9. Rhubarb
Rhubarb is rich in fiber, vitamin K, calcium, and smaller amounts of other vitamins and minerals.
It also contains prebiotic fiber, a type of fiber that can promote the growth of healthy bacteria in your gut.
Like spinach, rhubarb is high in oxalates, so much of the calcium is not absorbed. In fact, one 2015 study found that your body can only absorb around 5% of the calcium found in rhubarb.
On the other hand, even if you’re only absorbing a small amount, rhubarb is still a source of calcium, with 105 mg of calcium per cup (122 grams) of raw rhubarb, or about 8% of the DV .
SUMMARYRhubarb is high in fiber, vitamin K, and other nutrients. It also contains calcium, although only a small amount is absorbed by the body.
10. Fortified foods
Fortified foods like cereals can make it easier to meet your daily calcium needs.
In fact, some types of cereal can deliver up to 1,000 mg (100% of the DV) per serving — and that’s before adding milk .
However, keep in mind that your body can’t absorb all that calcium at once, and it’s best to spread your intake throughout the day.
Flour and cornmeal may also be fortified with calcium. This is why some breads, tortillas, and crackers contain high amounts.
SUMMARYGrain-based foods are often fortified with calcium, including some breakfast cereals, tortillas, breads, and crackers.
