A new study from Poland reports that about 50% of adolescents may consume diets that are deficient in vitamin C and vitamin E.
The observational study estimated dietary beta-carotene (provitamin A), vitamin A, vitamin C (ascorbic acid) and vitamin E (alpha-tocopherol) intakes of a group of adolescents living in Warsaw, Poland, to assess if the micronutrient intakes meet the recommended doses (1). The dietary records showed that 47% to 67% of the participants consumed foods deficient in vitamin C and E.
The researchers commented that it is necessary to increase the consumption of vegetables and fruit which provide a valuable dietary source of antioxidant vitamins that play a significant role in protecting the body from an excess of free radicals. Another study, calculating dietary micronutrient intakes of children aged one to three years at nursery schools in Lodz, Poland, found that the meals were significantly deficient in vitamin D and iodine, and insufficient in vitamin E and iron (2).

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.
