Enriched QUARTET® Hen Eggs and Cardiovascular Function

Effect of Enriched QUARTET® Hen Eggs on Cardiovascular Function in Cardiovascular Patients and Healthy Individuals

Role of oxidative stress in the development of cardiovascular diseases is well known and extensively investigated, because of its direct effects on vascular function, but also on the activation of the immune response. Thus, food products that could increase the antioxidant capacity of the vascular system would also act protective against cardiovascular diseases. However, we lack systematic clinical and pre-clinical research with food products instead of food supplements, which would result in consistent and repeatable results. Many studies have proven the effectiveness of n-3 polyunsaturated fatty acids (n-3 PUFA) in improvement of endothelial function, improvement of elasticity of the vascular wall and the anti-inflammatory effects in patients with chronic diseases, such as metabolic syndrome, if they are taken as an pharmacological preparation. Our research group recently reported that favorable anti-inflammatory properties of n-3 PUFA enriched hen eggs potentially contribute to the improvement of microvascular endothelium-dependent vasodilation in healthy individuals. In addition, this study aimed to determine the effect of QUARTET® hen eggs (enriched in n-3 PUFA, selenium, vitamin E and lutein; QUARTET No. 012743696, 2014.) consumption on cardiovascular function in both healthy individuals and cardiovascular patients.
