Lettuce (Leaf, Green) is a vegetable whose variety, edible portion, and raw or cooked state affect its composition. It provides potassium and vitamin C. Choose produce without rot or major bruising. Refrigerate perishable items at 40°F/4°C or below and rinse under running water just before preparation—without soap.

Interesting fact
Washing reduces surface contamination but does not sterilize produce
Rinse under running water just before preparation, rub firm produce, and dry with a clean towel. Soap and household detergent are not recommended because produce is porous and residues can remain.
