Sugar for years has been seen as the cause of obesity, say Canadian researchers. Fructose, which is natural sugar found in fruits and vegetables.
Recent studies have detected that natural sugar in fruits and vegetables is not "toxic" does not cause weight gain unlike any other carbohydrates when not consumed in excess, fructose does not affect blood pressure and even can help control blood sugar when it is normally consumed without excess. According to studies in which different sources of carbohydrates are compared.
Studies revealed the following:
Fructose had no significant effect on body weight according to an analysis of individuals with controlled diet. Excess calories from any type of carbohydrates contributes to weight gain.
Fructose had no adverse effect on blood pressure compared with other types of carbohydrate obtained in an analysis of 15 individuals.
10 grams of fructose per serving would help the glycemic control (control of blood sugar), obtained by analysis of six individuals.
According to recent studies warn about high fructose that are found in soft drinks (more than the average consumer) which increases the body weight control. However, weight gain is due if the extra calories consumed not only as such fructose.
The full study results appear in the journal British Medical Journal of Nutrition, the authors of these findings were Dr. John L. Sievenpiper, MD, Ph.D., Russel J. de Souza, ScD, RD, and David Jenkins, MD, Ph.D., St. Michael's Hospital in Toronto, Ontario, Canada.
Fructose is unpopular among the ingredients of some processed foods because it is known as corn syrup, high fructose, which is only 45% glucose and 55% fructose, Note that in previous studies, researchers concentrated in only fructose (natural) and not corn syrup high fructose.
The research was recently presented at the fact a controversial publication by Robert Lustig, MD, and colleagues in the journal Nature, the sugar described as "toxic".
Robert Lustig and his colleagues argue that sugar is "toxic", since it involves a "deadly effect" through the molecule of fructose from sucrose, but this in its arguments speak excess consumption of sugars and generally as such.
In the United States is encouraged consumption of fruits and vegetables, and consumption of products from these, knowing that fruits are the third source of fructose in the American diet.
Our studies and meta-analyzes indicate controlled feeding use of fructose are beneficial for metabolism or no side effects for weightloss.
Publication of Lustig was called as "correspondence" in the February 23 edition of the journal Nature in which they appear comments from other scientists. Some of these comments made called the "document review" Lustig and colleagues as "extreme", "ridiculous" and "sensational". They also noted that the document contained simplifications seeking to demonize sugar instead of addressing the complex factors (such as overeating and add sedentary lifestyle) that closely associated with obesity in a way that serves public health.
Some clinical nutritionists as Christiani Jeyakumar Henry, Ph.D., and Viren Ranawana, Ph.D., Institute of Singapore, described that "the contribution of sugar to chronic diseases is higher for developed countries that sends development "and it is more likely that excessive consumption of carbohydrates high glycemic index are the main cause of obesity and diabetes.
Fructose, unlike other sugars, glucose is low because it is metabolized differently.
The most common mistake that some people comment is calling fructose = glucose, since the former has a better metabolize glucose and other sugars. Glucose and other sugars that are metabolized differently way fructose.
Fructose does not stimulate insulin and is characteristically low glycemic index. For these reasons, it is often used in different applications of low glycemic index foods ( mostly similar to what is in the fruit amounts). Its stability and better perceived sweetness compared to other sugars, making it more favorable, leading to less use of sugar in general.
