Mailport: July 2010
In reference to your "Bottoms Up" article (June 2010) on hydration choices: As a penny-pinching, label-reading sailor, I buy Gatorade in the powder form. It costs about $1 per gallon (add your own water) and does not contain high-fructose corn syrup.
Also, I want to mention that when drinking real, green-coconut water, caution is required: I can attest to its efficacy as a natural laxative! We encountered this years ago while cruising the Bahamas. No scientific testing was done, but our conclusion was confirmed by the locals.
More on hydration
Your June 2010 article on hydration missed a powdered product, one which is easy to buy and easy to carry. The version with sugar is called Emergen-C and its low-sugar version is Emergen-C Lite.
Gatorade works well for many, but not for those of us who are circumferentially challenged and cannot afford the calories.
Emergen-C Lite has the necessary electrolytes, potassium, and sodium to stave off de-hydration, plus a number of other ingredients such as folic acid. The flavored powder comes in small envelopes and can be just added to water, though I prefer to add it to lemonade. It is available in many health food stores.
One time in the Bahamas, I allowed myself to get very dehydrated, and after we docked, I drank a lot of water. My body reacted, including an irregular heart beat. The problem, I found, did not occur on dehydration, but rather when I attempted to re-hydrate without electrolytes and unbalanced my body chemistry.
