VI. THE LATEST ON THE TRANS FATTY ACIDS
Both the United States and
Canada will soon require labeling of the trans fatty acids,
which will put coconut oil in a more competitive position than
it has been in the past decade. A fear of the vegetable oil
manufacturers has always been that they would have to label
trans fatty acids. The producers of trans fatty acids have
relied on the anti-saturated fat crusade to protect their
markets. However, the latest research on saturated fatty acids
and trans fatty acids shows the saturated fatty acids coming
out ahead in the health race.
It has taken this last
decade, from 1988 to 1998, to see changes in perception. During
this period, the trans fatty acids have taken a deserved
drubbing. Research reports from Europe have been emerging since
the seminal report by Mensink and Katan in 1990 that the trans
fatty acids raised the low density lipoprotein (LDL)
cholesterol and lowered the high density lipoprotein (HDL)
cholesterol in serum. This has been confirmed by studies in the
U.S. (Judd et al 1994, Khosla and Hayes 1996, Clevidence
1997).
In 1990, the lipids research
group at the University of Maryland published a paper (Enig et
al 1990) correcting some of the erroneous data sponsored by the
food industry in the 1985 review by the Life Sciences Research
Office of Federation of American Societies for Experimental
Biology (LSRO-FASEB) (Senti 1985) of the trans fatty
acids.
Also, in 1993, a group of
researchers at Harvard University, led by Professor Walter
Willett, reported a positive relationship between the dietary
intake of the trans fatty acids and coronary heart disease in a
greater than 80,000 cohort of nurses who had been followed by
the School of Public Health at Harvard University for more than
a decade.
Pietinen and colleagues
(1997) evaluated the findings from the large cohort of Finnish
men who were being studied for a cancer prevention study. After
controlling for the appropriate variables including several
coronary risk factors, the authors observed a significant
positive association between the intake of trans fatty acids
and the risk of death from coronary disease. There was no
association between intakes of saturated fatty acids, or
dietary cholesterol and the risk of coronary deaths. This is
another example of the differences between the effects of the
trans fatty acids and the saturated fatty acids and further
challenge to the dietary cholesterol
hypothesis.
