Fruit juices have a lot of sugar, hence some food police condemn them.

All a lot of nonsense. Sugar is bad for the teeth only if they remain coated for long periods of time.

I like the statement on a tote bag given out to those who donate to arthritis studies.

Take control
Keep moving
EAT WELL (caps mine)
Enjoy life

I take the third recommendation to mean don't eschew any food you like; but be informed about them.

(Too much exercise, too much almost anything can kill you; be moderate* and enjoy life).
