Nuts and olive oil are clearly good diet choices. But ever wonder which one is better? RealAge names nuts as the healthier option.

In a year-long study, people who ate a Mediterranean diet and added an extra ounce of nuts (a small handful) had a lower rate of metabolic syndrome compared to those who ate the same diet but upped their olive oil intake by four to five ounces per day. The theory behind this finding is that olive oil is extracted from olives, but nuts are a whole food and have more fiber, protein and minerals. Olive oil is still important -- just like nuts do, it helps reduce abdominal fat more than low-fat diets do.

A healthy diet, exercise and regular physicals can help prevent metabolic syndrome, a cluster of conditions that occur together, increasing your risk of heart disease, stroke and diabetes. Conditions include obesity (mostly the "apple shape"), elevated blood pressure, elevated level of blood fat (triglycerides), a low level of good cholesterol (HDL) and resistance to insulin.

Pour yourself a piping hot cup of cocoa if you get the chance today. There's nothing better for warming your spirits on what might be a chilly day in your neck of the woods. Just two rules: Make it sugar-free, and go easy on the creamy toppings.

The great thing about hot cocoa is that while you sip your way to a toastier spirit, you'll also be helping your heart. Just ask researchers from Yale, who say that downing a cup of the chocolate stuff causes blood vessels to temporarily dilate so the heart doesn't need to pump as hard. The end result, says the crew at Ladies Home Journal: A blood pressure drop to the tune of six points (only three points if your cup contains sugar). Opt for naturally-processed cocoa powder over the Dutch-processed variety, and you'll get even more antioxidants for even better blood flow.

Go ahead -- indulge. It's Christmas. You deserve a treat. And a healthy heart too.

I was a cheerleader back in my high school days. When my squad was training for competitions, we really worked out long and hard. Many times, the muscles in our legs would visibly shake with strain. Our coach, restricted from recommending vitamins or anything of that sort, always brought bananas with her to practice to help us with muscle weakness and muscle cramps. Bananas aren't my favorite fruit, but I have to admit that they helped.

While bananas are a decent source of potassium, there are many other options. Potassium-rich foods are important for your diet. Not only do they help with muscle cramps, but they can also have a positive effect on blood pressure. Good sources include:

• Avocado
• Baked potato with skin
• Edamame
• Papaya
• Sweet potato
• Salmon
• Tomato sauce
• Winter squash
• Cantaloupe
• Dried apricots

If you want to follow the latest fashion trends, you should go for it. Want to get that trendy haircut? More power to you. You should get in on the diet and fitness trend too -- because high blood pressure is on the rise in America, and we're pretty sure this is one trend you'll want to avoid.

The numbers are climbing -- from 1998-1994 24.4% of Americans had high blood pressure; more recent numbers show that 28.9% are now diagnosed with the condition. On the upside, more people are being properly treated, so deaths related to blood pressure have decreased.

While you can't control some risk factors for high blood pressure -- such as family history, race, and age -- there are things that you can control. Maintain a healthy weight, exercise regularly, eat a healthful diet that's low in sodium, avoid drinking alcohol, and keep your stress level under control.

It should be no surprise that a nutritious diet and regular exercise help us live longer. That's why these two must-haves appear in a top 10 list created by Dr. G. Medical Examiner.

Day in and day out, Dr. G. determines how recently departed people died. Sounds like a morbid job, doesn't it? It's actually pretty amazing if you watch her show, though. She takes clues from everything and sometimes comes to unexpected conclusions. For families that have lost loved ones without much warning, I expect that the explanation of their loved one's death helps to give them closure.

An expert in death, Dr. G. has come out with a book to help preserve life. Discovery Health has her top 10 ways not to die. Here are a few of her tips:

• Know your numbers. Keep your BMI in a healthy range by exercising and eating right. Check your blood pressure often. Have your cholesterol and blood sugar levels tested.
• Listen to your body. Don't ignore unusual pains or aches ... tell your doctor about any concerns you have.
• Use as instructed. Take medications according to your doctor's instructions.

When you were little, your mom probably made sure you got your vitamin C to help fend off those nasty bugs that float around classrooms. But recent research shows that adults have good reason to get their vitamin C as well.

At their Conference of the Council for High Blood Pressure Research, the American Heart Association revealed that vitamin C has a positive effect on blood pressure. The practical applications aren't yet known but in the study, high doses of vitamin C resulted in an average seven percent drop in blood pressure.

While it's not reasonable for you to take high doses of vitamin C like those administered in the study, you can be sure to incorporate lots of healthful foods that are rich in vitamin C. Choices include citrus fruits, broccoli, greens, and melon.

Keep lifting the fork to your mouth and you'll have to fork over some cash. This is essentially the message the state of Alabama is sending out to its 37,000+ employees.

The state has already had a policy in place where smokers can either quit their habits or they must contribute to the costs of their health insurance. Recently state employees were told that they have a year to get their BMI under 35 or else they'll be charged $25 per month toward their insurance costs.

The state also has an upcoming plan in place for 2010 where, if state employees don't take free health screenings the state offers for them, they'll also be charged. If employees take the screening and conditions such as high blood pressure or high cholesterol are found, the employees will be offered free doctor visits and wellness programs to help improve the problem. A year later, they'll be screened again and if there's no improvement, they will be charged, too.
