Quick Facts
- Sesame seeds (til) have 975mg calcium per 100g — the highest calcium content of any common Indian food, nearly 10× the calcium in milk by weight
- Ragi (finger millet) has 344mg calcium per 100g grain — making it the best calcium grain in the Indian diet and far superior to wheat or rice
- Moringa (drumstick leaves) have 440mg calcium per 100g — adding moringa to daily dal or sambar is one of the easiest ways to boost calcium significantly
- Vitamin D is required for calcium absorption — without adequate vitamin D, only 10–15% of dietary calcium is absorbed regardless of intake amount
- Phytic acid in unsoaked grains and dals blocks calcium absorption — soaking and sprouting reduces phytic acid by 30–60%, significantly improving bioavailability
- The daily calcium requirement is 1000mg for adults and 1200mg for those over 50 — most Indians consume 400–600mg daily, a significant shortfall
Why Calcium Matters Beyond Bone Health
Calcium is the most abundant mineral in the body — 99% stored in bones and teeth, 1% in blood and soft tissue. The 1% in blood is critical for:
- Muscle contraction (including the heart muscle)
- Nerve signal transmission
- Blood clotting
- Enzyme activation
When dietary calcium is insufficient, the body withdraws calcium from bones to maintain blood calcium — this silent bone loss continues for years before becoming clinically apparent as osteoporosis.
Top Indian Calcium Sources
Calcium Content of Indian Foods
| Food | Calcium (per 100g) | Bioavailability | Practical How-To |
|---|---|---|---|
| Sesame seeds (til) | 975mg | 20–25% (moderate) | Til laddoo, sesame chikki, til chutney |
| Moringa leaves | 440mg | Good | Dal tadka, sambars, moringa powder in dal |
| Ragi (finger millet) | 344mg | 15–20% (moderate) | Roti, porridge, mudde, laddoo |
| Amaranth (rajgira) | 215mg | Good | Laddoo, porridge, roti flour blend |
| A2 Paneer | 190mg | 30–35% (high) | Sabzi, paratha stuffing, raw |
| A2 Curd (per 100ml) | 150mg | 30–35% (high) | With every meal, lassi, raita |
| A2 Milk (per 100ml) | 120mg | 30–35% (high) | 2 cups daily |
| Rajma (cooked, per 100g) | 50mg | Moderate | 2× weekly in curry |
Combine sesame/ragi with dairy at the same meal for complementary calcium with good total absorbed quantity.
Calcium Absorption — What Helps and Hinders
Increase absorption:
- Vitamin D (most critical) — without it, gut calcium absorption drops to 10%
- Vitamin K2 — directs absorbed calcium into bone, not arteries
- Acidic environment — lemon juice, tamarind improve calcium release from plant foods
- Soaking and sprouting — reduces phytic acid that blocks calcium
- Vitamin C — improves mineral absorption generally
Reduce absorption (avoid near calcium-rich meals):
- Excess oxalic acid (raw spinach, beet greens) — binds calcium tightly
- Excess sodium (high salt diet) — increases urinary calcium excretion
- Caffeine (more than 4 cups tea/coffee daily)
- Very high fibre supplements taken at the same meal
Reaching 1000mg Calcium Daily Without Supplements
Sample day combining plant and dairy sources:
| Meal | Food | Calcium |
|---|---|---|
| Breakfast | Ragi porridge (100g) + A2 milk (200ml) | 344 + 240 = 584mg |
| Lunch | Toor dal + moringa tadka (30g leaves) + curd (100ml) | 132 + 150 = 282mg |
| Evening | Til laddoo (15g sesame) | ~146mg |
| Dinner | Ragi roti (1) + sabzi | ~100mg |
| Total | ~1112mg |
This sample achieves the daily requirement without supplements.

344mg calcium per 100g — the best non-dairy calcium grain. Daily ragi roti or porridge for strong bones.
Q Is plant calcium as good as dairy calcium?
Is plant calcium as good as dairy calcium?
Plant calcium is absorbed less efficiently than dairy calcium. Dairy calcium bioavailability is 30–35%; ragi is 15–20%; sesame is 20–25%. However, plant foods like sesame and moringa contain so much calcium that even at lower absorption rates, meaningful quantities are still absorbed. Practical reality: getting calcium from both plant (ragi, sesame, moringa) and dairy (curd, paneer) sources provides complementary calcium with reasonable combined bioavailability. For people who avoid all dairy, achieving 1000mg absorbed calcium from plants requires consistent effort but is achievable with ragi, sesame, and moringa as daily staples.
Q How much sesame should I eat for calcium?
How much sesame should I eat for calcium?
Two tablespoons of sesame seeds (about 20g) contain approximately 195mg calcium. At 20–25% bioavailability, that delivers about 40–50mg absorbed calcium. This is a meaningful contribution but not the entire daily requirement. Til laddoo (using 15–20g sesame) daily, combined with sesame in chutneys or rice preparations, and 1–2 cups curd, can together contribute 300–400mg absorbed calcium. Think of sesame as a calcium-boosting addition to the diet, not the sole calcium source — especially for populations with elevated needs like post-menopausal women.
