I think we all have and continue to be over advised. Drink this eat that. Don't eat this and don't eat that. This supliment not that one. The list goes on and on.
Best advise is everything in moderation. Anyting in excess can be bad for us.
That is so difficult when you live in the food capital of the world!
I should weigh 500 lbs. 
However I don't!
