Considerations
Oil Overview
- The best cooking oil has a high smoke point, does not break down when heated, contains healthy ingredients, lacks unhealthy ingredients and has an appropriate flavor.
- All oils are fats (NOT all fats are oils).
- All fat has 9-calories per gram. This is true of all oils, too.
- There are three basic categories of fat (based on their fatty acid content) -- Monounsaturated, Polyunsaturated and Saturated.
Health Factors
- In general, healthy oils tend to break down into unhealthy chemicals when heated.
- Unless heated, the healthiest fat is Monounsaturated fat. It raises the good HDL cholesterol ratio.
- When heated, Monounsaturated fat tends to break down and become unhealthy.
- The unhealthiest fat is Saturated fat. It is associated with the bad, artery-clogging LDL cholesterol, but it is also the most stable when heated.
- Trans fatty acids are twice as unhealthy as saturated fats.
- Trans fatty acids are in hydrogenated and partially-hydrogenated oils. Avoid them.
- Linolenic (Omega-3) and Linoleic (Omega-6) are essential fatty acids. They are healthy (especially Omega-3), but they break down and become unhealthy when heated.
- Western countries typically consume too much Omega-6 and not enough Omega-3. They must be balanced.
Shelf Life
- Oils have a relatively short shelf life and become rancid rather quickly. Rancid fats have been associated with atherosclerosis, heart disease and cancer.
- Shelf life for cooking oils is about 3-months to 1-year. Exposure to oxygen, heat and light diminish an oil's shelf life.
- Refined oils stay fresh longer and can be heated to higher temperatures, but they contain more impurities than unrefined oils.
- Saturated fat has the longest shelf life, but it is the most unhealthy fat.
- Polyunsaturated fat readily combines with oxygen in the air to become rancid.
- Dark cooking oils have shorter shelf lives than light-colored or clear oils.
- Anti-oxidants extend an oil's shelf life.

Food manufacturers have until Jan. 1, 2006, to list trans fat on the nutrition label.
"On July 9, 2003, FDA issued a regulation requiring manufacturers to list trans fatty acids, or trans fat, on the Nutrition Facts panel of foods and some dietary supplements.
With this rule, consumers have more information to make healthier food choices that could lower their consumption of trans fat as part of a heart-healthy diet.
Scientific reports have confirmed the relationship between trans fat and an increased risk of coronary heart disease."
