was ist ein genetischer ernährungstest — which blood markers matter?

A genetic nutrition test analyzes DNA variants (SNPs) linked to metabolic pathways, nutrient utilization, and food intolerances. However, it does not directly measure current blood levels. The question of which blood markers matter is more relevant to a conventional blood panel than to a genetic test. Key blood markers for nutrition include: HbA1c (long-term blood sugar), vitamin D, vitamin B12, ferritin (iron stores), lipid profile (LDL, HDL, triglycerides), and hs-CRP (inflammation). Some genetic tests provide risk hints (e.g., MTHFR variants and folate needs), but evidence for actionable recommendations from single SNPs is often weak. Important: a genetic test does not replace a blood test. Combining genotype with current biomarkers can support personalized nutrition, but caution is warranted – many commercial tests overstate the impact of individual genes. Always consult a doctor or dietitian for abnormal results.
