Omega 3 contains the essential fat omega-3, the most beneficial
form containing two fatty acids, EPA and DHA, can only be found
in fish oil. These two fatty acids are essential to fight or prevent
both physical and mental disease. The tremendous health benefits
of fish oil would best be derived from eating fatty cold-water
fish, but almost all fish are contaminated with unsafe levels of mercury
and other contaminants[iv] and I advise against eating fish unless
it has been lab-tested.
FDA Recognizes Health Benefits of Omega-3
Both the omega-6 and omega-3 fatty acids belong to a group of polyunsaturated
fats called 'essential' because they are necessary to life and to
health yet we cannot make them in the body - they must be obtained
from diet. They cannot be inter-converted and both must be present
in the diet in a proper balance for good health.
Their differences lie in their chemical structure and their roles
in the body.
As polyunsaturated fatty acids, both the omega-6 and the omega-3
families have more than one double bond in the carbon chain. All
fatty acids in the omega-6 family contain their first double bond
between the 6th and7th carbon atoms (counted from the methyl (CH3)
terminal carbon atom and the omega-3 family of fatty acids have their
first double bond between the 3rd and 4th carbon atom.
Both families of fatty acids are vital components of membranes and
are used by the body in the production of eicosanoids, a vast range
of highly bioactive substances (prostaglandins, leukotrienes, lipoxins)
but the activity of these metabolites varies. For example, the eicosanoids
derived from omega-6 are in general more active (or reactive) than
those produced from omega-3 and omega-6 is aggregatory whereas oega-6
is pro-aggregatory.
 Basically, the omega-3s have anti-inflammatory benefits and help
prevent heart disease, whereas omega-6s lower blood cholesterol and
support the skin.
EFAs are involved in normal physiology, including:
• regulating pressure in the eye, joints, and blood vessels, and mediating
immune response
• regulating bodily secretions and their viscosity
• dilating or constricting blood vessels
• regulating collateral circulation
• directing endocrine hormones to their target cells
• regulating smooth muscles and autonomic reflexes
• being primary constituents of cell membranes
• regulating the rate of cell division
• maintaining the fluidity and rigidity of cellular membranes
• regulating the inflow and outflow of substances to and from cells
• transporting oxygen from red blood cells to the tissues
• maintaining proper kidney function and fluid balance
• keeping saturated fats mobile in the blood stream
• preventing blood cells from clumping together (blood clots that can be
a cause of heart attack and stroke)
• mediating the release of inflammatory substances from cells that may trigger
allergic conditions
• regulating nerve transmission and communication
• If the diet is deficient in either omega-6 or omega-3 long-term degenerative
illnesses will result.
