Los Angeles, April 5 (IANS): Best known for playing Iron-Man and Sherlock Holmes on the big screen, Robert Downey, Jr. has now turned to promoting climate-smart food choices. The Hollywood star has teamed up with bestselling author Thomas Kostigen to write “Cool Food: Erasing Your Carbon Footprint One Bite at a Time.”

Blackstone Publishing has acquired the rights to the book, which its authors say will provide a smart, accessible and game-changing roadmap for making climate-solving food choices, ‘Deadline’ reports.

The deal marks the first major non-fiction book from Downey, Jr., who has delved into nutrition since the start of his Marvel run as Iron-Man to prepare for the rigors of that role.

‘Deadline’ Notes: “While there has been a preoccupation in Hollywood with reducing the carbon footprint, doing it through diet seems like an innovative wrinkle.” Blackstone has not set a release date.

“Our best global food future doesn’t require hand-twisting, fad diets or radical shaming – just a shift in perspective to uncover the many solutions in plain sight,” said Downey, Jr.. “With Kostigen in the cockpit and Blackstone’s formidable ground control, this should be an actionable adventure. Join us.”

Kostigen added: “As the great Yogi Berra once said, ‘The future isn’t what it used to be.’ More and more, we are presented with forecasts of worsening climate.

Speaking about the book, he pointed out that “Cool Food” “shows how we can change that perspective for the better by making a few different choices at the grocery store, trying something new on the restaurant menu, and keeping an eye out for foods that store more carbon in the soil rather than polluting the air.”
