In clinical tests, soybean oil has been shown to cause birth defects and in rare cases, gigantism. So one of my friends started drinking gallons and gallons of it, as much as he could drink. He thought it would make him taller. To be fair he grew like half an inch taller but mostly what happened over the next few months is his arms and legs got really thick and really hairy. His legs looked like furry tree trunks. He weighs 350 pounds now, all muscle.
