A new study from The British Journal of Nutrition has found evidence that vitamin D intake mediates the relationship between calcium and arterial stiffness in Japanese men.
Arterial stiffness is a reduction in the elasticity of the arterial wall and is an indicator of cardiovascular health, with greater arterial stiffness signifying increased risk of cardiovascular disease. It occurs primarily due to aging and arteriosclerosis.
Arterial stiffness can be assessed using pulse wave velocity (PWV). PWV uses electrodes to analyze the blood flow and the elasticity of the arteries. The large arteries around the heart are able to stretch to prevent damage when blood is ejected from the heart at high pressures.
