Healthcare
function of konjac |
Konjac is a kind of food
with low heat energy, low protein, low vitamin, and high
dietary fiber. High dietary fiber is the effective nutritious
ingredient in konjac. Konjac extracted powder is the
concentrate of the effective nutritious ingredient, it is
manufactured by treating the corm of konjac with a physical
method and konjac glucomannan is the most effective ingredient
of konjac extracted powder, featured as soluble
semi-cellulose. By adjustment action for nutrition imbalance,
the nutrition function and healthcare function of konjac is
produced. |
| Ⅰ Prevention and
Treatment for Constipation |
| Constipation
should be mainly prevented by increasing the content of
dietary fiber in normal diet, and coarse food grain,
vegetable, fruit and konjac extracted powder are the rich
source of dietary fiber. Konjac fiber has high water-binding
capacity, its volume can be expanded for 80~100times through
water-absorbing, so wet weight of dung and water content is
increased after the meal. Moreover, when konjac fiber is
decomposed by colon bacteria ， short-chain fatty acid is
produced to stimulate intestine wriggling ， and the interval
of dung defecating and duration of each dung defecating are
thereby shortened. |
| Dietary fiber
plays a great role in prevention of cancer of the intestines.
The carcinogen in intestine can be diluted by dietary fiber,
and the passing time through intestine can be shortened, the
duration of the irritation caused by poison to intestine is
reduced to improve the excretion of the poison from intestine,
the irritation on intestine caused by carcinogen is so
reduced. |
| II Adjustment for Lipoid
Metabolism |
| When soluble
dietary fiber is combined with cholic acid in intestine ，the
excretion of cholic acid is increased, the synthesis of cholic
acid in vivo is improved, and cholesterol level in blood is
therefore reduced, and the gall-bladder stone accumulated
during excretion in biliary tract and the potential
carcinogenesis arising from cholic acid metabolite can also be
reduced. |
| It has been
reported in internal and external market that konjac shows
evident effect in blood lipoids descending ， both cholesterol
level and triglyceride level can be reduced and it has been
proved that blood lipoids level will no longer be reduced
continuously in case of the normal blood lipoids is attained,
the adjustment function for lipoid metabolism and prevention
function for hyperlipidemia are exhibited accordingly. |
| III Improvement for Sugar
Metabolism |
| Diet control
is the critical measure for treatment of diabetes, dietary
fiber is unable to be digested and absorbed and there is no
heat energy generated with the sensitivity of stomach fullness
， the absorption of glucose can also be reduced and postponed,
dietary fiber is the good adjuvant drug for diabetes. Some
studies show that soluble fiber exerts an evident action on
sugar metabolism improving. |
| Ⅳ Weight-losing
Function |
| The filling
action of dietary fiber in stomach can enhance the sensitivity
of stomach fullness, and reduce the absorption of
heat-generating nutrient. Adding a certain amount of konjac or
other soluble fiber in normal diet, obesity preventing and
gentle weight losing can be expected. At the present, some
weight-losing foods or healthcare foods mixed with
konjac-extracted powder have been introduced in the market. |
