The Greenthinkers food and drink tip of the day today is Whole Kids Organic Lemonade.

As we try to squeeze enjoyment from the last remaining moments of summer, why not stop for a cool refreshing glass of lemonade - a summer classic. And hey, why not go organic at the same time? Whole Kids Organic Lemonade from Whole Foods Market is an all-natural concoction that uses grape juice instead of sugar for sweetness. It was recently named Real Simple’s 2nd best store bought lemonade.

Plus, new research by the University of Wisconsin shows that lemonade is an effective way for the kidney-stone-prone to slow the development of new stones.

Pucker up.
