It seems?

may, may, may....after all this time and energy spent on research, definite

right. Not hard at all. No one *has* to eat lots and lots of meat fat to
do LC.

Hi ,
I finished a Master in Clinical and Dietary Nutrition, the argument of
my Thesis was " Role of the essential fatty acids omega 6/omega 3 in
the diet " ; if someone it's interested to consult it (index,
bibliografy and preview is free of course) can find it to this
address:

Sorry but the language is Italian because I'm from Italy

Here's the translation of the abstract (THANK'S STEVE!)

"The Role of Omega 3 and Omega 6 Essential Fatty Acids in Diet." by
Alessandro Ficarra

Fatty acids are among the most important and common components of all
classes of lipids and therefore are amply represented in living
organisms where they have structural, energy and metabolic functions.
They can be saturated (no fats unlinked) or present as one or more
unlinked fats (mono or polyunsaturated).

Within the category of the polyunsaturated fatty acids, can be
distinguished the essential fatty acids (EFA). Their 'essentialness'
derives from the fact that they cannot be synthesized within the human
organism and must therefore be necessarily introduced with the diet.
The essential fatty acids are truly and properly two:
Linoleic acid (an omega 6 fatty acid) and Linolenic acid (an omega
three).

The omega three fatty acids are normally present in the marine foods,
in certain plants and also in certain animal products such as chicken,
turkey and eggs, though the more important omega six fatty acids are
present overall in the oils of seeds.

In the course of the last decade numerous clinical research studies
and experiments and overall epidemiological analysis have focused
their attention on the role that essential fatty acids may have within
physiological phases (pregnancy, breast-feeding, adolescence, etc.)
which relate to prevention and treatment of such illnesses as
cardiovascular disease, some types of tumors, and Alzheimer's
dementia.


Thank you for your attention..bye

The association of dietary fat and plant foods with endometrial cancer
(United States).

Littman AJ, Beresford SA, White E.

Department of Epidemiology, University of Washington, Seattle,
USA.

OBJECTIVES: To examine the associations of dietary fat and selected
plant foods with endometrial cancer in a population-based case-control
study. METHODS: Six hundred and seventy-nine incident cases of
endometrial cancer diagnosed between 1985 and 1991, and 944
population-based controls completed a 98-item semi-quantitative
food-frequency questionnaire and a detailed in-person interview which
collected information on endometrial cancer risk factors. Logistic
regression was used to estimate odds ratios (OR) and their 95%
confidence intervals (CI) of endometrial cancer, adjusted for age,
county, energy intake, hormone use, smoking and, in separate models,
for body mass index (BMI: kg/m2). RESULTS: Percent energy from fat was
associated with an increased risk of endometrial cancer (highest
quintile cf. lowest: OR = 1.8, 95% CI 1.3-2.6), with saturated and
monounsaturated fats being the main contributors of risk. There was a
stronger association between dietary fat and endometrial cancer among
groups with higher circulating estrogen levels (i.e. women with higher
BMI, users of unopposed estrogens, non-smokers, and younger age at
menarche). Consumption of fruits or vegetables was inversely
associated with endometrial cancer risk (highest quintile cf. lowest:
OR = 0.65, 95% CI 0.46-0.93 and OR = 0.61, 95% CI 0.43-0.88,
respectively). Further adjustment for BMI resulted in little or no
attenuation of the ORs and associated CIs. CONCLUSIONS: These results
provide support for the theory that a low-fat, high-fruit and
high-vegetable diet may reduce the risk of endometrial cancer, and
that these dietary factors may act independently of the effect of BMI.

Omega-6 fats are associated with cancer risk, not omega-3, so it
depends on where you're getting your protein from.

Here's some plain English info for you:
