What’s the issue?
Is it that your missing out on the goodies, or that your concerned about lacking the necessary nutrients.
I am severely allergic to milk (anaphylaxis), I have never eatin a dairy meal. I don’t feel deprived.
I do carry an epipen with me all the time. (my rav told me to carry it on shabbos even if there is no Eruv).
There are other foods that are rich in calcium.
