Abstract
About this talk
Background: The world is facing a dual burden of malnutrition where undernutrition and overnutrition coexist, exacerbated by climate change, ultra-processed food consumption, and gut microbiome dysbiosis. In Pakistan, 40% children are stunted while adult obesity has crossed 30%. Conventional one-size-fits-all dietary guidelines have failed to address this complexity.
Objective: To develop and evaluate a novel integrative model 'NutriFuture 2030' linking personalized nutrition, gut microbiome profiling, and locally sustainable food systems for improving dietary resilience among young adults.
Methods: A mixed-method interventional study was conducted on 120 university students (18-25 years) at PMAS Arid Agriculture University, Rawalpindi. Baseline assessments included 24-hr dietary recall, Food Frequency Questionnaire, anthropometry, and gut microbiome diversity via Bristol Stool Scale and dietary inflammatory index. Intervention included 12-week personalized meal plans based on local millets, pulses, fermented foods, and seasonal vegetables integrated with nutrition education. Pre-post changes were analyzed using SPSS v26, p<0.05 considered significant.
Results: Post-intervention, significant improvements were observed in diet quality score (+34.2%, p<0.001), reduction in fast-food frequency (-48%), improvement in digestive health (72% participants reported better gut health), and modest reduction in BMI among overweight participants (-1.8 kg/m2). Awareness regarding sustainable food choices increased from 31% to 89%. The model showed high acceptability (92%) due to cultural relevance and cost-effectiveness.
Conclusion: The NutriFuture 2030 model demonstrates that integrating personalized nutrition with microbiome-aware and sustainable food systems is feasible, culturally acceptable, and effective for combating malnutrition in low-resource settings. It offers a scalable framework for dietitians, public health policymakers, and academia.
