BIO-319: Applied Nutrition.

BIO-319: Applied nutrition course offers a foundation of basic nutrition theory, with a focus on assessment, food components, exercise, nutrition, weight control, community programs, and resources. The application of these aspects is used to promote health and prevent illness.

Nutrition is an important branch of study since nutrients provide nourishment to the body. If people do not get the right balance of nutrients like proteins, carbohydrates, fat, vitamins, minerals, fiber, and water, the risk of developing certain diseases increases. Therefore, bio-319: applied nutrition is an essential course since it explores the different nutrients a person requires and why they need the nutrients.

What is nutrition?

Nutrition is the study of nutrients in food, how the body utilizes them, and the relationship between diet, health, and disease. Moreover, it also concentrates on how people use dietary choices to reduce the risk of diseases, how allergies work, and what happens when someone has too little or too much nutrients.

What is applied nutrition?
