A friend asked me today whether I worry, as a vegan, about calcium. Well, I do worry about it, but not because I’m vegan. Calcium is an issue for all women. No matter what type of diet you follow, it’s important to identify good sources of this mineral.
Plant foods that are good sources of calcium include many leafy greens, like kale, collards, and mustard greens; broccoli; some legumes like black beans and vegetarian baked beans; blackstrap molasses (but not regular molasses); fortified soyfoods; fortified juices; and tofu if it is has calcium listed as an ingredient.
Some foods—like spinach, beet greens, Swiss chard, and certain seeds—have lots of calcium, but most of it doesn’t get absorbed. These foods contain compounds called oxalates that interfere with calcium absorption. Generally, calcium is well-absorbed from most other plant foods, though, and from fortified foods, too. It’s also well absorbed from supplements.
One good reason to choose vegan sources of calcium is that these foods—those that are natural sources of calcium as well as those that are fortified with it–often have advantages over milk in protecting the health of your bones.
- Calcium-fortified soymilk and calcium-set tofu contain compounds called isoflavones that may help maintain bone health.
- Calcium-fortified orange juice is rich in vitamin C, and research shows that people with high vitamin C intakes are likely to have healthier bones.
- Many leafy green vegetables–such as collards and kale–are rich in calcium and they are also high in vitamin K and potassium–two nutrients needed for strong bones.
While dairy foods provide calcium, they don’t contain vitamin C or isoflavones and they are poor sources of vitamin K and potassium.
However you choose to get calcium, make sure you get enough. The current recommendation for adults is 1000 milligrams of calcium per day. Contrary to what you may have heard elsewhere, there is no evidence that vegetarians need less calcium than meat eaters. If you don’t eat enough calcium-rich foods to meet your needs for this mineral, use supplements to make up the difference.
