WebMD states that eating a balanced diet helps people get the correct balance of vitamins, minerals and nutrients in their body. Having the right balance of vitamins, minerals and nutrients can prevent heart disease, high blood pressure, type 2 diabetes and many types of cancer. Eating a balanced diet also can help humans feel healthier and have more energy. It boosts their immune system too.

According to WebMD, a balanced diet is a diet that incorporates fresh fruits, fresh vegetables and whole grains. Balanced, healthy diets also do not contain large amounts of food that contain fat, salt and sugar. Balanced diets that are healthy have variety. People who eat balanced diets must also eat in moderation. Eating too many calories can cause weight and disease.

According to the National Health Service a healthy, balanced diet includes eating plenty of fruits and vegetables; eating plenty of starchy foods, such as bread, rice, potatoes and pasta; eating some lean meats, such as chicken and fish; eating some milk and dairy products; and eating a small amount of foods that have high fat or sugar contents. Choosing a variety of foods from each of these groups ensures that people get the correct amount of vitamins, minerals and nutrients each day.
