We've been eating cleaner. Here's our base recipe for smoothies.
1.5 cup of milk (or your favorite milk substitute)
1 cup of natural yogurt
2 cups of fruit, your choice
2 scoops of protein powder (optional)
Throw everything in the blender. Blend till as smooth as you like. It can be helpful if you whiz up the powder w/ the milk and the yogurt before adding the fruit.
We've used all kinds of combinations. Blackberries and raspberries have a lot of seeds that can get caught in your teeth and gums. Bananas make things thicker, especially if you freeze the bananas. Play with it, have fun.
