Marta Zaraska (IG: @mzaraska) is a Polish-Canadian science journalist published in the Washington Post, Scientific American, New Scientist, the Atlantic, and Discover.

Her first book, "Meathooked: The History and Science of Our 2.5-Million Year Obsession with Meat" was chosen by the journal Nature as one of "the best science picks" in 2016.

Her second book, "Growing Young: How Friendship, Optimism and Kindness Can Help You Live to 100" is a Globe and Mail bestseller. It's a research-driven case for why optimism, kindness, and strong social networks will keep us living longer than any fitness tracker or superfood.
