You'll find parrots, which have extremely high metabolic rates and long longevity, fare better off (live longer) by eating MORE seeds and grains, aka: more PUFA, but also more Vitamins found in the seeds. The net effect is actually less PUFA on mitochondrial membranes; these animals can use the compounds in seeds and grains specifically to exclude PUFAs from their mitochondria membranes, despite a high PUFA diet.
I doubt you will find high concentrations of PUFA in seeds of tropical plants. Their fat composition is highly dependant on the ambient temperature.
