Good morning Yvonne - I smiled when I read this because I just prepared my morning concoction of yogurt, dried cranberries and cashews, topped by a little cajeta (carmelized goat cheese and honey.)

So, as our stellar pediatrician explained almost 40 years ago, dairy can thicken mucus. So when you have a cold or respiratory infection and are producing a lot of mucus, avoid most dairy to help keep it thin. But the rest of the time, unless you are allergic to some part of it, it's a great way to get protein, calcium and other nutrients.

And then, "...I found out my lungs are healing well but I have a sliding hiatus hernia? Oh lovely! And what is that please?"
You can read about it here:

It is the most common type, and a common cause of GERD, your primary can help you decide when and if it may need any treatment other than your current precautions. My Dad lived with his for his entire adult life.

Glad to hear things are still improving for you. Thanks for responding to @robman so he knows there is a recovery path!
