Unsaturated fatty acids cause higher levels of LDL than saturated fatty acids.

Plant oils contain extremely low quantities of cholesterol.

Plant oils are healthier because they generally contain more unsaturated fats than found in animal fats.

Heart disease is associated with diets high in saturated fatty acids.

Saturated fats decrease the ratio of HDL to LDL in the blood.
