The Lesser Yinglets were dependent almost entirely on mollusk meat, their bodies seemingly getting absolutely every vitamin and nutrient they need from this very specific type of meat.
The Greater Yinglets, however, have the stomach for just about anything. Yet despite this, mollusk-flesh seems to still contain a balance of nutrients that can nourish a yinglet almost perfectly as a foodstuff possibly can; or so we must surmise, from the comparatively intense reward the brain sends a yinglet who tosses any down its gullet…

On this page, it is said yinglets can eat just about anything. So then why did Kass make breakfast for Yinnit the first morning of being a scav? As for reward, sugar isn’t the best for many creatures but they love it like no other. So the body rewards itself for eating things that are not always good.
It used to be that we could only GET sugar from fruits packed full of useful vitamins. And also that it very efficiently turned into fat for the winter. Both of these things used to be super useful for our (and other species’) survival.
Evolution, unfortunately, doesn’t run fast enough to adjust to a world where stacks of pure sugar cubes can be bought cheaply from most any grocery store.
Reminds me of Epicurus and his bread, water, and occasional pot of cheese. https://youtu.be/E5f5smh7Keo?t=455
