The product disrupted hormonal and water balance, causing edema to form throughout the body of the animals, reported by the Russian business consultancy, which brought studies from Bashkiria State University.
“Meat obtained from animals fed with Paprin contained an accumulation of abnormal amino acids that were incorporated into the membranes of nerve cells, thus disrupting the process of conducting a normal nerve impulse,” said Raisa Bashirova, principal investigator at Bashkiria State University, who added that it was even harmful to humans to paintings with Paprin:
“Factory staff and local citizens were presenting diseases such as canker sores and bronchial asthma. “ In the 1990s, almost the entire production of bioprotein in Russia was stopped. Gaprin, although it had proved to be safe and efficient, could not compete with rather cheap imported protein feedstuffs, which began to land on the local market in large quantities. Now, several decades later, bioprotein production in Russia seems to be getting a second chance.

(But going that route would waste a lot of energy.)
I didn't say that's what you should do or that it makes sense.
Merely as an illustration that you can start with some toxic substances and feed them to plants, and be very happy eating those plants.
Of course, that doesn't apply to everything. Heavy metals stay bad for you.
Believe me or not, I ate that yeast grown on petroleum paraffin once.
At the time of extreme food scarcity in Russia, we had people eating animal feed produced from yeast grown on paraffin. It's called paprin in Russian.
So, knowing that most of petroleum hydrocarbons are toxic if ingested, the result may be more amendable than the source product.
