Think Thursday: How Your Diet Impacts Your Brain Health
Molly Watts discusses the importance of brain health and diet on her podcast "Think Thursday." She emphasizes that the brain, despite being only 2% of body weight, uses 20% of the body's energy. Watts highlights the negative impact of a Western diet high in refined sugars, unhealthy fats, and processed foods on cognitive function and emotional regulation. She recommends a Mediterranean diet rich in omega-3 fatty acids, B vitamins, and antioxidants for better brain health, citing studies showing significant reductions in cognitive decline and Alzheimer's risk. Watts also addresses the role of supplements, advising consultation with healthcare providers and emphasizing whole foods for optimal benefits. She concludes by encouraging small, sustainable dietary changes to support brain health and reduce alcohol's impact.
Action Items
- [ ] Try making one small change to your diet by replacing a processed or high-sugar snack with a healthier option like fruit, nuts, or antioxidant-rich foods.
