4. Energy Drinks
Energy drinks may make you feel invincible for a few hours, but they are doing steady damage inside your body. For one thing, they are made primarily of sugar, caffeine, and artificial dyes, which can spike your blood pressure and blood sugar at the same time.
People have died from drinking too many energy drinks, especially of heart problems and seizures. Anything that weakens the systems inside your body can leave the door open for cancer. Plus, sugar is cancer’s favorite food and too many energy drinks leave a lot of it available to feed those killer cells.
