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.

What we eat of these depends on many factors including culture, religious beliefs, geography, age, gender , economics and taste.
Does it matter what we eat or drink? The answer is decidedly yes. Food consists of chemicals, nutrients.

Nutrition is the science which identifies what nutrients we should eat at every stage of life for ideal growth, fertility, activity and health.

Nutrition is the
science of food at all
phases of life.


The website describes the components of science based nutrition. As such it can be used as a basis for a good grounding in nutrition or a reference source.

Each section has a button to allow suggestions for improving that section.

The selection, processing and manner of eating food will be strongly influenced by what is available and by the history, social stability and economy of the community. What and how a person eats is significantly affected by the family background and traditions. Though increasingly travel is changing food choices. War, pestilence and famine can restrict food availability. Food may also be contaminated by pollutants from the environment.

Being able to eat optimal amounts is dependent upon agriculture and the political, educational and social organisation in which the person lives. The chemical substances should be available in optimal amounts and in an attractive form for metabolism . Nutrition identifies, measures and recommends optimal dietary intakes of the nutrient chemicals in health and disease.

All living creatures require a range of dietary chemicals for metabolism, growth and activity. These chemicals are obtained from a range of sources. The digestion, absorption and metabolism of ingested nutrients is determined in each individual by many factors which include inherited constitution, gender, age, activity, growth , fecundity and lactation. A person needs an adequate energy intake as well as essential nutrients to provide for the needs and control of a genetically determined constitution ( genome) which dictates protein and enzyme structure and hence metabolism. This brings nutrition to a central role in the story. The synthesis , maintenance , functioning and control of the protein complex and hence overall metabolism relies on ingested nutrients.
