Benefits of eating egg

Benefits of eating egg
The Nutrition Today review analyzes more than 25 protein studies and concludes that the all-natural, high-quality protein in eggs contributes to strength, power and energy in the following ways:
  • Sustained energy: The protein in eggs provides steady and sustained energy because it does not cause a surge in blood sugar or insulin levels, which can lead to a rebound effect or energy "crash" as levels drop. Eggs are a nutrient-rich source of high-quality protein and provide several B vitamins mandatory for the production of energy in the body, such as thiamin, riboflavin, folate, B12 and B6.
  • Muscle strength: Dietary protein intake directly influences muscle mass, strength and function in people of all ages. One egg provides more than six grams of high-quality protein (13 percent of the Daily Value), which can help individuals build and preserve muscle mass, and help elderly adults prevent muscle loss. Eggs are also rich in leucine, an essential amino acid that contributes to the muscle's ability to use energy and aids in post-exercise muscle recovery.
  • Gold-standard protein: The high-quality protein in eggs provides all of the essential amino acids our bodies need to build and maintain muscle mass. In fact, the quality of egg protein is so high that researchers frequently use eggs as the standard for evaluating the protein quality of other foods.(5).........

Regular exercise to prevent colon cancer

Regular exercise to prevent colon cancer
An ambitious newly released study has added considerable weight to the claim that exercise can lower the risk for colon cancer. Scientists at Washington University School of Medicine in St. Louis and Harvard University combined and analyzed several decades worth of data from past studies on how exercise affects colon cancer risk. They observed that people who exercised the most were 24 percent less likely to develop the disease than those who exercised the least.

"What's really compelling is that we see the association between exercise and lower colon cancer risk regardless of how physical activity was measured in the studies," says lead study author Kathleen Y. Wolin, Sc.D., a cancer prevention and control expert with the Siteman Cancer Center at Barnes-Jewish Hospital and Washington University. "That indicates that this is a robust association and gives all the more evidence that physical activity is truly protective against colon cancer".

Colorectal cancer is the third most common type of cancer. Each year more than 100,000 people in the United States are diagnosed with colon cancer and about 40,000 are diagnosed with rectal cancer. The study suggests that if the American population became significantly more physically active, up to 24 percent, or more than 24,000, fewer cases of colon cancer would occur each year.........

Benefits of exercise on quitting smoking

Benefits of exercise on quitting smoking
Research from the University of Exeter reveals for the first time, that changes in brain activity, triggered by physical exercise, may help reduce cigarette cravings. Reported in the journal Psychopharmacology, the study shows how exercise changes the way the brain processes information among smokers, thereby reducing their cravings for nicotine. For the first time, scientists used functional Magnetic Resonance Imaging (fMRI) to investigate how the brain processes images of cigarettes after exercise.

The study adds weight to a growing body of evidence that exercise can help manage addiction to nicotine and other substances. It backs up prior studies, which have shown that just one short burst of moderate exercise can significantly reduce smokers' nicotine cravings.

Ten regular smokers were asked to cycle at a moderate pace for ten minutes, after 15 hours of abstinence from nicotine. They were then given an fMRI scan while they viewed a series of 60 images. Some visuals featured cigarettes and would normally induce cravings in a smoker. On a second occasion, the same group was given an fMRI scan and shown the same series of images without having undertaken exercise. They were also asked to report on their cravings for nicotine during both phases of the study.........

Parent's role in teen obesity

Parent's role in teen obesity
There appears to be a reason teenagers eat more burgers and fries than fruits and vegetables: their parents.

In a new policy brief released recently by the UCLA Center for Health Policy Research, scientists observed that adolescents are more likely to eat at least five servings of fruits and vegetables a day if their parents do. Contrarily, teens whose parents eat fast food or drink soda are more likely to do the same.

Every day, more than 2 million California adolescents (62 percent) drink soda and 1.4 million (43 percent) eat fast food, but only 38 percent eat five or more servings of fruits and vegetables, as per the policy brief, "Teen Dietary Habits Correlation to Those of Parents."

The cause of the deficit of healthy foods in teen diets has been attributed in part to the high concentration of fast food restaurants in certain cities and neighborhoods and other environmental factors.

The new research is a reminder, however, that "good dietary habits start at home," as per center research scientist Susan H. Babey, a co-author of the policy brief. "If parents are eating poorly, chances are their kids are too." .

Nearly one-third (30 percent) of California's teenagers are overweight or obese. Poor dietary habits, along with environmental and other factors, are strongly associated with obesity.........

Those inactive and overweight preschool children

Those inactive and overweight preschool children
The rate of childhood obesity has risen significantly in the United States, with a number of children becoming overweight at younger ages. At the same time, the number of preschoolers in center-based programs is also on the rise. Now a newly released study finds that, contrary to conventional wisdom, preschoolers don't move around a lot, even when they're playing outside.

The study, by an interdisciplinary team of scientists at the University of South Carolina (USC), Michigan State University, and East Carolina University and led by Professor Russell R. Pate (at USC), is reported in the January/February 2009 issue of the journal Child Development

Using information from the Children's Activity and Movement in Preschools Study (CHAMPS), a project funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), the scientists looked at 3-, 4-, and 5-year olds enrolled in 24 community-based preschool programs.

They observed that the preschoolers were inactive for much of their preschool day, with 89 percent of physical activity characterized as sedentary. Even when they played outside, a time when children are expected to move around, 56 percent of their activities were sedentary.

Furthermore, teachers very rarely encouraged the children to be physically active. But when balls and other items were made available, particularly outside, and when they had open spaces in which to play, the children were more likely to be active.........

Sleep apnea may be cured if you put effort to lose weight

Sleep apnea may be cured if you put effort to lose weight
For sufferers of obstructive sleep apnea (OSA), a newly released study shows that losing weight is perhaps the single most effective way to reduce OSA symptoms and associated disorders, as per a newly released study in the American Journal of Respiratory and Critical Care Medicine, one of the American Thoracic Society's three peer-evaluated journals.

Weight loss may not be a new miracle pill or a fancy high-tech therapy, but it is an exciting treatment for sufferers of OSA both because of its short- and long-term effectiveness and for its relatively modest price tag. Surgery doesn't last, continuous positive airway pressure (CPAP) machines are only as effective as the patient's adherence, and most other devices have had disappointing outcomes, in addition to being expensive, unwieldy and having poor patient compliance. Furthermore, OSA is generally only treated when it has progressed to a moderate to severe state.

"Very low calorie diet (VLCD) combined with active lifestyle counseling resulting in marked weight reduction is a feasible and effective therapy for the majority of patients with mild OSA, and the achieved beneficial outcomes are maintained at 1-year follow-up," wrote Henri P.I. Tuomilehto, M.D., Ph.D., of the department of Otorhinolaryngology at the Kuopio University Hospital in Finland.........

Protein that may explain 'healthy' obesity

Protein that may explain 'healthy' obesity
Dr. Philipp Scherer
Mice whose fat cells were allowed to grow larger than fat cells in normal mice developed "healthy" obesity when fed a high-fat diet, scientists at.

UT Southwestern Medical Center found in a newly released study.

The fat but healthy mice lacked a protein called collagen VI, which normally surrounds fat cells and limits how large they can grow, like a cage around a water balloon. The findings appear online and in a future edition of Molecular and Cellular Biology.

"The mice lacking collagen VI fared much better metabolically than their counterparts that retained this particular collagen," said Dr. Philipp Scherer, director of the Touchstone Center for Diabetes Research at.

UT Southwestern and the study's senior author. "The mice without collagen VI don't develop inflammation or insulin resistance. They still get obese, but it's a 'healthy' obesity".

When people take in more calories than needed, excess calories are stored in adipose or fatty tissue. The fat cells are embedded in and secrete substances into an extracellular matrix, a type of connective tissue that provides support to fat tissue, like scaffolding. Collagen VI is one component of the extracellular matrix. Too much of this connective tissue prevents individual cells from expanding and can lead to fibrosis and eventually inflammation.........

Weight loss reduces urinary incontinence

Weight loss reduces urinary incontinence
Reducing urinary incontinence can now be added to the extensive list of health benefits of weight loss, as per a clinical trial funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the Office of Research on Women's Health (ORWH), both part of the National Institutes of Health (NIH). The paper reporting the results of the trial would be reported in the January 29 issue of the New England Journal (NEJM)

The Program to Reduce Incontinence by Diet and Exercise (PRIDE), conducted in Birmingham, Alabama, and Providence, Rhode Island, recruited a total of 338 obese and overweight women who leaked urine at least 10 times per week. The women were randomly assigned to either an intensive six-month weight-loss program of diet, exercise and behavior modification or to a group that received information about diet and exercise, but no training to help them change habits.

The researchers report that women in the intensive weight-loss group lost an average 8 percent of their body weight (about 17 pounds) and reduced weekly urinary incontinence episodes by nearly one-half (47 percent). In contrast, women in the information-only group lost an average 1.6 percent of body weight (about 3 pounds) and had 28 percent fewer episodes.

"Clearly, weight loss can have a significant, positive impact on urinary incontinence, a finding that may help motivate weight loss, which has additional health benefits such as preventing type 2 diabetes," said NIDDK Director Griffin P. Rodgers, M.D.........

Regular sprint boosts metabolism

Regular sprint boosts metabolism
A regular high-intensity, three-minute workout has a significant effect on the body's ability to process sugars. Research reported in the open access journal BMC Endocrine Disorders shows that a brief but intense exercise session every couple of days appears to be the best way to cut the risk of diabetes.

Professor James Timmons worked with a team of scientists from Heriot-Watt University Edinburgh, Scotland, to investigate the effect of 'high-intensity interval training' (HIT) on the metabolic prowess of sixteen sedentary male volunteers. He said, "The risk of developing cardiovascular disease and type two diabetes is substantially reduced through regular physical activity. Unfortunately, a number of people feel they simply don't have the time to follow current exercise guidelines. What we have found is that doing a few intense muscle exercises, each lasting only about 30 seconds, dramatically improves your metabolism in just two weeks."

Current exercise guidelines suggest that people should perform moderate to vigorous aerobic and resistance exercise for several hours per week. While these guidelines are very worthwhile in principle, Timmons suggests that a lack of compliance indicates the need for an alternative, "Current guidelines, with regards to designing exercise regimes to yield the best health outcomes, may not be optimal and certainly require further discussion. The low volume, high intensity training utilized in our study substantially improved both insulin action and glucose clearance in otherwise sedentary young males and this indicates that we do still not fully appreciate the traditional correlation between exercise and diabetes".........

Our microbes, ourselves

Our microbes, ourselves
The team's study is the first molecular survey of gut microbial diversity following surgical weight loss (gastric bypass), and has helped solidify the link between methane producing microbes and obesity. This means the drastic anatomical changes created by gastric bypass surgery appear to have profound effects on the microorganisms that inhabit the intestine. This change may be part of the reason that gastric-bypass surgery is the most effective means to treat obesity today.

Credit: Mayo Clinic

In terms of diversity and sheer numbers, the microbes occupying the human gut easily dwarf the billions of people inhabiting the Earth. Numbering in the tens of trillions and representing a number of thousands of distinct genetic families, this microbiome, as it's called, helps the body perform a variety of regulatory and digestive functions, a number of still poorly understood.

How this microbial mlange appears to be associated with body weight changes linked to morbid obesity is a relevant and important clinical question that has received recent attention. Now, a newly released study suggests that the composition of microbes within the gut may hold a key to one cause of obesityand the prospect of future therapy.

In the January 19 early online edition of the Proceedings of the National Academy of Science, scientists at Arizona State University's Biodesign Institute in collaboration with colleagues at the Mayo Clinic, Arizona, and the University of Arizona, reveal a tantalizing link between differing microbial populations in the human gut and body weight among three distinct groups: normal weight individuals, those who have undergone gastric bypass surgery, and patients suffering the condition of morbid obesitya serious, often life-threatening condition linked to diabetes, cardiovascular disease, cancer and psychosocial disorders. Obesity affects around 4 million Americans and, each year, some 300,000 die from obesity-related illness.........

Did you know?
Exercise can't stop the aging process, but experts at Baylor College of Medicine in Houston say that for the elderly, whether it's weight training, walking, swimming or biking, 30 minutes of exercise three to five times a week is a good prescription for aging."It's never too late to start exercising," said Dr. Robert Roush, an associate professor of medicine-geriatrics at BCM. "Being physically active and exercising regularly can help prevent or delay some diseases and disabilities as people age.".
