Since butter and the predominant fatty acids of lard are saturated fats, they are already hydrogenated and resistant to oxidation. It is oxidation of polyunsaturated fats that produces harmful substances. Butter, consisting of short-chain fatty acids, has some other unique health benefits. These much-maligned fats should be thought of as condiments that, used in relatively small portions, can add zest to ordinary foods. Trans-fats, on the other hand, are foreign to our bodies and should not be eaten.
