"Consuming a diet high in vitamin B6 may reduce the risk of colorectal cancer in women, more specifically those who consume alcohol," said Susanna Larsson, MSc, study author with the Karolinska Institutet. "Inadequate vitamin B6 status may lead to the development of cancerous polyps in the colon, so it is important for women to maintain a normal to high intake of vitamin B6."

The second-leading cause of cancer deaths in the United States, it is estimated that more than 28,000 women with CRC will die in 2005. While increased vitamin B6 consumption decreases the risk of colorectal cancer, it does not eliminate the need for regular screening. Guidelines of multiple agencies and professional societies underscore the importance of colorectal cancer screening for all individuals 50 years of age and older.

Researchers at the Karolinska Institutet in Stockholm, Sweden and the Harvard School of Public Health used data from the Swedish Mammography Cohort to evaluate the association between long-term dietary vitamin B6 intake from food sources and colorectal cancer risk, and its modification by alcohol consumption. Nearly 67,000 women, aged 40 to 75 years, responded to a questionnaire that solicited data on diet, family history of CRC and use of dietary supplements. Researchers observed that alcohol consumption in women with low vitamin B6 intake resulted in higher risk of developing colorectal cancer and that increasing intake reduces this risk significantly.

The recommended daily dietary intake of vitamin B6 for non-pregnant women in the United States is 1.3 to 1.5 mg. Vitamin B6 is found in a wide variety of foods, including fortified cereals, beans, meat, poultry, fish, and some fruits and vegetables. It performs a wide variety of functions in the body, including helping to maintain normal blood glucose levels, fighting off infections and creating hemoglobin to ensure that oxygen gets to important organs and tissues.

While the study shows that consuming high amounts of vitamin B6 reduces the risk of colorectal cancer in women who drink, researchers say findings need further confirmation in large prospective cohort or intervention studies.

"These findings may have important implications for the prevention of colorectal cancer in women who consume alcohol because their vitamin B6 status can be easily improved through dietary modifications, vitamin supplementation and fortification," said Larsson.

About the Study

Researchers from the Harvard School of Public Health and the Karolinska Institutet in Stockholm, Sweden conducted a population-based study using the Swedish Mammography Cohort, a study established between 1987 and 1990 that takes into account information on diet, educational level, weight and height of 66,651 women aged 40 to 75 years living in two central Swedish counties. Researchers sought to evaluate the association between long-term dietary vitamin B-intake and colorectal cancer risk, and its modification by alcohol consumption in this cohort of women.

About the AGA

The American Gastroenterological Association ( AGA ) is dedicated to the mission of advancing the science and practice of gastroenterology. Founded in 1897, the AGA is the oldest medical-specialty society in the United States. The AGA's 14,000 members include physicians and scientists who research, diagnose and treat disorders of the gastrointestinal tract and liver. On a monthly basis, the AGA publishes two highly respected journals, Gastroenterology and Clinical Gastroenterology and Hepatology. The AGA's annual meeting is Digestive Disease Week, which is held each May and is the largest international gathering of physicians, researchers and academics in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery.

About Gastroenterology

Gastroenterology, the official journal of the AGA, is the most prominent journal in the subspecialty and is in the top one percent of indexed medical journals internationally. The journal publishes clinical and basic studies of all aspects of the digestive system, including the liver and pancreas, as well as nutrition. The journal is abstracted and indexed in Biological Abstracts, CABS, Chemical Abstracts, Current Contents, Excerpta Medica, Index Medicus, Nutrition Abstracts and Science Citation Index.

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.
