Bulking Agents and Losing Weight
Bulking agents and dietary fibres such as bran, linseeds or agar-agar products are indigestible herbal substances that swell up in the stomach and give you a temporary satiety feeling. These natural filling agents need a lot of water in order to swell. They make the absorption of minerals difficult and so it is advantageous to drink water that has a lot of mineral nutrients if you use bulking agents.
