It also assessed the effects of prolonged dietary restrictions on the state of micronutrients and the role of physical activity in body composition.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Bone mineral densitydietary intakegenetic disordersnutritional biomarkersnutritional riskMaterias::Investigación::32 Ciencias médicas::3206 Ciencias de la nutrición::320609 Valor nutritivoMaterias::Investigación::32 Ciencias médicas::3206 Ciencias de la nutrición::320610 Enfermedades de la nutriciónMaterias::Investigación::32 Ciencias médicas::3201 Ciencias clínicas::320110 Pediatríadoctoral thesisopen access
