In 1972, a British scientist sounded the alarm that sugar – and not fat – was the greatest danger to our health. But his findings were ridiculed and his reputation ruined. How did the world’s top nutrition scientists get it so wrong for so long?
Foods with high glycemic index are linked to lung cancer, scientists found
Such foods include white bread, bagels, corn flakes and puffed rice
Study found a 49% higher risk of lung cancer in people with high GI diets Scientists recommends people cut high GI foods out of their diet

Science Daily — Juice boxes look harmless enough, with those kid-size, bendable straws and promises of 100 percent vitamin C.
As healthy as juice seems, parents need to be wary of doling out too much to children, especially during the summer when kids need plenty of fluids to stay safe, a University of Florida expert says. Unlike water and low-fat milk, fruit juices and sodas are laden with fructose, a type of naturally occurring sugar that could trigger obesity in humans.
As healthy as juice seems, parents need to be wary of doling out too much to children, especially during the summer when kids need plenty of fluids to stay safe, a University of Florida expert says. Unlike water and low-fat milk, fruit juices and sodas are laden with fructose, a type of naturally occurring sugar that could trigger obesity in humans, said Richard Johnson, MD., the J. Robert Cade professor of nephrology in the UF College of Medicine.
“Studies in humans have linked drinking excessive amounts of fruit juice and soft drinks with an increased risk for not only obesity, but also diabetes and high blood pressure,” said Johnson, also the college’s chief of nephrology, hypertension and renal transplantation. “In terms of obesity, fructose actually may set you up to not turn off your satiety response, so you will continue to eat.”
Unlike glucose, fructose does not signal the body to produce insulin, the hormone that turns sugar into energy and lets the brain know it’s time to stop eating. Fructose actually seems to do the opposite — causing resistance to insulin and blocking the “do not eat” order from making it to the brain, Johnson said.
Because fructose doesn’t stimulate insulin, consuming too much over a long period of time could trigger weight gain, said Peter Havel, Ph.D., a research endocrinologist at the University of California at Davis who studies fructose.
“If you consume fructose, it’s more like you’re consuming fat,” Havel said.

http://tiny.iavian.net/9x1l Living closer to nature is better for your health, new research suggests — and may even extend your life.
A study just published in the journal Environmental Health Perspectives found that people who live in “greener” areas, with more vegetation around, have a lower risk of mortality. The health benefits are likely thanks to factors such as improved mental health, social engagement and physical activity that come with living near green spaces.
"Reminder: Facebook can take down your 4.4 million-like page anytime it wants without explanation," Nieman Lab's Joshua Benton tweeted on Monday.
Benton's colleague, Laura Hazard Owen, suggested that "the takedown of such a large and popular page could add fuel to concerns that publishers are giving Facebook too much power."

Lizzy Kelly, a history student at Sheffield added: “Students might be more inclined to read what academics want them to if our curricula weren’t overwhelmingly white, male and indicative of a society and structures we fundamentally disagree with because they don't work for us.”

Excess Glucose May Harden Heart and Lungs
Research found that glucose suppressed ferroelectricity up to 50%....
New research conducted at the University of Washington and Boston University has shown that excess glucose in the body could damage the elastic proteins found in important organs such as the heart and lungs, which aid in breathing and pumping blood.
In this study, aortic tissue was separated into two types of proteins, elastin and collagen. Ferroelectric switching is what allows the elastin to be flexible and convey repeated pulses, in organs such as the arteries. It is a response to an electric field in which a molecule switches from having a positive charge to a negative charge. Recent discoveries in animal tissue have traced this property to elastin in animal tissues.
When researchers treated the elastin with sugar, they noticed a 50% suppression of the ferroelectric switching. The sugar-protein interaction mimics glycation, a process where sugar molecules attach to proteins and degrade their structure and function. Consequently, hardening of the tissues, and degradation of ligaments and arteries has been observed, leading to an overall loss of function.
Co-author, Jiangyu Li, says, "This could be associated with aging and diabetes."

The Inter-Relationships between Vegetarianism and Eating Disorders among Females
Accepted 24 April 2012.
When individuals with a suspected or diagnosed eating disorder adopt a vegetarian diet, health care professionals might worry that this choice could function as a socially acceptable way to legitimize food avoidance. Yet only limited research has examined vegetarianism in relation to eating disorders. Our study objectives were to compare individuals with and without an eating disorder history and individuals at different stages of eating disorder recovery on past and current vegetarianism and motivations for and age at becoming vegetarian.
The three recovery status groups (fully recovered, partially recovered, and active eating disorder) did not differ significantly in percentiles endorsing a history of vegetarianism or weight-related reasons as primary, but they differed significantly in current vegetarianism (33% of active cases, 13% of partially recovered, 5% of fully recovered; P<0.05). Most perceived that their vegetarianism was related to their eating disorder (68%) and emerged after its onset. Results shed light on the vegetarianism-eating disorders relation and suggest intervention considerations for clinicians (eg, investigating motives for vegetarianism).
