[HIGHLIGHTS] Why does aluminum foil have two sides with different surfaces?

Aluminum foil has two different-looking sides. One is matt, the other shiny.

The different sides of the aluminum foil are created during production. The use of aluminum foil is not particularly good for the environment. It can also be unhealthy for the body if used too much or incorrectly. Some foods can absorb aluminum if they are wrapped in it. The European Food Safety Authority recommends not consuming more than one milligram of aluminum per week. For most people it is more. Organ, nerve and bone damage can result.
