Why Calcium Is Important
Calcium is the most abundant mineral in the human body. In children it plays a crucial role in building strong bones and teeth, supporting muscle function, nerve transmission, and blood clotting. The rapid growth that occurs from infancy through adolescence means that adequate calcium intake during these years impacts bone density for life.
Daily Calcium Requirements
The amount of calcium needed varies by age:
| Age Group | Recommended Daily Intake |
|---|---|
| 06 months | 200mg |
| 712 months | 260mg |
| 13 years | 700mg |
| 48 years | 1,000mg |
| 918 years | 1,300mg |
These values are based on the Dietary Guidelines for Americans and reflect the amounts needed to meet the nutritional needs of 9798% of healthy children in each age group.
Top Food Sources of Calcium
Calcium is naturally present in many foods, and it is also added to fortified products. Below are common sources and the approximate calcium they provide per typical serving:
- Milk (1 cup) 300mg
- Cheddar cheese (1oz) 200mg
- Yogurt, plain (1 cup) 350mg
- Fortified orange juice (1 cup) 300mg
- Tofu prepared with calcium sulfate ( cup) 250mg
- Almonds ( cup) 95mg
- Broccoli, cooked ( cup) 45mg
- Spinach, cooked ( cup) 120mg (note: oxalates reduce absorption)
- Sardines with bones (3oz) 325mg
- Calciumfortified cereal (1 cup) 100200mg
Practical Tips for Parents
1. Make dairy a regular part of meals
Serve a glass of milk with breakfast or dinner, add cheese to sandwiches, and offer yogurt as a snack. For children who dislike milk, try flavored varieties with low added sugar.
2. Use fortified alternatives
If your child is lactose intolerant or follows a plantbased diet, choose fortified soy, almond, or oat milks that provide at least 300mg of calcium per cup.
3. Pair calciumrich foods with vitaminD
VitaminD enhances calcium absorption. Ensure daily sunlight exposure and consider foods such as fatty fish, egg yolks, or a vitaminD supplement if recommended by a pediatrician.
4. Offer calciumrich snacks
Snack ideas: cheese sticks, yogurt parfaits with fruit, calciumfortified granola bars, or a small serving of canned salmon with bones.
5. Be mindful of inhibitors
Highphytate foods (e.g., whole grains, beans) and oxalaterich vegetables (e.g., spinach, beet greens) can reduce calcium absorption. Serve them alongside calciumrich foods rather than as the sole source.
6. Encourage regular meal patterns
Skipping breakfast can reduce overall calcium intake. A quick bowl of fortified cereal with milk can easily meet a sizable portion of the daily goal.
Consequences of Inadequate Calcium
Not getting enough calcium during childhood can lead to:
- Reduced peak bone mass, increasing the risk of osteoporosis later in life.
- Rickets in severe cases, characterized by soft, weak bones.
- Dental problems such as weak enamel and higher cavity rates.
- Potential muscle cramping and abnormal nerve signaling.
If you suspect your childs calcium intake is low, consult a pediatrician before starting supplements. Excessive calcium can cause kidney stones and interfere with the absorption of other minerals.
