Poor nutrition can severely impact mental health, leading to issues such as depression and anxiety. Essential nutrients are connected to the production of neurotransmitters, such as serotonin and dopamine, which help regulate mood. A diet low in vitamins and minerals may lead to deficiencies that can exacerbate mental health problems. For instance, insufficient omega-3 fatty acids can contribute to cognitive decline, while a high-sugar diet is associated with mood fluctuations. By improving overall dietary habits, individuals can positively influence their mental well-being and emotional resilience.
