The Global Favorite: History of Green Beans

Green beans (Phaseolus vulgaris), also known as string beans or snap beans, originated in Central and South America over 7,000 years ago. Spanish and Portuguese explorers introduced them to Europe in the 16th century, where they quickly became popular for their tender pods and nutritional value.

Unlike other beans consumed only when dried, green beans were valued for their edible pods. Early varieties had tough "strings" running along the seams, leading to the name "string beans." Modern cultivars have been bred to eliminate these strings while maintaining their crisp texture.

Today, green beans are grown worldwide and appreciated in many cuisines. They're available year-round, either fresh, frozen, or canned, making them one of the most accessible and versatile vegetables in global markets.
