Concept
Veganism
Summary
Veganism is the practice of abstaining from the use of animal product—particularly in diet—and an associated philosophy that rejects the commodity status of animals. An individual who follows the diet or philosophy is known as a vegan.
Distinctions may be made between several categories of veganism. Dietary vegans, also known as "strict vegetarians", refrain from consuming meat, eggs, dairy products, and any other animal-derived substances. An ethical vegan is someone who not only excludes animal products from their diet but also tries to avoid using animals, animal products, and animal-tested products wherever practical. Another term is "environmental veganism", which refers to the avoidance of animal products on the premise that the industrial farming of animals is environmentally damaging and unsustainable. Further motivations for vegan diets include concerns about animal welfare.
Vegan diets tend to be higher in dietary fiber, magnesium, folic acid, vitamin C, vitamin E, iron, and phytochemicals, and lower in dietary energy, saturated fat, cholesterol, omega-3 fatty acid, vitamin D, calcium, zinc, and vitamin B12. As a result of the elimination of all animal products, a poorly-planned vegan diet can lead to particular nutritional deficiencies that counteract its beneficial effects and may cause serious health issues, some of which can only be prevented with fortified foods or dietary supplements. Vitamin B12 supplementation is important because its deficiency can cause blood disorders and potentially irreversible neurological damage; this danger is also one of the most common in poorly-planned non-vegan diets.
The word vegan was coined by Donald Watson and his later wife Dorothy Morgan in 1944. Interest in veganism increased significantly in the 2010s.
The term "vegetarian" has been in use since around 1839 to refer to what was previously described as a vegetable regimen or diet. Its origin is an irregular compound of vegetable and the suffix -arian (in the sense of "supporter, believer" as in humanitarian).

Fruitarianism
Fruitarianism (fruː'tɛəriənɪzəm) is a diet that consists primarily of consuming fruits and possibly nuts and seeds, but without any animal products. Fruitarian diets are subject to criticism and health concerns. Fruitarianism may be adopted for different reasons, including ethical, religious, environmental, cultural, economic, and presumed health benefits. A fruitarian diet may increase the risk of nutritional deficiencies, such as reduced intake of vitamin B12, calcium, iron, zinc, omega-3 or protein.
Gelatin
Gelatin or gelatine (from gelatus 'stiff' or 'frozen') is a translucent, colorless, flavorless food ingredient, commonly derived from collagen taken from animal body parts. It is brittle when dry and rubbery when moist. It may also be referred to as hydrolyzed collagen, collagen hydrolysate, gelatine hydrolysate, hydrolyzed gelatine, and collagen peptides after it has undergone hydrolysis. It is commonly used as a gelling agent in food, beverages, medications, drug or vitamin capsules, photographic films, papers, and cosmetics.
Meat
Meat is animal flesh that is eaten as food. Humans have hunted, farmed, and scavenged animals for meat since prehistoric times. The establishment of settlements in the Neolithic Revolution allowed the domestication of animals such as chickens, sheep, rabbits, pigs, and cattle. This eventually led to their use in meat production on an industrial scale in slaughterhouses. Meat is mainly composed of water, protein, and fat. It is edible raw but is normally eaten after it has been cooked and seasoned or processed in a variety of ways.
