Foods That Provide Adequate Daily Calcium (800-1200 mg)
Dairy products are the preferred sources of calcium, with 4 portions of calcium-rich dairy foods daily providing adequate calcium to meet the recommended intake of 800-1200 mg. 1
Calcium Requirements and Food Sources
The recommended daily calcium intake varies by age and gender:
- Adults 19-50 years: 1000 mg 2
- Postmenopausal women: 1200 mg 2
- Men over 70 years: 1200 mg 2
- Older adults: 950-1500 mg 1, 2
Top Calcium Food Sources
Dairy Products (Highest Bioavailability)
Fish Sources
- Sardines with bones (½ tin): 258 mg 1
Plant-Based Sources (Lower Bioavailability)
- Calcium-enriched soy milk (200 mL): 240 mg 1
- Kale (67g): 100 mg 1
- Orange (medium): 75 mg 1
- Broccoli (2 spears): 34 mg 1
Meeting Daily Requirements
Dairy-Based Approach
To achieve 800-1200 mg daily calcium intake:
- 4 servings of dairy products daily 1, 3
- Examples of a serving:
- 1 cup (240 mL) of milk = 240 mg
- 1 cup yogurt = 200 mg
- 30g hard cheese = 220 mg
Mixed Diet Approach
- 3 dairy servings + 1 serving of calcium-rich vegetables
- 2 dairy servings + 1 serving of canned fish with bones + 1 serving of calcium-rich vegetables
- Base diet (300 mg from non-dairy sources) + 3-4 dairy servings 1
Plant-Based Approach
For those avoiding dairy:
- Calcium-fortified plant milks (2 cups): 480 mg
- Calcium-set tofu (100g): 350 mg
- Leafy greens (2 cups kale): 200 mg
- Nuts/seeds (especially almonds): 75-100 mg
- Calcium-fortified foods (cereals, juices): 100-300 mg per serving
Important Considerations
Bioavailability
- Dairy calcium has higher bioavailability than plant sources 1
- Plant-based sources (cereals, pulses, nuts, seeds, green leafy vegetables) are generally less bioavailable 1
Calcium Absorption Factors
- Vitamin D is essential for optimal calcium absorption 2
- Avoid consuming calcium with foods containing oxalates or phytates which can reduce absorption
- Spread calcium intake throughout the day for better absorption
Supplementation
- Only consider supplements if dietary intake is insufficient
- A daily calcium supplement (500 mg) may be needed for older adults who consume less than one dairy portion daily 1
- Total calcium intake (diet plus supplements) should not exceed 2000 mg/day 2
Practical Daily Meal Plan (≈1000 mg calcium)
- Breakfast: 1 cup yogurt (200 mg) + calcium-fortified cereal (100 mg)
- Lunch: Sandwich with 30g cheese (220 mg) + orange (75 mg)
- Dinner: 100g calcium-set tofu (350 mg) or 1 cup milk (240 mg) + 1 cup cooked kale (100 mg)
- Snack: Handful of almonds (75 mg)
By following these recommendations and incorporating calcium-rich foods throughout the day, you can easily achieve the recommended 800-1200 mg of daily calcium intake for optimal bone health.
