Vitamins and minerals play a crucial role in overall health by supporting various bodily functions. They are essential for processes such as energy production, immune support, and bone health. Vitamins like A, C, and D, along with minerals such as calcium and magnesium, contribute to optimal physiological functioning. Deficiencies in these nutrients can lead to health issues, including weakened immunity and poor bone density. Consequently, a balanced diet that includes a variety of foods helps ensure adequate intake, promoting long-term health and well-being.
