When it comes time to whip up your favorite meal, one of the first items you'll grab is probably some form of vegetable oil or animal fat — like a jug of canola oil or a tub of butter. But have you ever stopped to think about what option is the healthiest way to kickstart a recipe? The choices may seem overwhelming, and now, many consumers are embroiled in a hot debate over growing suspicion of seed oils.

What to believe, then? See the full picture of seed oils and how they compare to animal fats in terms of human health.
