Product Overview
Green leaf lettuce is a widely consumed leafy vegetable valued for its tender texture, mild flavor, and versatility. It is an important commodity in fresh produce markets, commonly used in both retail and food service sectors. Green leaf lettuce is typically marketed fresh in whole heads or loose leaves and is a staple in salads and fresh preparations.
Key Characteristics
Green leaf lettuce forms loose, open heads with broad, ruffled leaves. The leaves are light to medium green with soft, delicate edges. Texture is tender and crisp, with a mild, slightly sweet flavor. Unlike head lettuce, it does not form a tight core. Green leaf lettuce is non-climacteric and does not continue to develop after harvest.
Nutritional Value
Green leaf lettuce is low in calories and provides dietary fiber. It contains vitamin A, vitamin C, and vitamin K, along with small amounts of folate and potassium. Its high water content contributes to hydration and light dietary use.
Seasonality and Origin
Green leaf lettuce is grown in temperate climates and is available year-round due to continuous cultivation. Major production regions include the United States (California and Arizona), Europe, and parts of Asia. Its fast growth cycle ensures consistent supply in fresh markets.
