Some things are worth repeating. Other things are worth shouting from the rooftops. The importance of vitamin D is both of those things.

If you thought packaged food was bad, you should see what's in the packaging itself.

Run for your lives! The multis are coming!

That can only mean one thing, of course -- it's time for another comically feeble "exposé" of the imagined dangers, drawbacks, and pointlessness of multivitamins.

Let's face it: There's nothing "diet" about diet soda. It won't make you healthier and it won't even help you to lose weight -- and that's been proven.

Picture this:

You're the maker of a blockbuster painkiller. Sales are soaring ($2.5 billion in 2011); you're on top of the world.

Never mind that your painkiller could increase the risk of life threatening heart problems, including heart attack and stroke--and that the risk becomes greater if you use it long term.

If FDA officials had been piloting the Titanic on April 15, 1912, they might have told passengers they were looking into "reports" that an object in the water came into contact with the ship, and then put fears to rest over the remote chance that there might be any buoyancy issues.

"An apple a day keeps the doctor away."

We all know the old saying, but maybe it's time for a change of fruit.

Question: I read that many medical experts now believe that elevated levels of homocysteine--not high cholesterol--are the main cause of cardiovascular disease in Western society. Some say it's good to eat beets because they contain betaine, an important source of a molecule that accelerates the detoxification of homocysteine and transforms it into cysteine, a safe amino acid. Do you have any more information about this?

The only thing scarier than a stroke is having one and not even knowing it.

It's the so-called "silent" stroke -- given the name because it comes and goes with no symptoms.

Not on the outside, anyway.

Looking to slash your risk of a stroke? Good news, folks -- you can... and all you need to do is give yourself a heart attack instead.
