Did you try Rubicon Original, Rubicon Light, Rubicon (current) or Rubicon DeLuxe ? For my money, only Rubicon (original, full-sugar, no longer available ) and Rubicon DeLuxe (the new name for original, full-sugar, Rubicon) are good, the others having reduced sugar and (probably) synthetic sweeteners.
P.S. "Unhealthy" in what way ?
