For iron deficiency, diet matters, but evidence shows that food alone often cannot correct a manifest deficiency. Heme iron from animal sources (meat, fish, poultry) is absorbed much better than non-heme iron from plants (legumes, whole grains, spinach). Vitamin C (e.g., lemon juice with meals) enhances non-heme iron absorption, while tannins (coffee, tea), phytates (whole grains), and calcium (dairy) inhibit it. A 1–2 hour gap from these inhibitors is advisable. For confirmed iron deficiency (low ferritin, low hemoglobin), oral iron supplements (e.g., ferrous sulfate) are the most effective treatment – but only under medical supervision, as overdose can cause oxidative stress and organ damage. MyBody-X tests do not diagnose iron deficiency; they may show genetic variants (e.g., in the HFE gene) that affect hemochromatosis risk (iron overload). Without blood values, no statement on current iron status is possible. The evidence for dietary recommendations in iron deficiency comes from clinical practice and nutrition studies, not genetics alone.
