I remember reading somewhere, and being told by a foodie friend, that we should not eat fruit and vegetables together as they require different digestive enzymes & digestion times. I think there was some concern of the different enzymes cancelling each other out & upsetting the digestive process.

However - I LOVE spinach & strawberry salad, and can't say I had a bellyache afterward.

At any rate - I keep my morning smoothies all-fruit. DH doesn't like to eat in the morning so this makes us both happy:

2 bananas
1 cup frozen blueberries
handful of strawberries or 2 plums, or mango, or 2 peaches, or whatever looked good
2-3 tbs peanut butter
almond milk

Yum baby yum!
