New discovery could reduce the health risk of high-fat foods

Chemical in red wine, fruits and vegetables counters unhealthy effects of high-fat foods

Just as additives help gasoline burn cleaner, a research report published in the January 2008 print issue of The FASEB Journal shows that the food industry could take a similar approach toward reducing health risks associated with fatty foods. These "meal additives" would be based on work of Israeli researchers who discovered that consuming polyphenols (natural compounds in red wine, fruits, and vegetables) simultaneously with high-fat foods may reduce health risks associated with these foods.

"We suggest a new hypothesis to explain polyphenols," said Joseph Kanner, senior author of the report. "For the first time, these compounds were demonstrated to prevent significantly the appearance of toxic food derivative compounds in human plasma."

For the study, six men and four women were fed three different meals consisting of dark meat turkey cutlets. One meal, the control, consisted of turkey meat and water. The second meal consisted of turkey meat with polyphenols added after cooking (one tablespoon of concentrated wine) followed with a glass of red wine (about 7 ounces). The third meal consisted of turkey meat with polyphenols added before cooking and then followed by a glass of wine.

At various points during the study, researchers took blood and urine samples to measure levels of malondialdehyde (MDA), a natural byproduct of fat digestion known to increase the risk for heart disease and other chronic conditions. The researchers found that MDA levels nearly quintupled after the control meal, while MDA was nearly eliminated after subjects consumed the meals with polyphenols.

"As long as deep fried candy bars are on menus, scientists will need to keep serving up new ways to prevent the cellular damage caused by these very tasty treats," said Gerald Weissmann, MD, Editor-in-Chief of The FASEB Journal. "This study suggests that the time will come where people can eat french fries without plugging their arteries."

	Recent Advances in Polyphenol Research (Volume 3) by Véronique Cheynier (Editor), Pascale Sarni-Manchado (Editor), Stéphane Quideau (Editor) Plant polyphenols are secondary metabolites that constitute one of the most common and widespread groups of natural products. They express a large and diverse panel of biological activities including beneficial effects on both plants and humans. Many polyphenols, from their structurally simplest representatives to their oligo/polymeric versions (also referred to as vegetable tannins) are notably known as phytoestrogens, plant pigments, potent antioxidants, and protein interacting agents.Sponsored by Groupe Polyphénols, this publication, which is the third volume in this highly regarded Recent Advances in Polyphenol Research series, is edited by Véronique Cheynier, Pascale Sarni-Manchado, and Stéphane Quideau (the current President of Groupe Polyphénols). Like their predecessors, they...
	Natural Antioxidants and Weight Loss: Anti-Obesity and Anti-Inflammatory Effects of Polyphenol Extracts from Fruits and Herbs (Journal of Personalized and Systems Medicine) by PharmTao.com Polyphenols are chemicals found in many plants. Polyphenols are usually antioxidants that can protect cells from oxidative damage caused by free radicals. Polyphenols include tannins, lignins, and flavonoids. Many polyphenols have anti-obesity activities and are beneficial for weight loss. Aging and obesity may lead to inflammatory and oxidative conditions. Inflammation and oxidative stress are also important pathological factors in obesity-related diseases such as diabetes, fatty liver, cardiovascular diseases, and cancer. Polyphenol extracts from fruits and herbs such as apples and green tea can inhibit inflammation, lower blood cholesterol and glucose levels, and reduce risks of heart diseases. These natural antioxidants can be used as dietary supplements without evident adverse...

	Recent Advances in Polyphenol Research (Volume 2) by Celestino Santos-Buelga (Author), Maria Teresa Escribano-Bailon (Author), Vincenzo Lattanzio (Author) Recent Advances in Polyphenol ResearchVolume 2Edited by Santos-Buelga, Escribano-Bailon and LattanzioPlant phenolics are secondary metabolites that constitute one of the most common and widespread groups of substances in plants. Polyphenols have a large and diverse array of beneficial effects on both plants and animals. For example they are famous as antioxidants, hormones, constituents of essential oils and natural neurotransmitters.Sponsored by Groupe Polyphenols, this publication, which is the second volume in this ground-breaking series, is edited by Celestino Santos-Buelga, Maria Teresa Escribano-Bailon, and Vincenzo Lattanzio, who have drawn together an impressive list of internationally respected authors, each providing cutting edge chapters covering some of the major topics of...
	Plant Polyphenols: Synthesis, Properties, Significance (Basic Life Sciences) by Richard W. Hemingway (Editor), Peter E. Laks (Editor) Written to provide critical reviews and summaries of current research on vegetable tannins and related plant phenolic compounds, this book highlights the biological and commercial significance of plant polyphenols. Leading scientists address a broad range of topics, including: enzymes in the biosynthesis of hydrolizable tannins - biosynthesis of flavenoids - gallic acid and its metabolites - plant phenolics as expressions of biological diversity - tannins and the qualities of wine - tannin structure and formulation of tannin-bases wood adhesives - leather manufacture with wattle tannins. Contributions to this volume are designed to benefit researchers from all disciplines who share a common interest in plant polyphenols and seek a better understanding of the importance of these...
	Flavonoids and Other Polyphenols, Volume 335: Methods in Enzymology, Vol. 335 by Lester Packer (Editor), Helmut Sies (Editor) The critically acclaimed laboratory standard for more than forty years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. Now with more than 300 volumes (all of them still in print), the series contains much material still relevant today-truly an essential publication for researchers in all fields of life sciences. This volume presents an extensive collection of new methodologies to aid progress in solving unanswered questions concerning the bioavailability and metabolism of flavonoids and polyphenols, their biochemical and molecular biological effects on cell regulation, and their effects on health. Major topics in...
	Polyphenols, Wine and Health - Proceedings of the Phytochemical Society of Europe, Bordeaux, France, 14--16 April 1999 (Proceedings of the Phytochemical Society of Europe, Volume 48) by Cathérine Chèze (Editor), Joseph Vercauteren (Editor), R. Verpoorte (Editor) In this book, the effect of nutritional habits and wine consumption on ageing and the main degenerative diseases (cardiovascular, cancer, Alzheimer's, etc.) are considered through the most relevant epidemiological and pharmacological studies. Newly isolated wine polyphenols and tannins are presented and their structures and in vitro biological properties are discussed that could strongly support the hypotheses that those molecules could insure beneficial health effects. This book will be of particular interest to people involved in problems of public health, but also in the wine industry or in wine making, as well as to physicians who are concerned by the difficult question of ageing and its related chronic diseases.

	Polyphenol: Webster's Timeline History, 1951 - 2007 by Icon Group International (Author) Webster's bibliographic and event-based timelines are comprehensive in scope, covering virtually all topics, geographic locations and people. They do so from a linguistic point of view, and in the case of this book, the focus is on "Polyphenol," including when used in literature (e.g. all authors that might have Polyphenol in their name). As such, this book represents the largest compilation of timeline events associated with Polyphenol when it is used in proper noun form. Webster's timelines cover bibliographic citations, patented inventions, as well as non-conventional and alternative meanings which capture ambiguities in usage. These furthermore cover all parts of speech (possessive, institutional usage, geographic usage) and contexts, including pop culture, the arts, social sciences...
