A High Fat Diet Attenuates The Fermentation Effects Of Resistant Starches And Fructans, Felicia Robin Goldsmith

LSU Master's Theses

In our previous studies, ingestion of prebiotics in low fat diets resulted in decreased cecal pH from 8 to about 6 and increases in short chain fatty acids indicating robust fermentation. However, in some preliminary studies this effect on fermentation was not seen when rodents were obese and/or fed a high-fat diet. This comprehensive high-fat diet study was conducted to determine which sources and combinations of prebiotics would enhance fermentation despite a high dietary fat content. The effects of prebiotics in a high-fat diet (44% energy) on pH, cecal weights, abdominal fat, and body weight were studied in mature male …
