Random blue check spouts disinformation about "seed oils" on the internet. Same random blue check runs a company selling "safe" alternatives to seed oils. Yud spreads this huckster's disinformation further. In the process he reveals his autodidactically-obtained expertise in biology:
Are you eating animals, especially non-cows? Pigs and chickens inherit linoleic acid from their feed. (Cows reprocess it more.)
Yes, Yud, because that's how it works. People directly "inherit" organic molecules totally unmetabolized from the animals they eat.
I don't know why Yud is fat, but armchair sciencing probably isn't going to fix it.
