I know this is rather specific, but...
Also, if there is something to it, is there a difference in the l-tryptophan content of underripe vs. ripe plantains?

Here's the nutritional report on plantains: http://ndb.nal.usda.gov/ndb/foods/show/2367?fg=&man=&lfacet=&count=&max=25&sort=&qlookup=plantain&offset=&format=Full&new=
So yes, 27mg tryptophan per plantain. That's about the amount in 1/6 of a small hamburger patty. Sounds like we've busted a myth here.
There is at least some non-mythic evidence that eating carbohydrates that are low in protein can help tryptophan cross the blood-brain barrier and contribute to neurotransmitter synthesis. So perhaps that's what people are thinking of.
