Lettuce calories and nutrition facts

100 grams of lettuce contains 17 calories, with 1.2 g of protein, 3.3 g of carbohydrate and 0.3 g of fat. It provides 2.1 g of fiber and 1.2 g of sugar per 100 g. Most of its calories come from carbohydrate.

Lettuce is close to structured water: a cup of shredded leaves is about 8 calories. Its role on a plate is volume, crunch and the feeling of a proper meal, not nutrition or energy. The dressing is the entire calorie story of most salads — a couple of tablespoons can outweigh everything green in the bowl several times over.
