What are oils? Oils are liquid fats. They give a rich flavor to foods they are found in, such as nuts, seeds, and fish. Brian P. Cleary’s goofy verse and Martin Goneau’s humorous illustrations give young readers a slick bunch of examples of oils and foods rich in healthy oils. They also highlight some health benefits of eating a limited amount of oil. Oils and oil-rich foods are printed in color for easy identification. Enjoy this flavorful serving of a book!
