Learn nutrition with online courses and programs
What is nutrition?
Nutrition is a science concerned with how an organism utilizes food. When applied to human consumption, nutrition seeks to find the most optimal combination and quantity of nutrients for growth, health, vitality, and long life. This involves studying the nutritional components of foods and their impact on the body.
Proper nutrition can help people live longer while lowering their risk for health issues. By taking nutrition courses, you can make a difference in the health and lives of others. Learning about nutrition can also help individuals on a personal level. People who understand the indicators of health can make effective adjustments to their diet and lifestyle.
Professionals in this field understand the dietary requirements of people of various ages, sizes, and activity levels. They also study the relationship between diet, health, and disease in order to design meal plans and nutrition programs that lead to improved health.Footnote 1
