Sugar. Recently started watching my sugar and oh my gooood. Canned fruits? Sugar. Whole wheat bagels? Sugar. Protein bars? Sugar. I was easily getting 100% my daily sugar without knowing and often passing it. People also drink soda like it's nothing when it has almost two days worth of sugar in it. 

Carbs fat and calories are bad too, but I feel like people severly underestimate how much sugar they intake because they think only candies have lots of sugar.

Carbs, fats and calories are bad? Do you know what calories are? That’s like saying gas is bad for your car. 

Carbs and fats are energy sources. When people stop demonizing food and learn how to eat properly with proper proportions the world will be much healthier. If you are on a diet without carbs and fats you would literally die. Google rabbit starvation.
