Nutritional value refers to the content of essential nutrients in food, including vitamins, minerals, proteins, carbohydrates, and fats. These nutrients are crucial for maintaining health, supporting growth, and providing energy. Foods with high nutritional value, such as fruits, vegetables, whole grains, and lean proteins, contribute positively to overall well-being. Understanding the nutritional value of foods helps individuals make informed dietary choices. For example, calcium in dairy products supports bone health, while fiber in whole grains aids digestion. By focusing on foods with high nutritional value, people can improve their health and reduce the risk of chronic diseases.
