B-vitamins are found in whole grains, meat, dairy products, and leafy green vegetables. Good sources of vitamin C include citrus fruits, strawberries, and bell peppers.
Minerals: Building Blocks for a Healthy Body
Overview of Essential Minerals
Minerals are classified into two categories: major minerals (calcium, potassium, phosphorus, magnesium, sodium, and chloride) and trace minerals (iron, zinc, copper, manganese, iodine, selenium, and molybdenum). While major minerals are required in larger amounts, trace minerals are needed in smaller quantities.
Roles and Functions of Minerals
Minerals play essential roles in various bodily functions. Calcium, for instance, is essential for strong bones and teeth, nerve function, and muscle contraction. Potassium is crucial for maintaining proper electrolyte balance and regulating blood pressure. Iron is necessary for transporting oxygen throughout the body, while zinc supports immune function and wound healing.
Dietary Sources of Important Minerals
A well-balanced diet that includes a variety of foods can provide the necessary minerals. Dairy products, leafy green vegetables, and fortified foods are excellent sources of calcium. Potassium can be found in bananas, potatoes, and legumes. Iron is abundant in red meat, poultry, and leafy green vegetables. Whole grains, nuts, and seeds are good sources of magnesium.
Vitamins and Minerals: Synergistic Effects on Health
