![]() For example, dark leaf lettuces tend to have more essential nutrients like vitamins A and K. Romaine lettuce provides over 17 times the Vitamin A and beta Carotene found in iceberg, nearly 5 times as much Folate, over 4 times as much Vitamin K and Selenium, and 2.4 times as much Iron. Iceberg lettuce, while not devoid of nutrients, generally has fewer vitamins and minerals than other lettuce varieties. We often read about how little nutrition is found in iceberg lettuce, but is this really true Well, compared with Romaine, the answer is a definite Yes. Lastly, there are nutritional differences. On the other hand, other lettuce types may exhibit a slightly bitter, peppery, or earthy taste that contributes more to the overall flavor of a dish. In contrast, typical “regular lettuce” might include varieties like green leaf or red leaf lettuce, which have loose, softer leaves and a more delicate texture.įlavor-wise, Iceberg lettuce has a subtle, almost neutral taste, allowing it to blend seamlessly in various dishes. Iceberg lettuce, with its tight head and crisp leaves, is known for its water content and refreshing crunch. However, we’ll look at some general distinctions. Hence, making a comparison between Iceberg and any particular “regular lettuce” might be too broad. In addition, it provides 10 more carbohydrates and 35 more calories which may help when trying to bulk up. It provides 133 more protein per 100 grams. It provides 2.86 grams of protein and romaine 1.23 grams per 100 grams. ![]() Therefore, romaine type lettuces with red rather than green leaves may offer a better nutritional choice.First of all, it’s crucial to understand that “regular lettuce” often refers to any type of green leafy vegetable in the lettuce family. Spinach is better than romaine for bodybuilding due to its higher percentage of protein and carbohydrates. Based on our study results, romaine was generally higher in nutrients analyzed, especially red romaine contained significantly higher amount of total carotenoids, total anthocyanins and phenolics. ![]() For leaf color comparison, red cultivars provided higher amount of minerals (Ca, P, Mn and K), total carotenoids, total anthocyanins and phenolics than green cultivars. Some of the most nutritious greens include spinach, kale, romaine, watercress, and arugula (see 'Salad greens by the numbers'). The content of Beta-carotene and lutein in romaine (668.3 ug g -1 dry weight) was ~45% higher than in crisphead (457.3 ug g -1dry weight). Iron and bone health-promoting minerals (Ca, Mg and Mn) were significantly higher ( P ≤ 0.001) in romaine. Alpha-linolenic acid (omega-3 polyunsaturated fatty acid) was the predominant fatty acid and was higher in romaine than crisphead. Go with the general rule of nutrition which says that dark red and green coloured veggies are more healthier and nutri-bound. In the investigated lettuce cultivars, insoluble fiber content was higher ( P ≤ 0.05) in romaine than crisphead lettuces. In our study nutritional composition was evaluated in the two most popular lettuce types in Western diets, romaine and crisphead ‘Iceberg’, with red or green leaves grown under uniform cultivating conditions and harvested at the same developmental stage. Studies of such parameters on the nutritional value have not been conclusive because the lettuce samples were collected from heterogeneous growing conditions and/or various developmental stages. It holds up well in storage and can be less expensive. Romaine lettuce has a higher nutritional value than iceberg lettuce, with more vitamins A. However, lettuce contains health-promoting nutrients and biosynthesis of such phytochemicals varies depending on cultivar, leaf color and growing conditions. Often thought to be lacking in nutrient content, iceberg is a good source of vitamin K and has folate. Romaine lettuce and iceberg lettuce are both popular types of lettuce. Lettuce ( Lactuca sativa L.) is one of the most popular vegetables worldwide, but is often viewed as low in nutritional value. According to the study, romaine lettuce contained the highest quantities of vitamin C, potassium, folic acid and lutein, while green leaf ranked the highest in vitamin K, niacin and riboflavin.
