The Human Brain Reacts Differently To The Use Of Fructose And Glucose

The Human Brain Reacts Differently To The Use Of Fructose And Glucose.
New check out suggests that fructose, a inferior sugar found result in fruit and added to many other foods as part of high-fructose corn syrup, does not dampen appetite and may cause kinsfolk to eat more compared to another simple sugar, glucose. Glucose and fructose are both simple sugars that are included in correspondent parts in table sugar. In the new study, brain scans suggest that many things happen in your brain, depending on which sugar you consume.

Yale University researchers looked for appetite-related changes in blood circulate in the hypothalamic region of the brains of 20 healthy adults after they ate either glucose or fructose. When commoners consumed glucose, levels of hormones that play a role in theory full were high. In contrast, when participants consumed a fructose beverage, they showed smaller increases in hormones that are associated with nimiety (feeling full).

The findings are published in the Jan 2, 2013 debouchment of the Journal of the American Medical Association. Dr Jonathan Purnell, of Oregon Health & Science University in Portland, co-authored an opinion piece that accompanied the new study. He said that the findings replicate those found in late animal studies, but "this does not prove that fructose is the cause of the rotundity epidemic, only that it is a possible contributor along with many other environmental and genetic factors".

That said, fructose has found its way into Americans' diets in the sort of sugars - typically in the form of high-fructose corn syrup - that are added to beverages and processed foods. "This increased intake of added sugar containing fructose over the former times several decades has coincided with the take off in obesity in the population, and there is strong evidence from monster studies that this increased intake of fructose is playing a role in this phenomenon," said Purnell, who is allied professor in the university's division of endocrinology, diabetes and clinical nutrition.

But he stressed that nutritionists do not "recommend avoiding habitual sources of fructose, such as fruit, or the occasional use of honey or syrup". And according to Purnell, "excess consumption of processed sugar can be minimized by preparing meals at domicile using whole foods and high-fiber grains".

Connie Diekman, president of university nutrition at Washington University in St Louis, agreed that more dig into is needed. "This study provides an interesting look at how the brain reacts to abundant chemicals found in foods, but how this might impact obesity and the growing number of people who are obese cannot be definite from this study alone".

Dr Scott Kahan, director of the National Center for Weight and Wellness in Washington, DC, added there is a lot that scientists do not advised of about fructose and how it affects your body. "There are certainly differences between sugar molecules, and these are still being worked out scientifically".

According to Kahan, high-fructose corn syrup, a ubiquitous sweetener that manufacturers be attracted to because it is inexpensive, super-sweet and helps spread shelf life, gets a vitiated rap about its potential role in the obesity epidemic, but it has about the same amount of fructose as table sugar (sucrose). "We don't altogether know if there is some uniquely unhealthy aspect of high-fructose corn syrup".

One dingus that is clear is that "almost all of us eat too much sugar, and if we can moderate that we will be healthier on a number of levels". Dr Louis Aronne, fail and director of the Comprehensive Weight Control Program at New York-Presbyterian Hospital/Weill Cornell Medical Center in New York City, notorious that most sweeteners carry a mixture of glucose and fructose. For these reasons, "the effect is not as dramatic as you might see in a effort like this".

Still, a growing body of evidence is pointing toward the hypothalamic brain region as having a post in obesity. "Things as subtle as a change in sweetener can have an impact on how full somebody feels, and could example to an increase in calorie intake and an increasing pattern in obesity seen in this country".

So what to do? As a nutritionist, Sharon Zarabi, of Lenox Hill Hospital in New York City, tells her patients to skim chow labels anti aging. "Avoid having fructose or glucose listed as one of as the first three ingredients, and turn into sure that sugar is less than 10 grams per serving".
