Recommendation sources: New Zealand Ministry of Health [ 20- 22]; World Cancer Research Fund/American Institute for Cancer Research [ 6]; U.S. Department of Agriculture and U.S. Department of Health and Human Services [ 24].
Several recommendation sources could be checked off: my own choice, family/friends, physician, midwife/nurse, pharmacist, herbal shop staff, internet, magazine/media/etc or other.

Shoppers recruited in the UK, Sweden, France, Germany, Poland and Hungary (total n = 5967) filled out a questionnaire measuring their nutrition knowledge with regard to dietary recommendations, sources of nutrients, and calorie content of food and drink products.
This instrument covers knowledge relating to current dietary recommendations, sources of different nutrients, everyday food choices and diet disease links.
This paper describes a nutrition knowledge survey carried out on a cross-section of the adult population of England (n = 1040), looking at knowledge relating to current dietary recommendations, sources of nutrients, healthy food choices and diet disease links.
The chapter finishes with a review of upcoming trends that may gain importance in future and a recommendation of sources of further information.
