Dietary fats reduce effectiveness of antioxidants like vitamin C

The anti-cancer benefits of vitamin C can be dramatically reduced by intake of dietary fats, according to a new study conducted at the University of Glasgow. The results of the study, which simulated what happens in the human stomach, were presented earlier this month at the annual meeting of the Society of Experimental Biology in Glasgow.

Researchers investigated how vitamin C affects the acidification of nitrite in the stomach. This acidification can lead to production of potentially carcinogenic N-nitroso compounds related to stomach cancer. According to the European School of Oncology, stomach cancer is the fourth most frequent cancer worldwide with 800,000 new cases diagnosed every year.

Carcinogenic compounds form when nitrite, found in saliva, and nitrate in some foods mix with stomach acids. Ascorbic acid (the active component of vitamin C) protects against the formation of these compounds. The study revealed vitamin C inhibited conversion to carcinogenic compounds by approximately 99.7 percent.

Notably, the research team also found when dietary fats were added to the mix, the antioxidant properties of vitamin C were neutralized, and the carcinogenic N-nitrosamine was formed.

"These results indicate that the presence of lipid can markedly alter the protective effects of antioxidants with respect to potentially carcinogenic nitrosative chemistry occurring in the human stomach, and illustrate how a diet rich in lipids can directly influence gastric biochemistry," said lead author Emilie Combet.

Lipids are substances of the fat group and are insoluble in water. While some lipids are necessary for storing energy, others include a class of harmful trans-fatty acids found in hydrogenated oils and partially hydrogenated oils common not only in fast food but also in many products found on grocery store shelves -- including dairy products and meat. This year major cities in the U.S. are taking steps to ban trans-fats in food served in restaurants.

"This research helps explain why high-fat diets that focus on dairy products, meat products, and processed foods are so strongly correlated with cancer and heart disease," said Mike Adams, author of Grocery Warning: How to Identify and Avoid Dangerous Food Ingredients. "Many superfoods perform best when consumed during a meal that has no fats," Adams said, "But don't forget to consume healthy, plant-based fats later. Omega-3 fatty acids are essential for a healthy heart."

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.
