Was Humanity's Rise to Preeminence Fueled By Fish Oils? - 7


Cutting to the Chase
    Because of my abysmal ignorance concerning the validity of Dr. Barry Sears' Biochemistry in "The Omega Rx Zone", I can only examine the differences between Sr. Sears' guidelines, Dr. Perricone's guidelines, and the recommendations of conventional organizations such as the American Heart Association. 
We Can All Agree That Modern Westerners Need More Fish Oil.
    The White House has just recommended that people consume more omega-3 fats. The following table shows the estimated US current omega-3 fat intake versus some recommended consumptions.

Source of numbers Daily omega-3
fats, grams
Estimated U. S. average intake 0.125
Am. Heart Assoc. (AHA) Recommendation 0.250
Dr. Perricone's Recommendation 1.000
Am. Heart Assoc. (AHA), Existing CVD 1.000
Am. Heart Assoc (AHA)., High triglycerides 2.000 to 4.000*
Teaspoon of cod liver oil 2.500
Dr. Sears' recommendation 2.500
Neolithic humans (according to Dr. Sears) 3.000
Eskimos 7.000 to 10.000
Harvard bipolar disorder study 10.000

* - More than 3 gms. daily should be taken under a physician's care (per the AHA) because of anti-coagulant properties.

    Taken from the American Heart Assosiation's "New guidelines focus on fish, fish oil, omega-3 fatty acids":
"Although the mechanisms responsible for omega-3 fatty acidsí reduction of CVD risk are still being studied, research has shown:

Ask the Doctor- Daily Intake of Omega-3 Fatty Acids.
    Dr. Sears recommends that we take 2.5 grams a day of total EPA and DHA, corresponding to something like 3 grams a day of total omega-3 fatty acids.
    For people seeking to

    These latter recommendations probably wouldn't enlist the support of most medical organizations. However, Dr. Sears' baseline recommendation of 2.5 grams a day of combined EPA (EicosaPentaenoic Acid) and DHA (DocosaHexaenoic Acid) fall with in the AHA guidelines for those with high triglyceride levels.

Bottom Line:  Dr. Sears' maintenance dose of 2.5 grams of EPA plus DHA per day sounds like an acceptable dosage level.
