From a strictly botanical point of view, green beans are nothing more than unripened beans. Therefore still grown unripe, with the seeds unformed. However, this particularity gives them very different nutritional and organoleptic properties from mature legumes. The bean appears to be poorer in calories and with a drastically less significant supply of proteins and carbohydrates; on the other hand, there is a different vitamin contribution and a higher concentration of some mineral salts. It should be noted that for the marketing of beans on a large scale, some varieties of dwarf and climbing beans are selected, since they are the ones that provide the green pods with the sweetest, most harmonious and least pungent taste.
