Green Leaf Lettuce

Green leaf lettuce makes a nutrient-dense choice, and for those young eaters who may be a little picky, it also has a milder taste than other greens. Just 1 cup delivers fiber, iron, and B vitamins together with a boost of several other vitamins.

Green leaf lettuce contains vitamin A in the form of three carotenoids: beta-carotene, lutein, and zeaxanthin. One cup of shredded, green leaf lettuce has 88% of the recommended daily intake of vitamin A, 38% of the recommended daily intake of vitamin K, and 4 % of the recommended daily intake of vitamin C.
