>> Newman's Own Virgin Limeade

> What the heck is that doing in an otherwise (seemingly) scientific article?

Particularly since both Limeade and sugar/simple syrup are easy to make.

Syrup: 2c sugar/1c water, heat until clear, cover, cool, store in a squeeze bottle.

Limeade: 10% fresh squeezed lime juice, sugar syrup to taste but probably no more than 10%, 80% water. Depending on size & squeezer, figure maybe 1/2 oz of juice per lime. It's even easy to make single glasses.
