Radicchio

Contents

It is a salad that belongs to the chicory family. In his “Natural History” Pliny the Elder wrote about this plant as a remedy capable of purifying the blood and helping people suffering from insomnia. Also Marco Polo wrote about radicchio. He claimed that it was a favorite product of the inhabitants of the Veneta region (present-day Venice). And today, radicchio is one of the most popular salads among Italians.

The technique of growing radicchio with bright purple leaves was invented by an agronomist from Belgium Francesco van den Borre. He came up with the idea of ​​getting young plants out of the ground and sending them to the basement, where, due to the lack of sun, the leaves turn pale, and with the onset of cold weather (radicchio loves low temperatures) they acquire a beautiful purple color. At the same time, a slight bitterness appears in the taste of the leaves.

Today, the leader in the cultivation of radicchio is the Italian province of Treviso. In this region, people have been holding annual fairs and folklore festivals for several centuries in the name of this vegetable.

Key types of radicchio

Several types of the popular radicchio salad are in the list below:

Radicchio
  • Radicchio di Castelfranco is a variegated plant from Castelfranco. This variety has light upper leaves with purple blotches. It ripens in November-December.
  • Radicchio from Treviso is an early maturing red variety from Treviso. This salad, which has long purple leaves, looks like a chicory salad.
  • Radicchio rosso tardivo is a late red variety from Treviso. This variety ripens no earlier than December and has a more bitter taste than early maturing radicchio. The leaves in the head of this variety are looser.
  • Radicchio from Chioggia is a year-round cultivar. This plant has a dense head of cabbage with purple leaves.

How to choose radicchio

In order to choose tasty radicchio, you need to look for a dense plant head with bright flowers, crisp and shiny leaves. If you notice signs of darkening on the salad, this may indicate that the radicchio has been stored for too long. It is better to refuse such a product.

Radicchio
  1. Vitamin B9 that it contains participates as a coenzyme in the metabolism of amino and nucleic acids. Folate deficiency leads to disruption of protein and nucleic acid synthesis, resulting in inhibition of cell division and growth, especially in rapidly proliferating tissues: intestinal epithelium, bone marrow, etc. Insufficient consumption of folates during pregnancy is one of the causes of malnutrition, prematurity, congenital child development, and deformities disorders. There has also been a strong association between homocysteine ​​and folate levels and the risk of cardiovascular disease.

Other useful elements

  1. Potassium is the main intracellular ion involved in the regulation of water, electrolyte, and acid balance, in the regulation of pressure, in the conduction of nerve impulses.
  2. Copper is found in enzymes that have redox activity and are involved in iron metabolism, stimulating the absorption of carbohydrates and proteins. This element also participates in the processes of providing tissues with oxygen. Copper deficiency is manifested by problems with the formation of the cardiovascular system and skeleton, the risk of developing connective tissue dysplasia.
