Reducing cholesterol intake by 20 percent and getting total cholesterol levels below 180 will improve a person's risk of heart disease by 20 to 30 percent, Feltheimer notes.

Healthy diets should include at least five servings of fruits and vegetables a day, Franke declares. "This ensures that you get more vitamins and minerals, which most people don't do, and will likely increase fiber intake as well," he explains. "It will also be more filling, making you less likely to cheat and ingest more calories by nibbling on snacks."

"It's somewhat clich¿, but the most important thing to do is to eat healthy and moderate your food intake," notes Franke. "The failure many people face is thinking that diets are temporary things, and to stop once you reach a goal weight. To successfully change requires lifestyle and behavioral changes."

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
