Blogger Martha Edwards wrote about it on June 4 -- the fact that cancer cases are soon to explode in Asia, despite the obvious health benefits of Asian-based diets.

It's not the Asian diet influencing rising cancer rates, though. It's the bad Western habits Asians are adopting that will inevitably lead these folks down a dangerous road.

Smoking, drinking, and consumption of unhealthy foods -- all contributors to various cancers -- will drive Asian cancer rates up by 60 percent by the year 2020. Larger aging populations and lack of prevention and treatment in developing countries will also drive this trend.

You've surely known kids whose parents smoke declare their repulsion for the habit. The health risk, the expense, the filth of smoking seem to deter many youngsters from following in the footsteps of mom and dad. Theoretically, anyway. In practice, these same kids may fall prey to the very act they vowed to reject.

How about kids raised in households filled with sugary snacks and drinks, foods packed with fat, salt, and calories, and parents with expanding waistlines? Seems only natural these children, despite good intentions, end up struggling with healthful eating and weight management.

We are what our parents teach us. It's all we know for a good many years. And by the time we are able to make our own independent decisions, it's often too late. Our parents' actions and values are already programmed within us -- and it takes hard work to switch things up.

So here's my plea for this Sunday morning: do your kids a favor and become a positive role model. Don 't just tell your little ones what is right and healthy and virtuous -- show them. Let your behavior be the gold standard now, so that later, it's likely to be what your sweet babies will fall back on.

Here are seven ways to get started:

Feed 'em well
If kids learn healthy eating habits early, they're likely to stick with them. Offer whole grains options (rice, bread, pasta) and snacks that are not in the junk food group. Don't even buy the stuff you may later wish to clear out of your cupboard. Guests at our house are offered two drink options -- water or milk. Why? Because if we have juice (it's loaded with sugar) or soda (also sugary and calorie-laden), our kids just can't hold back. But if we don't have these beverages, they are never an option. Out of sight, out of mind.

Keep 'em moving
Take your kids to the park, get them running around your backyard, take them swimming, organize a kid-friendly football game, invest in a kite. Quiet activities are also good -- and necessary -- but when in doubt about how to entertain your busy little bees, make them move!

Let 'em see you sweat
You need to keep moving too. Not only for your own well-being -- that's obvious -- but so your kids see your physical activity as a staple of healthy living. Teach your kids to do push-ups and sit-ups and do them together. Jump rope, run laps at a local track, ride bikes, or dance. Just don't expect your kids to stay active if your idea of exercise is flipping through TV channels.

No TV
Turn off that TV. Rid your household of junk-food commercials, mind-numbing content, and addictive inactivity. Let TV be a treat -- a small one -- and not an expectation.

No smoking
Need I explain? It's unhealthy, costly, dirty, and a sure contributor to cancer. Try with every ounce of your being to keep this habit away from your impressionable children.

No stress
Some stress is unavoidable. Some is even healthy. But the kind of stress that hurts our tummies, gives us headaches, and threatens our health should be minimized. We must do our best to control our own stress so its effects don't spill over. And we must teach our kids how to cope too. Fortunately, some of the techniques listed above also work for this category -- physical activity, for example, does wonders for lowering stress. We can become experts at deep breathing -- have your kids practice with you. And we can teach a bit of distraction. If homework is making kids crazy, go with them on a short walk where they can regroup and return to the task with a clear head.

No double standards
We simply cannot say one thing and do another. Smoking while preaching the dangers of the habit just doesn't make sense. Saying "no" to sweets with your hand in the cookie jar is downright unfair. Carrying around extra weight and demanding physical fitness is simply ineffective. So make a commitment to yourself and your kids that you will do as you say. It's the only way.

I just received my University of Florida alumni magazine and right smack in the middle of the publication is a story about cancer. The gist of the article is that there's an explosion of effort and activity in cancer research at this institution -- much like all over the nation -- and featured are all sorts of new cancer techniques and strategies and treatments. But one thing in particular stood out to me. What I read -- in the space of just two short sentences -- jumped off the page and really made me think.

This one thing is what I am about to share, and I'm calling it my Thought for the Day. It's a great morsel of information -- short, sweet, easy to digest, and perfectly powerful -- and so I invite you to read on, let this string of words sink into your mind, think about it over the course of the day, and then determine how you might use it in your own life. And then come back tomorrow, when another Thought for the Day will await you.

Think about this:

More than half of all cancer deaths can be prevented by maintaining a healthy lifestyle. Poor nutrition, obesity, physical inactivity, and cigarette smoking together account for 63 percent of all cancer deaths.

It seems like common sense to me -- that lifestyle choices can affect a person's risk for contracting cancer -- but apparently, many people are not aware of this. Or they are aware but are not heeding the advice that might just save them from this life-threatening disease. According to Carolyn "Bo" Aldige, president of the Cancer Research and Prevention Foundation, in Alexandria, Va., it's not undiscovered treatments and therapies that are key to fighting off cancer -- it's likely that the toll cancer takes can be reduced by lifestyle changes and routine screenings. Aldige reports that nearly half of all cancer deaths are preventable. And she urges us to consider these facts.

• Smoking is the most preventable cause of death in the United States and causes nearly one in five deaths, killing about 438,000 Americans each year. Yet 45 million adults still smoke -- 23 percent of them men and 19 percent of them women.
• Poor nutrition, inactivity, and obesity account for one in three of the 564,830 deaths from all cancers. Experts say that excess calories cause mutations that start genes traveling down pathways that cause cells to divide out of control -- and that's what cancer is. According to Aldige, if each person could magically acquire the perfect body mass index, there would be a whole lot less colorectal, breast, and prostate cancers.
• It requires little time and not much discomfort for certain screenings that can detect cancer at an early enough stage that it can be successfully treated. There are already screenings for breast cancer, colon cancer, prostate cancer, testicular cancer, cervical cancer, and skin cancer. And soon, there may be a simple screening for lung cancer too.
• A diet rich in nutrients and vitamin supplements helps maintain health and prevent cancer.

There are some highly effective defenses against cancer -- but they require some attention and effort on the part of each individual. Not everyone will make health-conscious choices -- some for reasons out of their control (lack of access to screenings, for example) and some for reasons I personally do not understand. But maybe that's because I have already had cancer and I know that I don't ever wish for it to return. So for that reason alone, I plan to adhere to the considerations listed above. It seems like common sense to me.

Want to lose weight and cut your cancer risks associated with weight gain? Get more sleep. Researchers found that women who slept for five hours per night were 32 percent more likely to experience major weight gain and 15 percent more likely to become obese compared with women who slept seven hours a night.

While researchers are certain about the results of the study, they cannot explain why women who get less sleep gain more weight. "Prior studies have shown that after just a few days of sleep restriction, the hormones that control appetite cause people to become hungrier, so we thought that women who slept less might eat more. But in fact they ate less," stated Sanjay Patel, M.D., Assistant Professor of Medicine at Case Western Reserve University. "That suggests that appetite and diet are not accounting for the weight gain in women who sleep less." They speculate it might be women who sleep less are more tired and somehow not moving as much during the day.

Two topics of conversation sure to make people uncomfortable are obesity and poverty. But both are necessary to conversation about cancer prevention because both increase the risk of cancer and death from cancer. Obesity is a cancer concern because being overweight is linked to an increase for some cancers. Obesity often reflects a nutrition-deficient fat-laden diet and a physically-inactive lifestyle that increase the risks for cancer. This is why the topic of obesity is so important to cancer prevention. Poverty often prevents people from seeking medical care because they cannot afford to see a doctor or undergo early cancer screening tests or cancer treatments once diagnosed with cancer. Researchers and organizations are beginning to devote more time and money into understanding the problem and in finding the solution to the rising obesity epidemic. No where is it more important than in the lives of our children.
