What Can You Do With a Nutritional Science Degree?

Undeniably, nutrition is greatly significant to daily living. The decisions we make about food affect our performance during the day, our quality of sleep and our overall wellbeing. 

But how are we to know which nutrition decisions are the right ones for us? That’s where nutrition science comes in. Nutrition science provides essential information on how the nutrients in the food we consume interact with our lifestyles and health.  

If you’re interested in discovering the science behind nutrition, then a nutrition major might be the right fit for you. Read on to learn the answer to “What is Nutritional Science?" and the types of nutrition science jobs.

What is Nutritional Science?

Nutritional science provides an inside look at the effect of food on human health. Per Kara Coleman Fields writing for U.S. News and World Report, nutrition scientists “help others make healthy choices for their lives, from shaping school lunch menus to educating people on what to eat, taking into consideration individual needs, age and special circumstances such as pregnancy.” From investigating healthier options for growing food to analyzing how different nutrients impact our daily living, nutrition science takes into account a variety of factors.

A registered dietitian nutritionist uses knowledge of nutritional science to provide patients with personalized recommendations, helping them improve daily functions such as exercise and sleep. Applied nutrition strategies also help to combat diseases and disorders—and boost wellbeing overall.

In addition to working with individual human nutrition, registered dieticians use their knowledge in community nutrition programs. They develop nutrition education plans for community services and implement food safety practices.

Because it affects us all, nutrition science influences our lives in many ways. So, what do nutrition science majors study?

What Is Studied in Nutritional Science?

On top of general education courses, a nutritional science degree includes an introductory course about the relationship between nutrition and human health. Nutrition science encompasses topics from other fields, like health science and life sciences. Prospective students can expect to study topics such as: 

  • Food science
  • Dietetics
  • Anatomy and physiology
  • Chemistry
  • Practice in health care
  • Nutrition counseling
  • Food system
  • Nutrition education
  • Statistics
  • Nutrition research

Nutritional sciences majors may choose to expand their knowledge by studying health psychology, food and culture, or community nutrition, which examines nutrition problems and policies in local and global communities. 

Additionally, some nutrition science programs give students the opportunity to gain supervised experiential learning. Hands-on experience built into your bachelor’s degree helps you to become a competitive candidate and feel prepared for the next step in your career in nutrition science—whether that means pursuing a job or graduate school. 

Nutrition touches many areas of our lives, and nutrition science degrees, fittingly, cover a wide variety of topics. Nutritional sciences degree programs prepare students for the different situations they may encounter in their careers.

Why Is Nutritional Science Important?

Nutritional science has a major impact on society. “Nutrition science is important because every person needs to eat to survive and how we eat influences how we feel, function and live our lives,” according to Kim Milano, assistant professor of health sciences at North Central College. 

Being mindful of nutrition benefits quality of life—at any stage. Whether working with youth or elderly patients, nutrition scientists have the opportunity to positively impact a person’s life. Through helping someone discover food sensitivity or prevent a disease, nutritionists have the power to change lives.

Furthermore, nutrition science enacts change that affects generations. Nutrition scientists use their knowledge and skills to set up nutrition education programs in a community. They spread awareness about how human health is impacted by the food system, striking significant transformations that last. Altogether, nutrition is crucial for each of us, which means the work of nutrition scientists is highly valued.
