Vegetables in a market in the
Philippines.
VegetableFrom Wikipedia, the free encyclopedia
In culinary terms, a vegetable is an edible plant or its part, intended
for cooking or eating raw.[1] In biological terms, "vegetable"designates members of the plant kingdom.
The non-biological definition of a vegetable is largely based onculinary and cultural tradition. Apart from vegetables, other maintypes of plant food are fruits, grains and nuts. Vegetables are mostoften consumed as salads or cooked in savory or salty dishes, whileculinary fruits are usually sweet and used for desserts, but it is not the
universal rule.[1] Therefore, the division is somewhat arbitrary, basedon cultural views. For example, some people consider mushrooms to
be vegetables even though they are not biologically plants,[2][3] while
others consider them a separate food category;[4] some cultures
group potatoes with cereal products such as noodles or rice,[5] whilemost English speakers would consider them vegetables.
Some vegetables can be consumed raw, while some, such as cassava,must be cooked to destroy certain natural toxins or microbes in orderto be edible. A number of processed food items available on themarket contain vegetable ingredients and can be referred to as"vegetable derived" products. These products may or may notmaintain the nutritional integrity of the vegetable used to producethem.

culinary sense and "fruits" in the
botanical sense
Etymology
The word vegetable was first recorded in English in the early 15th
century from Old French,[6] and was in origin applied to any plant.This is still the sense of the adjective "vegetable" in biological
context.[7] The word is taken from Medieval Latin vegetabilis"growing, flourishing" (i.e. of a plant), a semantic change from a LateLatin meaning "to be enlivening, quickening", a derivation of the verbvegetare "enliven", which is derived from vegetus "to be alive, active"(related to vigor), in reference to the process of a plant growing.
In 1767, the meaning of the term "vegetable" was specified to mean"plant cultivated for food, edible herb or root." The year 1955 noted
the first use of the shortened, slang term "veggie".[6] As an adjective,the word vegetable is used in scientific and technical contexts with a different and much broader meaning,namely of "related to plants" in general, edible or not — as in vegetable matter, vegetable kingdom,
vegetable origin, etc.[7] The meaning of "vegetable" as "plant grown for food" was not established until the 18th
century.[8]
Terminology
There are at least four definitions relating to fruits and
vegetables:[citation needed]
Fruit (botany): the ovary of a flowering plant (sometimesincluding accessory structures),
Fruit (culinary): any edible part of a plant with a sweet flavor,Vegetable (culinary): any edible part of a plant with a savoryflavor.
Vegetable (legal): commodities that are taxed as vegetables in aparticular jurisdiction
In everyday, grocery-store, culinary language, the words "fruit" and
"vegetable" are mutually exclusive[citation needed]; plant products thatare called fruit are hardly ever classified as vegetables, and vice-versa. The word "fruit" has a precise botanical meaning (a part thatdeveloped from the ovary of a flowering plant), which is considerably different from its culinary meaning, andincludes many poisonous fruits. While peaches, plums, and oranges are "fruit" in both senses, many itemscommonly called "vegetables" — such as eggplants, bell peppers, and tomatoes — are botanically fruits, whilethe cereals (grains) are both a fruit and a vegetable, as well as some spices like black pepper and chili peppers.The question of whether the tomato is a fruit or a vegetable found its way into the United States Supreme Courtin 1893. The court ruled unanimously in Nix v. Hedden that a tomato is correctly identified as, and thus taxedas, a vegetable, for the purposes of the Tariff of 1883 on imported produce. The court did acknowledge,
however, that, botanically speaking, a tomato is a fruit.[9]
Languages other than English often have categories that can be identified with the common English meanings of"fruit" and "vegetable", but their precise meaning often depends on local culinary traditions. For example, inBrazil the avocado is traditionally consumed with sugar as a dessert or in milkshakes, and hence it is regarded as

a culinary fruit; whereas in other countries (including Mexico and the United States) it is used in salads and dips,
and hence considered to be a vegetable.[citation needed]

Nutrition
Vegetables are eaten in a variety of ways, as part of main meals andas snacks. The nutritional content of vegetables varies considerably,
though generally they contain little protein or fat,[10][11] and varyingproportions of vitamins such as Vitamin A, Vitamin K and VitaminB6, provitamins, dietary minerals and carbohydrates. Vegetablescontain a great variety of other phytochemicals, some of which havebeen claimed to have antioxidant, antibacterial, antifungal, antiviral and
anticarcinogenic properties.[12][13] Some vegetables also containfiber, important for gastrointestinal function. Vegetables containimportant nutrients necessary for healthy hair and skin as well. Aperson who refrains from dairy and meat products, and eats onlyplants (including vegetables) is known as a vegan.
However, vegetables often also contain toxins and antinutrients such
as α-solanine, α-chaconine,[14] enzyme inhibitors (of cholinesterase,protease, amylase, etc.), cyanide and cyanide precursors, oxalic acid,
and more.[15] Depending on the concentration, such compounds mayreduce the edibility, nutritional value, and health benefits of dietaryvegetables. Cooking and/or other processing may be necessary toeliminate or reduce them.
Diets containing recommended amounts of fruits and vegetables mayhelp lower the risk of heart diseases and type 2 diabetes. These dietsmay also protect against some cancers and decrease bone loss. Thepotassium provided by both fruits and vegetables may help preventthe formation of kidney stones.
Dietary recommendations
The USDA Dietary Guidelines for Americans recommends consuming 3 to 5 servings of vegetables daily.[16]
This recommendation can vary based on age and gender, and is determined based upon standard portion sizes
typically consumed, as well as general nutritional content.[17] For most vegetables, one serving is equal to1/2 cup and can be eaten raw or cooked. For leafy greens, such as lettuce and spinach, a single serving istypically 1 cup. Serving sizes for vegetable-derived products have not been definitively determined, but usuallyfollow the 1/2 cup standard. Examples of vegetable-derived products subject to this standard are ketchup, pizzasauce, and tomato paste. Currently, there is no specific standard for measuring a vegetable serving in regards toits nutrient content, since different vegetables contain a wide variety of nutrients.
International dietary guidelines are similar to the ones established by the USDA. Japan, for example,
recommends the consumption of 5 to 6 servings of vegetables daily.[18] French dietary guidelines follow similar
guidelines and set the daily goal at 5 servings.[19]
Color pigments
The green color of leaf vegetables is due to the presence of the green pigment chlorophyll. Chlorophyll isaffected by the pH, and it changes to olive green in acid conditions, and to bright green in alkaline conditions.Some of the acids are released in steam during cooking, particularly if cooked without a cover.
The yellow/orange colors of fruits and vegetables are due to the presence of carotenoids, which are alsoaffected by normal cooking processes or changes in pH.
The red/blue coloring of some fruits and vegetables (e.g., blackberries and red cabbage) are due toanthocyanins, which are sensitive to changes in pH. When the pH is neutral, the pigments are purple, whenacidic, red, and when alkaline, blue. These pigments are quite water-soluble. This property can be used inrudimentary testing of pH.
Commercial cultivation
Method of vegetable production
Most vegetables are produced using traditional farming practices. However, the yield of vegetables from organicfarming is growing.
Origin countries
Of all the world's nations, China is the leading cultivator of vegetables, with top productions in potato, onions,cabbage, lettuce, tomatoes and broccoli.
Domestic cultivation
Amateur vegetable growing has a long history dating back to the establishment of agriculture and is a substantialbusiness in itself, with one major online UK seed supplier currently offering well over 1200 cultivars of seeds,plants and potato tubers. They report that sale of vegetable seeds now outstrips that of flower seeds.
Plants are usually divided into the following categories:-
Root vegetables (carrot, parsnip, beetroot, turnip)
Leafy green vegetables (cabbage, broccoli, Brussels sprout, kale, spinach, cauliflower)Alliums (onion, leek, garlic, shallot)
Potatoes
Legumes (peas and beans)
Pumpkin family (cucumber, courgette, marrow, squash, pumpkin, gourd)Tomatoes
Salad crops (lettuce, radish, rocket, celery, cress, bean sprouts)
Other vegetables (pepper, sweet potato, corn, artichoke, asparagus, mushroom)[20]

Each group has its own cultivation needs, but the overall requirements for the vast majority of vegetable plantsare:
deep, rich soil with a neutral or slightly alkaline compositionplenty of sunshine
plenty of water
regular feedingregular weeding
protection against pests such as slugs, aphids and
caterpillars[21]
The substantial literature and other media on the subject advise deepdigging, annual top dressing with manure or home-made compost,and crop rotation. Other issues are also discussed at length,including:-
raised beds
successional sowing
garden design
allotments[22]
raising plants for competition
comparative evaluation of different varieties
organic gardening
Increasingly, small plants (plug plants) are offered for sale in spring and summer.
Safety
For food safety, the CDC recommends proper fruit handling andpreparation to reduce the risk of food contamination and foodborneillness. Fresh fruits and vegetables should be carefully selected. At thestore, they should not be damaged or bruised and pre-cut piecesshould be refrigerated or surrounded by ice. All fruits and vegetablesshould be rinsed before eating. This recommendation also applies toproduce with rinds or skins that are not eaten. It should be done justbefore preparing or eating to avoid premature spoilage. Fruits andvegetables should be kept separate from raw foods like meat, poultry,and seafood, as well as any cooking utensils or surfaces that mayhave come into contact with them (e.g. cutting boards). Fruits andvegetables, if they are not going to be cooked, should be thrown
away if they have touched raw meat, poultry, seafood or eggs. All cut, peeled, or cooked fruits and vegetablesshould be refrigerated within 2 hours. After a certain time, harmful bacteria may grow on them and increase the
risk of foodborne illness.[23]
Storage
Proper post-harvest storage aimed at extending and ensuring shelf life is best effected by efficient cold chain
application. All vegetables benefit from proper post harvest care.[24]
"Vegetables"
Many root and non-root vegetables that grow underground can be stored through winter in a root cellar or othersimilarly cool, dark, and dry place to prevent the growth of mold, greening and sprouting. Care should be takenin understanding the properties and vulnerabilities of the particular roots to be stored. These vegetables can lastthrough to early spring and be nearly as nutritious as when fresh.
During storage, leafy vegetables lose moisture, and the vitamin C inthem degrades rapidly. They should be stored for as short a time aspossible in a cool place, in a sealed container or a plastic bag.
Standards
There is a series of ISO standards regarding fruits and vegetables.[25]
