Foods That Have Antihypertensive Properties
It is estimated that about one third of the world's adult population are suffering from hypertension or high blood pressure - which is the number one modifiable risk factor for cardiovascular disease and premature mortality. Studies have already revealed that consumption of green or black tea can reduce blood pressure by a small but consistent amount. Catechins, a type of phenolic compounds found abundantly in tea, were thought to contribute to its antihypertensive properties. A recent study from the University of California, Irvine found that that two catechin-type flavonoid compounds (epicatechin gallate and epigallocatechin-3-gallate) in tea help relax blood vessels by activating a specific type of ion channel protein in the blood vessel wall, named KCNQ5. This allows potassium ions to diffuse out of cells to reduce cellular excitability, said the study published in Cellular Physiology and Biochemistry. Whether the tea is consumed iced or hot, it can activate its beneficial, antihypertensive properties, said Geoffrey Abbott, PhD, a professor in the Department of Physiology and Biophysics at the UCI School of Medicine. Below are five other foods that have antihypertensive properties.
