Foods That Sabotage Your Brain Health Exposed
Neurosurgeon Identifies Three Top Culprits to Avoid for Cognitive Wellness
Your daily dietary choices have a profound impact on more than just your physique; they critically influence brain health. Leading neurosurgeon Dr. Raveesh Sunkara highlights how everyday kitchen staples can quietly impair cognitive function over time, warning that avoiding just three common food types can significantly protect against decline.
Trans Fats: The Invisible Brain Inflamer
Foods laden with trans fats, frequently found in fried snacks and baked goods, are a major contributor to brain inflammation. Dr. Sunkara specifically points to items containing “partially hydrogenated oils,” such as chips, pastries, and fast food, as key offenders. This persistent inflammation can degrade brain function and elevate the risk of neurological disorders.
Scientific studies corroborate this concern, linking excessive trans fat intake to an increased incidence of dementia and long-term cognitive impairment. To mitigate this risk, opting for healthier cooking oils like olive or avocado oil and prioritizing whole, unprocessed foods is essential.
Sugary Drinks Trigger Cognitive Fatigue
Beverages packed with sugar are another significant dietary pitfall. These “empty calorie” drinks cause rapid spikes in blood sugar. Dr. Sunkara notes that repeated glucose surges, especially from liquid sugar, can lead to brain fatigue and potentially shrink brain volume.
Research supports this, showing a correlation between frequent consumption of high-sugar drinks and reduced volume in brain regions responsible for memory and decision-making. Such beverages are also associated with inflammation and a higher risk of neurodegenerative diseases. Experts recommend switching to water, herbal teas, or unsweetened alternatives.
A recent study published in JAMA Network Open found that individuals who consumed more added sugars had a smaller hippocampal volume, a brain region crucial for memory and learning. This suggests a direct link between high sugar intake and cognitive decline (JAMA Network Open, 2020).
Ultra-Processed Foods Disrupt Gut-Brain Axis
The third food category to shun is ultra-processed items like packaged snacks, sugary cereals, ready-made meals, and processed meats. These foods disrupt the delicate gut microbiome, which in turn compromises the gut-brain axis—the vital communication pathway between your digestive system and brain.
“The link between food and brain health is clearer than ever. By staying mindful of dietary choices and avoiding these three commonly consumed food types—trans fat-laden items, sugary beverages, and ultra-processed products—individuals can take meaningful steps toward preserving cognitive health as they age.”

This gut imbalance can foster inflammation, hinder neurotransmitter production, and contribute to mental health issues such as anxiety and depression, alongside cognitive deterioration. Prioritizing a diet rich in fresh produce, lean proteins, and whole grains is key to maintaining a healthy gut and robust brain function.
