What we eat every day does not just affect weight or digestion, it also plays a major role in how clearly the brain works. According to longevity expert Dr Vassily Eliopoulos, widely known as Dr Vass, the brain depends on the right kind of fuel to function smoothly. Speaking on Instagram on March 2, he highlighted that mental sharpness is not driven by willpower alone, but by nutrients coming from daily meals.

Dr Vass explained that many common problems such as mental fog, forgetfulness, low focus, or feeling drained in the afternoon may be linked to poor food choices. Signs that the diet is harming brain health include feeling foggy after meals, needing caffeine to feel alert, forgetting simple things, sudden energy crashes, and feeling irritable when hungry. These signals suggest that the brain is not getting steady and supportive nutrition.

Sharing foods that improve brain clarity, Dr Vass pointed to items rich in healthy fats, antioxidants, and key nutrients. Wild salmon supports memory and neuron repair due to its DHA content. Blueberries help reduce brain inflammation and improve recall. Avocados strengthen brain cell membranes, while eggs provide choline that supports focus and neurotransmitters. Olive oil helps slow brain ageing, and leafy greens supply folate, magnesium, and calming nutrients essential for brain balance.

On the other hand, some foods actively harm brain performance. Refined sugar can cause sudden energy spikes followed by mental crashes. Seed oils like canola and soybean increase brain inflammation, while ultra-processed snacks disturb blood sugar levels. Artificial sweeteners may weaken focus by affecting the gut-brain connection, and even small amounts of alcohol can reduce short-term memory and disturb sleep. Dr Vass also shared a simple daily meal plan focused on eggs, berries, leafy greens, nuts, fish, and roasted vegetables to support long-term brain health.
