Nutrition and Mental Health – 10 Common Myths
Myth #1: Food has nothing to do with mental health
👉 Truth: Food directly impacts brain chemistry, neurotransmitters and mood regulation. The gut plays a big role in this too.
Myth #2: Only medication can help mental health issues
👉 Truth: Medication can be vital but diet, nutrient status and lifestyle changes also play a big role.
Myth #3: Sugar boosts your mood
👉 Truth: Sugar gives a short high but the crash that follows often worsens anxiety, irritability and low mood.
Myth #4: Caffeine always helps focus
👉 Truth: Yes, it can help with focus but too much coffee or energy drinks can increase anxiety, reduce sleep quality and lead to brain fog.
Myth #5: All fats are bad for your brain
👉 Truth: Healthy fats (omega-3s, avocado, nuts, seeds, extra virgin olive oil) are essential for brain structure and reducing inflammation. Super important if you have ADHD.
Myth #6: Vitamins and minerals don’t affect mood
👉 Truth: Low B vitamins, Vitamin D, iron, zinc and magnesium are linked to depression, fatigue and poor concentration. Get your levels (blood test) checked before taking iron or Vitamin D.
Myth #7: Deficiencies are rare if you eat ‘normally’
👉 Truth: Many people still fall short – our food and soil are lacking in nutrients.
Myth #8: Processed food doesn’t affect mental health
👉 Truth: Diets high in ultra-processed foods are strongly linked to higher rates of depression and anxiety.
Myth #9: The gut and brain aren’t connected
👉 Truth: Gut bacteria make neurotransmitters like serotonin and dopamine that directly influence mood and focus.
Myth #10: Skipping meals doesn’t affect mental health
👉 Truth: Irregular eating destabilizes blood sugar, which can trigger irritability, stress, anxiety and mood swings.
