What kind of food is this?
At 11kcal per 100g, its nutrient numbers run generally lower than the average of the vegetables listed here.
That does not mean it has no nutrition — it simply contains a great deal of water. Seen another way, it lets you add moisture and eating volume without adding many calories.
You can divide the roles: komatsuna or kale when you want denser nutrition, lettuce when you want moisture and bulk.
"Low in nutrients" is not an insult
Lettuce's nutrition numbers are on the low side because it holds a lot of water. Seen another way, that means it can add bulk and moisture while adding almost no calories. It is used to bulk up meals for dogs on weight management who seem unsatisfied with their portions. When you want to add nutrients, another option is to choose nutrient-dense leafy greens like komatsuna or kale.

(Food energetics is a long-standing idea of supporting the body through everyday meals. Treat it as one extra hint alongside the nutrition numbers.)
