This mineral is particularly important for individuals with insulin resistance or type 2 diabetes. Chromium deficiency can lead to impaired glucose tolerance and increased risk of metabolic syndrome. Natural sources of chromium include whole grains, nuts, broccoli, and meats. Including these foods in the diet can help maintain healthy blood sugar levels and support metabolic health (Jinnah, 2023).

Copper

Copper is a trace mineral that is involved in iron metabolism, the formation of connective tissue, and the functioning of the immune system. It plays a role in the production of collagen, a protein that provides structure to skin, blood vessels, and bones. Copper also acts as an antioxidant, protecting cells from oxidative damage. A deficiency in copper can lead to anemia, weakened immune function, and connective tissue disorders. Natural sources of copper include shellfish, nuts, seeds, whole grains, and dark chocolate. Ensuring adequate copper intake is important for maintaining overall health and supporting various physiological functions (Jinnah, 2023).

Iron

Iron is a critical mineral that is primarily known for its role in oxygen transport within the body. It is a key component of hemoglobin, the protein in red blood cells that binds to oxygen and carries it from the lungs to tissues throughout the body. Iron is also involved in energy production and immune function. A deficiency in iron can lead to iron-deficiency anemia, characterized by fatigue, weakness, and impaired cognitive function. Natural sources of iron include red meat, poultry, lentils, beans, tofu, and fortified cereals. It is important to consume vitamin C-rich foods alongside iron sources to enhance absorption, particularly for non-heme iron found in plant-based foods (“Assessment of Heavy Metals Concentration in Leaves of Amaranth (Amaranthus Hybridus L.) And Fluted Pumpkin (Telfaira Occidentalis Hook. F.) Sold In Akure Metropolis Nigeria”, 2020).

Manganese

Manganese is an essential trace mineral that plays a role in bone formation, blood sugar control, and antioxidant function. It is involved in the metabolism of carbohydrates, amino acids, and cholesterol, and it contributes to the formation of connective tissue. Manganese also acts as a cofactor for several enzymes involved in antioxidant defense, helping to protect cells from oxidative stress. A deficiency in manganese can lead to impaired growth, skeletal abnormalities, and reproductive issues. Natural sources of manganese include whole grains, nuts, leafy green vegetables, and tea. Incorporating these foods into the diet can help ensure adequate manganese levels and support overall health (Jinnah, 2023).

Magnesium

Magnesium is a vital mineral involved in over 300 biochemical reactions in the body, including energy production, muscle contraction, and nerve function. It plays a key role in regulating blood pressure and blood sugar levels, and it is essential for maintaining normal heart rhythm. Magnesium also contributes to bone health by aiding in the absorption of calcium. A deficiency in magnesium can lead to symptoms such as muscle cramps, fatigue, and increased risk of cardiovascular disease. Natural sources of magnesium include nuts, seeds, whole grains, leafy green vegetables, and legumes. Ensuring adequate magnesium intake is important for overall health and the prevention of chronic diseases (Jinnah, 2023).

Phosphorus

Phosphorus is a vital mineral that is essential for energy production, bone health, and DNA synthesis. It works closely with calcium to form and maintain bone structure, and it is a key component of ATP (adenosine triphosphate), the energy currency of cells. Phosphorus also plays a role in the formation of cell membranes and the regulation of acid-base balance in the body.

A deficiency in phosphorus is rare but can lead to bone pain, weakness, and impaired growth. Natural sources of phosphorus include meat, dairy products, nuts, seeds, and legumes. Ensuring adequate phosphorus intake is important for overall health and metabolic function (Jinnah, 2023).
