We evaluated the effect of high-fiber cereals on short-term food intake. At 0730, 14 subjects ingested one of five cereals, plus milk and orange juice. At 1100 they were presented with a buffet lunch. There was a significant inverse correlation between fiber content of the cereals and energy intake at lunch. In a second study subjects ingested a very-high-fiber (VHF) cereal or a very-low-fiber (VLF) cereal. Fewer kcalories were ingested at lunch after ingestion of the VHF cereal than after ingestion of the VLF cereal. The degree of colonic microbial fermentation of the various cereals was evaluated by breath-hydrogen analysis. The higher-fiber cereals resulted in greater hydrogen production; however, this may not influence energy intake. The results of questionnaires that asked about hunger indicated that food intake can be reduced without the perception of feeling less hungry. Thus, we found that cereals containing relatively large quantities of dietary fiber may decrease short-term food intake.
我们评估了高纤维谷物对短期食物摄入量的影响。早上7点30分，14名受试者食用了五种谷物中的一种，外加牛奶和橙汁。上午11点时，为他们提供了自助午餐。谷物的纤维含量与午餐时的能量摄入量之间存在显著的负相关。在第二项研究中，受试者食用了高纤维（VHF）谷物或低纤维（VLF）谷物。与食用低纤维谷物后相比，食用高纤维谷物后午餐摄入的卡路里更少。通过呼气氢分析评估了各种谷物的结肠微生物发酵程度。纤维含量较高的谷物会产生更多的氢气；然而，这可能不会影响能量摄入。关于饥饿感的问卷调查结果表明，在没有感觉更饥饿的情况下，食物摄入量可以减少。因此，我们发现含有相对大量膳食纤维的谷物可能会减少短期食物摄入量。
