A diet consisting of the adequate amounts of all the necessary nutrients recommended for a healthy growth and for efficient daily activities and functions
A balanced diet contains the proper quantities and proportions of the needed nutrients to maintain good health. It must have balanced amounts in proper proportions of carbohydrates, fats, proteins, vitamins, minerals, and water intake.
In order to achieve a balanced diet, one should be able to have the following in their diet: (1) fruits, (2) vegetables, (3) grains, (4) proteins, (5) dairy, and (6) oils. Fruits and vegetables are important sources of various nutrients, especially vitamins and minerals. Dark, leafy greens such as spinach, kale, broccoli, and green beans are highly nutritious. Whole grains are preferred than refined grains since the latter lack the hull, which contains the majority of the grain's nutrition (after processing). Proteins in meats and beans are essential for growth, especially muscle and brain development. However, one should prefer lean, low-fat meats to reduce the amount of fat and cholesterol intake.1
