But is coconut water good for you, or is it just another passing trend? Coconut water is about 95% water, making it inherently hydrating. The results showed that coconut water was linked to improved outcomes compared to the placebo, including that more patients in the coconut water group achieved remission and showed significant symptom improvement. Coconut water may also not be the best choice for those who need to limit their calorie intake, as it contains more calories than plain water. Additionally, people with nut allergies should consult a healthcare provider before consuming coconut water, as some may have sensitivities to coconut.
