Most of the fibres contained in hi-firbre food are thawless; However, Polydextrose can easily be dissolved by water and has the following health care functions that common thawless fibres do not have:

1. To adjust the metabolizing of fat Clinic experiments show that a proper sum of soluble fibre in small intestines can produce a layer of membrane, which can prevent the absorbing of fat in the alimentary canal and accelerate the excretion of lipoid compounds, so that it is able to adjust the sum of fat in blood and prevent blood vessel disease in heart and brain.

2. To improve the metabolizing of glucide Soluble fibres can reduce the absorption of glucide, while they themselves can not be absorbed. Low-sugar and low-heat food is helpful to diabetics.

3. To cure constipation and prevent diarrhea Soluble fibres can preserve moisture, accelerate the peristalsis of intestines, soften and enlarge dejecta, and in the end expedite excretion. Obvious curative effect can be seen after 3 days' use.

4. To enhance immunity ability Since soluble fibres are good at preserving moisture, they can dilute the consistence of the harmful things in intestines and expedite excretion. Clinic practice proves that soluble fibres can prevent and cure cancer, particularly colon cancer, in some ways.
