When is Stress Ernährung actually useful?

The question of when 'stress nutrition' is actually useful cannot be directly answered from the provided context, as it lacks specific information on this topic. In general, a balanced diet can support the physiological stress response (e.g., adequate magnesium, B vitamins, vitamin C, and omega-3 fatty acids). However, the effects of individual nutrients or so-called adaptogens (e.g., ashwagandha, rhodiola) on subjective stress are usually small and not well-supported by large clinical trials. For genetic tests claiming to reveal 'stress genes' (e.g., COMT, BDNF), the evidence for personalized dietary recommendations is weak – mostly mechanistic or observational. Stress nutrition is therefore most useful as part of a holistic approach (sleep, exercise, stress management) rather than as an isolated intervention based on genetic tests. Caveat: Many direct-to-consumer tests overstate their predictive power; medical advice is recommended.
