Top Nuts for Calcium
Nuts offer a variety of essential nutrients, and some stand out for their exceptional calcium content. They are excellent additions to any diet, particularly for those looking for non-dairy sources of this key mineral.
Almonds
Almonds are consistently ranked as one of the best nuts for calcium. A 30-gram serving (approximately one handful) provides about 80mg of calcium. Beyond calcium, almonds are rich in protein, fiber, healthy fats, magnesium, and vitamin E, which supports skin health. The combination of these nutrients makes them excellent for bone density and overall wellness. While some studies note that the bioavailability of calcium in almonds is relatively low (below 9%), their high overall content still makes them a valuable source.
Brazil Nuts
Beyond their reputation as a top source of selenium, Brazil nuts also contribute a solid amount of calcium. A 30-gram serving can provide around 51mg of calcium. The mineral profile of Brazil nuts, which includes magnesium and phosphorus, also works synergistically with calcium to support bone health.
Hazelnuts
Hazelnuts are another nut worth noting, providing approximately 114mg of calcium per 100g. They are also known for their healthy fats and pleasant flavor, making them a great ingredient for both sweet and savory dishes. Adding a handful of hazelnuts to your daily intake can contribute meaningfully to your calcium targets.
Top Seeds for Calcium
Seeds often surpass nuts in their calcium density, making them a highly concentrated source of the mineral. A small amount can deliver a significant nutrient boost.
Poppy Seeds
Poppy seeds are perhaps the most surprising entry, packing a tremendous amount of calcium into a tiny package. A single tablespoon (9 grams) of poppy seeds contains about 127mg of calcium. In fact, 100 grams of poppy seeds contains a remarkable 1,250mg of calcium, making them one of the densest plant-based sources available. They also provide fiber, protein, and magnesium, and can be added easily to breads, salads, or sauces.
Sesame Seeds
Sesame seeds are a close contender for the top spot. A single tablespoon of unhulled sesame seeds offers about 88mg of calcium. This versatility makes sesame seeds a kitchen staple for boosting calcium. Tahini, a paste made from sesame seeds, is also an excellent option, with a tablespoon containing about 63.9mg of calcium.
Chia Seeds
These tiny seeds are famous for their omega-3 fatty acids, but they are also an excellent source of calcium. One ounce (approximately 2 tablespoons) of chia seeds provides around 179mg of calcium. Chia also contains boron, which helps the body metabolize calcium and magnesium, further supporting bone health. They can be mixed into smoothies, yogurt, or oatmeal to create a nutrient-dense meal.

How to Incorporate More Calcium-Rich Nuts and Seeds into Your Diet
Adding these nutritional powerhouses to your daily routine can be simple and delicious. Here are some ideas:
- Morning Boost: Sprinkle poppy or sesame seeds over your oatmeal or yogurt. Create a chia seed pudding by soaking chia seeds in your preferred milk overnight with a little sweetener and fruit.
- Snack Time: Snack on a handful of almonds or make a homemade trail mix with a variety of nuts and seeds. Raw or dry-roasted versions are best for controlling sodium intake.
- Savory Meals: Use tahini (sesame paste) in salad dressings or sauces. Add chopped nuts to salads or stir-fries for extra crunch and nutrients. Use a nut-based pesto for pasta or roasted vegetables.
- Baking: Incorporate almond flour into baked goods for a calcium and protein boost. Use seeds as a topping for bread, muffins, or cakes.
- Smoothies: Blend almonds or chia seeds into your morning smoothie for a creamy texture and a significant calcium kick.
Conclusion
To increase dietary calcium, turning to nature's concentrated sources is a smart strategy. Poppy seeds, chia seeds, and sesame seeds lead the charge among seeds, while almonds offer the most calcium among common nuts. By integrating these versatile and nutrient-dense foods into your meals, you can effectively support your bone health and overall wellness, even if you are avoiding dairy. Remember to consume a variety of these options to benefit from the broad spectrum of vitamins and minerals they offer, and always aim for moderation as part of a balanced diet.
