Is a vanilla protein shake with milk frozen banana and all natural peanut butter healthy for you after weight training?

Protein and sugar: After a hard work out your body needs protein and some sugar (glucose). You should try not to eat fat and /or a huge amount of sugar. Try to find a protein shake that provides this balance. Non fat milk and a banana both provide some glucose without the fat content. I worry that your frozen shake has too much sugar and fat, which would would counter the affect of your workout.
