“Human Nutrition: Vitamins, Minerals, and Water” introduces key micronutrients and explains how vitamins, minerals, electrolytes, and water support human health. The video defines fat-soluble and water-soluble vitamins, outlines functions of vitamins A, D, E, K, B-complex, and C, and connects food sources to balanced nutrition. It also covers minerals such as calcium, phosphorus, iron, and sodium, including roles in bone growth, energy metabolism, red blood cells, nerve function, and fluid balance. Additional concepts include oxidation, antioxidants, free radicals, dehydration, electrolyte balance, dietary reference intakes, supplements, fortified foods, deficiency, and toxicity. This health and life science content aligns well with school curricula in nutrition, biology, and wellness education. Part of the "Human Nutrition" series.
