Different amounts of polished rice and rice bran on cholesterol metabolism in rats
Effects of polished rice and various rice bran amounts on cholesterol metabolism in rats
Abstract
Purpose of this study is to explore the rice Tainung 67 different amounts of the polished rice and rice bran fiber on the rat (Wistar strain
) Cholesterol metabolism. Male rats of about 280g, were randomly divided into eight groups, and then divided into two groups for the experiment Ⅰ and Ⅱ
. Experiment Ⅰ: corn starch as carbohydrate sources are corn starch group, polished rice polished rice instead of corn starch as a group,
The addition of 1% cholesterol plus cholesterol group and the corn starch fine white Mega cholesterol group. Part Ⅱ: fine white Mega cholesterol
Alcohol group sources its rice bran fiber, according to content into 2% rice bran, 5% rice bran, rice bran 10% and 20% rice bran
. Experiment Ⅰ and Ⅱ were removed after the chamber for four weeks blood, liver, and collect the last week of faeces for analysis
Serum cholesterol, triglyceride and total lipid, liver total cholesterol and total lipids, fecal acid and neutral sterol
. The results showed that the feed containing 1% cholesterol and promote liver total cholesterol and total lipid increased, and
increased fecal total neutral solid
Alcohol and acid steroids discharge. The milled corn starch has a lower than serum total cholesterol, and promote the total fecal bile
Acid output, but will not increase the concentration of fecal total bile acid excretion. The addition of rice bran will increase the total fecal bile acid excretion,
And also dilute the concentration of total bile acid excretion.
Therefore, the experimental results show that white rice can be effective in reducing serum total cholesterol
Alcohol and the increase in the total bile acid excretion, is
conducive to the exclusion of cholesterol, rice bran can inhibit the absorption of nutrients consumption
Of and increase in the total bile acid excretion, but the impact on cholesterol was not significant.
