1. Oysters
Oysters are nutrient-dense foods, rich in calcium, iron, selenium, and potassium, all of which are beneficial for both the mother and the baby.

For this reason, you can add some seaweed to your daily meals, such as in soups or broths. You can also include dried seaweed in rice or noodle dishes for a healthy addition to both your and your baby's diet.

3. Sesame Seeds
Until now, sesame seeds have been widely recognized as beneficial for heart health. However, not many people know that sesame seeds are also an excellent source of calcium for pregnant women.
It's simple—just sprinkle a tablespoon of roasted sesame seeds on your rice during meals, mix it well, and enjoy. You can also sprinkle them on salads for a healthy boost.

4. Yogurt
Yogurt is richer in calcium and protein compared to regular milk, which helps both the mother and baby develop stronger bones and teeth. Yogurt also contains beneficial probiotics that improve digestive and immune system health.
In addition, yogurt has some bacteria that produce antibiotics capable of eliminating harmful bacteria in the gut. Moreover, yogurt contains beneficial bacteria that prevent infections in the intimate areas.

A cup of broccoli juice contains a significant amount of calcium, manganese, potassium, phosphorus, magnesium, and iron. Additionally, it is rich in vitamins A, C, and K, which are among the most effective cancer-fighting components.
If you don't prefer broccoli juice, you can also prepare it in various other dishes like stir-fried or boiled broccoli, which are also highly nutritious for mothers.

6. Bananas
Bananas help enhance focus and mental sharpness. But their benefits go beyond that—they are rich in potassium and electrolytes, which help prevent bone degeneration and maintain optimal calcium levels in the body.
Additionally, bananas also boost the sensitivity of the nervous system, improve immunity, and promote metabolism. Eating a few bananas each day can truly help a pregnant woman regain energy quickly after a stressful and tiring day at work.

7. Bok Choy
Bok choy is a top choice for mothers to ensure they provide enough calcium for their children, supporting overall development. Bok choy is rich in several components that supplement calcium; in 100g of bok choy, there are over 100 mg of calcium, which aids in bone and brain development, increases height, and provides additional vitamins A, C, folic acid, iron, beta-carotene, and potassium.
Potassium in bok choy helps maintain healthy muscles and nerves, while beta-carotene reduces the risk of lung and colon cancer. Therefore, pregnant women should consider adding a cup of bok choy juice or a bok choy salad to their daily meals.

8. Sardines
85 grams of sardines contain 325mg of calcium. Sardines are one of the best non-dairy sources of calcium. The bones of sardines are the richest source of calcium, so it's advisable to eat the entire fish and choose brands that preserve the bones in the processing.

9. Kale
Kale not only provides additional calcium but also supplies a significant amount of vitamins A, C, folate, iron, and potassium. Pregnant women should aim to include as much kale as possible in their daily diet!

10. Spinach
Just like broccoli, spinach, also known as 'water spinach,' is another leafy green packed with calcium. This vegetable is rich in potassium, zinc, phosphorus, and selenium, which help protect the liver.
The carotenoid neoxanthin in spinach has the potential to destroy prostate cancer cells, while beta-carotene helps eliminate colon cancer cells.

11. Artichoke
This fiber-rich plant contains more manganese and potassium than any other vegetable. Its leaves are packed with compounds that can reduce the risk of stroke, while the vitamin C in it helps boost the immune system. You can cook it in a soup or enjoy it as a tea.

12. Sweet Potato
One large sweet potato contains 68mg of calcium. It is a great source of calcium, potassium, and vitamins A and C. Besides the usual boiled or steamed versions, pregnant women can also enjoy dried sweet potato with a little sugar for a tasty treat.

Kiwi is another fruit rich in calcium that helps protect the bones. Additionally, the vitamin C, lutein, and carotene found in the fruit reduce the risk of cardiovascular diseases.
Enjoy kiwi as a dessert or pair it with a salad, and it will keep you feeling refreshed throughout the day.

14. Dried Plums
Dried fruits, particularly dried plums, are an excellent, healthful snack for expectant mothers. The rich purple skin of dried plums is packed with copper and boxite, both of which help prevent the aging of bones.
They are also high in fiber, with inulin that promotes easier digestion, and helps prevent constipation during pregnancy.

15. Almonds
23 almonds provide approximately 75mg of calcium. Almonds are among the healthiest nuts due to their high protein content and rich supply of vitamin E and potassium.
Although almonds contain fats, these are healthy fats that can help lower bad cholesterol levels in the body when consumed in moderation by expectant mothers.

16. Tofu
Tofu is a great source of plant-based protein and an excellent source of calcium. It also contains iron, phosphorus, and fiber, which are beneficial for digestion. The vitamins found in tofu include many B vitamins, especially B1, B2, and B6.
Notably, tofu is rich in isoflavones, which help boost female hormones and alleviate health issues such as cardiovascular diseases, premenopausal disorders, cancer, and osteoporosis.

17. Oats
Among the various cereals, oats have the highest calcium content, being 7.5 times richer in calcium than white rice. While the calcium in oats is not as abundant as that in milk,
it still plays a role in preventing calcium deficiency during pregnancy. If you cook oatmeal with black sesame seeds, the calcium absorption will be even more effective.
Overall, there is a wide variety of calcium-rich foods available for expectant mothers. Moms can choose what suits their tastes and preferences to ensure proper nutrition during pregnancy.

18. Freshwater Shrimp
Freshwater Shrimp refers to shrimp living in freshwater bodies like ponds, lakes, and rivers. Modern research has shown that shrimp are among the richest sources of calcium. In every 100g of freshwater shrimp, there are up to 1,120 mg of calcium, and in 100g of peeled shrimp, 882 mg of calcium. Thus, freshwater shrimp is one of the most calcium-rich foods that expectant mothers should not overlook.
Scientific studies have also proven that calcium is an essential element in bone structure, contributing to strong bones. Many believe that the shrimp shell contains a lot of calcium, but in reality, the main calcium source in shrimp is primarily in the meat, legs, and claws. Therefore, even if one tries to consume the shrimp shell, the body will simply expel it. The shell is not as rich in calcium as some people mistakenly think.

19. Orange
Oranges are famous for their high Vitamin C content, but they are also among the fruits that contain the most calcium. Each 100g of orange provides 40 mg of calcium. Scientists have proven that regular consumption of orange juice can help prevent osteoporosis and other health issues during pregnancy.
To maximize the calcium intake from oranges, expectant mothers can consume the peel along with the juice or slices. This way, the orange will benefit both the mother and the baby.
Additionally, the potassium in orange juice aids in metabolism and overall health, enhancing iron absorption and contributing to strong bones and teeth in the baby.

20. Sea Crab
Sea crab is truly a nutrient powerhouse, packed with calcium and other essential nutrients that benefit both the mother and the baby.
Studies have shown that consuming sea crab weekly during pregnancy can provide the best nutritional benefits for both mother and child.
