Which Oils should you cook with? (I don't agree with Rachael Ray)

Rachael Ray uses EVOO for every cooking need.  She even has her own label of EVOO. You should NOT COOK with EVOO but still keep in your diet. 
 Despite using more olive oil in our diets, Americans continued to suffer from heart disease, obesity and additionally many different types of cancer.  The most frequently asked question I get is about cooking oils.  Which ones are the best for your health?  Which ones are the best for cooking?  Here’s a lesson about cooking oils so you can choose the right oil for the right purpose and improve your health.



Mainstream media portrays olive oil as the healthiest oil as can be seen by the abundance Rachael Ray’s uses it in all her recipes, this title does not extend to cooking. Olive oil is primarily a monounsaturated fat. This means that it has one double bond in its fatty acid structure making it easily damaged when heated.  An overabundance of oleic acid in olive oil creates an imbalance on the cellular level, which has been associated to an increased risk of breast cancer and heart disease.  Olive oil is a smart fat to include in your diet only in a non-heated form.

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 255 calories per tablespoon. 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 (chicken, avocados, eggs, nuts, cereals, most vegetable oils) and not enough Omega-3 (flax seed oil, salmon, cod liver oil, caviar, and walnuts, broccoli, spinach). They must be balanced.

What are refined oils?
Refined Oils are created from clean oilseed / oil cakes using solvent extraction to produce clear oil. Use for baking, sautéing, stir-fry, oven cooking; searing, browning, and deep-frying. These oils are used as medium cooking oils (225°F - 350°F), high cooking oils (350°F - 450°F), and deep-frying oils (greater than 450°F).If the oil you buy is bland and pale, you can be certain that it has been fully refined, bleached, and deodorized which are not really good things to do to your oil for the sake of your health.

What are unrefined oils?
Unrefined cooking oils: These oils are typically called salad oils and are used for salad dressings, marinades, and sauces or light cooking oils (light sautes and low heat baking). As a general rule, they should not be cooked at high temperatures. Use for light sautéing, low-heat baking, pressure cooking, sauces and salads. However, safflower oil is the one unrefined oil that can become hot enough to reach the temperature necessary for deep-frying. Unrefined oil contains a full range of bioactive components that not only have healthful benefits and provide full-bodied flavor. Unrefined oils are processed by cold-pressed and expeller-pressed methods. Unrefined oils carry with them the true bouquet of olives, corn, sesame seeds, peanuts, soybeans, safflower, or whatever plant was the oil's original home. Best for medium heat temperature range: 212°F – 320°F.

Best Cooking Oil:
Coconut oil is the choice for cooking because it is nearly a completely saturated fat, which means it is much less susceptible to damage when it is heated.  Don't be scared away by the negative view of 'saturated fat' portrayed by the media. Many studies have shown that a low-fat diet is not the answer for preventing heart disease, and some scientists are calling for new dietary guidelines that reflect this discovery. To really understand the benefits of saturated fat, I suggest you read Dr. Mary Enig and Sally Fallon's article "The Truth About Saturated Fat" to first dispel any lingering notions you may have that all saturated fats are dangerous.

Most commercial coconut oils are refined, bleached and deodorized (RBD) and contain chemicals used in processing.  The recommended brand in the United States is Fresh Shores. This virgin coconut oil is not only certified organic, but it also has no GMO ingredients, bleaching, deodorizing, refining or hydrogenation. Fresh Shores also uses fresh coconuts (not "copra" or dried coconuts like most oils) that come from a rural region of the Philippines untainted by urban pollution.

Worst Cooking Oils:
Polyunsaturated oils, which include vegetable oils like corn, soy, safflower and canola, are the worst oils to cook with because of the trans-fatty acids introduced during the hydrogenation process, which results in increased dangers of chronic diseases such as breast cancer and heart disease.  This includes margarine due to the fact that it is hydrogenated vegetable oil.

The Vitality Test: Good Day Sacramento Airs Live Stair Climb of Wells Fargo Center In Downtown Sacramento, Green Tea & Olive Oil for Health

As the volunteer Executive Committee Chair for the American Lung Association’s Fight For Air Climb, I got up yesterday morning at 2 am to get down to the Wells Fargo Center. I had no idea of who all would be there. I had no idea of exactly what we would be doing. All I knew is that Good Day Sacramento was doing a live story on the Fight For Air Climb that is coming up next month, March 24th. Along with a firefighter, a gym owner, and Julie Lautsch, Regional Director for the American Lung Association we met Julissa Ortiz of Good Day Sacramento to climb the 34 flights of stairs for the morning news program. I arrived at 4:30 am and once we all gathered we stretched and warmed up then off we went. Our firefighter raced to the top in 4 minutes and 55 seconds. The rest followed at 6 to 6 and a half minutes and I finished in under 7 minutes. We had been delayed several times so it wasn’t until after 7 am that we began our climb. By then I was getting cold and hungry. I am amazed I did as well as I did! I have to credit my nutritional supplements and my regular exercise routine for my success. Next month, on March 24th, I expect my time to be even faster since I will have had a full night’s sleep and some food to fuel my body.

Here are some clips so prove I really did this yesterday!

Joy and my daily habit: Green tea please!
Joy and I each drink about 4 cups of green tea every day we work together in Sacramento. We love that it tastes good, keeps us warm, and gets us through a tired morning or afternoon. Green tea has long been used for many remedies  More than a decade’s worth of research about green tea’s health benefits — particularly its potential to fight cancer and heart disease — has been more than intriguing, as have limited studies about green tea’s role in lowering cholesterol, burning fat, preventing diabetes and stroke, and staving off dementia. Another benefit of green tea is that the more you drink or take the more calories you burn without increasing your activity.One of my favorite supplements has green tea in a capsule so you can maximize your calorie burn and healthy living without drinking gallons of tea. The supplement provides a highly concentrated, proprietary extract of green tea catechins to help protect your body at the cellular level. Each capsule contains the catechin equivalent of SEVEN cups of green tea without the caffeine. Containing 97% polyphenol antioxidants, two-thirds of which are catechins, It is one of the most potent antioxidant products on the market-providing you with maximum protection for critical cell structures such as DNA.


Health Tip: The Greek Secret to Healthy Life…Olive Oil
Well, first off, looking at the per capita consumption of all fats and oils, Americans average 1.3 lbs of fat and oil a week – that’s on the order of 120% of the USDA recommended amounts – no wonder we have an obesity epidemic. Very little of the oil consumed is olive oil. We consume so little olive oil that it’s measured per year, at only ½ liter annually. The Greeks on the other hand, use ½ liter of olive oil per week, and on the Greek island of Crete, even more! The phytonutrients in olive oil help maintain a healthy cholesterol to keep heart disease at bay. Also, some olive oils are very high in antioxidants.
