Despite the trend for darker leaved lettuces, the iceberg, from the family of "crispheads" is still one of the most popular lettuces around the world. According to the Economic Research Service, USDA, Americans consume more iceberg lettuce than any other variety, at around 22 pounds per person per year.
California produces about 72 percent of all icebergs grown in the United States (followed by Arizona at 25 percent). Although slightly lacking in the nutrition department, the iceberg remains supreme. With a water content of 95%, nothing beats an iceberg lettuce for making a refreshingly crisp bed for a healthy salad on a hot summer day, or for adding the perfect crunch to a sandwich.
