Setting: University of Hohenheim, Stuttgart, Germany.
Intervention: The experts met and discussed the questions and arrived at a consensus.
Conclusion: Many specific conclusions were drawn that support the general view that as we age an inadequate nutrition contributes to the loss of function and the development and progression of disease. Nutritional status is influenced by a range of medical, physiological, psychological, social and situational variables. Adequate nutrition and physical activity are aspects of a health-promoting lifestyle. The encouraging of better nutrition and the taking of exercise is a cost-effective way of decreasing the incidence and progression of age-related disease. The earlier such interventions are introduced the better.
