I know we think that food corporations think more about themselves than they do about others when they decide to put partially hydrogenated oils and high fructose corn syrup in our foods.

Polyunsaturated fats, which are typically of vegetable origin, have the opposite effect; thus corn, safflower, soybean and sesame oils tend to lower the level of potentially dangerous LDL.

Corn oil is probably the least healthy of the oils mentioned, with more harmful saturated fats than canola or sunflower and fewer heart-healthy compounds than soybean.
