How-TV is Worse than PC and Green Tea May Lower Bad Cholesterol

After weight Loss now green tea has another benefit - Lowering Bad Cholesterol

A new analysis of published studies finds that consuming green tea, either as a beverage or in capsule form, is linked to significant but modest reductions in total and LDL or "bad" cholesterol, but the researchers found no link with HDL or "good" cholesterol and triglycerides. Dr Olivia J. Phung, of the College of Pharmacy at Western University of Health Sciences in Pomona, California, and colleagues, write about their findings in the November issue of the Journal of the American Dietetic Association.

Green tea contains catechins, polyphenolic compounds that are known to exert numerous protective effects, particularly on the cardiovascular system.

However, Phung and colleagues note that although randomized controlled trials have examined the effect of green tea catechins on blood fats or lipids, including cholesterol, these have been small and shown conflicting results. So they decided to pool and analyze the evidence so far from all the studies they could find that examined the relationship between consumption of green tea catechins and changes in levels of total, low-density lipoprotein (LDL), high-density lipoprotein (HDL) cholesterol, and triglycerides.

They searched all the recognized databases up to March 2010 and found 20 randomized controlled trials, covering a total of 1,415 participants, that reported changes in at least one of these levels.When they pooled and analyzed the data from these trials, they found that:

Green tea catechins, at doses ranging from 145 to 3,000 mg per day (including consumption as green tea beverage and extract in capsules) taken for 3 to 24 weeks, led to statistically significant reductions in total and LDL ("bad") cholesterol compared to controls who did not consume any.

Green tea catechins did not alter HDL ("good") cholesterol or triglyceride levels. The results showed that the beverage form of green tea was more consistently effective than capsules, though the overall benefits were quite small, Phung told Reuters news agency in an email where she urged patients already taking cholesterol-lowering medication not to switch to green tea, either as capsules or as a beverage.

TV is Worse than PC for heart Disease

I think parents need to allow their child to watch T.V. for a certain period of thime which will eliminate this risk. I feel like its more to do than just watch a T.V. For example, one can read, write, and do homework rather than watching T.V. all day but it’s up to the parent to tell them the dos and dont’s which will benefit them later on in life.

Physical activity will definitely lower children’s chances of developing cardiovascular disease down the road, but physical inactivity will not necessarily increase it. Findings from a recent Queen’s University study shows different kinds of sedentary behaviour may have different consequences for young people’s health.

“Even if a child is physically active, this activity is really only making up a short period of their whole day, so it’s important to look at other aspects of their day to see what’s going on. Part of that is the kind of sedentary behaviours they engage in,” says Valerie Carson, a doctoral candidate in the School of Kinesiology and Health Studies at Queen’s.Previous research has identified high volumes of sedentary behaviour as a risk factor for cardiovascular diseases in adults. But among the children she surveyed, Ms. Carson found no general connection between the volume of sedentary behaviour and the risk of developing diabetes or coronary heart disease.

Instead, she noticed some types of sedentary activities having a greater impact on children’s health than others. Specifically, high levels of TV viewing predicted higher cardio-metabolic risk, whereas high computer use did not.One possible explanation is that TV viewing falls near the bottom on the scale of energy expenditure, according to some research. Another is that activities like snacking between meals that usually go hand-in-hand with specific kinds of screen times may be causing the associated health risks.

“The take home message is that we want children to be more physically active, but then, at the same time, we need to think about what they’re doing the rest of the time,” explains Mr. Carson. “Our study suggests we should also limit children’s television viewing time.”

Ms. Carson collaborated on this study with Dr. Ian Janssen (Department of Community Health and Epidemiology). Their work was supported by the Canadian Institutes of Health Research (CIHR).The findings were recently published in the journal BMC Public Health. (BMC Public Health.)
