Are bacteria making you hungry? (12/28/2012)

Over the last half decade, it has become increasingly clear that the normal gastrointestinal (GI) bacteria play a variety of very important roles in the biology of human and animals. Now Vic Norris of the University of Rouen, France, and coauthors propose yet another role for GI bacteria: that they exert some control over their hosts' appetites. Their review was published online ahead of print in the Journal of Bacteriology. ...> Full Article


A new, super-nutritious puffed rice for breakfast cereals and snacks (12/26/2012)

A new process for blowing up grains of rice produces a super-nutritious form of puffed rice, with three times more protein and a rich endowment of other nutrients that make it ideal for breakfast cereals, snack foods and nutrient bars for school lunch programs, scientists are reporting. Their study appears in ACS' Journal of Agricultural and Food Chemistry. ...> Full Article


Curbing car travel could be as effective as cutting calories (12/24/2012)

Those considering how to maintain a healthy weight during holiday festivities, or looking ahead to New Year's resolutions, may want to think twice before reaching for traditional staples like cookies or candy - or the car keys. A new study by University of Illinois researchers suggests that both daily automobile travel and calories consumed are related to body weight, and reducing either one, even by a small amount, correlates with a reduction in body mass index. ...> Full Article


Use 'em, don't lose 'em! Eating egg yolks adds nutritious benefits (12/16/2012)

Decades of mixed messaging regarding dietary cholesterol have led to avoidance of certain foods, such as eggs, particularly among individuals who are faced with health conditions. However, a recent study published in Metabolism suggests that including whole eggs as part of a weight loss diet may have positive effects on lipoprotein profiles for individuals with metabolic syndrome. ...> Full Article


HPV in older women may be due to reactivation of virus, not new infection (12/15/2012)

A new study suggests that human papillomavirus (HPV) infection in women at or after menopause may represent an infection acquired years ago, and that HPV infections may exist below limits of detection after one to two years, similar to other viruses, such as varicella zoster, which can cause shingles. The study highlights the need for additional research to better understand HPV infections and the role of HPV persistence and reactivation, particularly in women of the baby boomer generation. ...> Full Article


Battling brittle bones... with broccoli and spinach? (12/14/2012)

Battling brittle bones... with broccoli and spinach?A new study from engineering researchers at Rensselaer Polytechnic Institute shows, for the first time, how the little-understood protein osteocalcin plays a significant role in the strength of our bones. The findings could lead to new strategies and therapeutics for fighting osteoporosis and lowering the risk of bone fracture. ...> Full Article


To make old skin cells act young again, boost their surroundings, scientists show (12/12/2012)

As we get older, the trillions of cells in our body do too. And like us, they become less resilient and able to weather the stress of everyday life. Our skin especially tells the tale of what's happening throughout our bodies. But recently, scientists have learned that aging cells bear only part of the blame for this downward spiral. ...> Full Article


At high altitude, carbs are the fuel of choice (12/10/2012)

At high altitude, carbs are the fuel of choiceMice living in the high-altitude, oxygen-starved environment of the Andean mountains survive those harsh conditions by fueling their muscles with carbohydrates. The findings, reported online on Dec. 6 in Current Biology, a Cell Press publication, provide the first compelling evidence of a clear difference in energy metabolism between high- and low-altitude native mammals. ...> Full Article


Could high insulin make you fat? Mouse study says yes (12/9/2012)

Could high insulin make you fat? Mouse study says yesWhen we eat too much, obesity may develop as a result of chronically high insulin levels, not the other way around. That's according to new evidence in mice reported in the Dec. 5th Cell Metabolism, a Cell Press publication, which challenges the widespread view that rising insulin is a secondary consequence of obesity and insulin resistance. ...> Full Article


Men with erection problems are 3 times more likely to have inflamed gums (12/8/2012)

Men in their thirties who had inflamed gums caused by severe periodontal disease were three times more likely to suffer from erection problems, according to a study published in the Journal of Sexual Medicine. ...> Full Article


Listen up, doc: Empathy raises patients' pain tolerance (12/7/2012)

Listen up, doc: Empathy raises patients' pain toleranceA doctor-patient relationship built on trust and empathy doesn't just put patients at ease -- it actually changes the brain's response to stress and increases pain tolerance, according to new findings from a Michigan State University research team. ...> Full Article


Analysis of conflicting fish oil studies finds that omega-3 fatty acids still matter (12/6/2012)

A new analysis helps to sort through conflicting findings from literally hundreds of studies on use of omega-3 fatty acids for heart disease. It concludes that they still matter; they do work; and that modern therapies for cardiovascular disease help to mask the benefits omega-3 consumption might otherwise provide. ...> Full Article


People not hooked on fish could get omega-3 through fortified milk (12/5/2012)

Food science researchers at Virginia Tech may have reeled milk into the fish oil delivery system, showing it is possible to incorporate omega-3 fatty acids into milk and dairy-based beverages in amounts sufficient to promote heart health, without destroying the milk's taste. The innovation may be a way to help people who do not eat fish get some of the heart-healthy benefits of fish oil. ...> Full Article


Vitamin D tied to women's cognitive performance (12/4/2012)

New review associates vitamin D with lower rates of tooth decay (12/1/2012)

New review associates vitamin D with lower rates of tooth decayHealth scientists have long disputed the role of vitamin D in preventing tooth decay. A new review of existing studies suggests that vitamin D may indeed have a role in tooth health. The review encompassed 24 controlled clinical trials from the 1920s to the 1980s. About 3,000 children in several countries participated. Vitamin D levels in many populations are declining while dental caries in children are increasing. The findings reaffirm the importance of vitamin D for dental health. ...> Full Article
