Stuff in this book: Cheese puffs. Coffee. Sunscreen. Vapes. How bad is processed food? How sure are we? Is sunscreen safe? Should you use it? Is coffee good or bad for you? What’s your disease horoscope? What is that public pool smell made of? What happens when you overdose on fentanyl in the sun? What do cassava plants and Soviet spies have in common? When will you die?

George Zaidan reveals what will kill you, what won’t, and why—explained with humor, hilarity, hijinks, and other things that don’t begin with the letter H.

“When it comes to chemicals and our bodies, there are no simple answers. Thanks to George Zaidan, there are beautifully clear, elegant, accurate explanations. And they’re funny.  Zaidan has accomplished something I would not have thought possible. He has written an entertaining book about chemistry.  Thank you, George, for this much-needed breakwater against the tide of misinformation that sloshes onto our screens.” —Mary Roach, author of Stiff

Zaidan, an MIT-trained chemist who cohosted CNBC’s hit Make Me a Millionaire Inventor and wrote and voiced several TED-Ed viral videos, makes chemistry more fun than Hogwarts as he reveals exactly what science can (and can’t) tell us about the packaged ingredients sold to us every day. Sugar, spinach, formaldehyde, cyanide, the ingredients of life and death, and how we know if something is good or bad for us—as well as the genius of aphids and their butts—are all discussed in exquisite detail at breakneck speed.
