| Outline of Final Research Achievements |
The aim of this study is to examine if dietary glycogenic amino acid control on fructose preference in a two-dish preference test from maltose diet (Mal) and sucrose diet (Suc). Rats fed low protein diet preferred Suc to Mal in the short term at days 2.5, and then changed their preference to Mal through term of experiment. Rats fed glutamic acid (Glu) or aspartic acid (Asp) - additional diets changed and expressed a preference from Suc to Mal at days 4.4 and 6.2.
Thus, rats fed, Glu or Asp deficient 20% protein diets changed and expressed a preference from Suc to Mal was at days 1.6 or 1.9, whereas control was at day 7.The same effect was not observed when it was substituted with the other glycogenic amino acids. These results suggest that the regulation of fructose preference is correlated by dietary Asp and Glu.
