Description of the coral beans
Coral beans, despite the name, are not beans but a variety of green beans . Beans and green beans belong to the same plant ( Phaseolus vulgaris ). The string bean, therefore, is nothing more than the immature harvested bean, when the pod is very thick and the seeds are absent or barely appeared.
They are legumes in all respects but atypical, because the edible part is not the seed, just mentioned, but the pod . This particular brings them closer to vegetables, both in general consideration (everyone considers them a vegetable), and in nutritional aspects (they are low-calorie ), and for the effects on digestion. Unlike beans and other legumes, green beans do not cause intestinal swelling and are much more digestible .
Green bean pods are generally green in color, but there are also yellow and violet. The taste remains more or less the same. Of turgid consistency and elongated shape, straight or curved, they have an intense color, green, yellow or violet depending on the variety.
