wie viel fleisch pro person — can a DNA test help?

The question of how much meat per person is optimal cannot be answered by a DNA test alone. Current dietary guidelines (e.g., DGE: 300–600 g meat/week) are based on population-level evidence, not individual genetics. Some gene variants (e.g., HFE for iron overload, ACOX2 for fatty acid metabolism, CYP1A2 for caffeine clearance) may offer clues about how your body processes meat components like iron, saturated fats, or TMAO precursors. However, the evidence is mostly mechanistic or from small studies; no validated genetic test provides a personalized meat intake recommendation. Effect sizes are small and findings often inconsistent. A DNA test can be a curiosity tool but should not replace medical advice. Importantly, high consumption of red and processed meat is linked to colorectal cancer and cardiovascular disease. A test alone cannot determine the 'right' amount for you.
