macromineral

Macrominerals are mineral nutrients that the body requires in relatively large amounts. These minerals are essential for numerous bodily functions, including maintaining fluid balance, supporting nerve function, building strong bones and teeth, and facilitating muscle contraction. They are also crucial for enzyme activity and the production of hormones.

The seven principal macrominerals are calcium, phosphorus, potassium, sodium, chloride, magnesium, and sulfur. Calcium and phosphorus are vital for skeletal health. Potassium and sodium are electrolytes that play a key role in regulating blood pressure and fluid balance. Magnesium is involved in over 300 enzymatic reactions in the body, while sulfur is a component of amino acids and proteins. Chloride, often consumed as sodium chloride (table salt), is important for maintaining fluid balance and producing stomach acid.

Dietary sources of macrominerals vary widely. Dairy products, leafy green vegetables, and fortified foods are good sources of calcium. Meat, poultry, fish, and dairy are rich in phosphorus. Fruits and vegetables, particularly bananas and potatoes, are excellent sources of potassium. Sodium is commonly found in processed foods and table salt. Magnesium is abundant in nuts, seeds, whole grains, and leafy greens. Sulfur is present in protein-rich foods like eggs, meat, and legumes. Adequate intake of macrominerals is generally achieved through a balanced diet. Deficiencies can lead to various health issues, emphasizing their importance for overall well-being.
