Las verduras son hortalizas cuyo color predominante es el verde. Sin embargo, el uso popular suele extender su significado a otras partes comestibles de las plantas, como hojas, inflorescencias y tallos. El vocablo verdura no es de carácter científico ni botánico, tratándose de una denominación popular con un significado que varía de una cultura a otra, pudiendo en ocasiones ser sinónimo de hortalizas o equivalente a vegetales que no lleven el sabor dulce o ácido de las frutas (de allí que se hable de frutas y verduras). Las verduras son imprescindibles para nuestra salud.Igual que las frutas, sus vitaminas, antioxidantes, nos protegen de enfermedades. Las verduras son una parte importante de todas las estrategias saludables para adelgazar (regímenes, dietas, etc.). Las verduras constituyen también uno de los elementos más característicos de la dieta mediterránea. Su principal aporte son las vitaminas, minerales y la fibra. No tienen apenas proteínas ni lípidos pero sí cierta cantidad de hidratos de carbono. Son la principal fuente de vitamina A y C. La vitamina A va ligada al color amarillo o rojo, y la vitamina C al verde de las hojas.

In everyday usage, a vegetable is any part of a plant that is consumed by humans as food as part of a savory meal. The term vegetable is somewhat arbitrary, and largely defined through culinary and cultural tradition. It normally excludes other food derived from plants such as fruits, nuts and cereal grains, but includes seeds such as pulses. The original meaning of the word vegetable, still used in biology, was to describe all types of plant, as in the terms "vegetable kingdom" and "vegetable matter". Originally, vegetables were collected from the wild by hunter-gatherers and entered cultivation in several parts of the world, probably during the period 10,000 BC to 7,000 BC, when a new agricultural way of life developed. At first, plants which grew locally would have been cultivated, but as time went on, trade brought exotic crops from elsewhere to add to domestic types. Nowadays, most vegetables are grown all over the world as climate permits, and crops may be cultivated in protected environments in less suitable locations. China is the largest producer of vegetables, and global trade in agricultural products allows consumers to purchase vegetables grown in faraway countries. The scale of production varies from subsistence farmers supplying the needs of their family for food, to agribusinesses with vast acreages of single-product crops. Depending on the type of vegetable concerned, harvesting the crop is followed by grading, storing, processing and marketing. Vegetables can be eaten either raw or cooked and play an important role in human nutrition, being mostly low in fat and carbohydrates, but high in vitamins, minerals and fiber. Many nutritionists encourage people to consume plenty of fruit and vegetables, five or more portions a day often being recommended.
