Which lettuce variety is cited as the least nutrient-dense option available?

Answer

Iceberg lettuce

Iceberg lettuce is specifically identified as the variety often cited as having the least nutrient density among the common options. While it possesses the benefits of being low in calories and very hydrating due to its composition primarily of water, its contribution of essential micronutrients like vitamins and minerals is described as minimal when compared against darker, crisper varieties such as Romaine or Red Leaf. The text emphasizes that the nutritional payoff for Iceberg is significantly lower than for varieties with deeper leaf coloration.
