Welcome to The Principles of Human Nutrition Update. This website looks at nutrition as an exciting discipline, which draws from all branches of biology.
The intake of air, water and food is essential for every species at every stage of life. The provision of these is the responsibility of the farmer, hunter and fisherman. Their harvests are brought to the general public by caterers and food retailers.
