Oxidized lipids in the diet are a source of oxidized lipid in chylomicrons of human serum.

[Guest guest]

Hi All,

After reading this and knowing that high temperature frying generates oxidized

fatty acids in the frying oil / fat, do

you still think you are doing your body a service eating fried food? I think

not....................

If you still need to eat fried food, do it in virgin coconut oil as this is the

least heat effected oil.

Note well the conclusions of the study:

" These data demonstrate that in humans dietary oxidized lipids are absorbed by

the small intestine, incorporated into

chylomicrons, and appear in the bloodstream, where they contribute to the total

body pool of oxidized lipid. "

Oxidized lipids in the diet are a source of oxidized lipid in chylomicrons of

human serum.

We examined whether oxidized lipids in the diet determine the levels of oxidized

lipid in human postprandial serum

chylomicrons.

After we fed subjects control corn oil containing low quantities of oxidized

lipid, the levels of conjugated dienes in

the chylomicron fraction were low (9.67 +/- 0.92 nmol/mumol triglyceride), and

no thiobarbituric acid-reactive

substances (TBARS) could be detected.

However, when subjects were fed a highly oxidized oil, the conjugated diene

content in chylomicrons was increased

4.7-fold to 46 +/- 5.63 nmol/mumol triglyceride, with 0.140 +/- 0.03 nmol

TBARS/mumol triglyceride.

When subjects were fed medium-oxidized oil, the degree of oxidation of the

chylomicron lipids was moderately increased

(21.86 +/- 2.03 nmol conjugated dienes/mumol triglyceride).

Additionally, we found that chylomicrons isolated after ingestion of oxidized

oil were more susceptible to CuSO4

oxidation than chylomicrons isolated after ingestion of the control oil.

The lag time for oxidation decreased from 4.30 +/- 0.40 to 3.24 +/- 0.51 hours

(P < .05). [****They were much more

easily oxidized by free radicals and thus may increase the rate of occurrence of

oxidized LDL..gw****]

These data demonstrate that in humans dietary oxidized lipids are absorbed by

the small intestine, incorporated into

chylomicrons, and appear in the bloodstream, where they contribute to the total

body pool of oxidized lipid.

Hi CB,

Just understand any frying will cause oxidation of the oil and some formation of

trans fats. The more double bonds the

worst. Sure olive oil is better than veggie oils but coconut oil is better

still. Also frying formes glucose to

protein cross links (called AGEPs), which have been shown to be age

accelerating.
