Comparing Omega 3 From Flax, Seal and Fish Oil
Omega-3 and Omega-6 essential fatty acids are necessary for proper human growth and development throughout all stages of life. Both are found in equal amounts in our bodies when we are born, however as we age they deplete. Since the human body cannot make its own Omega-3 and 6, your diet must provide a steady intake of both.
Dietary Sources of Omega-3 ·flax / walnuts ·oily fish ·seal
Dietary Sources of Omega-6 ·plants and vegetables (especially in cooking oils)
Omega-3 and Omega-6 should be found in a 1:1 ratio. However our diets are so high in Omega-6 that many doctors suggest the Omega-3:Omega-6 ratio may be anywhere from 1:20 to 1:40.
If you are looking to increase your Omega-3 intake to try to balance the Omega-3:Omega-6 ratio, below is an explanation of the three types of Omega-3 supplements available to you.
Flax Oil
Flax oil is a non-marine source of Omega-3 and contains the Omega-3 called alpha-linolenic acid (ALA), which the body needs and cannot make for itself. Several other sources of ALA do exist, most notably walnuts and hemp seed. However, because flax only yields ALA, which then must be converted into EPA and DHA by the body, it is not an effective source of Omega-3 for the following reasons:
·Converting ALA into EPA and DHA is not very efficient, especially as one gets older ·Bodily conversion of ALA results in low levels of EPA and DHA ·Flax oil contains no DPA, the third main component of Omega-3 ·Flax oil is high in Omega-6, something our bodies do not need
The estimated rate of ALA to EPA and DHA conversion ranges from 5% to 25%. This means in order to make sufficient amounts of EPA and DHA, one would need to consume 5 to 6 times more ALA than you would if you were to use fish oil alone.
Fish Oil
Whether you are eating fish or taking fish oil supplements, fish has been known to contain numerous health benefits, especially fatty species which are rich sources of Omega-3 fatty acids. Proven benefits range from lowering triglycerides and blood pressure and the risk of heart disease, to the more subtle effects of reducing chronic inflammation. Fish oils provide a direct source of EPA and DHA. There are, however, some problems with fish oils:
High in Omega-6 ·Low levels of DPA ·Fish are susceptible to chemical pollutants and dioxins in the water
Seal Oil
Seal oil is one of the best and most direct sources of EPA, DHA and DPA, the third component of Omega-3. While DPA is present in some fish and fish oils, the levels are much lower than seal oil, about 1/5. Seal is oil has been determined to be the best source of Omega-3 for the following reasons:
Seal oil contains the highest levels of DPA (up to 10 times more than fish oils) ·It is chemically similar to the Omega-3 found in our bodies ·Seals can filter out chemical impurities better than fish
Unlike both flax and fish oil, seal oil has only traces of omega 6, and may be one of the best Omega-3 supplants to reduce the imbalance of Omega3:Omega-6.

Getting the Good Fats in Your Diet
Besides the important fat soluble vitamins A, E and D, scientists now realize that there are other good fats that every one needs in their diets. These good fats are absolutely essential for buoyant, vibrant health and fitness. They are the healing fats.
Essential Fatty Acids
Certain fats are called “essential” because you must get them in your diet in order to stay alive. These and other fatty acids are even more important than just sustaining life. An optimum intake can make the difference between a so-so life and a great life.
Essential fatty acids (EFA’s) form the membranes surrounding your trillions of cells. They help keep enemies, such as bacteria, allergens and toxic chemicals, out of your body.
And they give your cells the discretionary power to recognize the good nutrients that you need, such as vitamins, minerals and phytonutrients, and to absorb them into your cells.
EFA’s are major players in regulating virtually all of your bodily functions.
They act like magnets attracting the oxygen necessary for you to make energy out of food. And if you’re short on essential fatty acids, your body can’t use the protein in your diet to build and maintain muscle and tissue. Protein is turned into fat.
Omega 6 and Omega 3 Oils
Omega 6 and omega 3 are the two major categories of good fatty acids.
Good quality omega 6 oils are found in high fiber foods, such as whole wheat, brown rice, whole soy and other grains, seeds, nuts and beans.
Although processed vegetable oils are Omega 6, the essential fatty acids have been either removed, destroyed or turned into trans fatty acids by the processing. These refined vegetable oils, therefore, are of no benefit.
Omega 3 oils, with the valuable preformed EPA and DHA, used to be in many foods, but have been bred or processed out. Besides being available for babies in mother’s breast milk, they are now only abundant in cold water fatty fish. Salmon is the richest source.
Studies show that the balance and quality of oils in our diets has changed dramatically over the past century. Because our modern commercial diet is high in processed vegetable oils, it appears that we’re getting way more of the Omega 6 fatty acids.
But this isn’t exactly the case. Most of the Omega 6 oils in our diet are depleted of good fatty acids and high in trans-fatty acids. A high trans-fatty acid intake increases your need for the good omega 6 essential fatty acids.
Getting the Good Fats
Omega 3 fatty acids are now being called the most exciting anti-aging, disease fighting, feel-good substances of the new decade. Quality sources can balance your hormones, help protect you from degenerative diseases and slow down your aging process.
What does this mean to you on a day-to-day basis?
The natural anti-inflammatory qualities of good fats help reduce swelling and the pain associated with migraines, injuries and arthritis (or any other “itis” for that matter).
With your cells working better, you’re less susceptible to flu, colds and other illnesses. And with balanced hormones, you’ll feel a lot better and have a more positive outlook.
To increase your “good” fatty acids from high quality omega 6 and omega 3 oils, focus on a diet rich in whole food high fiber carbohydrates of whole grains, beans, seeds, raw nuts, fresh vegetables and pure cold water fatty fish.
Use small quantities of organic butter and virgin olive oil for cooking, recipes and salads. And when you use animal products, whenever possible, buy organic, free-ranging.
Taking high quality fish oil capsules is a great safe, low calorie, low cost way to get your omega 3 with EPA and DHA nutrition. To learn more about the best, most effective omega 3 fish oil supplements, go to the fish oil web site.
