Since 2008, Japan Wakayama Prefectural Medical University and the National Wakayama High School have jointly conducted research to comprehensively analyze the health effects of peaches. The researchers focused on a hormone called angiotensin. Angiotensin has been shown to be one of the major causes of hypertension and arteriosclerosis. When the pressure of life is high, the diet is irregular, and there is a lack of sleep, the body will secrete this hormone in large quantities, resulting in vasoconstriction and elevated blood pressure. The study, published in the British Journal of Food Chemistry, found that the amount of angiotensin in the body decreased after proper intake of peaches. In vitro studies have also found that angiotensin activity is significantly inhibited after the addition of peach extract to tissue cells.
Yu Dugong Yang, a researcher and associate professor of cell biology, speculated that the polyphenols and other substances rich in peaches may directly affect the secretion and activity of hormones, thereby reducing blood pressure and protecting cardiovascular and cerebrovascular diseases. In the future, they will further analyze the relationship between the incidence of chronic diseases such as heart disease and eating habits, and help people easily “protect their hearts”.
