Meaning of Nutrition
This field of study focuses on foods and substances in foods that help animals (and plants) to grow and stay healthy. Nutrition science also includes behaviors and social factors related to food choices. The foods we eat provide energy (calories) and nutrients such as protein, fat, carbohydrate, vitamins, minerals, and water. Eating healthy foods in the right amounts gives your body energy to perform daily activities, helps you to maintain a healthy body weight, and can lower your risk for certain diseases such as diabetes and heart disease.
