Oh, I used to worry if cold coconut water would give me a cold or cough! But it's actually very safe and full of nutrients, just make sure to drink it fresh in the morning.
I panicked when someone told me coconut water makes the baby's head too big! But it's totally safe and actually helped with my severe acidity, so don't worry.
It is superb for hydration, especially after my 30-minute doctor-approved evening walks. It replenishes electrolytes naturally without any artificial sugar.
Nariyal pani is amazing and cheap compared to expensive health drinks. I drank it daily and it saved me from expensive IV hydration costs at the hospital.
