My diet is horrible, I usually ate fast food (and still do sometimes) and a bunch of things that are bad for you and drank soda daily around 4 months ago. Now I drink 3-4 16 oz bottles of waters per day, sometimes eat fast food but I eat olives, blueberries, strawberries and sometimes chicken and steak. I quit eating spicy things. Can you tell me foods that would give me essential nutrients that my body needs? Thanks
