As time flies by, more and more progress is made in the fight against cancer. Over the years, new and better screening methods have emerged, cutting-edge technologies have surfaced, successful treatments have saved lives that may have otherwise been lost, and awareness has been raised about all sorts of cancer-related issues. It's amazing really, because in so many areas, we are not making progress.

According to research published in the March/April 2007 issue of WebMD: the Magazine, the per capita consumption of corn sweeteners in 2004 was 78.1 pounds in the United States -- up from 35.3 pounds in 1980. In 2005, the per capita consumption of candy by Americans was 25.7 pounds. We are pumping our bodies full of junk -- our rates of obesity in this country prove it.

When I think about our trend of over-eating and over-indulging, I gain a better appreciation of how far we've come medically. Not only have researchers, scientists, and medical experts made strides in the prevention and treatment of disease, they've done it against the odds. Just think how much more progress we'd make if we all did a little better at living healthy lives. Why not start now?

Scientists at Louisiana State University report that infection with a common virus may be a contributing factor to the increase in obesity rates across the United States and other countries.

The researchers shows that infection with human adenovirus-36 (Ad-36) changes adult stem cells obtained from fat tissue into fat cells. Stem cells not exposed to the virus were unchanged. The study also reported identification of a specific gene in the virus that appears to be involved in promoting this effect.

According to Magdelena Pasarica, M.D., Ph.D., "We're not saying that a virus is the only cause of obesity, but this study provides stronger evidence that some obesity cases may involve viral infections."

I promised two weeks ago when I wrote Sunday Seven: Seven ways to fine-tune your health that I'd be back to offer seven more grand ideas for optimizing your physical and emotional well-being. Here I am, with a mini-list of suggestions I gathered a while back from a newspaper article. If you don't already practice these strategies, then why not give them a try.

Eat breakfast

It's the most important meal of the day -- really. A breakfast high in complex carbohydrates and protein creates energy. Energy kick-starts metabolism and helps our bodies burn fat. We all know what fat does. It weighs us down and contributes to all kinds of health problems.

Get your sleep

Sleep restores our bodies. Sleep-deprived folks secrete more leptin, a protein hormone that increases appetite. Larger appetites increase food consumption. Increased food consumption spikes the risk of obesity. And so on. You know the drill.

A new government report on cancer addresses not only the tobacco industry, but also the food industry and the federal government. The report calls on the federal government to "cease being a purveyor of unhealthy foods."

According to the report, federal, state and local policies have made healthful food more expensive and less available while cutting back on physical education classes in schools.

The report recommends encouraging doctors and insurance companies to offer more programs regarding nutrition, smoking cessation and exercise. The report also urged Congress to authorize the FDA to regulate tobacco and to increase the cigarette tax. President Bush currently opposes such an increase in the cigarette tax.

Liver cancer experts attribute the rise in HCC, a highly aggressive cancer sometimes called hepatoma, to an increase decades ago in chronic infection with hepititis C & B and also chronic alcohol consumption. Worldwide liver cancer affects 700,000 people with 18,000 Americans diagnosed in 2006 and over 19,000 estimated to be diagnosed in 2007. The increase of this disease in the United States has doubled in one decade and over 16,000 people are estimated to die from the disease this year.

The rise in the United States is expected to increase. There are now 1.4 million people in the United States infected with HBV and 4 million are infected with HCV. Growing evidence suggests two other diseases now increasingly common in the United States to have significant risk factors for primary liver cancer. Diabetes and obesity.

HCC typically does not have any symptoms until its later stages which makes it difficult to diagnose. Traditional chemo does not treat the disease with much success and liver transplants or resection surgeries are needed. One reason why donors are very important in fighting this disease. When signs and symptoms do arise they might include weight loss, fatigue, pain in the upper right abdomen that may extend to the back and shoulder, feeling full after small meals, accumulation of fluid in the abdomen, nausea, loss of appetite, and jaundice.

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.

I was going to write a blog later in my series of blogs on toxins and stress and disease from the studies that I have been reading for the last month. But since a comment was made about stress and whether it has a correlation to disease to the previous blog I wrote on toxins and stress creating disease in our bodies, I will jump ahead and share some research I found on the relation of stress and disease. A relation to stress and disease has been researched by many doctors, psychologists, and medical research facilities and conclusions are that stress does several things to the body causing it to shut down in areas that can effect the body with disease and illness.

Do the common phrases, Tension Headache, Upset Stomach, Shaky Nerves, Tight Chest, ring a bell? Studies showed that work place stress has created an increase in heart disease and high blood pressure as well as making the body more susceptible to flu and viruses. It also has shown that stress can be related to Type 2 Diabetes as well as obesity. "Stress in general can disrupt the body's ability to process glucose, especially in people whose genetics make them vulnerable", said Richard Surwit of the Duke University Medical Center in a research article in the November/December issue of the journal Psychosomatic Medicine.

I wrote recently about the hidden amounts of sugar found in the foods we love so dearly. I learned all about this topic during my visit to Tucson's Canyon Ranch -- a world renowned health and healing destination -- and this sweet lesson came right as I'd decided to rid my diet of as much sugar as possible. Learning that one can of soda houses 12 teaspoons of sugar and a typical container of fruit yogurt has eight sealed the refined sugar deal for me. No more, I say. It's just not worth it.

Now here comes the lowdown on fat. Some say the fat we eat is the fat we wear. Perhaps. But one thing is for sure -- fat kills. That's Fit blogger Rigel Gregg wrote a May 24 post all about it, documenting five ways wearing fat can kill us -- it strains our heart and raises our insulin, leading to increased risk of heart disease and diabetes, for example. Now I'm here to clue you in on the fat hiding in more of our favorite foods.

Here goes.

I have heard many times that being obese or overweight increases the risk of developing breast cancer. It also has been said that it shortens the time between the return of the disease.

Why is this? It might be because of a hormone in our bodies called leptin.

Researchers are doing experiments on mice that might prove to be an important influence in developing drugs that target the mechanism that causes obese individuals to have a higher risk of the disease.

Italian researchers speaking at the Experimental Biology 2007 in Washington, DC, report evidence on how leptin, a hormone found in fat cells, significantly influences breast cancer development and progression in mice.

Leptin sends messages to the body that no more food is needed, a process that might not work well for those that are overweight or obese. Leptin also is involved with cell differentiation and proliferation in the body. Leptin has demonstrated to play a significant role in promoting breast cancer in obese women by increasing the amount of estrogen in the breast tissue.

Even though these are experiments done only on mice at this point, this learning process is what leads to new drugs and targeted therapies.

Don't delay. There's no better time than the present to get your weight in check. Especiallly now that The American Cancer Society is reporting that maintaining a healthy weight is at the top of their cancer prevention list.

"We know that obesity is related to a number of different cancers, breast cancer among post-menopausal women, colon cancer, esophageal, kidney cancer," says Colleen Doyle of American Cancer Society spokeswoman.

This makes the ACS recommendations more urgent than ever.

The ACS urges individuals to eat a diet rich in fruits, vegetables, and whole grains and to exercise at least five days per week.

There are no guarantees, of course, that these practices will hold off cancer. But "the good news is that a lot of people think they don't have any control over their risk of cancer and we're here to tell people that absolutely you do have some control," says Doyle.

It is estimated that poor diet and lack of physical activity cause about one-third of cancer deaths each year, about the same number of cancer cases caused by smoking.

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.

One out of three Americans will get cancer before they die. Who is at the highest risk?

Dr. David Nanus, an oncologist who has been treating cancer patients for over twenty years, says that "If you're obese or overweight, you have an increased incidence in a number of cancers". Nanus also tells CBS news that someone with a family history, someone who smokes, has a high fat diet and does not exercise are in the highest risk category for developing cancer in their lifetime.

According to the American Cancer Institute about one third of cancer deaths in 2006 were related to nutrition, physical inactivity and being overweight or obese -- and could have been prevented.

Nanus also says that "The biggest problem is the fear factor. People are so afraid of being diagnosed with cancer they wait. Even waiting three months can mean a difference between life and death.

An article recently published in the journal Cancer says that middle-aged men who are obese at the time of diagnoses of prostate cancer have a significantly worse overall survival than those who are not overweight.

Researchers from the University of Washington and the Fred Hutchinson Cancer Center recently conducted a clinical study to further evaluate potential associations between obesity and outcomes among patients diagnosed with prostate cancer. This study included 752 middle-aged men diagnosed with the disease.

They concluded that the men with the highest body fat had an approximate 2.5 fold increase in risk of death from prostate cancer. Also, the obese men had a 3.5 fold increased risk of metastasis.

When you plan to go on a diet or want to start eating healthier, salads seem like the perfect lunch to shed some unwanted pounds. The problem with salads is they can easily deceive the most well meaning dieter.

They say they are salads -- in a way they are -- but not in the eating healthy sense that we associate with it. Just because it has salad in the name on the menu does not mean it is healthy.

Some of you might be saying that you know this already. Believe me when I tell you that some people don't know this or are in some way in denial about the whole salad situation. A taco salad may contain greens and some tomatoes but it also can have ground meat, lots of cheeses, tortilla chips and sour cream.

Salad dressings are another problem, they can sometimes be the same amount of calories as a fast-food meal. Instead of reaching for the ranch dressing which can contain 110 calories and 12 grams of fat per tablespoon, try and make your own salad dressing so you know exactly what your putting in your salad. You can do this when dining out, restaurants usually offer vinegar and oil as a dressing choice.

A few good ideas for a healthier salad:

• Stay away from salads that have meats or cheeses
• Spice up your salad with different greens like arugula or watercress, you won't miss those creamy dressings with all that flavor
• Make your own dressing using a small amount of extra virgin olive oil, red wine vinegar and some fresh ground pepper.
• If you buy a salad-to-go in a convenience store, compare the calorie content between the light salad dressing to the creamy dressings. I have seen differences of 200 calories or more
• Skip the croutons and put in some crunching veggies instead

If you want that taco salad then go at it but if you are trying to lose weight or eat healthier then thinking about what is going into your salad can make a huge difference.

Discoveries have linked certain viruses to cancer growth. The hepatitis B virus is related to liver cancer. Women who develop cervical cancer have had a human papilloma virus (HPV) infection but not all women with HPV infection will develop cervical cancer. Stomach ulcers are likely caused by Helicobactor pylori, or H. pylori a bacteria and the ulcers can grow into cancer. Viruses attack cells in the body and once these cells are corrupted they begin to grow uncontrollably, eventually leading to cancer.

With these discoveries leads us to the knowledge that protecting the immune system in the body and keeping viruses at bay, is important in preventing cancer. Viruses enter the body through everyday activities like eating, breathing and sexual activity. Eating well, exercising and avoiding alcohol and cigarettes are good ways to keep your body's natural defenses functioning at their best. Staying protected with condoms during sexual intercourse helps protect you from sexually transmitted viruses and diseases. Learning healthy life style habits is the beginning of keeping cancer at bay. Focusing on nutrition, exercise, body weight, keeping toxins out of our bodies and our home environment ,and lowering stress will all help boost the immune system.
