Food is a source of energy, vitamins, minerals, protein and essential fats needed by the body to live, grow and function properly, says the NHMRC. People need a large variety of different foods to obtain sufficient amounts of nutrients for a healthy body. With good nutrition, people can reduce the risk of numerous diet-related diseases, including coronary heart disease, stroke, hypertension, obesity, osteoporosis and nutritional anemia.

Proper nutrition plays a key role in maintaining a healthy lifestyle, notes the President's Council on Fitness, Sports and Nutrition. A person's daily food choices considerably affect his overall health. When combined with physical activity, a healthy diet can help people keep a healthy weight and reduce risk of chronic diseases.

Considering the significant connection between good nutrition and healthy weight, it is thus important for people to make smart food choices.
