Key Differences
Diet specifically refers to the foods and beverages that a person chooses to consume.
Nutrition, in contrast, is the study of how those consumed foods and beverages affect the body, including metabolism, health, and disease prevention.
Diet may be temporary or long-term and can vary from person to person based on lifestyle choices, cultural background, or health needs.
Nutrition encompasses a wider array of factors such as vitamins, minerals, and other nutrients that impact overall health.
While Diet can be manipulated for short-term goals like weight loss, Nutrition focuses on long-term health and well-being.
