We know SO much more about our health and our bodies than we did 30 years ago...or even five years ago. But there are still plenty of health myths that people still SWEAR BY even though they've been totally debunked.
1. Eating fatty foods makes you fat. Just because it's called "fat" doesn't mean it immediately makes you FAT . . . as long as you eat it in moderation. Anything can make you fat when you eat too much of it.
2. All carbs are bad for you. Over the past few decades, people have learned that carbs are bad . . . but not ALL carbs are bad. Processed sugars are bad . . . oats and fruits and other complex carbs are good for you.
3. Gluten-free foods are automatically healthy. We're squarely in the middle of the gluten-free craze, and it IS healthy to cut gluten if you have Celiac Disease . . . but gluten-free doesn't automatically equal healthy. One example: Soda is gluten-free.
4. There's something wrong with you if you don't poop regularly. There's no such thing as one schedule that's right or healthy for everyone.
5. You can get rid of belly fat by doing crunches. Science has proven you can't spot-reduce fat. Working out one part of your body won't make that part get less fat. Only cutting calories and exercising to drop fat will make you less fat.
