#4 – Cornflakes
Yep, most people are still completely unaware of the fact that a cup of cornflakes contains around 274 mg of sodium salt. While this is still the breakfast choice of many people around the world, it is highly advised that you switch to something of similar taste but far healthier – whole-grain cereals. For example, a cup of cooked oatmeal only has about 2 mg of sodium.
