Pizza just might have the power to fight cancer -- not the pizza loaded with cheese and pepperoni and tons of tempting toppings, the kind that may have your mouth watering at this very moment. But a version of pizza as we know it may fend off heart disease, obesity, and cancer.

The secret is in the crust -- the cooking of the crust, that is.

Think about this:

It seems baking pizza faster and at higher temperatures can release disease-fighting antioxidants. And it's this one small change to pizza preparation that has scientists at the University of Maryland claiming there is such a thing as a healthy pizza.

Scientists baked pizza at 500 degrees for six minutes and were able to increase antioxidant levels 100 percent. They used whole wheat dough, already high in antioxidants, and let it rise overnight before using their hotter, quicker cooking approach.

One researcher says this study is more a lab curiosity than anything else and might not really lead to a healthier pizza -- because it's unlikely pizza joints will change cooking methods to turn out healthier products.

If you are tempted to try this technique, be aware that the toxin acrylamide can be released if the pizza is baked too long. And don't forget to cut way back on those tasty toppers.

Ever since revealing her breast cancer had recurred, there has been speculation about a spread from Elizabeth Edwards' rib -- the initial metastasis -- to other spots in her body.

Last night, on the CBS news program 60 Minutes, Edwards told Katie Couric that a hot spot has been detected in her right hip. But doctors believe it is too small to pose a new health risk, she reports.

"There are a couple of hot spots, on the bone scan, in my right hip, for example," she said. "And one of the questions is whether or not to do radiation to reduce the size of that -- of the cancer in that location -- and for fear that it might weaken my bone and that I might break my hip. But their consensus was that it was too small an area for that to be a risk."

In addition to discussion about the cancer itself, Edwards and her husband John defended their decision to stick with the presidential race. Edwards said she just cannot deny her husband the chance to be president.

"That would be my legacy, wouldn't it, Katie?" Edwards said to Couric. "That I'd taken out this fine man from -- from the possibility of -- of giving a great service. I mean, I don't want that to be my legacy."

Presidential candidate John Edwards and his wife Elizabeth will appear tonight on 60 Minutes where they will publicly discuss with Katie Couric Elizabeth's newest cancer diagnosis and their decision to continue on in the presidential race.

Elizabeth, 57 and first diagnosed with breast cancer in November 2004, shared Thursday that her cancer has returned, this time in her bones. Considered stage four and treatable -- but not curable -- her cancer has generated much discussion and awareness about the workings of this life-threatening disease.

Research published in the international medical journal Addiction showed that moderate exercise, such as walking, significantly reduced the intensity of smokers' nicotine withdrawal symptoms. Just five minutes of exercise can get the smokers past that need for a nicotine fix.

Nearly anything that distracts people from smoking is thought to help, but scientists have long suspected that exercise might have a more potent effect. Exercise could produce a mood-enhancing hormone dopamine, which could, in turn, reduce the smokers' nicotine dependence.

When you're dying for a cigarette, try some exercises or a walk to get past the craving. Remember, if you are trying to quit, a craving will only last about three minutes!

For those of you living for the moment, you are about to lose 60 whole minutes come Sunday when Daylight-saving time strikes once again.

This may throw you off a bit if you are one to maximize every second, minute, and hour you are afforded in this tenuous life. And while I can't offer you any secrets for recapturing this lost time, I can share some thoughts, compliments of professional organizer Linda Richards of Organize and More, on how you might compensate for Sunday's lost hour.

Think about this:

• Go to bed 15 minutes earlier and get up 15 minutes earlier starting a few days before the time change.
• Move any important meetings to later in the week so you body isn't as tired.
• Snack on healthy foods such as fruits and nuts to replenish energy.
• Shorten your to-do list to your top three to five priorities.
• Print out a copy of your calendar and appointments for March and make sure your computer has a patch to handle the earlier time change this year.
  

CBS 60 Minutes newsman Ed Bradley lost his life to leukemia on November 9, 2006. And ever since news of his death reached the world, reactions have been overwhelming -- and like nothing correspondent Lesley Stahl has even seen.

"I've been around here a long time and there was a quality of reaction from the public that was personal in a way I can't explain and everyone here has had the same thing," she said. "We have all been flooded with e-mails."

Bradley was the king, says his former correspondent Bob Simon. "He had the most authoritative presence and style on the broadcast and that's not replaceable," he said.

Faced with the huge loss of Bradley, CBS won't even bother to replace him in the middle of the TV season. Instead, his workload will be spread around -- a unique arrangement for 60 Minutes -- for as long as it takes to find the next full-time person armed with the ability to take on Bradley's correspondent role.

Bradley's death also robs 60 Minutes of its only on-screen black correspondent. And while it's important to represent diversity, the powers that be believe it would be a mistake to fill the spot with someone just for the sake of addressing the issue.

So those at CBS will just wait for the right person to come along -- while they collectively grieve for the right person they just lost.

Calorie counting may be a bit tedious for some -- like me -- but for others, it may be just the ticket for the management of weight and overall health.

Charles Stuart Platkin, author of the new book The Diet Detective's Count Down, takes calorie counting one step further and offers the exercise equivalent of a nutritional label.

His 341-page book offers charts that detail the number of calories, fats, and carbohydrates in more than 7,500 foods and drinks and then translates these details into what it takes, in terms of minutes, to burn the calories with walking, running, biking, swimming, yoga, or dance.

Platkin, a syndicated nutrition and fitness columnist, says he is not trying to encourage people to count every calorie consumed in a day and to exercise until each calorie melts away. His goal is to help those who exceed their daily calorie budget -- the number of calories they can eat each day without gaining weight.

The Count Down goes like this -- you consume one martini at your New Year's celebration, pushing you beyond your allotted calories for the day. All you have to do is walk it off the next day in a mere 71 minutes. Or you can run it off in just 39 minutes. If a single cracker with one slice of Genoa salami and cheese tempts your palate, go for it -- then plunge into a 55-minute yoga class.

Before taking a stab at the diet detective's approach, there are several considerations to take into account. First, the book is based on a 155-pound person. A person carrying more weight would burn more calories per minute, and a person carrying less weight would burn less. Second, a person's basal metabolic rate (BMR) must be calculated -- Platkin offers formulas for this task -- so it's clear how much activity output is required by each person. And third, the exercise equivalents are based on scientifically researched metabolic equivalent tables that try to measure what is being burned versus a person's resting metabolic rate. So this is not just a crazy gimmick. It's science -- with a touch of personal perspective too.

Platkin, clinically obese for most of his life, lost 50 pounds a few years ago and came to realize that people just don't know what a calorie is. He wishes the U.S. Federal Drug Administration (FDA) would include exercise recommendations on food labels and says, "I think that we are so confused in general as a population as to what's healthy and what's not, we confuse the term healthy with low-calorie. Sometimes they don't mesh. There's so much confusion out there that I think that it needs to be more defined. We need to have some sort of reference points so that people can make decisions before they consume."

Until the FDA delivers on Platkin's wish, he is taking matters into his own hands for those who choose to borrow from his wisdom.

Some of his wisdom includes eating calorie bargains (air-popped popcorn) instead of calorie rip-offs (potato chips) and substituting mustard for mayonnaise on a burger -- it will save 2,000 calories per month for someone who eats fast food three times per week.

Platkin's hope is simple -- he wants people to ask themselves whether certain foods are worth the cost. Is it worth a 54-minute run to burn the 510 calories in a McDonald's Quarter Pounder with Cheese? How about a 144-minute walk to rid yourself of a Subway six-inch Meatball Marinara sandwich?

It's a worthy hope, I think -- although this method is still a bit tedious for me. I think I will stick with my own formula -- eating moderate portions of what I enjoy and intensely exercising several times per week. I don't need to know how many calories I am consuming. I don't even need to know how much I weigh. As long as my clothes fit and my fitness routine keeps me sweating, I'll be a happy girl.

My port -- that thing that pops up from under the skin on my collarbone, that thing that by default stays in place because I can't decide whether or not to remove it -- is now officially in maintenance mode, now that my treatment for breast cancer is complete. My last Herceptin infusion was on June 28. And my first port flush was today. For as long as I keep my port -- and for as long as it has no real use -- I must have it flushed one time each month. So today, I strolled into the cancer infusion center where I've spent many hours and this time spent just a few minutes -- enough time for my usual chemo nurse to puncture the skin on top of my port, push through a rather large needle, and inject a dose of blood thinner into the lines of the port to keep clots away. The whole procedure was harmless, painless, no big deal at all. And I will return one month from today for a repeat performance.

One day these once-a-month visits may become a hassle. After all, I have to find a place for this appointment in my already-busy schedule and find childcare for my kids and find a place to park. I have to numb my port and endure a needle stick and sometimes fight traffic to get home. And the whole trip to and from the cancer center takes longer than the procedure itself. Clearly, this may be a waste of time for a port I don't even need right now. But at the moment, this visit is just what I need while I sort out the details of my post-treatment world. I need to go back to the infusion center. I need the comfort of the drive. I need to feel part of the chemo community. I need medical people swirling around me. I need a bit of hand holding. For now anyway.
