Glucose and insulin level
Table 3 also reveals that that treatments exhibited
significant differences on glucose and insulin in the
trial-III and IV while in trial-I and II differences were
non-significant. The results indicated that glucose level
varied from 90.44 ± 4.79 to 93.55 ± 6.01 mg.dL in normal
rats, while in high cholesterol fed rats, the same trait varied
from 101.51 ± 4.58 to 105.60 ± 6.61 mg/d. The results
showed some significant glucose lowering abilities of functional
drink in group of rats fed on high sucrose or high
cholesterol and sucrose diets. In contrast to lipid profile,
experimental drink containing EGCG reduced the trait
better than catechins based functional drink. Although,
variations between functional drinks were statistically
non-significant but higher decrease in glucose levels was
more important. The trait decreased by 10.10 and 12.33%
in catechins and EGCG based functional drinks, respectively.
The glucose level decreased by 6.91 and 8.06% in experimental
diets fed on both (cholesterol and sucrose),
respectively. The results regarding insulin showed direct
proportionality with glucose. The decrease in glucose also
witnessed slight decreased amounts of insulin but the decrease
was more prominent in control groups. Although,
statistically analysis revealed significant variations in insulin
but insulin secretions are not influenced quite significantly
according to researchers point of view. Glucose
lowering properties of functional drinks containing catechins
and EGCG could not correlate with insulin but the
effects could be due to their antioxidant nature.
