Properties a study published in the European Journal of Clinical Nutrition, the combination of milk proteins could reduce arterial stiffness and thus, the episodes of atherosclerosis. These benefits would bring the milk would be very useful for improving cardiovascular health.
Research conducted at the University of Helsinki, established the benefits of milk proteins may contribute to cardiovascular health, through a combination of proteins, such as isoleucyl-proline-proline (IPP) and valyl-proline-proline (VPP) which would be responsible for reducing arterial stiffness and improve endothelial cell function found in the blood vessels.
Description of the study
* the research was conducted on a sample of 89 people suffering from hypertension. He randomly chose a group that was provided with a low dose of tripeptides (5 mg / day) for 12 weeks followed by a high dose (50 mg / day) for 12 weeks. The other group received a placebo.
Results
* At end of study measured arterial stiffness through an augmentation index (AIX). It had decreased by 1.53% in the group receiving the combination of tripeptides. While in the control group had increased arterial stiffness.
* In both groups there were no differences in endothelial function.
Conclusions
* the researchers note that the action of these peptides may be due to inhibition that they exercise on the angiotensin converting enzyme (ACE).
* This would prevent the conversion of angiotensin I to angiotensin II, which has a high vasoconstrictor effect. These benefits provide the combination of protein, not only improve blood flow but also blood pressure, reducing the risk of cardiovascular disease.
