New discovery could reduce the health risk of high-fat foods
January 02, 2008Chemical 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."

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... |

Green Tea Extract, 400mg, 90 Veg Capsules (Standardized to 98% Polyphenols, 50% EGCG) by Our Health Co-op Green Tea Extract Green tea has been used for over 5,000 years for pain, digestion, mood maintenance, immune enhancement, detoxification, energy enhancement, and anti-aging. Unlike black and oolong teas, green tea does not endure a fermentation process and thus retains a host of beneficial phytonutrients. Specifically, green tea contains high concentrations of polyphenols ? plant-derived antioxidant compounds linked to health benefits ranging from immune system support to cardiovascular health. The primary polyphenols found in green tea include four catechins -- epigallocatechin gallate (EGCG) being the most potent and extensively researched. As an antioxidant, EGCG ranks up there with ascorbate (vitamin C) and glutathione, and helps move carcinogens and invading bacteria out of the body!... |
