Micronutrients are crucial in a balanced diet as they support numerous bodily functions, including immune response, energy production, and cellular repair. Vitamins and minerals, such as vitamin C, vitamin A, and calcium, are involved in various biochemical processes essential for maintaining health. Insufficient intake of these micronutrients can lead to deficiencies, weakening the immune system and impairing physical and mental performance. Consuming a diverse range of fruits, vegetables, whole grains, and lean proteins can ensure adequate micronutrient intake, contributing to optimal overall well-being.
