For Teens, Too Much Sugar Can Be A Heartbreaker : Shots - Health News Blog : NPR

Teenagers who guzzle a daily bottle of soda are probably not thinking much about their hearts as the sweet stuff runs down their throats.

Antonio Garcia re-stocks the beverages at The Corner Market in Washington, D.C., in 2010. Study author Jean Welsh says that sweetened beverages tend to be the biggest source of added sugar.

But a new study suggests they should be. Teens who consume lots of added sugar — usually found in sugar-sweetened beverages — risk heart problems later in life, researchers found.

This main problem is the sheer volume of sugar American teens consume: 28.3 teaspoons of added sugar a day on average. That makes up a whopping one-fifth of their daily calories, according to Jean Welsh, study author and post-doctoral fellow in pediatric nutrition at Emory University School of Medicine. It works out to an average of 476 calories a day.

 

Teens who consumed the highest percentage of their calories from added sugar had less of the "good" cholesterol compared with consumers who ate the least sugar. Another finding was that teens who consumed more added sugars also had higher levels of the "bad" cholesterol  and fats called triglycerides.

OrganizedWisdom Finds Free Experts Make for SEO Success - NYTimes.com

With Demand Media currently planning a high-profile IPO and issues being raised about the impact of “content farms” on search results, there is a lot of attention being paid to the question of content aggregation and its effect on the web. OrganizedWisdom Health, a health-resource service, now believes it’s better — and more profitable — to organize free content rather than pay for low-wage material.

The New York-based startup has spent most of the past four years building up an index of “wisdom cards:” topical health entries that were written by contributors for a small fee. At any given moment, OrganizedWisdom contracted with 100 writers, who covered a wide array of medical topics. But exactly one year ago, the company dropped the paid-content route and embraced a free expert model. So where does the content come from? The startup keeps track of some 5,000 doctors and health experts who use social media, and collects their contributions into wisdom cards.

Phys Ed: If You Are Fit, You Can Take It Easy - NYTimes.com

New Year’s resolutions tend to war with wintertime malaise. Resolution urges you to work out. Malaise suggests that you linger in bed. But there’s good news for those of us torn between these impulses. A number of newly published studies offer compelling reasons to get out and exercise on the one hand, as well as new estimates of just how little we can do and still benefit on the other.

The most sobering of the recent studies, published last month in The British Journal of Sports Medicine, looked at a large group of retired elite male athletes, most now in their 50s. Some had remained physically active, although they were no longer competing. Others had taken fully to sloth, avoiding almost all exercise. When the researchers examined the health profiles of the two groups, they found, to no one’s surprise, that the sedentary ex-athletes had a much higher risk of metabolic abnormalities, including insulin resistance, than their more active counterparts. Training hard and often in their youth had not conferred lifelong health benefits on the athletes as they aged, not if they now sat around all day.

Similarly, although in a more compressed time frame, a study published earlier this year found that when a group of world-class kayakers completely quit training (at the end of a competitive season), they rapidly lost strength and endurance. After only five weeks of not training, according to one measure of strength, they’d sloughed off about 9 percent of their muscular power and 11 percent of their aerobic capacity.

Is Santa sick? A doctor gives St. Nick a checkup - Health - Healthy Holidays - msnbc.com

He is overweight, constantly flushed, trying to accomplish a superhuman feat – and may be using cookies to deal with the stress.

Should we be worried about Santa's health? [ Santa Claus: The Real Man Behind the Myth ]

In advance of his epic journey on Christmas Eve, we asked a doctor to give him a checkup.

Red nose and cheeks
While some may attribute a ruddy appearance to fever or worse (too much mulled wine?), Dr. Rachel Vreeman of the Indiana University School of Medicine thinks Santa's rosy complexion is likely benign.
