One cup of iceberg lettuce contains: 10 calories, 0 grams of fat, 1 gram protein, 2 grams carbs (1 of dietary fiber), 7 percent of vitamin A, 3 percent of vitamin C, 1 percent of calcium and 2 percent of iron. It also contains trace amounts of potassium, folate, vitamin K, magnesium and phosphorus.
Subsequently, one may also ask, what is the healthiest type of lettuce?
The more greens you eat, the healthier you'll be. The Bottom Line: Leafy greens are great for you, and you should be eating more of them! Skip the iceberg and other light-colored lettuces and instead load up on kale, spinach, romaine, arugula, and other dark greens.
Is romaine or iceberg lettuce better?
film To say that one kind of lettuce is "healthier" is pointless as long as you do not know where it has been grown, how and if it was fertilized and whether it was rinsed properly before serving. Romaine lettuce indeed has a higher nutritional value than iceberg, but still has barely any nutritional value at all.
