Preeclampsia is a serious pregnancy complication that can lead to high blood pressure, kidney damage, and even death.

It affects roughly 5-8% of all pregnancies and is characterized by symptoms such as protein in the urine, severe headaches, and swelling of the hands and feet. While the exact cause of preeclampsia is still unknown, researchers have found that there is one key nutrient that may help prevent the condition: calcium.

What is Calcium?

Calcium is a mineral that is essential for strong bones and teeth, muscle function, nerve function, and blood clotting. It is also important for the development and growth of a fetus during pregnancy.

Calcium is found in a variety of foods, including dairy products, leafy greens, soy products, and some types of fish.

How Does Calcium Help Prevent Preeclampsia?

While the exact mechanism is not fully understood, studies have shown that calcium may play a role in preventing preeclampsia by improving blood vessel function and reducing inflammation.

Additionally, calcium may help regulate blood pressure by reducing the amount of aldosterone, a hormone that can raise blood pressure, in the body.

Calcium Intake Recommendations During Pregnancy

The recommended daily intake of calcium for pregnant women is 1000-1300mg per day. This can be achieved by consuming a variety of calcium-rich foods, including:.

Milk and dairy products – such as milk, cheese, and yogurt
Leafy greens – such as spinach, kale, and collard greens
Soy products – such as tofu, soy milk, and edamame
Canned fish – such as salmon, sardines, and anchovies (with bones)

In addition, some women may need to take calcium supplements to ensure they are getting enough calcium. It is best to talk to your healthcare provider about what is right for you and your pregnancy.

Other Nutrients Important for a Healthy Pregnancy

While calcium is important for preventing preeclampsia, it is not the only nutrient that is essential for a healthy pregnancy. Other nutrients that are important include:.

Folic acid – helps prevent birth defects of the brain and spine
Iron – helps prevent anemia and promotes proper fetal growth and development
Protein – important for fetal growth and development, as well as maternal tissue growth and repair
Omega-3 fatty acids – important for fetal brain and eye development
Vitamin D – important for fetal skeletal development and maternal bone health

Eating a well-balanced diet that includes a variety of nutrient-dense foods can help ensure that you and your baby are getting the nutrients you need for a healthy pregnancy.

The Bottom Line

While the exact cause of preeclampsia is still unknown, studies have shown that calcium may play a role in preventing the condition.

Pregnant women should aim to consume 1000-1300mg of calcium per day through a combination of diet and supplements, if necessary. In addition, it is important to eat a well-balanced diet that includes a variety of other important nutrients for a healthy pregnancy.
