Psyllium fiber reduces
hypercholesterolemia and improves glycemic control.
Even if this study was
made on men with type 2 diabetes, this kind of fiber could be useful
for healthy people too, expecially in a body-fat control strategy.

Abstract
BACKGROUND:
Water-soluble dietary
fibers decrease postprandial glucose concentrations and decrease
serum cholesterol concentrations. This study examined the effects of
administering psyllium to men with type 2 diabetes.
OBJECTIVE:
The objective was to
evaluate the safety and effectiveness of psyllium husk fiber used
adjunctively to a traditional diet for diabetes in the treatment of
men with type 2 diabetes and mild-to-moderate hypercholesterolemia.
DESIGN:
After a 2-wk dietary
stabilization phase, 34 men with type 2 diabetes and mild-to-moderate
hypercholesterolemia were randomly assigned to receive 5.1 g psyllium
or cellulose placebo twice daily for 8 wk. Serum lipid and glycemic
indexes were evaluated biweekly on an outpatient basis and at weeks 0
and 8 in a metabolic ward.
RESULTS:
In the metabolic ward, the
psyllium group showed significant improvements in glucose and lipid
values compared with the placebo group. Serum total and
LDL-cholesterol concentrations were 8.9% (P < 0.05) and 13.0% (P =
0.07) lower, respectively, in the psyllium than in the placebo group.
All-day and postlunch postprandial glucose concentrations were 11.0%
(P < 0.05) and 19.2% (P < 0.01) lower in the psyllium than in
the placebo group. Both products were well tolerated, with no serious
adverse events related to treatment reported in either group.
CONCLUSION:
The addition of psyllium
to a traditional diet for persons with diabetes is safe, is well
tolerated, and improves glycemic and lipid control in men with type 2
diabetes and hypercholesterolemia.

Benefici dell'integrazione
con fibra di Psyllium
La fibra di Psyllium
riduce l'ipercolesterolemia e migliora il controllo glicemico.
Anche se questo studio è
stato fatto su diabetici di tipo 2, questo tipo di fibra può essere
molto utile anche negli individui sani, specialmente se inserita
nelle strategie di controllo del grasso corporeo.
