Zucchini, The Origin Of The Plant
Courgettes are the fruit of the Cucurbita pepo species and belong to the Cucurbitaceae family together with:
Wild courgettes, from which the cultivated varieties we know today originated, can be traced back to the ancient indigenous peoples of the Americas: Aztecs, Mayas, and Incas. After the discovery of the Americas by Europeans in the 15th century, they were introduced to Europe and other parts of the world. As we know them today, the shape and color of courgettes result from selections and hybridizations that took place later. In particular, the dark green cylindrical zucchini, the most common variety, originated in Italy in the early 20th century.
The Peculiarity Of The Courgette
In addition to a good share of:
- and phosphorus
Zucchini provides a fair amount of vitamin C, equal to almost 30% of the daily requirement. They also provide numerous bioactive compounds, including:
- and cucurbitacin
The term “cucurbitacin” refers to an entire family of compounds the plant produces to defend against herbivorous animals. These molecules are triterpenes that give a very bitter taste to the fruit and thus deter consumption; if taken in high doses, these triterpenes can cause a syndrome characterized by nausea, vomiting, and diarrhea. However, following the long process of variety selection, today, the cucurbitacin content present in the courgettes that we find on the market is reduced to a minimal and completely harmless presence.

To get the most hydrating benefit from zucchini, eating them fresh and preferably raw is best, as cooking can reduce the water content.

How To Choose Zucchini
Opt for medium-sized or small zucchinis, which are more tender and flavorful than huge ones. More giant zucchinis may have firmer flesh and well-developed seeds. I prefer tight and compact courgettes with shiny and intact skin. A courgette with the flower still attached is a sign of a very fresh fruit characterized by an excellent consistency and a pleasant and aromatic flavor.
Zucchini can be eaten both cooked and raw; they are the undisputed protagonists of the first courses, side dishes, or second courses of the summer season. Let’s see together some recipes that have them as protagonists: Zucchini can be steamed, eaten boiled, or sautéed in a pan.
