All Lettuce is not created the same. This crisp green vegetable is most often used in salads surrounded by an army of other vegetables, fruits, and sometimes nuts. Iceberg is the most commonly purchased variety of lettuce in the U.S., but how nutritious is it?
Iceberg Lettuce is a good source of fiber, zero fat, and very low in calories which makes it popular with dieters. However, it comes up short in the vitamin and nutrients department compared to its counterparts Romaine and Green Leaf lettuce, specifically Vitamin A, C, and Beta Carotene.
*One cup of shredded Iceberg contains 361 IU’s (International Units) of Vitamin A. Think that’s a lot? One cup of Romaine has 2729 IU’s, and Green Leaf has 2666 IU’s. Okay, let’s look at Beta Carotene, (based on one cup shredded), Iceberg; 215mcg, (micrograms), Romaine; 1637mcg, and Green Leaf 1599mcg. Vitamin C: Iceberg 2.0mg, (milligrams), Romaine 11.3mg, and Green Leaf 6.5mg.
The name Iceberg comes from the way the lettuce was transported in the US starting in the 1920s on train-wagons covered in crushed ice, making them look like icebergs.
*Another familiar lettuce I failed to mention, Butterhead (Bibb, or Boston), is also a good source of vitamins and nutrients boasting 1822 IU’s of Vitamin A, 1093mcg of Beta Carotene, and leads the other three in Potassium with 131mg per one cup shredded.
