Minerals play a crucial role in maintaining overall health. For example, there are two kinds of minerals: macrominerals and trace minerals. Macrominerals include calcium, phosphorus, and magnesium, which are required in larger amounts[^1^].

Calcium is a vital nutrient for strong bones and teeth. It can be found in dairy products such as cheese and yogurt and leafy greens like broccoli, kale, and spinach[^2^].

A deficiency in calcium can lead to osteoporosis, a condition characterized by weak and brittle bones.

Phosphorus, another macromineral, is found in various foods, including red meat, eggs, and dairy products. It aids in building strong bones, teeth, and is crucial for cell and tissue growth. Furthermore, phosphorus supports proper nerve and muscle function[^3^].

Magnesium, essential for the metabolism of vitamin C, carotenoids, and other nutrients, can be found in foods like pineapple and seafood. It is also responsible for muscle and nerve function, maintaining strong bones, and regulating blood pressure. A low magnesium intake can result in high blood pressure and muscle cramps[^4^].

Trace minerals, such as sulfur and iron, are required in much smaller amounts. Sulfur supports the health of skin, hair, and nails; it can be found in various foods, including eggs and red meat[^5^].

Iron plays a vital role in the production of hemoglobin, which is responsible for carrying oxygen in red blood cells. Iron can be found in organ meats like liver, red meat, and oysters[^6^].

Dietary mineral requirements may differ due to specific factors such as age, gender, health conditions, and lifestyle choices.

Consuming a well-balanced diet consisting of various food sources, including leafy greens, seafood, dairy products, and nuts, is essential to meet these mineral needs and maintain overall health[^7^].

Several factors can influence the bioavailability of minerals in the body, including the soil they are derived from and the way food is processed or prepared. Consuming a variety of foods and rotating produce sources can help ensure that dietary mineral requirements are being met[^8^].
