Patient's question:
NoDoctor's answer:
The main factors or causes of calcium deficiency in babies are a lack of vitamin D, as vitamin D promotes the absorption and utilization of calcium. When vitamin D is insufficient in a baby's body, calcium absorption decreases. This affects the growth and development of the baby's bones, leading to "rickets," which is commonly referred to as "calcium deficiency."Recommendations:
1. Dairy products are the best source of calcium for infants. In terms of calcium absorption, breast milk is the best, followed by formula milk, and then fresh milk.
2. When supplementing calcium, it is essential to also supplement vitamin D to promote calcium absorption and utilization in the intestines. The ideal calcium supplementation method is to take vitamin D and calcium separately.
3. During the summer, when outdoor activities are more frequent, babies over one year old can temporarily skip vitamin D supplementation to avoid accumulation and potential toxicity.
4. Infants have low stomach acid, so it is best to choose organic calcium sources such as calcium gluconate or calcium lactate. After the age of 2-3, when stomach acid concentration gradually increases, inorganic calcium sources with higher calcium content, such as calcium carbonate, can be chosen.
5. When sunbathing, do not do so behind glass windows, as very little ultraviolet light can penetrate them. Additionally, try to expose as much skin as possible to increase the skin's synthesis of vitamin D.
6. Green vegetables like spinach and amaranth should be blanched first to remove oxalates before stir-frying with tofu to avoid affecting calcium absorption in the vegetables or other foods.
7. Avoid adding calcium supplements to foods like milk, rice porridge, or thin congee, as phytic acid in these foods can hinder calcium absorption, reducing the body's ability to absorb calcium.
8. When cooking fish or ribs, add some vinegar and simmer slowly over low heat to fully extract the calcium from the bones and bones, as calcium is most easily absorbed when combined with protein.
9. Rice and white flour contain high levels of phytic acid, which affects calcium absorption. It is best to ferment the flour or soak the rice in warm water before cooking.
10. Soybeans (soy) have high phytic acid content, and germination can help remove it, thereby promoting calcium absorption and utilization.
11. Simmer tofu with fish, as the vitamin D in the fish promotes calcium absorption from the tofu. Stir-fry tomatoes with eggs, as the vitamin C in tomatoes enhances calcium absorption from the eggs. Eat Napa cabbage with soybeans, both of which significantly improve calcium absorption and utilization.
12. Reduce the intake of high-salt, high-fat, and high-protein foods such as hamburgers, fried chicken, potato chips, shrimp-flavored snacks, and broad bean crisps; and limit high-phosphorus foods like soda and cola. The former increases calcium excretion, while the latter hinders calcium absorption.
13. Calcium supplements are best taken between meals, as this allows the body to better utilize calcium. Taking them with meals can reduce calcium absorption efficiency.
14. Foods like egg yolks and animal liver have relatively high vitamin D content. You can feed 4–5-month-old babies some cooked egg yolks, and at 10 months, introduce pig liver porridge or goat liver porridge.
