Why fluoride is ok in food and not in toothpaste ?

I don't mean to relauch the debate agisn but I just need a litle point of clarification :

Well, why fluoride is considered dangerous in toothpaste and not when in our foods ?

I mean I think we are taking in fluoride on a daily basis when you look lots of foods contain it....... but wait it seems that the food listed are processed foods:
