News reports about what's healthy to eat are ever-changing. And it's difficult, even for the journalists who present the information, to research all of the claims.

Newspaper medical writer Dorsey Griffith says, "I can totally understand consumer confusion about nutrition. We are being inundated with information about various food groups. And that's because there's been an explosion in food science."

Broadcasters also face the daunting task of remaining credible…with information that often seems to contradict itself. Diana Penna, a television health reporter, points out, "There's so much out there. So many studies happening. What's good. What's bad. It's tough because you have to go through things and sometimes you look at things and say, if it's too good to be true, it probably is."

We talked with an expert to find out what's true and clear up some of the nutrition confusion…starting with the controversy over eggs.

Professor Dana Wu Wassmer, a Registered Dietitian, explains "Eggs don't raise our cholesterol level as much as we thought. So now the recommendation is you can have one egg a day without destroying your cholesterol level."

"Moderation is what we say to red wine. And yes, there seem to be some benefits to drinking moderate amounts of red wine. We definitely need a little fat in our diet. Currently, we're consuming too much, but we cannot eliminate it totally."

The common denominator in most health information is that it usually doesn't come from the medical community. And the best advice, would probably come from your doctor.
