Why did we stop using tin foil?

Foil made from a thin leaf of tin was commercially available before its aluminium counterpart. Tin foil is stiffer than aluminium foil. It tends to give a slight tin taste to food wrapped in it, which is a major reason it has largely been replaced by aluminium and other materials for wrapping food.

Is it bad to wrap food in aluminum foil?

Anything acidic sparks a particularly aggressive process that dissolves layers of aluminium into food. It's safe to wrap cold food in foil, though not for long stretches of time because food has a shelf life and because aluminium in the foil will begin to leach into the food depending on ingredients like spices.

Which side of the aluminum foil should touch the food?

No, it should be fine. Aluminum rapidly oxidizes when exposed to air, forming a thin layer of aluminum oxide across the whole surface.
