Abstract :
Obesity is a condition of excessive fat accumulation in the body that can
interfere with health. Intake of nutrients from fat sources can affect total
cholesterol levels. Excess cholesterol levels can cause cardiovascular disease.
One of the prevention efforts is by non-pharmacological therapy in the form of
purple sweet potato. Purple sweet potato contains flavonoids which inhibit the
absorption of cholesterol in the digestive tract. The purpose of this study was to
determine the effect of giving purple sweet potato flour to changes in total
cholesterol levels of male white rats wistar strain obesity model. This type of
research is True Experimental with Pre-Posttest With Control Group Design. The
sample used in this study consisted of 30 rats divided into three groups, namely
negative control (K-) given Ratbio feed, while positive control (K+) and treatment
(P) were given an induction diet high in fat and 66% fructose for 56 days. . The
treatment group was given the intervention of purple sweet potato flour dissolved
in 10 ml of distilled water for 6 days. The mean pretest total cholesterol level in
the group (K-) = 78 mg/dl, (K+) = 57 mg/dl, (P) = 62 mg/dl. The mean posttest
total cholesterol level in the group (K-) = 74 mg/dl, (K+) = 71.86 mg/dl, (P) =
68.86 mg/dl. There were differences in total cholesterol levels before and after the
purple sweet potato flour intervention in the K+ group (p= 0.028) and there was
a significant difference (p = 0.015).
