For years now I've paid attention to the amount of foods and logged them on My Fitness Pal with the various free parameters set so I can track (in particular) calcium. I also have it set on Carbs, Sugar, Cholesterol, and Fiber since I have five categories I can let it calculate. This is because in 2017 I was diagnosed with Polymyalgia Rheumatica. PMR. My rheumatologist tracked that and with steroids over the next 18 months it went away, but when you're taking steroids you have to be very careful with calcium because your bones can't add more, you need to get everything you need via diet so you don't end up robbing your bones and osteoporosis, etc., can develop.

I have an electronic scale in the kitchen and especially with foods that have calcium content I weighed so I could enter it and keep track. If I didn't get enough through food then I supplemented by taking calcium tablets, broken to the point to give me the 100% requirement. Taking too much calcium causes other problems. I haven't weighed food for diet reasons much for a while, but when I'm doing the alternate day fasting I will. Most of the time I can eyeball it; 1 cup of baked squash or steamed broccoli, instead of weighing, for example.

I see this doctor once a year for follow-up (PMR often stays away, but not always; it's idiopathic so we don't know the trigger, though it's my guess that stress was a major factor.) Now she watches for osteoporosis, as does my ob/gyn. Getting the calcium right is a life-long pursuit now.

There are some foods I don't bother to log on My Fitness Pal because I know they don't have calcium content to consider, but if I'm watching calories then they do get entered. It also has a category for amount of water drunk each day, and that's a good reminder in cooler weather to stay hydrated. I haven't bothered to join the paid version of the program because the free one does what I need. It's very helpful during the alternate day fasting, but don't use the "Complete this Entry" button when you're fasting or you'll get a scold that you haven't eaten enough food to keep body and soul alive. I rarely bother to complete any of the entry days, just keep that running log.
