Guest guest Posted August 29, 2005 Report Share Posted August 29, 2005 Meta eNewsHere is a recent commentary by Metagenics on Soy(and incidentally on fructose). Since a discussion on soy was had on cha recently, i thought I would fw this as another review of this significant matter. Ann p.s. I have no financial interest in this company and do not mean this as a promotional of any product. ...BULLETIN August 19, 2005 Vol. III, No. VII Exclusively for Healthcare Practitioners from Metagenics, Inc.-Your Natural Health Sciences Resource ----------------------------- MEDICAL FOODS - Separating Fact from Fiction - Reliable Solutions to Chronic Conditions Medical foods represent a rapidly increasing segment of the nutritional products market. The appeal of medical foods stems from their application as safe and effective therapeutic agents. Each year, medical foods are used by hundreds of thousands of patients to manage complex chronic conditions such as dysglycemia, inflammation, and altered body composition. Under the direction of the Food and Drug Administration (FDA), the following criteria define medical foods: a.. A combination of micronutrients, macronutrients, and other food factors combined to nutritionally manage specific physiological health challenges or diseases. b.. Recognized scientific principles support the nutritional composition for the specific condition. c.. Medical foods are administered under the supervision of a physician or licensed healthcare practitioner. Article Summary a.. Medical foods are therapeutic agents that help manage health challenges or diseases b.. Fructose is a natural form of sugar that should not be confused with high fructose corn syrup (HFCS) c.. A preponderance of evidence supports the health benefits of soy foods d.. Metagenics has a 14-year history of creating superior medical foods The purpose of this paper is to clarify two of the most misunderstood claims related to this class of natural therapeutic agents and separate fact from fiction. Unfounded Allegations on Medical Food Ingredients Myth: Fructose ( " fruit sugar " ) is a harmful food ingredient that promotes blood sugar dysregulation and obesity. Fact: Fructose is a natural form of sugar that should not be mistaken as high fructose corn syrup(HFCS)-a modified form of corn starch. These are very different substances. Fructose is known to have the lowest glycemic index (GI) of any simple sugar. When consumed as part of a healthy diet, no adverse effects have been associated with modest fructose intake. Furthermore, research demonstrates that moderate levels of fructose can improve insulin sensitivity and glycemic control in both healthy and diabetic individuals.2 For more information on fructose, click here How Much Fructose is Safe? Comparing Medical Foods to Apples Fructose is a natural sweetener found in honey, fruits, berries, and vegetables. Fructose is among the most commonly consumed simple sugars-along with glucose (found commonly in candy, gum, and jams) and sucrose (table sugar). For example, an apple contains an average of 15 to 20 grams of sugar, the majority of which is fructose. Item: Fructose Content: Apple 12-18 grams UltraInflamX® Original 0 grams UltraInflamX® Chocolate Orange 2.2 grams UltraMeal Plus® Vanilla 15 grams UltraMeal Plus® Chocolate 15 grams UltraGlycemX® Original 2 grams UltraGlycemX® Chocolate 3 grams Myth: Soy is an unhealthy and incomplete protein source that offers few health benefits. Fact: A preponderance of evidence supports the benefits of soy foods-particularly soy protein and isoflavones-for the promotion of overall health. Many of the negative articles on soy only focus on one particular study instead of providing a balanced review of the extensive research on soy. Some soy controversies have arisen from research that is now viewed as outdated and/or irrelevant. Moreover, many articles do not clearly identify which components of soy were examined, for example, simply stating " soy protein " without mention to the amount of soy isoflavones present.3 The primary allegations against soy are addressed below: Is Soy Safe? Cumulative data gathered from epidemiological studies of Asian populations with high levels of soy consumption demonstrates that dietary soy consumption does not pose a substantial risk to overall human health. On the contrary, it has been shown that soy food consumption protects against a number of chronic diseases. How Much Soy Are Americans Eating? Various ranges of soy intake have been projected. While Asian populations consume an average of 10 to 50 grams of soy per day, Americans generally consume only 1 to 3 grams daily.4 Advantages of Soy Protein Isolates Soy protein isolates and concentrates are high quality, complete protein sources that are well tolerated in comparison to animal protein sources. In fact, soy protein can serve as the sole source of protein intake for both adults and children. While protein accounts for 20% to 30% of the weight for most legumes, it accounts for roughly 35% to 38% of the weight for soybeans. The amount of protein varies among different soy products: Soy flour 50% protein Soy concentrate 70% protein Soy isolate 90% protein Is Soy a Complete Protein? Soy is a nutritionally complete protein that offers an unusually well-rounded amino acid profile for a plant protein. Soy contains adequate quantities of all essential amino acids necessary for the building and maintenance of human tissue.5 For many people-especially those with hormone imbalances or high blood lipid levels and other cariovascular issues-soy provides a superior, lowfat protein source. Does Soy Prevent Mineral Absorption? Soy products provide a good balance of nutrients, including minerals. Soy proteins with reduced levels of phytic acid, a substance found in high fiber foods that can bind minerals in the digestive tract, will have little impact on mineral status. Soy protein isolates utilized in Metagenics medical foods are produced in a manner to reduce phytic acid levels. Does Soy Have a Negative Impact on Thyroid Function? Well-designed human clinical trials have demonstrated that soy has an insignificant effect on thyroid hormone values in healthy individuals.6,7 What Health Benefits Does Soy Offer? Soy has been the subject of extensive research and has been shown to positively impact:8-13 a.. Cardiovascular function b.. Cholesterol and triglyceride levels c.. Estrogen levels d.. Breast health e.. Prostate health f.. Bone density In conclusion, due to its history of safe use, support by government and scientific leaders, and substantial positive epidemiological and experimental data, Metagenics supports the utilization of concentrated soy protein in certain medical food applications.

Metagenics-A Medical Foods Pioneer Although the FDA has allowed the manufacturing and labeling of medical foods to the benefit of people's health, not all products carrying this designation are created equal. To separate the imitators from the innovators, a good first step is to investigate the product's manufacturer. The Metagenics Advantage Metagenics medical food products are unique in that they have been subjected to extensive clinical testing in the Functional Medicine Research Center CenterSM-the research arm of Metagenics. Unlike copycat products, Metagenics medical food products are backed by numerous clinical studies and extensive peer-reviewed scientific support: a.. 18 medical food clinical trials (124 total patients) b.. Hundreds of individual case studies (341 total patients) c.. Hundreds of glycemic index and taste and tolerance studies (220 total patients) In the clinical realm, Metagenics medical foods have been in use for more than 14 years, delivering reliable patient outcomes again and again. The clinical reliability of Metagenics medical foods has led more healthcare practitioners to trust Metagenics more than any other professional nutritional company in the world. GMP-Certified Manufacturing Metagenics sets the standard for safety with stringent raw material selection and extensive testing for purity and quality. Going the extra mile, Metagenics products are manufactured in an NNFA, NSF, and TGA Good Manufacturing Practice (GMP) certified facility. References 1.. Truswell AS. Glycaemic index of foods.
