Dr. Gavin Munsfield, protagonist in JOURNEY TO JUDAH and RESTORED HEARTS, recommends drinking coconut water which provides an excellent blend of electrolytes, re-hydrating the body better than sports drinks.
Coconuts are plentiful in Chennai, setting for my Born for India trilogy. While visiting there, we would pull up to a coconut stand (a small open hut on the side of the road). Yep, coconut stands are India's version of "Sonic." The Indian merchant whacks a hole in the top of the coconut with his machete, sticks a straw in, and wah-lah, drink to go! And for a mere .75 US at that!
Rumor has it that coconut water was used as a plasma substitute in WWII. Indeed, coconut water seems to benefit the body, providing potassium and other essential nutrients, warding off fatigue, and providing a higher level of protein than cow's milk with less fat and fewer calories. It also contains lauric acid, which is present in human mother's milk. Now I know why the Indians kept handing us coconut water during our first trip to Madras 14 years ago!
Pass the coconut water, please!
