Free radicals are unstable molecules that are produced by the natural metabolic functions of the body. But an overload of these reactive oxygen species can damage the body cells and develop oxidative stress. A body under high oxidative stress is prone to various diseases such as cancer, atherosclerosis and diabetes. .So how can you prevent free radical accumulation?

Antioxidants are substances that prevent the buildup of free radicals in the body. Research suggests that coconut water contains high levels of antioxidants that can help prevent oxidative stress. Coconut water contains ascorbic acid, caffeic acid and several types of phenolic compounds which are responsible for scavenging off these free radicals. A preclinical study demonstrated that the antioxidants present in coconut water efficiently reduced blood pressure, blood glucose, triglycerides and fatty acid levels in the body while the natural antioxidant activity was significantly increased.

They are usually characterized by severe abdominal pain and burning sensation while passing urine. A study done on animal models for a period of seven weeks revealed that consumption of coconut water reduces the formation of kidney stones and also helps reduce the number of crystals formed in urine. This research indicates that coconut water can be used as a natural agent for the treatment of kidney stones.

Coconut water is fat-free and is often believed to be a magic potion to stay fit and healthy. However, excess of anything is bad. Although coconut water has a lot of health benefits, it has its ill effects and disadvantages too.

  • May cause hyperkalemia 
    High potassium levels can cause a condition called hyperkalemia. A delicate balance of potassium is needed in the body to maintain a healthy working heart and muscles. An excessive amount of coconut water intake can cause a spike in the potassium levels in the body which can lead to dangerous and deadly changes in the rhythm of the heart. If this condition is not treated, it could even lead to death.
  • May lower the blood pressure
    As a hypotensive (lowers blood pressure), coconut water is beneficial for people suffering from high blood pressure. However, people who already have a problem of low blood pressure should avoid coconut water, as it may further lower their blood pressure levels.
