Older adults with a higher body mass index have lower vitamin D levels, which needs to be taken into account when determining an adequate dietary vitamin D intake, a new UK study suggests.

As part of the national survey on food consumption in France (1), 1,171 adults recorded their food consumption over seven days. Researchers analyzed the results of the study using a statistical method to assess individual food preferences, individual dietary patterns and restrictions imposed by food intolerances (2). They determined the percentage of people who could be provided with 30 essential nutrients by modifying their food intake.
Results
The researchers concluded from this analysis that, mathematically speaking, it is impossible for the great majority of French adults to achieve an optimal diet with adequate nutrient content without expanding the range of foods consumed. Such information could be useful to committees establishing dietary recommendations.

Until now, recommendations for adequate nutrition could only be generalized, or at best specialized for target groups like children, sportsmen and -women or the elderly. In contrast, personalized nutrition aims to define dietary recommendations and possibly appropriate products for each individual based on their genetic and physiological characteristics. These recommendations would be designed to maintain health and avert the disease risks to which that individual might be predisposed. Micronutrients are involved in specific biochemical processes at all points in the metabolic process and play an important role in regulating health and in the onset of diseases. New analytical techniques make it possible to examine and describe the influence of micronutrients in health-preserving processes. This is usually done by analyzing a combination of biomarkers so as to provide the individual with a tailored micronutrient intake recommendation.
