's findings were presented at the March 2007 national meeting of the American Chemical Society.

Gary Stoner, Ph.D., a professor of internal medicine at Ohio State University, led the study. Stoner and his co-workers prepared a powdered, freeze-dried extract from black raspberries then gauged its effect on rats that had been exposed to a cancer-causing substance. The research team measured the prevalence of malignant tumors. Compared to a control group, the rats fed black raspberry extract showed a 60 percent reduction in tumors of the esophagus and up to an 80 percent reduction in colon tumors.

"That's a much higher reduction than I thought we'd see," Stoner said, "This suggests that berries bind up a good portion of free radicals, preventing them from causing damage in the body."

Black raspberries are rich in vitamins A, C, E, and folic acid and contain the minerals selenium, zinc, and calcium. In addition, black raspberries have a higher content of anthocyanins than most other berry types, as well as phenols, such as ellagic, coumaric and ferulic acid. All of these substances are recognized as "chemopreventive agents," Stoner said.

"We do know from epidemiologic studies that vegetable and fruit consumption is protective against cancer and, from our work, we would suggest that berries be one of those helpings, at least two or three times a week," said Stoner.

Clinical trials are underway to examine the potential of black raspberries to prevent esophageal and colon cancer in humans. Stoner and his team have begun analyzing the effects of the fruit in people with Barrett's esophagus (a condition of the esophagus that increases risk of esophageal cancer) and precancerous colon polyps. Preliminary results show the berries are well tolerated at doses similar to those used in animals.

About the author:Mike Adams (aka the "Health Ranger") is a best selling author (#1 best selling science book on Amazon.com) and a globally recognized scientific researcher in clean foods. He serves as the founding editor of NaturalNews.com and the lab science director of an internationally accredited (ISO 17025) analytical laboratory known as CWC Labs. There, he was awarded a Certificate of Excellence for achieving extremely high accuracy in the analysis of toxic elements in unknown water samples using ICP-MS instrumentation. Adams is also highly proficient in running liquid chromatography, ion chromatography and mass spectrometry time-of-flight analytical instrumentation.

Adams is a person of color whose ancestors include Africans and Native American Indians. He's also of Native American heritage, which he credits as inspiring his "Health Ranger" passion for protecting life and nature against the destruction caused by chemicals, heavy metals and other forms of pollution.

Adams is the founder and publisher of the open source science journal Natural Science Journal, the author of numerous peer-reviewed science papers published by the journal, and the author of the world's first book that published ICP-MS heavy metals analysis results for foods, dietary supplements, pet food, spices and fast food. The book is entitled Food Forensics and is published by BenBella Books.

In his laboratory research, Adams has made numerous food safety breakthroughs such as revealing rice protein products imported from Asia to be contaminated with toxic heavy metals like lead, cadmium and tungsten. Adams was the first food science researcher to document high levels of tungsten in superfoods. He also discovered over 11 ppm lead in imported mangosteen powder, and led an industry-wide voluntary agreement to limit heavy metals in rice protein products.

In addition to his lab work, Adams is also the (non-paid) executive director of the non-profit Consumer Wellness Center (CWC), an organization that redirects 100% of its donations receipts to grant programs that teach children and women how to grow their own food or vastly improve their nutrition. Through the non-profit CWC, Adams also launched Nutrition Rescue, a program that donates essential vitamins to people in need. Click here to see some of the CWC success stories.

With a background in science and software technology, Adams is the original founder of the email newsletter technology company known as Arial Software. Using his technical experience combined with his love for natural health, Adams developed and deployed the content management system currently driving NaturalNews.com. He also engineered the high-level statistical algorithms that power SCIENCE.naturalnews.com, a massive research resource featuring over 10 million scientific studies.

Adams is well known for his incredibly popular consumer activism video blowing the lid on fake blueberries used throughout the food supply. He has also exposed "strange fibers" found in Chicken McNuggets, fake academic credentials of so-called health "gurus," dangerous "detox" products imported as battery acid and sold for oral consumption, fake acai berry scams, the California raw milk raids, the vaccine research fraud revealed by industry whistleblowers and many other topics.

Adams has also helped defend the rights of home gardeners and protect the medical freedom rights of parents. Adams is widely recognized to have made a remarkable global impact on issues like GMOs, vaccines, nutrition therapies, human consciousness.

In addition to his activism, Adams is an accomplished musician who has released over a dozen popular songs covering a variety of activism topics.
