In That's Disgusting, Rachel Herz discusses different types of disgusting things and why people find them disgusting in an entertaining and easily-readible manner. Her writing style is similiar to Mary Roach's, but without all the footnotes. This book has some psychology, some biology, and some social science. There is even a quiz included to reveal how easily disgusted you are. This an appealing book about some unappealing topics; highly recommended.
