The 100-Mile Diet: A Year of Local Eating (or Plenty: One Man, One Woman, and a Raucous Year of Eating Locally) is a non-fiction book written by Canadian writers Alisa Smith and J.B. MacKinnon. In the book, the authors recount their experiences, including motivations and challenges, on restricting their diet, for one year, to include only foods grown within 100 miles of their residence. Beginning in March 2005, with little preparation the urban couple began only purchasing foods with ingredients they knew were all from within 100 miles. Finding little in grocery stores, they relied on farmers' markets and visits to local farms. Staples in their diet included seafood, chicken, root vegetable, berries, and corn. They lacked cooking oils, rice, and sugar. They preserved foods for use in the winter but ended with extra supplies.
