Nährstoffcheck: which diet helps?

A nutrient check (e.g., blood test for vitamins, minerals) can identify deficiencies, but it does not directly tell you which 'diet' is optimal. Evidence for personalized diet recommendations from such tests alone is limited. In most cases, a balanced, whole-food diet (e.g., Mediterranean) is sufficient to maintain nutrient status. If a deficiency is confirmed (e.g., vitamin D, B12), targeted supplementation may help – but that is not a diet, it's a correction. MyBody-X tests provide hints but not clinically validated diet plans. Beware of overblown claims: no test replaces medical advice or a healthy lifestyle. Evidence: human-moderate (blood markers) to marketing/unclear (genetics).
