Your favorite snacks might be impacting your brain more than you realize. Raveesh sunkara, a well-known neurosurgeon based in Hayarabad, India, has cautioned his followers about three common nutrients that can be detrimental too brain health.
With over 1,000 brain surgeries to his name, Dr. Sunkara emphasizes that nutrition plays a crucial role in preventing cognitive decline. This decline can manifest as memory loss,clouded thinking,and reduced problem-solving abilities.
Dr. Sunkara, who shares health tips and neurosurgery videos with over 50,000 followers on Instagram under the handle @dr_raveesh, has garnered millions of views on some of his content. His video highlighting foods to avoid especially captured public attention and sparked considerable surprise.

According to Dr. Sunkara, the most harmful culprits are fries and packaged items high in trans fats. He explains that these products can lead to brain inflammation, possibly causing serious health issues over time.
Dr. Sunkara’s findings align with a 2014 scientific review titled ‘The Relationship Between Saturated and Trans Fats and Sanama,’ which suggests that such foods may elevate the risk of dementia.
Beware of Drinks High in Sugar
Next on the list are beverages loaded with sugar. Dr. Sunkara elaborates on these drinks:
“Excessive sugar in liquid form causes rapid spikes in blood sugar. These sudden fluctuations can lead to brain fatigue over time and may even contribute to brain shrinkage in the long run.”
Research on sugary drinks has indicated that reducing consumption could offer protection against cognitive disorders.
Processed Foods: A Brain Detriment
Dr. Sunkara’s third warning concerns ultra-processed foods. The renowned doctor notes that these foods can create issues within the gut, which in turn disrupts the vital gut-brain axis. After all, the brain relies on signals it receives!
Ultra-processed foods are distinct from homemade processed meals. These industrially produced items frequently enough contain additives like artificial colors, flavors, and preservatives.

Nutrient-Driven Brain Shrinkage: Surgeon’s Findings Reveal Key Culprits
As a neurosurgeon, I’ve witnessed firsthand the devastating effects of brain shrinkage – a process linked to cognitive decline, memory loss, and increased risk of neurodegenerative diseases. While genetics and age play a role, increasingly, my observations point to a critically important, frequently enough overlooked factor: nutritional deficiencies and imbalances. This isn’t simply about “eating your vegetables”; it’s about understanding how specific nutrients impact brain structure and function. This article delves into the key culprits driving nutrient-driven brain shrinkage and what you can do to protect your cognitive health. We’ll explore the science behind brain health, focusing on actionable steps you can take today.
The Brain’s Nutritional Needs: A Delicate Balance
The brain, despite comprising only about 2% of body weight, consumes approximately 20% of the body’s energy. This high metabolic demand necessitates a constant supply of essential nutrients. Brain health, as highlighted by the WHO’s recent position paper on optimizing brain health across the life course, is a complex interplay of factors, with nutrition being a cornerstone. Here’s a breakdown of critical nutrients and their roles:
Omega-3 Fatty Acids: Crucial for neuronal membrane integrity and reducing inflammation. DHA, in particular, is a major structural component of the brain.
B Vitamins: Essential for energy production within brain cells and neurotransmitter synthesis. Deficiencies in B12, folate, and B6 are especially concerning.
Vitamin D: Plays a neuroprotective role and is linked to cognitive function. Many individuals are deficient, especially in northern latitudes.
Antioxidants (Vitamin C, Vitamin E, Polyphenols): Protect brain cells from oxidative stress, a major contributor to age-related cognitive decline.
Choline: A precursor to acetylcholine, a neurotransmitter vital for memory and learning.
Magnesium: Involved in over 300 enzymatic reactions in the body,including those crucial for brain function and nerve transmission.
Culprit #1: the Western Diet & Inflammation
The standard Western diet – high in processed foods, refined sugars, and unhealthy fats – is a primary driver of chronic inflammation. This inflammation directly impacts brain health, contributing to neuronal damage and accelerated brain shrinkage.
Sugar’s Impact: Excessive sugar intake leads to insulin resistance, which can impair glucose metabolism in the brain, hindering its ability to function optimally.
Trans Fats & Saturated Fats: These fats promote inflammation and can disrupt the blood-brain barrier, allowing harmful substances to enter the brain.
Processed Foods: Often lacking in essential nutrients and loaded with additives,processed foods contribute to systemic inflammation and nutrient deficiencies.
Real-World Example: I’ve seen patients with long-term diets high in processed foods exhibit significantly smaller hippocampal volumes (the brain region crucial for memory) on MRI scans compared to those with nutrient-rich diets.
Culprit #2: Chronic Dehydration & Cerebral Blood Flow
Frequently enough underestimated, chronic dehydration can significantly impact brain health. The brain is approximately 73% water. Even mild dehydration can reduce cerebral blood flow, leading to impaired cognitive function and, over time, contribute to brain shrinkage.
Reduced Blood Volume: Dehydration decreases blood volume, reducing the amount of oxygen and nutrients delivered to the brain.
Impaired Neurotransmitter Function: Water is essential for neurotransmitter production and function.
Increased Cortisol Levels: Dehydration can elevate cortisol,the stress hormone,which can be detrimental to brain health.
Practical Tip: Aim to drink at least 8 glasses of water per day, and increase your intake during physical activity or in hot weather.
Culprit #3: Gut Microbiome Imbalance & the Gut-Brain Connection
The gut microbiome – the trillions of bacteria residing in your digestive system – has a profound impact on brain health through the gut-brain axis. An imbalance in gut bacteria (dysbiosis) can lead to inflammation, impaired nutrient absorption, and altered neurotransmitter production.
Inflammation & Leaky Gut: Dysbiosis can trigger inflammation and increase intestinal permeability (“leaky gut”), allowing toxins to enter the bloodstream and reach the brain.
Neurotransmitter Production: The gut microbiome produces neurotransmitters like serotonin and dopamine,which play crucial roles in mood and cognition.
Nutrient Absorption: A healthy gut microbiome is essential for absorbing vital nutrients like B vitamins and magnesium.
Benefits of a Healthy Gut: Improved mood, enhanced cognitive function, reduced inflammation, and better nutrient absorption.
Culprit #4: Specific nutrient Deficiencies – A Closer Look
Beyond general dietary patterns, specific nutrient deficiencies can directly contribute to brain shrinkage.
Vitamin B12 Deficiency: Common in older adults and vegans/vegetarians,B12 deficiency can lead to neurological damage and cognitive decline.
Folate Deficiency: Essential for DNA synthesis and neuronal development. Deficiency is linked to depression and cognitive impairment.
Magnesium Deficiency: Widespread due to
