Vitamins as we age

By Val Willingham
CNN Medical Producer

My friend takes a lot of vitamins.  In fact, in one day, she probably washes down the entire alphabet.  I have often wondered, as I watch her take glass after glass of water to swallow them all, why?  Is it really necessary to take that many supplements?

Nutritionists say no.   According to Katherine Tallmadge of the American Dietetic Association a multi-vitamin once a day is fine.  The best way of getting your vitamins, she says, is to eat foods that are loaded with nutrients. "Many studies are showing that vitamin supplements do not get the same results as vitamins from food," she says.   So that means eating goodies rich in calcium, Vitamin A,B, B12, C and E.   And as we age, it's even more important to get these supplements into our diets in order to stay healthy.

At any age, but especially as we get into our 30s, calcium is important.  Most people think calcium plays a bigger role in our golden years, but doctors say the more calcium you put in your body as a young adult, the stronger your bones will be as you get older. That's because as we reach 30 we begin to lose bone and muscle mass.   So fill up the breakfast table with low-fat milks and yogurts. And look for foods rich in magnesium and vitamin K for muscles. And don't forget vitamin D.  It helps your body absorb calcium into the bones.  You can get it from sunshine, but getting enough of it that way can be a challenge with a busy schedule.   In fact Tallmadge says, "vitamin D is hard enough to get in food...vitamin d is the only nutrient I recommend that you get from a supplement."

Also in your 40s and 50s start thinking about your heart.  Tallmadge notes, "a big factor is preventing heart diseases.  I would say the B vitamins are very important – folic acid, vitamin B 12 – those B vitamins are very important for keeping homocysteine levels down. which is an emerging risk factor for heart disease."

So turn to whole grains, broccoli and low-fat animal products, like lean meat and chicken.  All of these can help keep the circulation system healthy.

And of course, eat lots of veggies and fruits.  And don't forget the omega 3 fatty acids found in oily fish, walnuts and flax seed.  They're also important for prevention of heart disease because they can reduce inflammation, blood clots and keep blood pressure down.  They can also be important for the brain.  Studies have shown people with high Omega three diets, have less depression, and fewer cases of dementia and Alzheimer's.  

As for all the vitamin supplements, talk to your doctor.  They aren't necessarily bad for you, but taking too much of one vitamin or combination of vitamins could cause problems.  Nutritionists say, balance it out.  It could help you feel healthier and cut down on your vitamin bill.

Do you take vitamins... which ones and why?  We'd like to hear about it.

Obama's health by the numbers

By Tim Langmaid
CNN Medical Managing Editor

A week ago today, Sen. John McCain, the presumptive Republican presidential nominee, allowed journalists, including Dr. Sanjay Gupta, to view hundreds of pages of his medical records, dating back about eight years. This week Sen. Barack Obama, the Democratic front-runner, released a very brief summary of his medical history.

The summary was written by Dr. David L. Scheiner, who notes he has been Obama's physician for more than 21 years. Neither candidate is required to divulge details about his health to the public. Both have. There's been a great deal of interest in McCain's health, primarily because of his bouts with skin cancer. For Obama, there have been fewer questions, but most have focused on his history with cigarettes.

You can read the doctor's one-page summary of Obama's health by clicking here.  Below are the highlights:

Obama is kicking his cigarette habit. Scheiner notes the senator has been an "intermittent" smoker but doesn't mention when he began smoking or how many cigarettes, on average, he smoked a day. But he confirms what Obama has mentioned on the campaign trail: The senator is using Nicorette gum with success. Smoking is more than just an obvious health issue for Obama – the senator's mother died of ovarian cancer and his grandfather died of prostate cancer.

Scheiner shares some lab results from Obama's most recent physical exam (January 15, 2007). The numbers indicate the 46-year-old is in very good health:

– Cholesterol 173   (less than 200 is considered "desirable" by the American Heart Association)
– HDL 68   (more than 60 offers some protection against heart disease according to AHA)
– LDL 96   (less than 100 is considered "optimal," the AHA says)
– Triglycerides 44   (less than 150 is normal)
– PSA 0.6   (lower than 2.6 is considered low/good according to the National Cancer Institute)

The doctor notes that Obama's blood pressure was a low 90 over 60 when he measured it during his exam almost a year a half ago. His electrocardiogram, or EKG, a measure of the heart’s electrical activity, was normal too. Scheiner also writes that, at the time, Obama was exercising regularly and often jogging three miles a day. That healthy habit may be getting tested now by the demands of the campaign trail.
