M. Pfeuffer et al., EFFECT OF FEEDING BUTTER OR BREGOTT ON PLASMA AND LIPOPROTEIN LIPIDS OF MINIATURE PIGS, Milchwissenschaft, 49(3), 1994, pp. 132-134
It was examined whether a moderate exchange of saturated for polyunsat
urated fatty acids would favourably affect plasma lipid levels. This w
as done by feeding miniature pigs under a strictly controlled experime
ntal regimen ''Western style'' diets with either butter or Bregott, a
spread composed of butter and soybean oil. There was a 6.7 % decrease
of total plasma cholesterol with Bregott instead of butter (p < 0.05),
mainly due to a decrease of cholesterol in VLDL and LDL. This is only
a weak effect, but it might be supportive in an overall approach towa
rds a more prudent diet. Plasma cholesterol ester fatty acid pattern w
as modified according to the pattern of the dietary fat. Levels of ste
aric acid were 31 % lower and those of linoleic acid 89 % higher durin
g the Bregott period (p < 0.01). Levels of oleic acid were decreased b
y 40 % (p < 0.05) during the Bregott period, probably due to relativel
y high levels during the butter period induced by a marginal supply of
essential fatty acids.
