Vegetarian Diet
Most vegetarians choose a lacto-ovo approach, turning their backs on meat, fish, and poultry while still eating dairy products and eggs. There are no restrictions on alcohol - if you want to have a drink or two a day, that's fine. The approach is significantly more alcohol-friendly than veganism, which only permits certain types of alcohol. Some wines, for example, are filtered through gelatin, egg whites, and isinglass, which is made from fish bladders, and vegans don't consume any animal products.
