Genetic and environmental influences on nutrient intake

摘要: The relationship between genetic and the environment represents a pathway to better understand individual variations in nutrition intake food preferences. However, present literature is weakened somewhat by methodological flaws (e.g., overreliance on self-report questionnaires), discrepancies statistical approaches, inconsistent findings. Little research this topic date has included examination of micronutrient intake. purpose study improve existing environmental influences energy nutrient addressing these gaps. Twin pairs (N = 358; age 11–13 years) provided 3-day diaries, which were assessed for total energy, macronutrients, micronutrients. Structural equation modeling revealed that accounted significant portion variance (48 %), macronutrients (35–45 %), minerals (45 %), vitamins (21 %). Consistent with previous studies, shared appeared contribute little nutritional Findings vitamin mineral are novel particularly beneficial further contribution micronutrients physical health status. Better understanding linkage genes, environment, deficiencies can clarify behavioral outcomes, potentially informing risk reduction, primary prevention, intervention strategies.
