In vivo Iron Availability and Profile Lipid Composition in Anemic Rats Fed on Diets with Black Rice Bran Extract

Description

Iron is an essential nutrient with limited
bioavailability. Nutritional anemia caused mainly by iron deficiency
is the most recognized nutritional problem in both countries as well
as affluent societies. Rice (Oryza sativa L.) has become the most
important cereal crop for the improvement of human health due to the
starch, protein, oil, and the majority of micronutrients, particularly in
Asian countries. In this study, the iron availability and profile lipid
were evaluated for the extracts from Cibeusi varieties (black rices) of
ancient rice brans.
Results: The quality of K, B, R, E diets groups shows the same
effect on the growth of rats. Hematocrit and MCHC levels of rats fed
K, B, R and E diets were not significantly (P<0.05). MCV and MCH
levels of rats K, B, R were significantly (P<0.05) with E groups but
rats K, B, R were not significantly (P<0.05). The iron content in the
serum of rats fed with K, B, R and E diets were not significantly
(P<0.05). The highest level of iron in the serum was founded in the B
group. The iron content in the liver of rats fed with K, B, R and E
diets were not significantly (P<0.05). The highest level of iron in the
liver was founded in the R group. HDL cholesterol levels were
significantly (P<0.05) between rats of fed B, E with K, R, but K and
R were not significantly (P<0.05). LDL cholesterol levels of rats fed
K and E significantly (P<0.05) with B and R.
Conclusions: the bran of pigmented rice varieties has, with some
exceptions, greater antioxidant and free-radical scavenging activities.
The results also show that pigmented rice extracts acted as prooxidants
in the lipid peroxidation assay, possibly by mechanisms
described for the pro-oxidant activities of tocopherol and ascorbic.
Pigmented rice bran extracts more effectively increases iron stores
and reduces the prevalence of iron deficiency.
