Abstract
The study was carried out to determine the
effect of roasted groundnut (Arachis hypogea) on obesity and cholesterol level
using rats. Fifteen albino rats of weight in the ranges 70 grams and 82 grams
were grouped into five and fed with RAA (100% commercial rat fed), RAB (60% rat
feed: 40% groundnut feed), RAC (50% rat feed: 50% groundnut feed), RAD (40% rat
feed: 60% groundnut feed), RAE (100% groundnut feed) separately and monitored
for 28 days (4 weeks) with weekly assessment of weights using aid of a toploading
weighing balance (Netler, England), and an improvised “ratbag” and total
cholesterol determination were measured weekly using a standard CHOD-PAD single
reagent test kit and spectrophotometer. Statistical analysis was also carried
out using IBM Statistical Product of Service Solution (SPSS) Version 23.0.
Results of proximate analysis ofthe rat diets showed significant differences
(p<0.05) between the commercial feed and the groundnut supplemented diets.
Protein content was the highest in RAE (24.63%) feed diet and lowest (18.96%)
in RAA feed diet. Diet RAA had the lowest fat content (9.18%) whereas RAE had
the highest fat content (38.01%). Diet RAE had the lowest cruder fiber content
(1.52%) whereas RAA had the highest crude fiber (9.45%). Diet RAE had the
lowest ash content (4.12%) whereas RAA had the lowest ash content (5.19%). Diet
RAE had the lowest moisture content (5.82%) where RAA had the lowest moisture
content (10.97%), for carbohydrates contents, RAE had the lowest carbohydrate
content (25.90%) whereas RAA had the highest carbohydrate content (46.25%).
Results of the mineral content of the rat diets showed significant differences
(p<0.05) between the commercial feed and the groundnut supplemented diets
while sodium had no significant differences (p>0.05). Diet RAA had the
lowest mineral content in Calcium (86.67mg/100g), Sodium (30.60mg/100g) and
Phosphorus (44.87mg/100g) whereas RAE had the highest mineral content in
Calcium (201.03mg/100g), Sodium (31.33mg/100g) and Phosphorus (94.83mg/100g).
Results of the Vitamin contents of the rat diets showed a significant
difference (p<0.05). Diet RAE had the lowest Vitamin content in Vitamin A
(5.167mg/100g), Vitamin Bi (0.047mg/100g), and Vitamin E (O.OOmg/lOOg) whereas
RAA had the highest in Vitamin A (113.280mg/l 00g), Vitamin Bi (0.147mg/100g),
and Vitamin E content (9.347mg/100g). Results of the antinutrients content of
the rat diets showed significant differences (p<0.05) between the commercial
feed and the groundnut supplemented diets. Diet RAE had the lowest phytate
content 0.31% whereas RAA had the highest 0.47%. Diet RAA had the lowest
hydrogen cyanide (HCN) content 0.91mg/kg whereas RAE had the highest 1.29mg/kg.
Changes in the cholesterol levels and weight gain ofthe rat had a significant difference
(p<0.05). Results of cholesterol level shows that it decreased significantly
in the rats fed with groundnut-supplemented feed and increased in the controls
fed with commercial feed. Cholesterol level was between 102.83mg/dl to
121.33mg/dl (RAA) in the content ofthe commercial feed but decreased from
108.17mg/dl down to 92.67mg/dl (RAE) in the fourth week period ofstudy in the
groundnut feed. There was a significant differences (p<0.05) in weight gain.
The percentage weight increase was 3.17% in the control rats (RAA) in the
fourth week but the weight decreased to 1.15% in the fourth week ofthe
groundnut rats (RAE). Based on the findings, it was observed that the
groundnut-supplemented feeds reduced both blood cholesterol and overweight in
the rats. This shows that groundnut could be used to control weight and blood
cholesterol.
