11. Microwave Popcorn (with Trans Fats)
Microwave popcorn might seem like a harmless snack, but some brands add artificial trans fats and excessive salt to boost flavor. These ingredients can quietly elevate your risk of heart disease, as highlighted by the FDA. Cardiologists recommend reading ingredient labels closely or making air-popped popcorn at home. This way, you enjoy a heart-healthy crunch without the unwanted fats or sodium overload.
