Abstract

Whey is a rich natural source of peptides and amino acids. It has been reported in numerous studies that biological active peptides isolated from cow’s milk whey may affect blood pressure regulation. Studies on animals and humans have shown that α-lactalbumin and β-lactoglobulin obtained from enzymatically hydrolysed whey inhibit angiotensin converting enzyme (ACE), while lactorphins lower blood pressure by normalizing endothelial function or by opioid receptors dependent mechanism. Whey proteins or their bioactive fragments decrease total cholesterol, LDL fraction and triglycerides, thus reducing the risk factors of cardiovascular diseases.The aim of this review is to discuss the effects of whey proteins on the mechanisms of blood pressure regulation.
