edible plant or part of a plant, involved in cooking From Wikipedia, the free encyclopedia
Vegetables are parts of plants that are eaten by humans as food as part of a meal. This meaning is often used: it is applied to plants to mean all edible plant matter, including the flowers, fruits, stems, leaves, roots, and seeds.[1][2][3]
Carrots and potatoes are parts of the root of the plants, but since they are eaten by humans, they are vegetables. They are not in the same category as a fruit, nut, herb, spice, or grain. Tomatoes are often thought of as vegetables, but because they have seeds, they are, botanically, fruits. Vegetables are an important part of people's diet. Vegetables and fruits are sometimes called produce. Vegetables have vitamins A, B, C, D, minerals and carbohydrates.
The USDA Dietary Guidelines for Americans recommends eating five to nine servings of fruit and vegetables everyday. The total amount eaten varies depending on age and gender.[4]
The word vegetable was first recorded in English in the early 15th century. It comes from Old French.[5] It is gotten from Medieval Latin vegetabilis "growing, flourishing" (i.e. of a plant).[1]
The meaning of "vegetable" as a "plant grown for food" was not accepted until the 18th century.[6] The year 1955 saw the first use of the slang term "veggie".[1]
The word "vegetable" can also be used to mean plants in general, such as when people say "Animal, Vegetable, or Mineral."[7]
However, in an Asian context, 'vegetable' may mean any plant produce, apart from grain and nuts, that is eaten cooked, while only the fruits eaten raw are considered as 'fruits'. For example, an artichoke is thought to be a vegetable, while a melon has the features of a fruit.[8]
"Fruit" has a botanical meaning. Peaches, plums, and oranges are known as "fruits". Many plants commonly called "vegetables", such as eggplants, bell peppers, and tomatoes, are fruits in botany.[9] The question of is a tomato a fruit or a vegetable was asked in the United States Supreme Court in 1893. The court ruled that a tomato is, and thus taxed as, a vegetable. This was for the Tariff of 1883 on imported produce. But the court knew that a tomato is a fruit in botany.[10]
Before agriculture, humans were hunter-gatherers. They looked for fruit, nuts, stems, leaves, corms, and tubers, scavenged for dead animals and hunted living ones for food.[11] Growing crops in a forest clearing is thought to be the first example of agriculture. Useful types of plant were grown while unwanted plants were removed. Plant breeding through the selection of plant with wanted characteristics such as large fruit and fast growth soon started.[12]
It is likely that many people around the world started growing crops in the period 10,000 BC to 7,000 BC.[13] Subsistence agriculture was the earliest form of agriculture. It involves the growing of crops by people to produce enough food for their families. Anything left is used for exchange for other goods.[14]
Throughout history, the rich have been able to afford different kinds of food including meat, vegetables and fruit. But for poor people, the food they ate was very dull. It is usually made up of mainly some staple product made from rice, rye, barley, wheat, millet or maize. The addition of vegetable gave some variety to the diet.[15]

Vegetables are very important in human nutrition. Most vegetables are low in calories but are large and filling.[16] They are a source of dietary fiber, essential vitamins, minerals, and trace elements.
When people eat more vegetables, it reduces the incidence of cancer, stroke, cardiovascular disease, and other chronic ailments.[8][17][18] The amount of nutrients of each vegetable is different. Some have useful amounts of protein though and varying proportions of vitamins such as vitamin A, vitamin K, and vitamin B6, provitamins, minerals; and carbohydrates.[19]
Vegetables are commonly eaten raw. It may become contaminated when they are made by an infected food handler. Hygiene is important when handling foods to be eaten raw. These vegetables need to be properly cleaned, handled, and stored to stop contamination.[20]
Vegetables have been big part of what humans eat. Some vegetables are perennial crops but most are annual and biennial crops. Cultivation of vegetables follows a particular pattern.[21] The pattern is usually followed like this:
On a small garden, tools like the spade, fork, and hoe are used. On commercial farms, mechanical equipments are used. These include tractors, ploughs, harrows, transplanters, cultivators, irrigation equipment, and harvesters.[22]
When a vegetable has matured it is ready to be harvested for storage or sale. There should be little damage and bruising to the crop when harvesting. Before storage or sale, damaged goods should be removed and produce should be picked according to its quality, size, ripeness, and color.[23]
All vegetables have to be stored to make them available all year round. A large proportion of vegetables are lost after harvest during the storage period. The main causes of loss include spoilage caused by moisture, moulds, micro-organisms, and pests.[24]
Storage can be short-term or long-term. During storage, leafy vegetables lose moisture, and the vitamin C in them is lost quickly.
Cold storage is useful for vegetables like cauliflower, eggplant, lettuce, radish, spinach, potatoes, and tomatoes.[25] Storage of fruit and vegetables in controlled atmospheres with high levels of carbon dioxide or high oxygen levels can stop microorganisms from growing.[26]
The reason why vegetables are preserved is to make them available all year round. The goal is to harvest the food when it is mature with a high nutritional value, and preserve these qualities for a longer period of time. The main causes of spoilage during storage are the actions of naturally-occurring enzymes and micro-organisms.[27] There are many ways to preserve vegetables and they are:
In 2010, China was the largest vegetable producing nation, with over half the world's production. India, the United States, Turkey, Iran, and Egypt were the next largest producers. Here is a table with the needed information.[28]
