Essential fatty acids, or EFAs, are fatty acids that cannot be constructed within an organism (generally all references are to humans) from other components by any known chemical pathways, and therefore must be obtained from the diet. [citation needed] The term refers to fatty acids involved in biological processes, and not those which may just play a role as fuel. As many of the compounds created from essential fatty acids can be taken directly in the diet, it is possible that the amounts required in the diet (if any) are overestimated. [citation needed] It is also possible they can be underestimated as organisms can still survive in non-ideal, malnourished conditions. [citation needed]There are two families of EFAs ?-3 (or omega-3 or n-3) and ?-6 (omega-6, n-6). Fats from each of these families are essential, as the body can convert one omega-3 to another omega-3, for example, but cannot create an omega-3 from omega-6 or saturated fats.[citation needed] They were originally designated as Vitamin F when they were discovered as essential nutrients in 1923. In 1930, work by Burr, Burr and Miller showed that they are better classified with the fats than with the vitamins.[1] In the body, essential fatty acids serve multiple functions. In each of these, the balance between dietary ?-3 and ?-6 strongly affects function. Fatty acids are straight chain hydrocarbons possessing a carboxyl (COOH) group at one end. The carbon next to the carboxylate is known as a, the next carbon ß, and so forth. Since biological fatty acids can be of different lengths, the last position is labelled as a "?", the last letter in the Greek alphabet. Since the physiological properties of unsaturated fatty acids largely depend on the position of the first unsaturation relative to the end position and not the carboxylate, the position is signified by (? minus n). For example, the term ?-3 signifies that the first double bond exists as the third carbon-carbon bond from the terminal CH3 end (?) of the carbon chain. The number of carbons and the number of double bonds is also listed. ?-3 184 (stearidonic acid) or 184 ?-3 or 184 n-3 indicates an 18-carbon chain with 4 double bonds, and with the first double bond in the third position from the CH3 end. Double bonds are cis and separated by a single methylene (CH2) group unless otherwise noted. So in free fatty acid form, the chemical structure of stearidonic acid is

2. Essential Fatty Acid - The Food For Your Heart
November 05, 2009
An essential fatty acid is one that our body does not manufacture, it has to be obtained from the food we eat. The best way of obtaining these fatty acids once, was by eating several meals of fish per week. Now however because of the contamination is our oceans and indeed in our fish, we can no longer afford to eat so much fish.
The two most potent Omega 3 fatty acids in fish and in fish oil are DHA and EPA fatty acids. An essential fatty acid is a form of polyunsaturated fats found in Omega 3. The fish obtain these fats through eating algae and plankton, the fish that contain the most of... (read more)

4. Learn More about Omega 3 Fatty Acids
November 01, 2009
Let’s face it, there has been a great deal of scientific debate concerning which omega 3 fatty acids are essential in the human diet. Years ago, researchers found that alpha-lipoic acid, which is found in vegetable oils, like flaxseed, could be converted within the body to Eicosapentaenoic acid and then to Docosahexaenoic acid, using an intermediary called Docosapentaenoic acid to elongate the chain.
To use the letters, ALA can be converted to EPA and then to DHA, through the use of DPA to make the chain of carbon bonds longer. This process is obviously inefficient.
In recent s... (read more)

5. Discover the Best Prenatal Omega 3
October 31, 2009
Did you know that prenatal omega 3 fatty acid intake should be higher than what is recommended for non-pregnant women? A woman’s needs are also higher when she is breast feeding. If her dietary needs for DHA are not met, she could experience a variety of health problems.
DHA or Docosahexaenoic acid is an omega-3 that is essential for normal brain development in the fetus and in the infant. It continues to be important throughout a person’s life. A lack of it throughout a person’s life could be one of the causes of Alzheimer’s. Research concerning that is currently ongoing.

7. Why Omega 3 Greens Are Not The Best Way To Get These Essential Fatty Acids
October 26, 2009
With so much attention in the press recently, it's hardly surprising that omega 3 greens are being asked about more. There is however a fundamental problem with getting the omega 3 benefits this way, and unless you are a vegetarian, you should look to the other sources I reveal here.
The problem with omega 3 greens is that they give you a type of fatty acid called ALA, which is far less useful than the two main ones, DHA and EPA. Despite what many would have you believe, it is rarely converted by the body into the useful ones and therefore while providing some benefits, you are not seeing... (read more)

9. Discover the Benefits of Omega-3 for Children
October 19, 2009
Let’s face it. A number of studies have revealed the benefits of omega 3 for children. It is because of those studies that DHA (Docosahexaenoic acid) is now found in many infant formulas. It has always been in human breast milk, but until recently, it was not believed to be essential for normal growth and development.
The essential nutrients are the ones that the body cannot create. They must be present in the diet. The body can use a different omega-3 called ALA (alpha-linolenic acid) to create DHA. So, again, until recently, ALA was the only fatty acid present in infant formulas. ... (read more)

10. How to Find the Correct Dosage of Fish Oil
October 19, 2009
At one time, parents gave their kids a dosage of fish oil to keep their digestive systems regular, protect against rickets and prevent vitamin A deficiency. Back then, no one knew about the benefits in brain development or the essential nature of omega-3 fatty acids and DHA, in particular.
Fish oils are rich in omega-3 fatty acids called DHA (Docosahexaenoic acid) and EPA (Eicosapentaenoic acid). Fatty fishes are actually the only dietary source of those polyunsaturated fatty acids. The fishes get theirs from marine algae or by eating smaller fishes.
A different omega-3 called ALA... (read more)

12. A Guide to Omega 3 DHA
October 19, 2009
Let’s face it. The omega 3 DHA or Docosahexaenoic acid is essential for normal brain development in infants, which is why you will see that most formulas are now DHA-fortified. Breast milk doesn’t have to be fortified, because it contains the fatty acid, but moms do have to be sure to get enough in their diets.
In order to support the infant, the body will pull nutrients from the mother’s body, during pregnancy and while breast-feeding. If mom is not well nourished to begin with, she is likely to suffer from symptoms of nutritional deficiencies. When it comes to the omega 3 DHA, those... (read more)

13. The Growing Importance of Omega3 Acid
October 12, 2009
Let me tell you a quick story. The omega3 acid is a polyunsaturated fat that has a carbon double bond in the third position from the methyl end of the fatty-acid chain. These long-chained fatty acids are unlike other dietary fats, in that they are good for our health and essential for normal bodily functions.
The omega6s are similar, in that they are unsaturated fats, with a carbon double bond. But, the position of the carbon bond is in the sixth position from the end. They are also essential for normal bodily functions.
In the early days of nutritional research, scientists foc... (read more)

15. Omega-3 and Omega-6: Striking the Right Balance
October 09, 2009
Do you remember when you were young and your parents forced you to take ?sh oil by the teaspoon, saying that it was good for you? Guess what? They were right!
Omega-3 and Omega-6 are called essential fatty acids (EFAs) and are poly-unsaturated fats. Since your body cannot manufacture EFAs, they need to be obtained from the food you eat or the supplements you take. Linoleic Acid (LA) is a primary member of the Omega-6 fatty acids and can be found in leafy vegetables, seeds, nuts, grains, and vegetable oils like corn oil, soybean oil and sun?ower oil. Vegetarian diets tend to be very high i... (read more)
