I will never persecute you for digging soybean oil mayo, either. However, I feel it's only neighborly to warn you that soybean oil does sometimes do weird things to a person. It can affect a man's prostate, and, depending on which study you believe, the soy-beaners or the meat-eaters, it is said by some to have a subtle feminizing effect on men. B.O. was a big soy-beaner, and look at him...
Soybean has natural estrogen in it.
