Marilyn's Transfatty Milk

Having beer with Marilyn (fellow graduate student) is always educational but when she starting talking about transfats in milk I was like," hello?! trans fats are only a result of synthetic hydrogenation of vegatable oils!"

Apparently Marilyn was right.
From Marilyn:

hey guys, I was not in the field...

there is naturaly occuring trans fat in animal products like meat and dairy, but
those are good for you.

''Where do trans fats come from?''

''Some low levels of trans fat have always been found naturally in our food supply
in the fat in the meat and milk from ruminant animals (e.g. cows; sheep). These fats
are produced by the normal action of bacteria in the gut of ruminants.''

or

''Trans fat can be found in vegetable shortenings, some margarines, crackers,
candies, cookies, snack foods, fried foods, baked goods, and other processed foods
made with partially hydrogenated vegetable oils. Small amounts of naturally
occurring trans fat can be found in some animal products, such as butter, milk
products, cheese, beef, and lamb.''

check out that article were they talk about good and bag trans fat.

to make it event better I pulled out some a paper from the journal of dairy science
but i could only get the abstract at home. let me know if you can get the hole
papers.

Major advances in nutrition: impact on milk composition.
J Dairy Sci. 2006 Apr;89(4):1302-10.

Examination of the persistency of milk fatty acid composition responses to fish oil
and sunflower oil in the diet of dairy cows. J Dairy Sci. 2006 Feb;89(2):714-32.
end Marilyn's quote.

I pretty much have been proven wrong. However I have an issue with the notion that there are healthy transfats. The only reason the cited article gives that naturally occurring transfats are healthy is that they are natural. No proof.
Perhaps getting transfats exclusively from natural sources is okay however, but only because they are in such low abundance.
