Is banana shake good for health if I take it as dinner meal ?

No, a smoothie can be healthy,1/2 banana, 1Tablespoon honey, a small container of low sugar plain yogurt, 1/4 cup milk, vanilla if you want,1tsp cinnamon if you wish,and you can add a tablespoon of ground flax seed ,but might need a bit more milk if too thick...whirl in blender
