An account of the issues to be addressed in tackling the nutritional
enhancement of plants (including increasing levels of bioactive secondary
metabolites) can be found in published reviews commissioned under the EU’s
concerted action project ‘The Nutritional Enhancement of Plant Foods in
European Trade (NEODIET)’, 2000, J Sci Food & Agric. 80 (7): 793–1137.
Some of the issues raised in relation to the use of plant biotechnology in food
and feed production are discussed in papers contained in a special edition of Science (Plant Biotechnology: Food & Feed, 1999, Science 285: 367–389.)
