There is plenty of research on how what you eat can influence your cognitive function and perhaps stave off brain decline such as dementia and Alzheimer’s disease. Wondrously, they are similar to the prostate saving strategies in The Prostate Playbook –

• Reduced added sugar, including artificial sweeteners
• Focus on ‘good’ fats: olive oil, avocado, nuts, omega-3 fatty acids from fish
• Anti-inflammatory spices: turmeric, cinnamon, thyme,
• Ensure good quality sleep – manage apnoea, adequate time and comfort
• Exercise – aerobic and resistance but it should not be stressful in its own right
• Avoid environmental toxins – pesticides, heavy metals, arsenic
• Socialise – engaging with others face-to-face if possible
