Some health rules stand the test of time -- and some are made to be broken.
We quizzed TODAY Health readers on eight health myths and facts, and TODAY contributor Keri Glassman from Women's Health magazine shared the real answers with TODAY's Natalie Morales on Wednesday. How did you do? Read on for health myths and facts.
1. Getting a flu vaccination is one of the best ways to avoid getting the flu.
69 percent said: True.
2. Flossing is good for your heart.
91 percent said: True.
FALSE: "The new thought is, what happens in your mouth, stays in your mouth," Glassman told TODAY. "There is no clear evidence that gum disease causes heart disease. Of course, we should still be flossing away, to reduce gum disease and, of course, also to reduce bad breath!"
3. Breakfast is the most important meal of the day.
94 percent said: True.
4. Popping a daily multivitamin is a smart habit.
70 percent said: True.
5. Coffee is a great source of antioxidants.
67 percent said: True.
6. Do not eat soy if you or a family member has breast cancer.
30 percent said: True.
FALSE: Recent studies have shown that small amounts of "real" -- ie, unprocessed -- soy is beneficial, Glassman said.
7. Fat-free salad dressing is the best choice.
18 percent said: True.
FALSE: "We now know that fat is healthy for us for multiple reasons," Glassman said. "That does not mean you should go slathering on the ranch dressing. Add a portion of a clear salad dressing where the base is a healthy fat. And if you like that creamy salad dressing, I tell people to get those heart healthy fats from avocado and mix it with balsamic vinegar; it makes a nice, creamy dressing."
8. Yoga is gentle on the body.
55 percent said: True.
