In July, Professor Dr. Durval Ribas Filho highlighted nutrition as a central factor in maintaining brain structure and function. He noted that dietary patterns rich in fiber, fruits, vegetables, legumes, and fermented foods support the gut-brain axis, which influences mood, memory, sleep, and learning. Such diets are linked to a lower risk of cognitive decline, depression, and neurodegenerative diseases, including Alzheimer’s, Parkinson’s, stroke, epilepsy, and migraine.

Subsequent guidance focused on anti-inflammatory foods—such as olive oil, nuts, seeds, avocado, fatty fish, and spices like ginger, turmeric, and garlic—to reduce chronic inflammation. Nutrients like omega-3 fatty acids, antioxidants, and B-vitamins (specifically B12 and folate) were identified as essential for protecting neurons from oxidative stress and supporting neurotransmitter synthesis. The Mediterranean and MIND diets were cited as evidence-based patterns for cognitive protection.

By August, research expanded to examine the specific efficacy of the MIND diet and nutritional supplements. While the MIND diet, which combines elements of the Mediterranean and DASH diets, is associated in observational studies with slowing cognitive decline, a 2023 clinical study provided more nuanced results. Regarding supplementation, while choline is essential for the neurotransmitter acetylcholine, studies do not confirm that supplementation alone can prevent neurodegenerative diseases or significantly boost brain plasticity. Similarly, while substances like Bacopa monnieri have been studied for modest effects on attention, no single supplement is currently considered a definitive preventative measure against cognitive decline.

## Timeline

### 2026-08-18: Brain health research examines MIND diet and nutritional supplements

Scientific research highlights the MIND diet and supplements like choline as tools for brain health, though experts caution that they are not guaranteed preventatives against cognitive decline.

### 2026-07-22: Anti‑Inflammatory Diet Recommendations to Prevent Chronic Disease and Boost Brain Health

Anti‑inflammatory and brain‑healthy eating guidelines recommend fruits, vegetables, omega‑3‑rich fish, olive oil, nuts, spices and B‑vitamins to lower chronic disease risk, improve immunity, and support memory.

### 2026-07-21: Nutrition's role in brain health highlighted by expert

Nutrition supports brain cells and can reduce risks of dementia, depression and neuro‑degenerative diseases; a fiber‑rich, Mediterranean‑style diet also benefits gut‑brain health, says nutrology expert.
