For some reason Japanese people love them some excessive amounts of vitamin C. Go to any convenience store or supermarket and your sure to find competing brands of drinks all loaded with the recommended daily intake of the stuff several times over.
But really, how many of us know off-hand what the daily recommended intake is? That’s why back in 2009 the Japan Soft Drink Association (JSDA) came up with a new labeling system that measures the amount of vitamin C added in units of lemons. I’m not sure how that actually makes it any clearer, but at least its something.
However, in the process it seems they have inadvertently created a formula that shows how a single lemon contains an infinite amount vitamin C.
