MY FOODBOOK: when to see a doctor?

My Foodbook is a personalized nutrition program based on DNA and biomarker analysis. It can provide insights, but it does not replace medical diagnosis or treatment. You should see a doctor if you have specific health complaints (e.g., unexplained fatigue, digestive issues, weight changes) or if your test results indicate an elevated risk for conditions like type 2 diabetes (e.g., TCF7L2 variant rs790466). Also consult a physician if you are taking medications that may interact with genetic variants (e.g., ALDH2*2 and nitroglycerin) or if biomarker levels (e.g., cortisol) are abnormal. My Foodbook is not a diagnostic tool; it offers hypotheses that require clinical confirmation. Especially for children or pregnant women, medical advice is essential before implementing dietary changes. The evidence for many gene–diet interactions is weak (mechanistic or small studies), so recommendations should be seen as guidance, not prescription. For persistent symptoms or uncertainty, your primary care doctor or a registered dietitian with medical training is the appropriate contact.
