Yes. Different vegetables have nutrients that lettuce does not.
if you are a snail maybe lettuce is enough but if you have 2 feet..you might want to search for other nutrients in other vegetables...
ick hope so
This a joke, right? Lettuce really has no nutritional value.
Yes, not all veg has the same amount of vitamins etc. I don't think lettuce has as many properties as a lot of other veg
Yes and what kind of lettuce are you eating. Romain is good stuff but, iceberg has no value.
romaine lettuce is good, iceberg is a bowel irritant. NO this is not enough to survive on.
you may want to mix it up, yeah.
