Stomach (gut) health is crucial for decision-making via the gut-brain axis, influencing mood, intuition, and even social behavior through constant communication via the vagus nerve; a healthy gut microbiome supports mental clarity, reduces anxiety, and improves intuitive choices, while poor gut health (often diet-related) can impair cognitive function, increase stress, and skew judgment, highlighting the need for a balanced diet, stress management, and mindful eating for better overall choices.
