Ideal is relative to your goal. Balancing whole foods like meat, eggs, dairy, vegetables and fruits, combined with several juicing drinks would probably work just fine for most everyone.
If you are speaking in terms of a single meal, whole vegetables would give you some fiber, protein (depending on the source) would give you a complete amino acid profile, and help to slow digestion of the juice drink. This would be a better scenario in most cases for eliminating some of the issues I spoke of in my previous post.
