Are the seeds of tree spinach edible?

Hi
I have a lot of tree spinach in my garden and I love it.
I know it's in the same family as amaranth and it sets a relatively large amount of seed. Can I eat those?
Maybe as quinoa/amaranth?
Thanks,

best,
Anna

Well Wikipedia thinks they are, take that for what it's worth. I am not aware of any close relatives that are poisonous so I personally would be happy to consume them.

Plants for a future say yes too:

Edible Uses:

Leaves - cooked[46, 61, 105, 177]. Of excellent quality, they are a spinach substitute[74]. The raw leaves should only be eaten in small quantities, see the notes above on toxicity. Seed - cooked. Ground into a powder and used with wheat or other cereals in making bread etc. The seed is small and fiddly, about 1.5mm in diameter[266], it should be soaked in water overnight and thoroughly rinsed before it is used in order to remove any saponins.
