Calcium Conundrums
Due to some health issues, we don’t eat dairy, and we try not to eat much in the way of processed, supplemented foods. However, the need for calcium doesn’t go away just because we don’t eat dairy, particularly in my growing kids.
Goal to feel at ease: 1000-1300 mg of calcium each day per person via food. (Find recommended intakes by clicking here.)
Reality: Kids not there yet. Adults in the house are off the hook.
Here is the list I made for my family to post on my refrigerator of foods and their calcium content. None of this 3 ounces or 6 ounces business, either. Content is listed in easily measurable and common forms.
Real Food Calcium Sources
I found that different sources may list HUGELY different calcium contents for the same food and food amount–so listings should be considered only as approximations. Depending on soil conditions and other environmental factors, each sample may have varying mineral/vitamin amounts, and thus the variation you’ll find on the internet.
I surveyed a few tables and sources, and I shot for a middle ground. Sometimes two values will be listed because values were REALLY different!
There are other foods besides these with good calcium content, we just haven’t incorporated them much yet (chia seeds, flax seed, herring, turnip greens, mustard greens, seaweed, and so forth). Some new moves for me from my study include encouraging figs, dates, almonds, and adding abundant dried herbs when I cook. (They can really add up, and every milligram counts to me.)

Two Days of Calcium Tracking, 998.2 mg and 877 mg
Here are two days worth of menus. Calcium content is assuming they eat it all. And because it’s a blog, I made a point to choose foods with fair calcium scores, not too high, but neither did I pick the lowest ones! Some days we have very low calcium intakes, and the days we have salmon or sardines, we have very high intakes. I figure it’s all a somewhat running balance over time, but I like to shoot for the RDA goal most days to be safest. The menus make it painfully clear to me that reaching the RDA of calcium without dairy is difficult for us. I just don’t see a way around calcium supplementation until my kids are eating larger quantity sizes and acquire a taste for certain foods high in calcium, particularly my 9-year-old. However, I will periodically re-evaluate.
Menu 1, 998.2 mg
Breakfast
2 scrambled eggs (86 mg)

My Plan
- Provide and encourage calcium-rich food sources for my family. Right now, most people in our family have reactions to dairy so I will continue excluding it in the home; however, those who don’t have reactions may imbibe at a friend’s house. Our reactions are not “severe”, just quite uncomfortable, and we will periodically try a dairy challenge and observe for reactions. We are doing this “voodoo” (said with love) diet called GAPS to see if completely changing our diet, eliminating difficult to digest foods, and introducing diverse, nutrient dense foods (such as homemade broths, natural probiotic foods, organ meats, and more) can allow the body and GI tract to metabolize and process foods better. With my seven-year old child, we have seen progress in dairy tolerance, but we’re not “there” yet.
- Track calcium intakes periodically for each family member. Try to do so over a week or even the course of a month, not just a day or two here and there. I’ve noticed that one day my calcium-weak child easily gets 1000 milligrams of calcium and another day she’ll clock-in at only 225 milligrams. I’ve found it’s easier to track one person at a time. I actually have to pay attention to whether a child eats half of their broccoli or has seconds. Or grabs a 1/4 cup or a 1/2 cup of almonds on the way to dance class.
- Provide diverse calcium sources since I can’t know the significance of oxalates, phytates, calcium-absorption up regulation and down regulation, and who knows what other factors they’ll find out there. As long as I’m providing diverse sources and the kids are actually eating them, I will try not to fret about bioavailability on a day to day basis.
- If calcium tracking indicates a family member’s input is particularly deficient, I will supplement with a calcium with vitamin D tablet once or twice daily. But I will not use this as an excuse to not deliver calcium-rich foods and encourage my kids to eat them! I will periodically reassess the need for calcium supplementation in hopes that as my children’s taste buds develop on our “new” diet, we can drop the calcium with vitamin D tablet. Doses need to be separated for maximum absorption.
- Every chance I get, I’ll push my kids out the door for some “old-fashioned” play time. Running, jumping, shooting hoop. Anything that gets them off their heinies and moving on their own two legs. Their alternative, speed clean the house.
- Sunshine. In my last post, I pointed out the controversies regarding sun. After sorting through it all, I have decided to keep doing what I’ve always done, and which seems to happen on its own naturally. Sometimes we wear sunscreen. Sometimes we wear swimshirts. Sometimes we seek shade. Sometimes we come in. Sometimes we wear hats. Whatever we do, we try to avoid burns.
