PURPOSE: A silk peptide composition having diabetes improving functions is provided to improve diabetes using silk protein and offer a high molecular weight of silk peptide composition which is merely absorbed into the human body. CONSTITUTION: A functional food composition is produced by decomposition of protein and includes an average molecular weight of 10000-100000 of silk protein as an active ingredient. The silk protein is silk sericin or silk fibroin. The silk protein is silk fibroin. The silk protein decomposition is performed by a decomposition method selected from a group consisting of the decomposition of calcium salt solution, acid hydrolysis, decomposition by a mixture solution of calcium salt and ethanol and a combination thereof. The calcium salt is calcium chloride. The calcium salt removal is selected from a method consisting of dialysis, ultrafiltration, gel chromatography, electric desalting and a combination thereof.
