What's the verdict on soybean oil? I've read to avoid soy in general, but I don't know if that applies to soybean oil. I know it's an ingredient in Science Diet (which doesn't give me much confidence, but they claim it produces a shiny coat). The reason I ask if because I bought some sardines but mistakenly bought the ones that are in soybean oil instead of water or olive oil. Should I toss them or would it be ok this one time to feed em as a treat?
