Dietary cholesterol induced changes in serum lipoproteins in healthy females

We studied the effect of high cholesterol fat breakfast containing approximately 527 mg cholesterol and 33 gm fat given for seven days in 10 healthy females of young age (18 to 21 years) and in healthy older females of age group (48 to 60 years). Serum total cholesterol and low density lipoprotein did not alter significantly after feeding and after withdrawal of high cholesterol fat breakfast. Serum high density lipoprotein increased significantly in young females after feeding and further increased after withdrawal for seven days, while in older females no appreciable change occurred. Serum triglyceride showed a significant decline in young persons after feeding but gradually increased after withdrawal while in older females no significant change occurred.
