Current micronutrient recommendations in Europe: towards understanding their differences and similarities.

Background: Nowadays most countries in Europe have established their own nutrient recommendations to assess the adequacy of dietary intakes and to plan desirable dietary intakes. As yet there is no standard approach for deriving nutrient recommendations, they may vary from country to country. This results in different national recommendations causing confusion for policy-makers, health professionals, industry, and consumers within Europe.

How we will produce the evidence-based EURRECA toolkit to support nutrition and food policy.

Background: There is considerable variation in the recommended micronutrient intakes used by countries within Europe, partly due to different methodologies and concepts used to determine requirements and different approaches used to express the recommendations. As populations become more mobile and multi-national, and more traditional foods become available internationally, harmonised recommendations based on up to date science are needed. This was recognised by the European Commission's (EC) Directorate-General (DG) Research in their 2005 call for proposals for a Network of Excellence (NoE) on 'nutrient status and requirements of specific vulnerable population groups'.

Physiological and metabolic aspects of very prolonged exercise with particular reference to hill walking.

Hill walking is a popular recreational activity in the developed world, yet it has the potential to impose severe stress simultaneously upon several regulatory systems. Information regarding the physiological strain imposed by prolonged walking outdoors in adverse climatic conditions was reported almost four decades ago and recent research has extended some of this work. These data indicate that once the walker fatigues and starts to slow or stops walking altogether, the rate of heat production falls dramatically.

Public health aspects of food fortification: a question of balance.

Micronutrient malnutrition is widespread throughout the world, with important health and economic consequences. Tools to address this situation include food fortification, supplementation and dietary diversification, each having different and complementary roles. Fortification (mandatory and voluntary) has been practised over several decades in Western countries as well as in developing countries.
