Personalized Nutrition Medicine: How Genetic Polymorphisms & Microbiome Guide Dietary Interventions
One-Size-Fits-All Nutrition is Obsolete — Precision Nutrition Based on Genetics, Microbiome & Metabolism
The history of nutrition science is littered with conflicting guidelines. The resolution lies not in finding the universally optimal diet, but in recognising that optimal diet is individual. Nutrigenomics and microbiome science are now providing the tools to make that individualisation clinically actionable.
Genetic Variation in Nutrient Metabolism
- MTHFR polymorphisms: Affect folate metabolism — homozygous carriers require higher folate intake
- ACE polymorphisms: Predict salt sensitivity and hypertension risk
- FTO variants: Affect satiety hormone response and weight management strategy
Microbiome Profiling: Moving Beyond Generic Probiotics
Stool microbiome analysis can now identify dysbiosis patterns predictive of weight gain trajectory, glucose intolerance, and systemic inflammation. Personalised probiotic interventions show superior clinical outcomes versus generic multi-strain formulations.
AI-Powered Nutritional Intelligence
Machine learning applications integrating microbiome data, genetic profiles, CGM, and dietary intake logs generate personalised meal recommendations with 60% better weight loss outcomes versus standard dietary advice.
