Why Your Body Needs Calcium
Calcium is the most abundant mineral in the human body, and its importance goes far beyond building a strong skeleton. While 99% of your body's calcium is stored in your bones and teeth, the remaining 1% is crucial for vital functions like muscle movement,
nerve signal transmission, and maintaining a steady heartbeat. The Indian Council of Medical Research (ICMR) recommends a daily intake of 1,000 mg for most adults. However, studies show that the average calcium intake in India is often much lower, sometimes only 400-500 mg per day. This gap highlights the need to identify and incorporate various calcium-rich foods into our daily meals.
The Absorption Factor: Getting the Most from Your Food
Simply eating calcium-rich foods isn't the whole story; your body also needs to absorb it effectively. Vitamin D plays a starring role in this process, helping your body utilise the calcium you consume. Regular, safe sun exposure is a great way to boost your Vitamin D levels. However, some plant-based foods contain compounds called oxalates and phytates, which can bind to calcium and reduce its absorption. For example, while spinach is high in calcium, it's also high in oxalates, meaning your body only absorbs about 5% of its calcium content. Soaking, sprouting, and cooking can help reduce these compounds in foods like legumes and grains. The key is variety, ensuring you get calcium from diverse sources with varying absorption rates.
Embrace the Millet: The Power of Ragi
Finger millet, or ragi, is a nutritional powerhouse and one of the best non-dairy sources of calcium. Widely consumed in various parts of India, 100 grams of ragi flour contains an impressive 344 mg of calcium. This is significantly more than many other cereals. Its versatility makes it easy to add to your diet. You can enjoy it as a wholesome porridge (ragi malt), or use the flour to make rotis, dosas, and even ladoos. For those looking to increase their calcium intake without dairy, ragi is an excellent and traditional choice.
Tiny but Mighty: Seeds and Nuts
Don't underestimate the power of seeds. Sesame seeds (til) are exceptionally rich in calcium, with just one tablespoon providing nearly 90-100 mg. They are a staple in Indian sweets like til laddoos and chikki, and can also be sprinkled on salads or added to chutneys. Chia seeds are another excellent source, offering around 179 mg of calcium in two tablespoons. Among nuts, almonds are a clear winner. A handful of almonds not only provides a calcium boost but also delivers healthy fats, protein, and fibre.
Go Green: Leafy Vegetables
Many dark leafy greens are packed with calcium. While spinach's calcium is less available, others are fantastic sources. Drumstick leaves (moringa) are a standout, providing 440 mg of calcium per 100g cooked portion. Amaranth leaves (chaulai), fenugreek leaves (methi), and turnip greens are also excellent choices, commonly used in Indian cooking. Adding a serving of these greens to your dals, curries, or parathas is an easy way to significantly increase your daily calcium consumption.
Legumes, Lentils, and Soy
Legumes are a cornerstone of many Indian diets and a good source of calcium. Chickpeas (chana), kidney beans (rajma), and various dals all contribute to your daily intake. Soybeans are particularly notable, and foods made from them, like tofu (especially calcium-set tofu) and fortified soy milk, are among the best plant-based sources. A 100g serving of calcium-set tofu can contain around 350 mg of calcium. Edamame, or young soybeans, also provides a healthy dose.
Modern Fortification
Beyond traditional foods, many modern products come fortified with added calcium. These can be convenient options for those with dietary restrictions or preferences. Fortified plant-based milks, such as soy, almond, or oat milk, are widely available and can contain as much calcium as cow's milk. Some fruit juices, particularly orange juice, and breakfast cereals are also commonly fortified. When choosing these products, it's always a good idea to check the label to see exactly how much calcium has been added per serving.
