There are several categories of a vegetarian diet, witheach category involving the exclusion of particularanimal products. A lacto-ovo vegetarian diet excludesmeat, fish, and poultry but permits the consumptionof dairy and eggs (Venderley & Campbell, 2006).This category can be further subdivided into lactovegetarians and ovo vegetarians, who exclude eggs ordairy respectively (Venderley & Campbell, 2006). Avegan diet excludes all animal products so that meat,poultry, fish, dairy products, eggs, gelatin, honey, andanimal-derived additives and colours are not consumed (Venderley & Campbell, 2006). A macrobiotic diet includes fish but excludes meat, poultry,eggs, and dairy products as well as some non-animalproducts such as tropical fruit, processed sweeteners,and vegetables belonging to the nightshade familysuch as tomatoes and potatoes (Venderley & Campbell, 2006). A fruitarian diet is a modified version ofthe vegan diet and is primarily based on theconsumption of raw or dried fruit, thus making itthe least common of all vegetarian diets (Venderley &Campbell, 2006).
