I'll be honest. I'm not a big fan of multivitamins. I don't think they're a bad thing and I would never try to talk someone out of taking them. However, if you eat a nutritious and varied diet, popping a pill seems a bit redundant to me. Kind of like putting in your contact lenses and then putting on a pair of glasses to make sure you can really, really see.

Researchers recently found that, while multivitamins are unlikely to do any harm, supplements don't help older women fight off heart disease and cancer. The results seem to confirm other recent studies that say some supplements don't have the same cancer-fighting abilities as the vitamins do when found in food.

As with most studies, other researchers have stepped forward to point out flaws. Be that as it may, it makes me wonder if we're expecting a bit much from our multivitamins. Since when did multivitamins have to don their superhero suits and fight off all diseases?

Multivitamins are intended to be a part of a healthy lifestyle that includes a healthy diet and regular exercise. They aren't a free pass that gives you the option of eating nothing but junk and they aren't a magic potion that will ward off disease.

Sweet potatoes are a nutritional gold mine. High in vitamin A, vitamin C, fiber, iron and other powerful nutrients, choosing sweet potatoes over other varieties is a no-brainer. This Sweet Stuffed Sweet Potato recipe is very easy to make, and the sweet flavor makes it taste a little more like dessert than a vegetable.

The recipe can be found on page 8 of my online recipe book at Fitzness.com. I make it often at family meals, but sometimes I just cut the ingredients down and whip some up for myself. Give it a try! I hope you'll enjoy it as much as I do.

Diet Coke Plus is supposed to include quite a few vitamins and minerals right in with your favorite soda. But the FDA and the Coca Cola company are in the middle of a he-said/she-said type of battle. Coca Cola stands by its product, but the FDA says it doesn't meet their standards.

In my opinion, the whole concept of getting vitamins and minerals from soda is ridiculous. If you want a diet soda, then go ahead and treat yourself. But know that it's a treat. Soda just shouldn't be considered part of your daily nutrition no matter how many vitamins and minerals are added into the mix. It's the liquid equivalent of those glorified candy bars that are considered health food because they have a little extra protein thrown in.

You're much better of getting your vitamins and minerals from natural sources, such as fruits and vegetables.

If you have a slice of delicious cake, would you think it's OK to chow down the whole cake in one sitting? Of course not. Common sense would tell you that a whole cake is just too much. Unfortunately, when it comes to health advice, not everybody uses common sense.

I recently wrote a post about the benefits vitamin D can have on heart health. That's only one of the perks of vitamin D that has been in the press lately. Now many people -- buying into the vitamin D kick hook, line and sinker -- are buying high-dosage vitamin D supplements from pharmacies and health food stores.

There is no science that says high doses of vitamin D are necessary. And why waste your money on a supplement when vitamin D is so readily available from other sources? Sunlight is your best source, but again, it's important to be reasonable. You don't want to spend too much time in the sun without the protection of sunblock, so a few short 10-15 minute walks outside each week will do. Vitamin D is also available in fortified foods such as milk, some cereals, and orange juice, and it's naturally found in salmon and other oil-rich fish.

No monkey business here -- bananas are the real thing. Like corn, eggs, salmon, and spinach they are great source of vitamin B6, a little something known to treat the colon well.

A healthy colon is just one reason to load up on bananas, says RealAge. Here's another: Bananas help ward off Parkinson's disease and depression too.

Eating Well experts suggest you dress up your bananas like this: Add some protein to your yellow fruit with mini-rice cake stacks, or add chocolate for a quick and easy dessert (it's OK, chocolate isn't so bad in moderation), and whip up some spicy banana ketchup for your burgers.

Got any banana fixes you'd like to share?

Nearly every time my son and I go grocery shopping, he begs me to buy children's vitamins. I know parents tend to disagree when it comes to children's vitamins. Personally, while I don't think they're harmful, I don't think they're necessary. My son eats plenty of fruits and vegetables, he gets sufficient calcium from milk, yogurt, and fortified orange juice, and he eats a broad range of other healthy foods as well.

But my kid LOVES his candy. And I'm quite certain that is why he wants those gummy vitamins he sees in the store so badly.

Angie over at ParentDish recently wrote about a study regarding children's vitamins. The study reviewed 14 types of vitamins and found that only five of the reviewed brands had the 12 essential vitamins you would expect. Some brands had as little as four vitamins. The researchers state that the vitamins are little better than candy.

Caught an old rerun of an Oprah show last night. Watched just long enough to hear a very enthusiastic doctor offering advice on vitamin D. All women need to have their vitamin D levels checked, she said, because most women don't get enough. And if we're not getting enough, we need to know this so we can make necessary adjustments.

Vitamin D is critical to our health -- a deficiency can result in bone problems, cancer, high blood pressure, depression, and immune-system disorders such as multiple sclerosis, rheumatoid arthritis. and diabetes. We need about 2,000 international units of it each day, says the good doctor, not the 400 currently recommended by the FDA.

Oprah said she's had her vitamin D levels checked. They were low. No surprise. So she started taking a supplement to bump her into a better range. Supplements are good. So is the sun -- just 15 minutes per day, and don't burn. And of course, vitamin D rich foods, like wild salmon, shrimp, skim and low-fat milk, Shittake mushrooms, fortified yogurts, and fortified cereals.

Do you know your vitamin D levels? I don't. But I should.

Research shows that women who drink even small amounts of alcohol can spike their breast cancer risk. But getting enough folic acid can help.

A long-term Nurses' Health Study shows that the proper intake of the B vitamin may reduce breast cancer risk for those who consume more than the equivalent of one glass of wine per day.

Want to get enough folic acid in your diet? Ask your doctor about a multivitamin containing the recommended amount or make a commitment to consuming lots of fortified cereals, leafy greens, citrus fruits, and juice.

We've all experienced "brain failure," that embarrassing moment when you can't remember something totally mundane and regular -- like how to spell a simple word or where you parked your car. Having a better memory is something pretty much everybody would enjoy, especially when it comes to doing your best at work. Giving your noodle a boost is something you can do in as little as 30 seconds, so there's really no reason you can't fit an exercise or two into your daily routine. Try one of these exercises from Natural Health to get started:

Ugh, supplements. For a lot of people they're a "must have" for a healthy diet, and although I don't disagree, I'm also really bad at taking them because it's just so confusing determining what exactly I need -- the list of "recommended" supplements is at least a mile long it seems! But a nutritionally-complete diet is almost impossible to come by through food alone these days, and many supplements can give an extra boost of valuable disease and age-fighting properties to help fitness goals be that much easier to both achieve and maintain. But if you're like me and find yourself either overwhelmed or just generally intimidated by the prospect of taking regular supplements, this list of the 5 most valuable supplements compiled by experts for Natural Health magazine could be a big help! Here they are:

So I need a certain amount of direct sunlight every day in order to soak up some necessary vitamin D. But I also need to wear sunscreen at all times to protect my skin from the sun's dangerous rays. Both bits of wisdom make sense. And they don't make sense at all. I mean, if I wear sunscreen all the time, how will I get my vitamin D? And if I hang out in the sun for even 10 minutes without lathering up, I'll get burned. Trust me, I will.

It's controversial, this sun vs. sunscreen predicament. The National Institutes of Health suggests we get five to 30 minutes of sun, free from sunblock, a few times per week to avoid vitamin D deficiencies. It keeps bones strong, helps prevent heart disease, and may ward off cancer. These are biggies. But wearing sunscreen every day is big too. It's the only way to keep skin cancer at bay.

Err on the side of protecting your skin, says popular opinion. Just count on getting your vitamin D from walking to and from your car, the grocery store, your mailbox a few times a week. You can get it from food sources too, like fortified breakfast cereals and milk, or from a dietary supplement. And if you're concerned you may be vitamin D deficient, consult your physician.

Q. Fitzy. I work out a few times a week and eat pretty well, but "six-pack" abs have always escaped me. I do plenty of crunches, but nothing seems to bring me even close to the abs I see on the cover of Men's Health magazine. What is the secret to it? Chase

A. Ahhhh Chase. The elusive six pack. Doesn't every body wish for that? Yes ... almost everybody does. Very few actually achieve it, though. This is the deal Chase, the "secret," if you will. If you want to look like an athlete, you're going to have to behave like an athlete. Train ridiculously hard and eat ridiculously well. Six-pack abs are a sign of elite fitness for sure, and you're probably not going to earn them working out a "few times a week and eating pretty well."

Last fall, my son played soccer. Week after week I was disappointed in the snacks that parents brought for the kids. Now it's baseball season and I'm seeing the same trend. My son has been given sugary juices, "sports" drinks that are loaded with sugar, cookies, chips, and snack cakes. I'm not completely opposed to kids having treats from time to time. But I think that, after being active, kids need some decent nutrition.

While adult and competitive athletes may need nutritional programs designed specifically to boost performance, kids don't need anything that rigid. All kids need is good nutrition to get the most out of their activities. Here are a few tips:

• Eating a healthy diet with lots of fruits and vegetables, whole grains, beneficial fats, and lean protein will give your young athletes all the fuel they need. A daily multi-vitamin is also a good idea. Sports bars, protein gels, and other specialized foods aren't necessary.
• It's important to keep your young athlete hydrated. Young children, in particular, are prone to dehydration because their bodies produce more heat yet sweat less. But water is sufficient for youth sports. Unless the activity is constant and extends beyond one hour, drinks with added electrolytes just aren't necessary. Besides, many sports drinks offer nothing more than artificial coloring, artificial flavors, sodium, and high fructose corn syrup.
• While it's not an issue with boys my son's age, I know high-school and college-age athletes may be tempted by the powders and drinks guaranteed to pump them up. The problem is that dietary supplements (which is what those sports aids are considered) aren't screened by the FDA so their efficacy and safety aren't monitored. While many may be harmless and some might even be effective, there's risk involved.
  

Good nutrition and consistent exercise are all any young athlete needs to stay at the top of their game.

According to an Italian study, from which results were published in past issue of the journal CANCER, folic acid supplements may prevent cancer progression and promote regression of the disease.

Researchers found that 31 of 43 patients with the precancerous laryngeal lesion known as leucoplakia showed a 50 percent or greater reduction in the size of the lesion after taking folate supplements for six months. And, for the remaining 12 patients, they amazingly did not show any sign of the original lesion after the six month period.

Folate is sometimes more widely known as vitamin B-9, which is found in abundance in fruits and vegetables, as well as several types of beans. Plus, many multi-vitamins offer close to the recommended daily value of folate.

For over 30 years, the medical community has prescribed vitamin D to patients with kidney disease in order to help maintain strong bones. But a new meta-analysis of many different studies concludes that this practice doesn't really help in achieving the goal it's supposed to.

The whole reason why this is prescribed was because diseased kidneys can't remove excess phosphorous from the body. Blood calcium drops due to the fact that phosphorous keeps building up. As a result, calcium is removed from the bones, hence the reason they become so weakened. This is how vitamin D became so prevalent, but the fact of the matter is that they really don't know if it helps their condition at all.

Risk of death, bone problems and other issues did not consistently change over time, even when they took the supplement compounds. In an editorial with the analysis, one associate professor of medicine out of Canada states this is evidence enough to challenge "many of our common practices." He continues by conceding that more research still needs to be done. Even so, the researchers say patients should continue following prescriptions, and more importantly pay attention to preventive measures.
