In 40-week-old male wister rats reared for one week with food containing 10%, 5%, and 2% cellulose as dietary fiber, suppression of lipid synthesis system was seen in the gene expression of the liver. Although , in regard to lipid levels in liver, the total cholesterol level was seen to significantly increase by increasing the intake of cellulose. Also, a significant variation in the intestinal flora due to the variation of dietary fiber intake was detected. The observation of the change in gastrointestinal gene expression due to the amount of cellulose intake is the report which shows that cellulose that is not absorbed into the body has a function to indirectly control the gene expression in the body.
