Upcoming presentation

Friday September 13th at 1:00 p.m. at the Temecula Learning Center.  Avoid the annoyances of aging. Growing older is inevitable but many of the physical and mental challenges that seniors face are not. More than twenty such topics that range from decreased energy to liver spots, irregular sleep to poor memory can be postponed or even avoided completely. Sponsored by Osher Lifelong Learning Center. To register see their web site at http://www.csusm.edu/el/olli or call 800-500-9377.

In the news

A recent study involving more than 23,000 people from Norway who were followed for two decades confirmed what we have been preaching for many years: folks who exercise live a lot longer than those who don’t. Couch potatoes had an overall death rate more than twice as high as exercisers and nearly THREE times the risk of dying from heart disease.

Two particularly interesting points came out of this study. First the amount of exercise: 2 and ½ hours of moderate exercise a week, that’s enough to break out a sweat, did the trick. Those who had really intense aerobic exercise (running, biking, swimming, etc.) for only an hour and a quarter a week saw the same good results. (Note – that’s what the statisticians found but such infrequent, intense exercise is not very practical and hard to maintain on a regular basis.)

A really interesting finding was that persons who were inactive but got religion and got the optimal amount of exercise on a regular basis got real results – a life expectancy increase between that of non-exercisers and moderate exercisers.

The take-home message? All exercise matters even if you are a late starter and it doesn’t take a long daily workout to become healthier

What this study didn’t address but others have – exercisers simply have more comfortable lives, with less shortness of breath, fatigue, loss of energy, arthritis, depression and stronger immune systems. What’s that worth?

Lifestyle

Your mother was right! Eating slowly is better for you but not for the reasons I heard when I was a kid: “Don’t eat so fast! You’ll choke on your food.” “It’ll make you sick.” Well, that second part was right but the sickness would take years, even decades to develop.

When we eat fast we eat more. That’s because it takes about 15 or 20 minutes for our hard-wired appetite-control mechanism to let us know that we’ve eaten enough. It was once thought that this was a simple mechanism brought into play by a hormone called cholecystokinin that was released when the stomach was full. We should have known! Nothing is really that simple in matters of biology. Scientists now know that there are several mechanisms, some regulated by hormone-like chemicals that control appetite.

Some of this came to light after lots of people had a portion of the stomach removed to lose weight. They didn’t get as hungry as they should have when portion sizes were limited to something about the size of a golf ball. The part of the stomach that had been removed contained cells that produced one of the hunger-causing hormones.

The bottom line: follow Mom’s advice and eat slowly. You’ll end up eating less, especially if your meals consist largely of fiber-rich vegetables.
