Essential Fatty Acids - Omega 3 and Omega 6

Omega 3 & Omega 6:

-we normally get enough Omega 6 in our diets but we are deficient in Omega 3 because of trans fatty oils and refined carbohydrates.

Omega 3 deficiency begins in utero, because mothers are deficient in Omega 3, especially DHA (docosahexenoic acid), usually in breastmilk. DHA is also absent in baby formulas in U.S. and Canada.

Research is proving that DHA deficiency is causing the epidemic of ADD in kids and adults. Learning ability and moods stabilize when supplemented with Omega 3. It is also a big role in the nervous system and brain function.

It also increases the production of series 1&3 ercosanoids and limits the production of series 2 pro-inflammatory ercosanoids.

That is why supplementing with Omega 3 helps arthritis, PMS, eczema, acne, diabetes, brittle nails, thinning hair, psoriasis, dry skin and sex hormones.

Nerve fibers in your body are coated with a fatty substance called the myelin sheath. If this coating gets thin or deteriates (MS) then your messages to your brain…as in sensory nerves,or from your brain….as in motor nerves, do not work properly. Your body needs the right components to do it’s job.

You need high quality Omega 3 & Omega 6 fats daily.

Good sources of Omega 3
-pumpkin seed, sunflower seed, flax seed or oil, canola oil and cold water fish

Good sources of Omega 6
-raw nuts, seeds, legumes, unsaturated vegetable oils such as borage oil, grape seed oils, primrose oil, and soyabean oil


To be beneficial these oils must not be heated, as they produce free radicals.

The daily requirement of essential fatty acids should not be more than 20 % of our total calorie intake.

Omega 3 and Omega 6 need to be in the right balance as in our Optomega. Excess Omega 6 can lead to overproduction of pro-inflammatory eicosanoids- limit their use.

TransFats:
-hydrogenated fats are margarine and shortening
-made by blowing hydrogen into liquid vegetable oil at very high temperatures /pressures
-contribute to overproduction of pro-inflammatory ecosanoids-contributing to cancer and heart disease
-trans fats are added to almost every type of packaged baked good as it doesn’t get rancid as quickly

Saturated Fats:
Not the culprit we’ve made it out to be!
-before 1940 lard and butter were widely used and heart disease and high cholesterol were rare. -a low glycemic diet keeps blood sugar and insulin levels in moderation (potatoes 98, ripe bananas 62, beets 64, raisons 64, puffed rice 95, cornflakes 80, white rice 88, white bread 72, glucose 100, fructose 20,)
-high glycemic spikes your insulin causing burnout and if your body doesn’t produce enough insulin-need to take it (diabetic)
-if your diet keeps insulin and blood sugar levels normal-then saturated fat is not likely to be much of a problem
-if you keep your carbohydrate level low then fat in your diet is not stored as fat.
-as soon as you combine saturates fats with sugar or starch (donut) then the pounds pack on as fat.

Genetically altered foods:
1992-U.S. FDA recognized GE foods as comparable to traditional food.
-labels are only required if an allergen is introduced
Since 1992-1/2 of all soy crops have been GE to produce a toxin to kill pests.
In the U.S. and Canada, most GE products are not labelled.

Dr Wentz took the Canola oil out of Optomega as he couldn’t find a good source that was not genetically engineered.

Australia is the second largest exporter of canola and they have been dumping tons of GE canola not approved for public consumption
