Iceberg Lettuce

IT’S ALWAYS BEEN:
An inexpensive way for restaurants to offer a salad with every meal

IT’S ALSO:
A source of vitamin K (one serving provides up to 20% of your daily needs), which helps your body build bones. In a study of women ages 38 to 74, researchers found that those who ate lettuce once or twice a day had a 45 percent lower risk of hip fracture than peers who ate lettuce one or fewer times per week.
