While I am not a nutritionist, I do know that mangoes are full of vitamin C, potassium and fiber. In my opinion, dairy should be eaten in moderation so if you're making your shakes with dairy milk and yogurt, then you don't want to have them for breakfast, lunch and dinner! But "healthy" is subjective, and to me this shake is higher on the healthy scale than many others. For real nutritional advice, consult with a nutritionist.
