Subject: Re: omega-3 in Albacore tuna
Hello Shirley,
You can access the USDA data base on the nutrient composition of foods by
going to this link:
http://www.nal.usda.gov/fnic/foodcomp/search/
When the page asks for the food, just type in "tuna". You will be asked to
choose which forms you want, and many are provided.
Your original request did not say whether you wanted information on fresh
tuna, or canned, nor which species.
In addition to the information on canned white (albacore) and light (mostly
skipjack) tuna from USDA, you may be interested in another albacore
population.
Troll-caught albacore tuna from the west coast of the U.S. is a different
population of albacore from the mature fish caught in the north and south
Pacific. These are juvenile fish, very high in fat and low in methylmercury.
They have 2 to 3 times as much long-chain omega-3 fatty acids (EPA and DHA)
as mature albacore.
These troll-caught albacore are mostly sold in European markets but some is
available from specialty canners on the west coast.
In a paper by Wheeler and Morrissey, J. Aquatic Food Product Technology, the
published omega-3 fatty acid content (total) for these fish ranged from 2.1
+/- 0.5 to 3.5 +/- 0.4 g/100 g tissue (raw).
I hope this information is helpful.

Some data for canned albacore is given in
S.M. Shim, L.E. Dorworth, J.A. Lasrado, and C.R. Santerre. (2004). Mercury
and Fatty Acids in Canned Tuna, Salmon, and Mackerel. Journal of Food
Science, 69(9), 681-684. Available at
http://www.cfse.purdue.edu/media/news/MercuryFattyAcidsCanned.pdf
A surf of PubMed gave the following 2 papers.
Castro Gonzalez MI, Montano Benavides S, Perez-Gil Romo F. Fatty acids of
the tuna of different fishing areas of the Mexican Pacific, canned in oil
and water. Arch Latinoam Nutr. 2001 Dec;51(4):407-13.
Romero N, Robert P, Masson L, Luck C, Buschmann L. Fatty acid composition
and cholesterol content in naturally canned jurel, sardine, salmon, and
tuna. Arch Latinoam Nutr. 1996 Mar;46(1):75-7.
