A variety of vegetarian food ingredients
Vegetarianism is the practice of a diet that excludes all animal products from diet. By some strict definitions, animal products are not used for attire either, whether or not the production of clothing or items has involved the death of the animal, many vegetarians, especially vegans, do not wear or use wool. A common alternative for cold-weather wear is polar fleece, which has the added benefit of being available in versions that are made from recycled plastic.
