Why is Calcium Important for Bones and Teeth?
Calcium is an essential nutrient that plays a critical role in maintaining strong bones and teeth. Our bodies require calcium to build and maintain healthy bone tissue, and to prevent bone loss as we age. Calcium is also important for proper nerve and muscle function, and for maintaining a healthy heart and blood pressure. However, our bodies cannot produce calcium, so we must obtain it through our diet or supplements.
According to the National Institutes of Health, the recommended daily intake of calcium for adults is 1000-1200mg per day. However, some people may require more calcium depending on their age, gender, and other factors. It's important to note that our bodies can only absorb a certain amount of calcium at a time, so it's best to spread out calcium intake throughout the day.
Calcium-Rich Food Sources
There are plenty of delicious and nutritious foods that are rich in calcium. Here are five of the best calcium-rich foods to add to your diet:
Top 10 Calcium-Rich Foods You Should Be Eating | Natural Calcium Sources

Yogurt is also a great source of calcium, with one cup of plain, low-fat yogurt containing around 400mg of calcium. In addition to calcium, dairy products also provide other important nutrients such as protein, vitamin D, and potassium.
