The evidence is moderate: rs2228570 is linked to vitamin D metabolism, but effects are small and context-dependent. rs12778366 is associated with longevity and metabolic syndrome, but most data come from association studies, not randomized controlled trials. Another example is the APOA2 CC variant: observational studies show an interaction with saturated fat, but the DIETFITS trial (JAMA 2018) found no benefit from genotype-matched diets. The American Heart Association (2025) advises against clinical use of nutrigenetic tests.

No DNA test can provide a definitive diagnosis or exact dietary prescription. For athletes or biohackers aiming to optimize carbohydrate intake, continuous glucose monitors (CGM) are more practical than DNA analysis, as genetic effects on blood glucose are small.
