Have worked out I have food intolerance to wheat products and milk. Fortunately I do seem to be able to eat cheese but try not to have too much hard cheese. I go for the softer cheeses, feta blue cheese and cream cheese.
Most of the wheat products I gave up about 3 years ago but I found it very difficult to give up milk in my tea and coffee through out the day.
I would think that it is only a small number of calories so I continued to take milk all day.
I feel so much better now I have given up milk entirely.
