What is a Degree in Nutrition Science?

Nutrition science is the study of how what we eat impacts our overall health. Disease management, weight loss, and mental health are all things that come into play where nutrition is concerned, and a nutrition science program will teach you how dietary choices impact these areas of health.

Students study topics in biology, physiology, and psychology; learn about the nutritional needs of different age groups and different health conditions; and take administrative courses that provide preparation for healthcare leadership roles.

Graduates of nutrition science programs find careers in many different types of positions. Some work in gyms or health centers and teach people how to design diets that will lead to weight loss. Some work for hospitals or medical centers, teaching patients how to develop meals given new health-related dietary restrictions.

Some work for holistic health organizations, teaching people how to manage health and disease with diet. Others work for the USDA and similar organizations focused on providing public health education.

What Can You Do With a Nutrition Science Degree?

Nutrition science is a branch of science that focuses on the body’s metabolism and the effect of the diet on the physiological responses of the body. Nutrients can be classified into macronutrients and micronutrients. Macronutrients include carbohydrates, fats and proteins while micronutrients include minerals and vitamins.

Human bodies need certain quantities and balance of these nutrients to maintain a healthy normal status. These quantities are determined based on activity, health condition and body mass index. The awareness about the importance of healthy nutrition has increased significantly over the last decades which increased the demand for nutrition scientists

What does a nutrition science student learn?

Nutrition science is a field of study related to the medical and biological fields. It is actually considered a medical profession in many countries. Nutrition scientists should have knowledge about the functions of various nutrients, the physiological functions of the body and the effect of diseases on the nutrient requirements.

The following list shows the courses commonly offered in nutrient science programs:

  1. Chemistry: this is a basic science for nutrition as all foods can be viewed as chemical components and the effects of foods differ dramatically based on the chemical structure. For example, cellulose and starch are both carbohydrates that differ only in one bond making one of them edible while the other not.
  2. Biochemistry: This course introduces the chemistry of biological systems including metabolism which is particularly important for the field of nutrition. It explains the breakdown and building of nutritional components in the body.
  3. Human anatomy and physiology: these are fundamental courses that introduce the normal structure and functioning of the human body.
  4. Bacteriology: studying the bacterial cell and its activity is also important to nutrition. Some types of bacteria can cause food poisoning while other types are essential for the normal digestion of food.
  5. Dietetics: it is the scientific understanding of food components and their effect on health.
  6. Clinical nutrition: it refers to the use of dietetics for the treatment or management of diseases or health conditions such as obesity, diabetes, liver diseases or high cholesterol levels.
  7. Economics: although it may seem unrelated, having some knowledge of economics may be relevant in determining the available nutrition choices in various countries. Nutritionists should consider the differences between developed countries, developing countries and countries suffering from crises such as wars or drought.
  8. Mathematics: basic mathematical knowledge is required for the calculation and optimization of nutrient needs that may include several contributing factors.
