|Abstract: ||Peanut oil has been associated with
reduced levels of plasma cholesterol and
triacylglycerol, possibly due to its high
monounsaturated (MUFA) lipid profile.
This study evaluated the effects of
peanut oil intake on blood lipid levels of
healthy, normolipidemic, young adults
(18-50 y/o). One hundred twenty nine
subjects were recruited in Brazil (32),
Ghana (64), and in the United States
(33). Men (64) and women (65) were
assigned to 1 of 4 experimental groups:
control (32), peanut (32), safflower (33),
and olive oil (32). Participants received a
daily milk shake containing 30% of their
basal energy requirement as 1 of the test
oils for 8 weeks, except the control
group, which did not receive the shake.
The levels of total cholesterol, HDL-
cholesterol, LDL-cholesterol, and tria-
cylglycerol were assayed at baseline and
on weeks 4 and 8. Waist/hip ratio, blood
pressure, and heart rate were also evalu-
ated. The concentration of LDL-choles-
terol was significantly reduced in the
safflower group (p<0.05). Systolic and
diastolic blood pressures were consis-
tently lower in the olive oil group and
for the Ghanaian participants in the peanut oil group (p<0.05). In conclusion,
safflower oil elicited a stronger LDL-
lowering property than peanut and olive
oil, while olive oil, and to a lesser extent
peanut oil, were more effective at reduc-
ing blood pressure. The weak and inter-
mediate effects of the peanut oil on
cholesterol and blood pressure relative
to the other oils suggest a contribution
of its MUFA composition as well as
other constituents in whole peanuts.|
