We all know that coconut water is healthy and provides a number of benefits which promote overall health. However, as with everything else, it should be consumed in moderation because excessive intake can lead to some serious complications.
A recent study, called Death by Coconut, led by Dr. Justin Hakimian and his team, examined the case of a 42-year old man who experienced abnormal heart rhythm and frequent episodes of fainting after drinking coconut water. The man was at a tennis game when he consumed a bottle of coconut water. He was taken to hospital after losing consciousness, which the doctors ascribed to low heart rate and hypotension.
Coconut water is rich in potassium, which is why doctors found increased potassium levels in the patient’s blood. Even though we know that our body needs this mineral for proper function, excessive amounts of it can also trigger some health issues including arrhythmias and ventricular fibrillation, both of which can be fatal if left untreated.
According to the Institute of Medicine, the recommended daily potassium requirements equal 4,700mg for adults. However, scientists are still uncertain as to what’s the maximum potassium amount the human body can metabolize. Potassium levels in the blood can rise as a result of reduced excretion and excess potassium intake.
Other contributing factors that lead to increased potassium levels include:
- breakdown of red blood cells (hemolysis)
- breakdown of muscle tissue (rhabdomyolysis)
- Addison’s disease (adrenal failure)
- uncontrolled diabetes
- burns and trauma
- medications such as beta blockers, ACE inhibitors, and some antibiotics such as penicillin
- kidney disease
The subject of the above-mentioned study experienced increased potassium levels due to muscle tissue breakdown, which was a result of muscle exertion, vigorous exercise and working out in hot weather. The man consumed 5,500mg of potassium through coconut water, which led to his hospitalization, according to doctors. This condition can also result in kidney damage.
Fortunately, the patient’s condition improved after he was given a pacemaker – his heart function normalized along with his potassium levels. Also, his kidneys and muscles started functioning normally.
The high potassium level in coconut water and the dangers of it have been examined by other studies as well.
Health experts strongly advise that people with kidney disease and heart problems avoid drinking coconut water, especially after strenuous exercise, when the body’s electrolyte levels drop significantly. On the other hand, coconut water is low in electrolytes and cannot properly hydrate your body in these conditions.
Coconut water is healthy and should be consumed but in moderation. If you want to take advantage of its benefits and avoid the health risk limit your daily intake to a couple of servings and you’ll be just fine.
