I am an interested reader and I also learned that a soy-based diet "showed carbon isotope values between -21 and -25".
I also learned that there was no dispute that the diet of pigs was altered temporarily due to supply issues during the pandemic:
"Prof McGlone conceded at hearing that the diet of some pigs was altered during the COVID-19 pandemic due to the fact that the supply chain slowed down, which resulted in certain pig farms increasing the amount of soy fed to their pigs as opposed to corn".
