Does iceberg lettuce have any nutritional value? Many people assume there are no good values derived from it but the fact is that just one serving contains nearly 1/4 of your daily value for vitamin K (which is important for bones).Aside from that, the health benefits are trivial. Single digits (less than 10%) of your daily value per serving for all of the following nutrients: vitamin A, vitamin C, vitamin E, thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, calcium, iron, magnesium, phospherus, potassium, zinc, manganese, selenium.Does iceberg lettuce have antioxidants? Yes, some. The number reflected above is quite low for a lettuce or leafy green, however it's still more antioxidant content than almost any meat or meat product. If at all possible, for your salad and sandwiches, try and choose something else. Even when it comes to iceberg lettuce vs., romaine, the ORAC value of romaine is over twice the amount. Ideally though, go for those darker in color such as red leaf, green leaf, butterhead, or a cruciferous like kale.
