Adage that an apple a day keeps the doctor away, says the trust is in the ears of most people. How about an apple a day for a healthy heart. A study of a number of experts from the University of Western Australia, who recently took the apples can increase the production of nitric oxide (NO) and endothelial function in heart. Nitric oxide acts on cardiovascular health by expanding the blood vessels so more blood, oxygen and nutrients from the heart can be transported through the body to improve.

While the thin layer of endothelial cells that line the inside of blood vessels. Endothelial cells reduce turbulence in blood flow and supports the distribution of blood through the body. Injury of endothelial function leads to various problems such as heart disease, coronary heart disease and heart failure.  In this study, found an apple can prevent the loss of endothelial function.
The content of flavonoids in apples increase nitric oxide production and endothelial function in heart. The higher the flavonoid content, the larger the better effect can be felt the body by only eating an apple.
