WRONG! It's crap!
see for yourself...

Olive, soybean and palm oils intake have a similar acute detrimental
effect over the endothelial function in healthy young subjects.
BACKGROUND AND AIM: Currently, more than 30% of the caloric intake in
the Colombian population comes from vegetable oil consumption mainly by
the ingestion of deep-fried foods. Recently, it has been reported that
unsaturated fatty acid rich oils have a beneficial effect on the
endothelial function. Nevertheless, it is well know that the deep-frying
process alters the chemical composition of vegetable oils and can
produce adverse effects in the endothelial function. OBJECTIVE: To
evaluate the acute effect of the ingestion of large amounts of olive,
soybean and palm oils, fresh and at two different deep-fry levels, on
the glucose and lipid profiles and the endothelial function. METHODS AND
RESULTS: Ten healthy young volunteers were included in the study. After
performing a baseline evaluation of cardiovascular risk factors and
drawing a fasting blood sample, subjects were exposed to a randomly
assigned potato soup meal containing 60 mL of one of three different
vegetable oils (olive, soybean and palm), either fresh or at one of two
different deep-fry levels (10 and 20 fries, respectively). Flow-mediated
vasodilation (FMD) was performed in fasting conditions and 3h after the
intake of the oil rich meal. Furthermore, blood samples were taken at
these stages for the lipid profiles and plasma glucose determinations.
All the meals resulted in a similar acute endothelial impairment (FMD
decrease of 32.1%, confidence interval [CI] 95%, 28.0-36.2) and
postprandial increase in triglycerides (27.03%, CI 95%, 20.5-33.3),
independently of the type of oil ingested (p=0.44) and regardless of its
deep-fry level (p=0.62). No correlation was found between endothelial
impairment and postprandial triglyceride increment (r=-0.22, p=0.09).
CONCLUSIONS: No difference was found in the acute adverse effect of the
ingestion of different vegetable oils on the endothelial function. All
the vegetable oils, fresh and deep-fried, produced an increase in the
triglyceride plasma levels in healthy subjects.
NO oil is healthy because it's a PROCESSED concentrated source of FAT. Fats are not good just SOME fats are LESS unhealthy than others.
OLIVE OIL? THROW IT OUT! ITS CRAP!
ps GIVE BEAST DA BOOT TOO!
