Most fruits are not significant sources of calcium compared to dairy or leafy greens, but a few stand out. Dried figs top the list at 162 mg per 100 grams, and prickly pear comes in at 118 mg per 100 grams. With most adults needing 1,000 to 1,200 mg of calcium daily, fruit alone won’t get you there, but the right choices can meaningfully contribute.
The Fruits With the Most Calcium
Here’s how the highest-calcium fruits compare, all measured per 100 grams of raw or dried fruit:
- Dried figs: 162 mg
- Prickly pear: 118 mg
- Kiwi: roughly 50 mg per cup
- Black mulberries: 39 mg
- Fresh figs: 35 mg
- Papaya: 22 mg
- Oranges: about 20 mg per cup of juice (without fortification)
Dried figs are the clear winner. A single cup of dried, uncooked figs delivers around 300 mg of calcium, which is roughly 30% of what most adults need each day. That puts them on par with a glass of milk. Fresh figs have calcium too, but drying concentrates the mineral along with everything else. The trade-off is calories: 100 grams of dried figs packs 249 calories versus 74 for fresh.
Prickly pear is an underappreciated option. At 118 mg per 100 grams, it offers more calcium than most common fruits by a wide margin. It’s widely available in Latin American and Mediterranean grocery stores, and its sweet, mild flavor works well eaten fresh or blended into smoothies.
Dried Fruit vs. Fresh Fruit
Drying fruit removes water, which concentrates nutrients per gram. This is why dried figs contain about 4.5 times more calcium than fresh figs by weight. The same principle applies to other dried fruits like apricots and dates, though none match figs for calcium density.
The catch is that dried fruit is also calorie-dense. You’ll get 162 mg of calcium from 100 grams of dried figs, but you’ll also consume 249 calories. From fresh figs, 100 grams gives you 35 mg of calcium at just 74 calories. If you’re watching calorie intake, mixing fresh and dried fruit is a reasonable middle ground. A small handful of dried figs (about 3 or 4) adds roughly 75 mg of calcium and fits easily into a snack or breakfast bowl.
Fortified Orange Juice
Fortified orange juice is technically a fruit product, not a whole fruit, but it deserves mention because the numbers are impressive. A single 8-ounce glass of calcium-fortified orange juice contains about 350 mg of calcium, roughly 30% of the daily value for most adults. That’s more than any whole fruit can offer in a typical serving.
For comparison, regular orange juice from concentrate has only about 20 mg per cup. The difference is entirely from added calcium. If you already drink orange juice, switching to a fortified version is one of the simplest ways to boost your intake. Just check the nutrition label, since calcium content varies by brand.
Why Calcium From Fruit Isn’t Always Absorbed
Not all the calcium listed on a nutrition label ends up in your bones. Your body’s ability to absorb calcium from a food depends heavily on what else is in that food, and the biggest interference comes from a compound called oxalate.
Oxalate binds to calcium in your digestive tract, forming an insoluble complex that your body can’t absorb. Rhubarb is the classic example. Often grouped with fruits in cooking, rhubarb contains calcium but also extremely high levels of oxalate, which makes it a poor practical source. Research published in the Journal of Nutrition found that oxalate is “by far the most potent inhibitor” of calcium absorption. Adding just 0.1 grams of oxalate to a food can reduce calcium absorption by about 10 percentage points.
The fruits on the list above, particularly figs, kiwi, and oranges, are relatively low in oxalate, which means the calcium they contain is reasonably available to your body. If you eat rhubarb and want to reduce its oxalate impact, cooking it with milk cuts soluble oxalate by about 70%, according to research on rhubarb bioavailability. The calcium in milk binds to the oxalate before it reaches your system, neutralizing much of the effect.
How Much Calcium You Actually Need
The recommended daily intake for calcium varies by age and sex. Adults between 19 and 50 need 1,000 mg per day. Women over 50 and all adults over 70 need 1,200 mg. Pregnant teenagers need the most at 1,300 mg, while pregnant adults aged 19 to 50 stay at 1,000 mg.
To put fruit in perspective: even a full cup of dried figs (300 mg) covers less than a third of the daily target. Fruit works best as a supplementary calcium source alongside dairy, fortified plant milks, leafy greens like kale and bok choy, or canned fish with bones. Relying on fruit alone for calcium would require eating impractical amounts.
Practical Ways to Add Calcium-Rich Fruit
The easiest approach is making dried figs a regular snack. Three or four dried figs a day adds roughly 75 mg of calcium with minimal effort. Chopping them into oatmeal, yogurt, or salads works well too, and pairing them with a calcium-rich food like yogurt means a single breakfast can deliver 300 to 400 mg.
Kiwi is another versatile option. While its calcium content is modest, it’s also high in vitamin C, which some evidence suggests supports calcium metabolism. Slicing a couple of kiwis into a morning smoothie made with fortified orange juice or calcium-set tofu creates a surprisingly calcium-dense meal from mostly plant sources.
Prickly pear can be harder to find depending on where you live, but if you have access to it, the calcium payoff is worth the slightly unusual preparation. Peel off the skin, slice, and eat fresh, or blend the flesh into agua fresca or smoothies. At 118 mg per 100 grams, two medium prickly pears rival a small glass of milk.
