Seguridad de Stevia - Stevia Safety
I found this article - however in spanish - explaining potential risks
of extracts of Stevia Rebaudiana Bertoni. Think you might be interested reading it also: http://www.leetu.com/2010/05/15/efec...ios-de-stevia/ Encontré este artículo "Seguridad de Stevia - Efectos Secundarios de Stevia" cuando busqué información sobre Stevia y sus potenciales efectos secundarios. Me parece muy interesante para las personas que piensan utilizar este edulcorante en el futuro o ya están utilizándolo. |

Spanish to English translation Stevia Side Effects Want your juice with or without Stevia? That was the question of a girl in the cafe of a sauna in Cochabamba, where I relaxed the weekend and was surprised when I said "no thanks." What we know about this natural sweetener is now also produced in Bolivia? Reading the labels on the bottles with a white powder called Stevia in supermarkets, the common sugar substitute is a wonder that has a variety of positive properties, including increased glucose tolerance, reduced hypertension, cure of osteoporosis, caries prevention, natural source of antioxidants, etc. What is Stevia? The plant Stevia rebaudiana Bertoni, commonly called Stevia was first mentioned by the Spanish physician and botanist Pedro Jaime Esteve (1500-1556) who found in the north-east of the territory now called Paraguay. Guarani Indians of this area as in southern Brazil using "ka'a he'ê" ("sweet leaf"), named in Guaraní, hundreds of years as a sweetener in yerba mate, and several tribes reported the use of this plant in the control of fertility of women, applying concentrated Stevia infusions for prolonged periods. It is precisely this property contraceptive is discussed from the 70s until today in the scientific literature. The question is simple: Who wants to consume a sweetener that suddenly makes you barren? Stevia leaf contains a complex mixture of substances which have an intensely sweet taste, about 30-45 times sweeter than sucrose, refined sugar. To date, was isolated ten different chemical compounds responsible for the sweet taste of the plant: stevioside, rebaudioside A, B, C, D, E and F, sweets, Rubus and steviolbiosida. The highest concentration of the effect comes from Stevia Sweet and rebaudioside A. The commercial product is an extract from the leaves of Stevia is 250-300 times sweeter than refined sugar and only has about 0.2 calories per gram. The result of the chemical extraction of the plant is a product containing a minimum of 90-95% of stevia and / or rebaudioside A. Both sweet glycosides are chemically diterpenic glycosides, substances composed of two molecules of different types of sugar and a molecule called steviol. This serves as a "backbone" and is structurally similar to plant hormones and acid giberalina caurenóico (or caureno). Several studies show that partially glycosides are metabolized in the body releasing the sugar molecules and steviol. Is It Safe to Use Stevia instead of sugar? It is precisely this compound steviol, the backbone of Stevia sweeteners, which for many years called attention to toxicologists, because this substance demonstrated in studies with bacteria and cells, clear evidence of genotoxicity (for example, is capable of changing the genetic information). However, more recent studies with mice, rats and hamsters, indicated that it requires very high concentrations of steviol to initiate damage to DNA, the molecule of life containing all the genetic information. There are a variety of publications toxicological potential adverse effects of stevia extract and the results are not very consistent. In particular, the effect on fertility Stevia was the subject of controversy in the scientific world. A study published in 1968 by Professor Joseph Kuc Purdue University in Indiana, USA, initiated the discussion. Prof. Kuc detected a contraceptive effect by reducing the fertility of up to 79% of female rats when fed with high amounts of Stevia. While the outcome of this study was not confirmed by other scientific groups, in a study published in 1999 by Prof. Melis of the University of São Paulo confirmed the results of Kuc group and a decrease of sperm in male rats after application of high doses of Stevia glycosides. To reassure users of Stevia, in any study could confirm the carcinogenic or mutagenic effect on 'normal' application as a sweetener. Although adverse effects of Stevia never really been tested in humans, both the authorities in the United States, Canada and the European Union considered that Stevia extracts are not clear in the application as a tabletop sweetener, with the argument of the lack of long-term toxicological studies. Authorities in other countries like Japan, China and several Latin American countries have a different view and accepted the use of extracts of Stevia as a natural sweetener. In Japan, Stevia sweeteners are already available commercially since 1971 and there were no reported health problems associated with this sweetener. In the U.S., the Food and Drug Administration on (FDA) approved the use of extracts of Stevia as an ingredient in only a "nutritional supplement" but not as a tabletop sweetener. Only the glycoside Rebaudioside A in its pure form is considered as Generally Recognized as Safe Substances (GRAS in English) since December 2008. By contrast, stevia, the other lead compound Stevia extract, was not recognized as GRAS by the FDA. Both in Canada and the European Union (EU), the use of Stevia as a tabletop sweetener was rejected on the grounds that there was insufficient evidence to prove its safety. But now there is light at the end of the tunnel. A new view of the European Food Safety Authority (EFSA) that monitors sweeteners and their use, to remove trade products deemed hazardous to health. This institution published in April this year a document with an assessment of the toxicological information available to date. The result is that Stevia and Stevia extracts are considered safe when used as a tabletop sweetener - at least under certain conditions. EFSA recommends a maximum daily dose of 4 mg per kilogram of body weight, to be sure, the same maximum dose recommended by the World Health Organization according to a document published in 2008. In common words, an adult weighing 70 kg can consume 280 mg of an extract of Stevia with no risk to your health. Whereas Stevia extract is 250 times sweeter than table sugar, an adult can replace daily 70 grams of sugar per Stevia, equivalent to about 4-5 tablespoons or about 20 teaspoons of sugar. Because children have a lower body weight, the dose should be reduced in proportion to their weight. After the decision of the EFSA, which takes to the success of Stevia in the European market is only the final decision of the European Commission. For fans of Stevia is certain that being critical is never misplaced, because "natural" does not necessarily mean risk free. A good example is cocaine, extracted from the coca leaf. This drug is known is a 100% natural but with serious consequences in case of a non-controlled consumption.

Â* Â*€ Â*In Australia and New Zealand, prior to their October 2008 approval of all steviol glycoside extracts, stevia leaves could be sold as food.[27] Â* Â*€ Â*The European Food Safety Authority is conducting a safety review and is expected to permit stevia extract to be used in the EU member states in 2010.[28] Â* Â*€ Â*A report was issued from this review, on March 10, 2010, indicating that steviol glycosides are safe up to an Acceptable Daily Intake (ADI) of 4Â*mg/kgÂ*bodyÂ*weight/day, but that those levels are likely to be exceeded at the proposed maximum use levels in both adults and children.[29] [edit]http://en.wikipedia.org/wiki/Stevia Don't know what the purpose of the article is, but most agree that Stevia is safe. -- - Billy "Fascism should more properly be called corporatism because it is the merger of state and corporate power." - Benito Mussolini.http://www.youtube.com/watch?v=Arn3l....thirdworldtra veler.com/Zinn/HZinn_page.html The purpose is to resume the available information on the safety of stevia which proves that stevia is safe to use as a table top sweetener when not used in too large quantities. Furthermore, many of the claimed beneficial effects like cure of osteoporosis, caries prevention, reduction of tobacco and alcohol addiction, cardiovascular effects, etc. you can find on the labels of commercial Stevia extracts sales have not been confirmed at all in toxicological studies and are just sales pitches.

Nothing on line? Nothing sinister about studies. Think I'll wait for the movie. In any event, as I said, I use the plant, as people have been doing for centuries, not it's extract. -- - Billy "Fascism should more properly be called corporatism because it is the merger of state and corporate power." - Benito Mussolini. http://www.youtube.com/watch?v=Arn3lF5XSUg http://www.thirdworldtraveler.com/Zinn/HZinn_page.html |
