Omega-3, one of the fatty acids found in fish oils, ?acts to lower the
levels of cholesterol and LDL (low-density lipoproteins) in the
blood,? says WebMD (?Fish Oil,?
http://www.medterms.com/script/main/art.asp?articlekey=13979 ) ?LDL
cholesterol is the ?bad? cholesterol.?
American Family Physician adds: ?Omega-3 fatty acids lower plasma
triglyceride levels?by inhibiting the synthesis of very-low-density
lipoprotein (VLDL) cholesterol and triglycerides in the liver. A
review of human studies concluded that approximately 4 g per day of
omega-3 fatty acids reduced serum triglyceride concentrations by 25 to
30 percent, increased serum low-density lipoprotein (LDL) cholesterol
levels by 5 to 10 percent, and increased high-density lipoprotein
(HDL) cholesterol levels by 1 to 3 percent. Total cholesterol was not
significantly affected?High dosages of fish oil may increase LDL
cholesterol levels, but the clinical relevance of this finding remains
unclear.? (?Omega 3 Fatty Acids,?
?Those who follow a Mediterranean-style diet tend to have higher HDL
(?good?) cholesterol levels,? says the University of Maryland Medical
Center website. ?Similar to those who follow a Mediterranean diet,
Inuit Eskimos, who consume high amounts of omega-3 fatty acids from
fatty fish, also tend to have increased HDL cholesterol and decreased
triglycerides (fatty material that circulates in the blood). In
addition, fish oil supplements containing EPA and DHA have been shown
to reduce LDL (?bad?) cholesterol and triglycerides. Finally, walnuts
(which are rich in ALA) have been shown to lower total cholesterol and
triglycerides in people with high cholesterol.? (?
Omega-3 Fatty Acids,?
For additional information about Omega-3 in general, I highly
recommend the American Family Physician article noted above.

Hello again saregamapa~
I?m sorry I confused you! Unfortunately, clinical evidence is often
contradictory. However, most studies show that omega-3:
? Lowers LDL (?bad? cholesterol)
? Increases HDL (?good? cholesterol)
? Has little or no effect on overall cholesterol
However, some studies also show LDL going up a little with omega-3
intake. As American Family Physicians says, ?high dosages of fish oil
may increase LDL cholesterol levels, but the clinical relevance of
this finding remains unclear.? (?Omega 3 Fatty Acids,?
I hope this makes the medical facts more clear.
