Hi Kathleen - I continue to use dairy in my smoothies, homemade Greek yogurt with nothing added. Years ago, due to my thick, sticky mucus, we did a 2 month dairy-free test to see if it would help - no change. So I went back to limited dairy for the calcium and other nutrients. Greek yogurt, hard cheeses, and lactose free milk.
So my smoothies have a big scoop of yogurt as well as whatever I find in the fridge.

We visit our local farmers' markets for fresh local produce and it makes up at least 50% of our daily diet. We have a diverse community near both of our homes, so have added many new and unfamiliar foods at the urging of local producers.
