Is Estrogen and carcinogenics in everything we eat now?

I know of estrogen in processed ham and sort of believe it because there are alot of weird additives. Coca cola a brand well known for years had just recently got rid of a cancer related ingredient. There are supposedly estrogens in bottled water now, which i have little choice on given the many bacteria notices i get. Also mcdonalds recently get rid of its ammonia burgers. Eating some of these things including fizzy drinks has a noticeable effect on my mood and health for me.

Tl;dr How many unknown poisons do people eat and shouldn't food companies take more responsibility, And would you recognise it's overall effect in your health.
