The full article cited below demonstrates that most
negative attributes are
generally form the most promoted synthetic fats which contain trans
fatty
acids by the virtue of how they are manufactured. This includes
most
polysaturated, unsaturated and even monounsaturated fats. I have
yet to
find a good study linking saturated fats to all the bad things on
hears
about them! The more I study saturated fats the more good things
I find
about them... Yet again it appears that one cannot go wrong in going
back
to the most natural products which have been maligned in the search
for
ever higher profits of the synthetics and modified foods.

"The issue of the trans fatty acids as a causative factor
in cancer remains
underexplored, but recent reports have found a connection. Bakker
and
colleagues (1997) studied the data for the association between breast
cancer incidence and linoleic acid status across European countries,
since
animal and ecological studies had suggested a relationship. They
found that
the mean fatty acid composition of adipose did not show an association
with
omega-6 linoleic acid and breast, colon or prostate cancer. However,
cancers of the breast and colon were positively associated with
the trans
fatty acids. Kohlmeier and colleagues (1997) also reported that
data from
the EURAMIC study showed adipose tissue concentration of trans fatty
acids
having a positive association with postmenopausal breast cancer
in European
women."
"Lowering the trans fatty acids in foods in the US can only
be done by
returning to the use of the natural, unhydrogenated and more saturated
fats
and oils."
RESEARCH SHOWING BENEFICIAL EFFECTS OF EATING
THE MORE SATURATED FATS
One major concern expressed by the nutrition community is related
to
whether or not people are getting enough elongated omega-3 fatty
acids in
their diets. The elongated omega-3 fatty acids of concern are
eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Some
research
has shown that the basic omega-3 fatty acid, linolenic acid, is
not readily
converted to the elongated forms in humans or animals, especially
when
there is ingestion of the trans fatty acids and the consequent inhibition
of the delta-6-desaturase enzyme. One recent study (Gerster, 1998),
which
used radioisotope-labelled linolenic acid to measure this conversion
in
adult humans, showed that if the background fat in the diet was
high in
saturated fat, the conversion was approximately 6% for EPA and 3.8%
for
DHA; whereas, if the background fat in the diet was high in omega-6
polyunsaturated fatty acids (PUFA), the conversion was reduced 40-50%.
Nanji and colleagues (1995) reported that a diet enriched with saturated
but not unsaturated fatty acids reversed the alcoholic liver injury
in their animals which was caused by dietary linoleic acid. These
researchers concluded that this effect may be explained by the down-regulation
of lipid peroxidation. This is another example of the need for adequate
saturated fat in the diet.
Cha and Sachan (1994) studied the effects of saturated fatty acid
and
unsaturated fatty acid diets on ethanol pharmacokinetics. The hepatic
enzyme alcohol dehydrogenase and plasma carnitines were also evaluated.
The
researchers concluded that dietary saturated fatty acids protect
the liver
from alcohol injury by retarding ethanol metabolism, and that carnitine
may be involved.
Hargrove and colleagues (1999) noted the work of Nanji et al. and
postulated that they would find that diets rich in linoleic acid
would also
cause acute liver injury after acetaminophen injection. In the first
experiment, two levels of fat (15g/100g protein and 20g/100g protein),
using corn oil or beef tallow, were fed. Liver enzymes indicating
damage
were significantly elevated in all the animals except for those
animals fed
the higher level of beef tallow. These researchers concluded that
"diets
with high [linoleic acid] may promote acetaminophen-induced liver
injury
compared to diets with more saturated and mono-unsaturated fatty
acids".
