Obesity: balanced diets and treatment
An essential aspect of maintaining the body is the consumption of food. The range of foods that we eat is known as our diet and the components of food that are digested, absorbed and used in bodily functions are known as nutrients. Nutrients supply the body with both energy and with the components for growth and repair. In this course we will examine the various roles of nutrients within the body and look at the effects of nutrient deficiencies or excesses, both of which can lead to adverse health effects.
