* "Settel’s work is both engaging to read and chock-full of facts. . . . There are lots of enticing bits to hold children’s interest through the somewhat drier sections on what is transpiring as the chyme hits the road through the entrails; and before readers know it they have followed food from ingestion to elimination and are happily wiser than they were at the start. Bjo¨rkman’s colorful cartoon illustrations keep perfect time with Settel’s chirpy, informative text. . . . An informative romp in an unexpected playground!"

– School Library Journal, starred review

"A fascinating, fact-filled tour of the digestive system. . . . Settel remarkably manages to maintain the text’s rhyme structure without sacrificing scientific detail or vocabulary (later emphasized with a detailed glossary). She also doesn’t shy away from tackling the grosser aspects of digestion (diarrhea, vomiting, and farting all find their place). Björkman’s pen, ink, and watercolor scenes break up the text and counterbalance the book’s advanced content with exaggerated humor. A one-stop rhyming shop for all things digestion."

– Publishers Weekly

"There's plenty of attention to chemical interactions and anatomical detail in these poems for all that they are cast in iambic couplets. . . . Björkman's cartoons, all bright colors and loose, fluid lines, add a diversely hued cast of young folk exuberantly chowing down, throwing up, looking amazed or grossed out, and posing as models for labeled internal views. . . . What's not to love?"
