		Linoleic acid is considered an “omega-6” or “n-6” fatty acid because the first of its double bonds occurs at the sixth carbon from the omega end.
		Linolenic acid, or alpha-linolenic acid, is also an 18-carbon polyunsaturated fatty acid, but it is classified as an “omega-3” or “n-3” fatty acid because its first double bond (of three) is at the third carbon from the omega end.
		Fatty acid composition in major depression: Decreased omega-3 fractions in cholesteryl esters and increased C20:4 omega 6/C20:5 omega 3 ratio in cholesteryl esters and phospholipids.

	Essential Fatty Acids - Omega 3 and Omega 6
		Both omega-3 (alpha-linolenic acid) and omega-6 (linoleic acid) are bountiful in the leafy plants consumed by roaming animals, providing nearly equal ratios of these EFAs.
		Fatty acids are composed of long carbon chains with a methyl group at one end, and an acid group at the other.
		Of the listed fatty acids, only omega-6 and omega-3 are categorized as "essential" because they cannot be synthesized in the body and therefore must be derived from the diet.

	All About Fatty Acids
		Fatty acids are fats, but with a certain chemical structure.
		All fatty acids are chains of carbon atoms with oxygen atoms hooked on at one end (the alpha end), and three hydrogen atoms hooked on at the other end (the omega end).
		Because the body uses the same pathways to metabolize both omega-6 and omega-3 fatty acids, finding the ideal ratio of the two types of fatty acids is important.

	Omega-3 fatty acids: research news
		Consequently a greater consumption of omega-3 fatty acids and a higher ratio of omega-3 to omega-6 fatty acids reduce the tendency to vasoconstriction.
		Some of the favorable effects of omega-3 fatty acids specifically important in the prevention and treatment of kidney diseases are among others: vasodilatation, inhibition of inflammatory reactions, decrease of platelet aggregation and a reduction of blood viscosity.
		If this highly unsaturated omega-3 fatty acid, which is an essential part of the neuronal cell membranes, is replaced by an omega-6 fatty acid, changes in the membrane properties may occur, which increase the vulnerability to depression, as is elucidated by the authors.

	Omega-3 Fatty Acids
		In summary, Dr. Simopoulos wrote: “Omega-3 and Omega-6 fatty acids are not interconvertible in the human body and are important components of practically all cell membranes.
		Whereas cellular proteins are genetically determined, the polyunsaturated fatty acids (PUFA) composition of all cell membranes is to a great extent dependent on the dietary intake.
		Therefore appropriate amounts of dietary Omega-6 and Omega-3 fatty acids need to be considered in making dietary recommendations, and these two classes of PUFAs should be distinguished because they are metabolically and functionally distinct and have opposing physiological functions.

	Workshop on the Essentiality of Omega-6 and Omega-3 Fatty Acids
		The range of functional effects of omega-3 fatty acid deficiency and supplementation during development and their impact on later vision, cognition and behavior are not completely understood, nor are the relationship of these effects to the dose of dietary DHA and the age and duration of dietary intervention.
		With the findings by some psychiatrists that these same fatty acids are apparently beneficial in the management of depression and bipolar behavioral disorders, the finding of an important effect of the fatty acids on the electrical activity of brain cells may have broader health implications than just to cardiovascular diseases.
		Empirical equations presented by Lands indicate that both increasing the intake of n-3 fatty acids and decreasing that of n-6 fatty acids are necessary for effectively decreasing the n-6 eicosanoid precursors in phospholipids and thereby decreasing cancer mortality.

	Consuming linoleic acid, omega-6 fatty acids cuts prostate cancer risk, study shows
		In a study of middle-aged men, high intake of linoleic acid, an unsaturated fatty acid found in certain plants and vegetables, seemed to lower the risk of prostate and other cancers, Finnish researchers report.
		The investigators studied the association between dietary fatty acid and cancer risk in 2002 middle-aged men who were cancer-free during the first 4 years of the study.
		Laaksonen and colleagues conclude, "substitution of linoleic acid for saturated fat in middle-aged men consuming a high saturated-fat diet may decrease the risk of prostate and other cancers," although they acknowledge that other nutrients associated with vegetable fats may be responsible for the protective effect.
