Nutrition Data
There are a large number of web sites dealing with nutrition/food, both in terms of human nutritional requirements, the nutritional composition of foods, food supply chains, food waste and food safety. Most of these sites contain data in one form or another, but very few provide downloadable databases. In nearly all cases data is in the form of .pdf files, or in the case of nutritional composition of food, detailed data on individual food items selectable from a database. In the case of nutritional composition this is not unexpected, there are thousands of food items, raw and processed for which data is available and no file can contain them all. The links to data will be created under the following headings:
