Green beans are a type of legume in the Fabaceae family, cultivated for over 5,000 years in various regions of the world, especially in temperate climates. Known for their Perona variety, these beans are flattened and stringless, making them perfect for cooking. Nutrients such as vitamins A, C, and B, along with minerals like potassium and calcium, make them essential food, particularly for children, due to their folate content that supports healthy growth and development. These beans, which contain 90% water, are low in calories, making them ideal for diets. They are recommended for various conditions like gout and cholesterol issues. Their versatility in cooking allows them to be prepared in many ways: boiled, grilled, or in salads. They should be well-chosen, looking for bright and smooth specimens, and are best stored in the fridge in perforated plastic bags to maintain freshness. Their use has transcended cultures, from their discovery in America to their current consumption across Europe.
