What percentage of lettuce's total weight is typically water content?
Answer
94% to 95%
Lettuce is overwhelmingly composed of water, often making up 94% to 95% of its total weight. This high water composition is a primary reason why lettuce is naturally classified as a low-calorie and highly hydrating food choice. This characteristic directly supports its role in hydration maintenance and contributing to satiety without adding significant caloric load to the diet. The remaining percentage accounts for the dry mass, which includes vitamins, minerals, fiber, and bioactive compounds that deliver specific health benefits.
