Calcium is a vital mineral that plays a crucial role in various bodily functions, particularly in maintaining strong bones and teeth. This essential nutrient is well known for its bone-supporting benefits, but it also contributes to muscle function, nerve signaling, and hormonal secretion. Unfortunately, many individuals do not consume sufficient calcium through their diet, leading to potential health issues like osteoporosis and bone fractures. This article explores how you can effectively increase your calcium intake through healthy food choices.
Understanding the Importance of Calcium
Before diving into the dietary sources of calcium, it is essential to understand why calcium is important for your body:
1. Bone Health
The most recognized function of calcium is its contribution to bone structure. About 99% of the body’s calcium is found in bones and teeth, providing them with strength and structure.
