Eliminating Hypertension with Coconut Oil and Exercise | The Paleo Diet

Would you believe saturated fat rich coconut oil could improve your cardiovascular health? It seems counter intuitive based upon common impressions of saturated fat being detrimental to our vascular system,1 however a new study indicates that the combination of coconut oil supplementation and exercise has been linked to reduced body weight, reduced blood pressure, improved baroreflex sensitivity, decreased lipid peroxidation, and reduced superoxide levels.2 These findings have the ability to help over 67 million people struggling with hypertension, who have blood pressure levels greater than 120/80 mm Hg3, increasing their risk of heart attacks, heart disease, strokes, vision issues and kidney disease.

The researchers used baroreflex sensitivity, a tool for the assessment of autonomic control of the cardiovascular system, to assess the impact coconut oil and exercise had on their subjects’ health, independently and together. Baroreceptors, located in the carotid sinus and in the aortic arch, adjust the pressure changes in the arterial wall to maintain homeostasis with parasympathetic responses.4 Cardiovascular diseases are often accompanied by an impairment of baroreflex mechanisms, and a reduction in the baroreflex control of heart rate has been reported in hypertension, coronary artery disease, myocardial infarction, and heart failure.5

Further, elevated blood pressure corresponds to both the release of free fatty acids into the blood and muscle fibers6 as well as to oxidative stress, an imbalance between the production of free radicals and the ability of the body to counteract or detoxify their harmful effects through neutralization by antioxidants.7 These factors promote inflammatory processes such as atherosclerosis8 and lead to heart and blood vessel disorders, atherosclerosis, heart failure, heart attack and inflammatory diseases. Coconut oil and exercise showed the combination of the two led to a decrease in oxidative stress, which correlates with better endothelial-dependent relaxation of the aorta and significantly lower (20 mm Hg) blood pressure.9

How can this new research help you?

Hunter-gatherers avoided the many modern diseases that plague us today. The Paleo lifestyle, including the dietary and exercise prescriptions, can assist you in lowering blood pressures to healthy levels, especially with the regular addition of coconut oil into your dietary regime.

Dietary changes are usually prescribed prior to medication as a method to lower blood pressure levels into a safe range. The Paleo Diet eliminates processed foods, salt, and is high in anti-inflammatory Omega-3 fatty acids.10

Numerous studies provide clear evidence of the positive effects of exercise on lowering blood pressure values to a healthy range.11 People who are inactive typically have higher blood pressure than those who exercise regularly, and inactivity is a major risk factor for cardiovascular disease.12

It is possible to reduce your risk for hypertension with lifestyle choices alone. Blood pressure tends to rise with age, so it’s important to monitor it annually with your doctor. The long-term health benefits by making long-lasting lifestyle changes by adopting a Paleo Diet will follow.

Blood Pressure | The Paleo Diet

A number of Paleo followers regularly send me emails regarding their low blood pressure levels that result from eating a low-carb, Paleo Diet. Specifically, people seem to worry that they may suffer from negative health consequences if their blood pressure drops too low.

Naturally, The Paleo Diet promotes low blood pressure in the human body by reducing cortisol, the stress hormone, and keeping sodium intake to a minimum by replacing processed, salt-laden foods with real, whole foods. Eating a well-balanced, healthy diet does not induce orthostatic hypertension, or consistently lower normal blood pressure levels.

Tips to help you maintain a healthy blood pressure level while following The Paleo Diet:

Stay Hydrated

    • Make sure to consume adequate amounts of water throughout the day. Keeping the body hydrated helps the heart more easily pump blood through the blood vessels. If you are working or spending a large amount of time outdoors, grab a water bottle on the way out.

Increase Sodium Intake

    • Moderation is key, but adding a small amount of natural sea salt as a seasoning to your meals may be beneficial, especially if you are consuming a strict salt-free Paleo diet.

Maintain an Electrolyte Balance

Cut It Out

  • Beet juice and licorice have been linked to raising blood pressure in individuals with orthostatic hypertension.

Case in point: The primary source of blood pressure problems is more often than not due to increased inflammation in the arterial linings from following a SAD diet (Standard American Diet). Consuming a nutrient-dense Paleo Diet should stabilize your blood pressure levels over time.
