瓜尔豆胶
The use of guar gum as an ingredient in non-prescription diet aids was officially banned in the early 1990s by the FDA. The guar gum would bind with liquids in the stomach and swell, causing a feeling of satisfying fullness. However, this mass of swollen guar gum would also cause dangerous intestinal and duodenal blockages. Guar gum was declared unsafe and ineffective for use as a non-prescription diet aid, although it is still used in small amounts as a food thickener and binder. |
