Actor Robert Downey, Jr., who is best known for playing Iron-Man and Sherlock Holmes in films, is now advocating climate smart food choices! Downey, Jr. has teamed up with bestselling author Thomas Kostigen to write a new book titled 'Cool Food: Erasing Your Carbon Footprint One Bite at a Time'.
It's noted that this is the first non-fiction book by Downey, Jr. The actor got interested to learn about nutrition after his Marvel run as Iron-Man, to prepare for the rigours of that role.
