We drink not from concentrate OJ in the morning.  As a kid in the 70's no one drank large glasses of juice, it came in a small "juice glass".   As an adult, rather than follow the serving recommendation of 8oz we  have about 1/2 glass.    This means we get almost 3 teaspoons or 11 grams of sugar with the serving.   It is still a large amount considering the overall limit is 30 grams per day. 

The article was a good reminder to pay attention to the amount of sugar in juice.
