Many of us have heard facts about certain foods that we believed to be true — only to discover later that these were a myth. Like, for example, the fact that restricting calories and following a gluten-free diet can do more harm than good for your health. It’s challenging enough trying to keep a healthy weight and eat right, and getting misinformation about health and nutrition can give you yet another reason to worry.

We at Bright Side believe that health-related facts should be backed up by science. We’ve done our research to prepare this list of popular foods that might not be as healthy as you thought.

Plain oatmeal may seem like a good choice. It’s low in calories, yet loaded with fiber and protein. However, adding a spoonful of peanut butter or some almonds will not only make it more nutritious, but it will also help you to feel full for longer.

What foods on this list surprised you the most? Do you know of any other health myths that you’d like to share with other Bright Siders?
