The British Medical Journal published a recent U.S. study indicating that low dietary calcium intake may lead to thyroid dysfunction, thereby increasing the risk of fractures and kidney stones.
Scientists at Brigham and Women's Hospital, affiliated with Harvard Medical School, analyzed data from 58,300 women participating in the U.S. Nurses' Health Study.Results showed that participants in the highest calcium intake group had a 44% lower risk of developing primary hyperparathyroidism compared to those in the lowest intake group.
Lead researcher Dr. Julie Parker stated that middle-aged and older women can significantly reduce their risk of primary hyperparathyroidism by supplementing calcium through diet and supplements.Adults require approximately 700 milligrams of calcium daily. Calcium-rich foods include milk and dairy products, nuts, and fish such as sardines (eaten whole, bones included).
Symptoms of Calcium Deficiency
1: Leg cramps, primarily occurring in pregnant women during deep sleep at night.If a pregnant woman experiences this symptom, it indicates her body's calcium reserves are insufficient to meet both her own and her baby's developmental needs. She should take one Dicao Calcium tablet daily to replenish calcium levels.
2: Loose teeth. Calcium deficiency in pregnant women can lead to abnormal enamel development, reduced resistance to cavities, and weakened tooth structure.If a pregnant woman experiences loose teeth and laboratory tests show blood calcium levels below normal, this indicates calcium deficiency. In such cases, the woman should supplement with at least two Dicao Calcium tablets daily to meet her body's calcium needs.
3: Pregnancy-induced hypertension (PIH) is often associated with calcium deficiency. If PIH occurs, the pregnant woman should be tested to determine if calcium deficiency is a contributing factor.
Calcium deficiency in pregnant women not only affects their own health but also impacts the skeletal development of the unborn baby. If the fetus does not receive sufficient calcium, it is prone to developing congenital rickets. Therefore, understanding the symptoms of calcium deficiency in pregnant women and promptly supplementing with Dicao Calcium Tablets when symptoms appear is highly beneficial for the health of both the mother and baby.
When should calcium supplementation begin?
Ideally, calcium supplementation should start during preconception planning. At this stage, the body requires approximately 800 milligrams of calcium daily. Beyond dietary intake, an additional 200-300 milligrams of calcium supplements should be taken daily. Expectant mothers should begin supplementation no later than 20 weeks into pregnancy, as this period marks the peak phase of fetal bone formation and development.
Can calcium be supplemented independently?
Pregnant women can purchase calcium supplements or health products from reputable manufacturers at pharmacies as long as they understand proper supplementation practices. A doctor's prescription isn't always necessary, but dosage and calcium type selection are critical. Generally, calcium carbonate products on the market offer good absorption, though this depends on the size of calcium particles during manufacturing. Smaller particles are more easily absorbed.
Are there risks to excessive calcium intake?
Without sufficient vitamin D, calcium cannot be absorbed by the body. However, excessive vitamin D intake can lead to toxicity. Excessive calcium supplementation may cause hypercalcemia and even kidney stones.
What foods provide calcium?
1. Milk: Half a pound of milk contains 300mg of calcium, along with various amino acids, lactic acid, minerals, and vitamins that enhance calcium digestion and absorption. The calcium in milk is also more readily absorbed by the body, making it an essential daily calcium source. Other dairy products like yogurt, cheese, and milk tablets are also excellent calcium sources.
2. Kelp and Dried Shrimp Shells Kelp and dried shrimp shells are high-calcium seafood options. Consuming just 25 grams daily provides 300 mg of calcium. They also help lower blood lipids and prevent arteriosclerosis.Kelp can be cooked with meat or served cold as a salad, making it a versatile ingredient. Dried shrimp shells contain even higher calcium levels—25 grams provide 500 milligrams of calcium. Thus, using them in soups or as stuffing is an excellent daily calcium supplement.
3. Soy Products Soybeans are high-protein foods with significant calcium content. 500 grams of soy milk contains 120 milligrams of calcium, while 150 grams of tofu provides a substantial 500 milligrams. Other soy products are also excellent calcium sources.
