Forgot about this: there are upland varieties of rice.
Do bean sprouts have enough vit. C?
Good for you, maybe, but not a good bet for a new population. Peanuts are one of those most common allergies, and among the most likely to be fatal.
I was always taught this growing up, and also that they should be planted along with the leftovers from cleaning fish. But no one could ever tell me what type of beans were meant. Is it green beans? Garbanzos? Kidney?
Phaseolus vulgaris—includes green beans and kidney beans, navy, pinto, great northern, snap, black turtle, etc., besides other Phaseolus spp. like lima beans P. lunatus—all native to the Americas. But garbanzo is Cicer, an Old World genus.
We don’t have a lot of details on the hypothetical - if it is really and truly a “new earth” with a globe just like ours, then obviously staples will vary from place to place just as they do now, based on different climactic conditions if nothing else.
Anyway, staples for Pacific Islanders should be fish, coconut, and sweet potatoes (eating both tubers and leaves). Which is not far from the actual case on our current earth in some places, though taro is more popular than sweet potatoes and imported Spam, rice, and turkey tails have overtaken much of the locally available food.
