trans fatty acids are produced?
Margarine and butter fatsNo, because most margarines contain hydrogenated or partially hydrogenated oils that produce trans-fats, which are just as bad -- or worse!! -- than naturally occurring saturated fat, as found in butter.There are some margarines that have little or no hydrogenated oils in the them. Some of the producers claim their spreads improve blood cholesterol ratios.
polyunsaturated fat
Man made fats, which include trans fats and partially hydrogenated oils are clearly the most dangerous. Polyunsaturated vegetable oils (Canola, corn, cottonseed etc), are already oxidized trans fats after the manufacturing process.
Shortening is made from partially-hydrogenated or hydrogenated vegetable oils.
The healthiest oils are oils that have polyunsaturated and monounsaturated fats. The healthiest oils are oils packed with saturated fats.
yes
Hydrogenated oils
Mono-diglycerides is another name for hydrogenated oils. The mono means they are a combination of various oils mixed, hydrogenated, then diglycerides are then separated out.
Nut oils like peanut oil. Safflower oil, corn oil, soybean oil, sunflower oil, and sesame oils are all good sources of polyunsaturated fats. Of course, olive oil is. Fish oils are also a good source.
Typically your polyunsaturated oils (corn) go rancid fast than more monounsaturated oils (olive), because polyunsaturated oils are more unstable. Saturated oils, though they have a reputation of being bad for you, are the most stable oils and, therefore, they keep much better. They also tend to have higher cooking temps.
