Sorry, but I do not speak Italian. :(

The fat acids trans that they are found naturally in some alimony, are
from considering negatively like those manufacturers who find
themselves in the fat people hydrogenate to you like those of the
margarine?

In this page there is a table with the medium values of trans in some
alimony (given USA).
http://www.hsph.harvard.edu/nu­tritionsource/fats.html

The percentages are on the fat people totals, not on the all up
weight of the food.

In the butter as an example 5% of the fat people totals, in the oil of
palm 0%, the margarine from the 5 to the 23 for hundreds to second of
the type.

I task that the butter is cmq to prefer to the margarina also for
other reasons.

As an example, the possible other metal or presence residual nichel in
the working of the margarina.

And the fact that not having info clear on the content of trans in the
margarine, we cannot know if ce they are 5% or 23%!

In the USA from 2006 the indication of the content of trans will be
obligatory in label, but it does not seem to me that in Italy the same
one is previewed.

In any case, premised all that, like considering those 5% of trans on
the fat people of the butter?

My idea is that, in any case, pack-saddles not to exaggerate with the
things, therefore a slice of bread and every butter a lot will not
kill to me! :)

Or even bread and butter and marmellata, for being peccaminosi to the
maximum;)
