More evidence that too much TV, computer time could harm your heart

Heart Health
Spending hours in front of a TV or computer monitor -- known as "screen time" -- has been linked to signs that the heart needs longer to recover from exercise, an indication of poor heart health. In fact, in recent blogs I've told you of other studies showing  that "Screen time (TV and computer) may be linked to increased heart risks," and "Taking small breaks from sitting may help heart and metabolic health." Now comes another study, this one published in the journal Heart Asia, which included more than 2,000 people – all in their 30s and from the United States – who didn't have heart disease.

However, no fully relevant data have been presented to account for a direct link between dietary fructose intake and health risk markers such as obesity, triglyceride accumulation, and insulin resistance in humans. Here's what we do know: First: a re-evaluation of published epidemiological studies concerning the consumption of dietary fructose or mainly high fructose corn syrup shows that most of such studies have been cross-sectional or based…

Joint Health
I often have patients ask if they can do their physical rehabilitation at home – either because it's too far to drive to physical therapy or too expensive. Some want home physical therapy with a therapist, some want to try to do it themselves. We've not really known if it would be effective for folks to "do it yourself" or not. Now we may have an answer. The Los Angeles Times' "Booster Shots" blog reported that Internet-based rehabilitation for patients who had knee replacement surgery proved as effective as traditional therapy sessions, according to a study in the Journal of Bone and Joint Surgery. Researchers "compared a live, Internet-based rehabilitation program to a traditional one for 65 men and women who had recent knee replacement surgery" and found that "after…
