Canada's Food Guide, which has been in continual publication since 1942 and is the second most requested government document after the income tax form in Canada, recognizes only four official food groups, listing the remainder of foods as "another". Some of these "others" include: Alcoholic beverage or Alcohol is listed apart from other food groups and recommended only for certain people in moderation by Harvard's Healthy Eating Pyramid and the University of Michigan's Healing Foods Pyramid, while Italy's food pyramid includes a half-serving of wine and beer.
