PURPOSE: A silk peptide composition is provided to offer high molecular weight of silk peptide composition which is merely absorbed into human body and has complex function of improving hypercholesterolemia and hyperlipidemia by using silk protein. CONSTITUTION: A functional food composition is produced by decomposing silk protein and includes 10000-100000 weight-average molecular weight of silk peptides as an active ingredient. The improvement on blood lipid related diseases is improvement of total cholesterol in blood, improvement of LDL(low density lipoprotein) cholesterol in blood or improvement of triglyceride in blood. The silk protein is silk fibroin. The silk protein decomposition is performed by a decomposition method selected from a group consisting of decomposition in calcium salt solution, acidic 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.
