6. Potato Chips
This very popular snack is one of the main reasons why there are so many obese people. You can eat just one potato chip a day and it will be enough for you to gain 2 pounds per year. It was confirmed by a study, which was published in the New England Journal of medicine. Potato chips are saturated by trans-fats which should be at the top of your list of things to avoid eating. Trans-fats increase the level of cholesterol. Besides, a lot of sodium is a basic reason why many people have too high blood pressure.
