Calcium is an essential nutrient for maintaining strong and healthy bones. As people age, their bones naturally become weaker and more prone to fractures and osteoporosis. Consuming an adequate amount of calcium can help slow down the rate of bone loss.
Good sources of calcium include dairy products such as milk, yogurt, and cheese, as well as green leafy vegetables like kale and broccoli. Vitamin D is an important vitamin that helps the body absorb and process calcium effectively.
