The mechanism by which
boiled coffee affects cholesterol metabolism is unclear.
Ground
coffee evidently does not need to be actively boiled in
water to produce a hypercholesterolemic brew.
We10
recently isolated a lipid-rich fraction from
boiled coffee that markedly raised cholesterol levels in
volunteers, and we suggested that filtered coffee does
not raise serum cholesterol levels because it has a low
lipid content. We now present a direct test of this
hypothesis.
the
group drinking boiled coffee, the serum total choles- terol concentration rose, on average, by 0.42 mmol/1
(16 mg/dl; 95% confidence interval [CI] for differ- ence with the boiled and filtered-coffee group, 0.14- 0.71,^=0.005) and LDL cholesterol by 0.41 mmol/1
(16 mg/dl; 95% CI, 0.16-0.66, p=0.002) in compar- ison with the group drinking boiled and filtered coffee.
HDL cholesterol fell slightly by 0.05
mmol/1 (2 mg/dl) in the boiled-coffee group relative
to the boiled and filtered-coffee group, and it in-
creased by 0.05 mmol/1 (2 mg/dl) in the group in
which all coffee was eliminated
Likewise, adjustment for changes in
body weight and for changes in the reported intake of
saturated and polyunsaturated fat and dietary cho- lesterol had very little influence on the result.
Our findings show that the paper filter plays a
crucial role in eliminating the hypercholesterolemic
factor from coffee. The cholesterol-elevating effect of
boiled-type coffee disappeared when the liquid was
poured through a paper filter before consumption.
Recently, we10 showed that
the lipid-rich supernatant of boiled coffee obtained
after centrifugation raised serum cholesterol levels
by 23%, and we suggested that the cholesterol-
elevating factor is contained in the lipid. The present
study now shows that boiled-type coffee loses both its
lipids and its cholesterol-raising properties after fil-
tration through a paper filter and that the lipid is
retained in the paper filter.
. The increase of 11% in serum latho- sterol in the group drinking boiled coffee was paral- leled by a 9% increase in serum cholesterol level. This might suggest that increased synthesis of choles- terol does not play a major role in the elevation of
serum cholesterol levels.
decreased clearance
of VLDL with an increased conversion to LDL or a
decreased clearance of LDL cholesterol could pro-
vide alternative explanations for the cholesterol-
raising effect of boiled coffee. However, our findings
do not exclude effects of boiled coffee on lipoprotein
synthesis and turnover.
This study shows now that even filtered coffee have that effect of raising total cholesterol and LDL but still not pronounced as much as un-filtered. European Journal of Clinical Nutrition - Filtered coffee raises serum cholesterol: results from a controlled study
Will this improve steroidogenesis and since coffee already have that effect of improving progesterone this means only that those effect are more potent without using paper filter?
.Turkish(or bosnian coffee(-see on wiki)) un-filtered coffee. In all Balkan countries unfiltered coffee is still widely used.
French press also and espresso should have those effects compared to paper filter.
I also noticed that unfiltered(bosnian,turkish) or (french press ) coffee is much more stimulating and great for the bowels and bowel movements. Maybe from fine coffee solids that are able to pass in those preparation methods?
They act like cascara or maybe more correctly like activated charcoal since it is roasted ?
