Banana, the Best Anti Hypertension Functional Fruit, According to Studies

By Kyle J. Norton

Scientists may have found an inexpensive whole fruit for the prevention and treatment of hypertension with no side effects, some studies found.

Banana is the common name of a genus of tropical herbaceous plants. It can grow from 3 to 9 m and belongs to the family of the lily and the orchid. 

Hypertension is a medical condition characterized by the abnormally high blood pressure. one of the preventable risk factor of heart disease associated with the cluster of metabolic syndrome.

In other words, high blood pressure means the raising the pressure in your heart. the condition can be acute or chronic.

Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. 

Chronic high blood pressure epidemiologically can damage the arteries and causes blood clots to form in the arteries, blocking the blood flow and contributing to the onset of cardiovascular and neuro diseases.

Although certain chronic conditions such as kidney disease are found to associate with chronic hypertension which can only be treated by addressing the causable condition, the syndrome in the Western world are mostly as a result of unhealthy diet and obesity.

According to a joint study led by the Tecnológico de Monterrey, that examined the effects of 

Western and Modern Mexican dietary patterns and the incident hypertension in Mexican women, the comparison of participants who followed the diet with loaded heavily with vegetables, fruits and legumes and who follow the Western and Modern Mexican dietary patterns loaded heavily with processed meats, fast foods, and red meat; and finally the third component was loaded heavily with corn tortillas, hot peppers, and sodas suggested that 

* The multivariable-adjusted odds of hypertension in the highest quartile of the W pattern were 24% higher than the odds for individuals in the lowest quartile.

 * Women in the highest quartile of the MM pattern had 15% higher odds than women in the lowest quartile.

* And The Fruits & Vegetables (FV) pattern was not significantly associated with hypertension.

These results strongly indicated high blood pressure can be prevented by following a healthy diet with high fruits and vegetables, whole grain and low saturated and trans fat, red meat and processed foods. 

On finding a natural chemical compound or whole food for the prevention and treatment of hypertension, researchers evaluate the corosolic acid (CRA) antihypertensive activity, a constituent of banana leaves.

The experiment included Six-week-old male SHR-cp rats, an animal model of metabolic syndrome were fed a high-fat diet containing 0.072% CRA for 14 weeks. 

Treatment with CRA lowered blood pressure, which was elevated in control animals, by 10% after 8 weeks, and serum free fatty acids by 21% after 2 weeks.

Oxidative stress markers thiobarbituric acid-reactive substances and 8-hydroxydeoxyguanosine in the tested animal were also decreased by 27% and 59%, respectively, after 2 weeks.

Furthermore, CRA treatment also reduced the levels of myeloperoxidase markers, 3-nitrotyrosine, and 3-chlorotyrosine, by 38% and 39%, respectively, after 10 weeks, and decreased the levels of high sensitivity C-reactive protein, markers of inflammation, after 6 weeks.

The presence of a marker of inflammation is the indication of inflammation.

These results clearly suggested that CRA ameliorate hypertension, and oxidative stress caused by the inflammation in SHR-cp rats.

Dr. Yamaguchi Y, the lead scientist said, "CRA can be beneficial for preventing atherosclerosis-related diseases that are an increasing health care problem worldwide".

Moreover, In a human study to test the effect of banana on cold stress-induced hypertension, peak expiratory flow rate and plasma ACE activity, researchers showed that

*Banana treatment reduced the systolic blood pressure (P < 0.005), diastolic blood pressure (P < 0.025) and mean arterial blood pressure (P < 0.005) during cold stress in healthy volunteers compared to controls.

* There was no significant changes in heart rate and peak expiratory flow rate but only significant decrease in plasma angiotensin-converting enzyme activity after banana treatment.

Levels of plasma angiotensin-converting enzyme are high in patients with hypertension.

Dr. Sarkar C, the lead scientist said' "Banana decreased the rise of systolic blood pressure and diastolic blood pressure in healthy volunteers subjected to cold stress test without much effect on heart rate and peak expiratory flow rate".

Taken altogether, banana may be considered a functional fruit for the prevention and treatment of hypertension with no side effects.
