Coconut oil is one of the few foods that can be classified as a "superfood".
Its unique combination of fatty acids can have profound positive effects on health, including fat loss, better brain function and many other remarkable benefits.
Researchers working at the Federal University of Paraiba in Brazil set out to test the hypothesis that a combination of daily coconut oil intake and exercise training would restore baroreflex sensitivity and reduce oxidative stress, resulting in reduction in blood pressure.
Their experiments were performed in spontaneously hypertensive rats. They found that both coconut oil and exercise training were able to reduce weight gain compared to rats that were given saline and were not exposed to the exercise training protocol along the five weeks of study.
Either coconut oil supplementation or exercise training was shown to reduce blood pressure. However, only combined coconut oil and exercise training were able to bring the pressure back to normotensive values.
The reduction in blood pressure caused by the combination of coconut oil supplementation and exercise training might be explained by the improvement of the reduced baroreflex sensitivity and by the reduction in oxidative stress in the serum, heart and aorta.
"This is an important finding as coconut oil is currently being considered a popular superfood and it is being consumed by athletes and the general population who seek a healthy life style," explained Dr Valdir de Andrade Braga, co-author of the study.
"The possibility of using coconut oil as an adjuvant to treat hypertension adds to the long list of benefits associated with its consumption. Our next step is to start some clinical trials in order to verify whether we can reproduce those findings in hypertensive human patients".
Nearly 139 million Indians were suffering from high blood pressure (BP) at the end of 2008 — 14% of the global burden of uncontrolled hypertension. From 1980-2008, the number of Indians suffering from high BP rose by 87 million, while the percentage of population suffering from the ailment rose from 21% to 26%.
The latest data of the Global Burden of Diseases, Injuries and Risk Factors study, published in the British medical journal The Lancet shows that while the average BP of humans declined globally, it actually increased among both men and women in India.
The average BP went down by 2.7mm mercury among women globally, while increasing by 2.4mm mercury in India. In men, it decreased by 2.3 mm mercury globally in the past three decades whereas in India it went up by 2.2 mm mercury. At present, hypertension is directly responsible for 57% of deaths due to stroke and 24% of deaths caused by heart attack.
High BP is the leading risk factor for cardiovascular disease mortality, causing more than 7 million deaths every year worldwide. The study says that though prevalence of uncontrolled hypertension dipped from 33% in 1980 to 29% in 2008 in men and from 29% to 25% in women, the actual number of people with uncontrolled hypertension increased from 605 million in 1980 to 978 million in 2008.
