Struggling with focus or forgetfulness? Your diet could be to blame. Ahead of World Brain Day on July 22, 2025 July 22, experts say brain-friendly foods can boost memory, focus, and mood and may even lower the risk of dementia. A neurologist shares top picks for a sharper mind.
Here are 10 healthy foods that can improve your brain functions and strengthen cognitive health:
1. Fatty fish
Fatty fish like salmon, sardines, and mackerel are rich in omega-3 fatty acids, which are key building blocks for your brain. "Omega-3s are essential for brain cell growth and development," explains Dr Sheetal Goyal, consultant neurologist at Wockhardt Hospitals. A study published in Cureus supports this, stating that the brain uses these fats to form nerve cells. Another study in Biomolecules adds that regular consumption of omega-3s may help slow down age-related cognitive decline and lower the risk of Alzheimer’s disease.
2. Blueberries
Blueberries are packed with antioxidants that help protect the brain from oxidative stress. According to research published in Advances in Nutrition, these antioxidants also improve communication between brain cells and may delay brain ageing. A handful of blueberries a few times a week can make a big difference in improving long-term cognitive health.
3. Turmeric
Turmeric is not just a spice. It is a brain booster too. "Turmeric, an Indian spice, has natural anti-inflammatory effects that can boost mood and memory," shares Dr Goyal. Its active compound, curcumin, is known to cross the blood-brain barrier and has been shown to increase serotonin and dopamine levels, feel-good chemicals that play a role in mood regulation.
4. Broccoli
Broccoli is a superfood, and for good reason. "Broccoli has high levels of antioxidants and vitamin K, both of which play a role in boosting brain health," says Dr Goyal. Vitamin K is vital for forming sphingolipids, a type of fat that is densely packed into brain cells. The antioxidants help shield the brain from damage and may support better cognitive function.
5. Pumpkin seeds
Pumpkin seeds are small but mighty when it comes to brain health. They contain magnesium, zinc, iron, and copper, all essential minerals for proper brain function. These nutrients help with nerve signaling, mood regulation, and even memory retention. A sprinkle of pumpkin seeds on your salad or yoghurt could go a long way in keeping your brain healthy.
6. Dark chocolate
When consumed in moderation, dark chocolate can actually be good for your brain. It contains flavonoids, caffeine, and antioxidants. A study in The Journal of Nutritional Biochemistry found that eating dark chocolate improved mood and increased gut microbiome diversity, suggesting a strong gut-brain connection. It suggested a prebiotic effect of dark chocolate that may help regulate mood and reduce stress.
7. Nuts
Nuts, particularly walnuts, are rich in healthy fats, antioxidants, and vitamin E, which supports brain function. These nutrients help reduce oxidative stress on the brain and may improve memory. Consuming nuts regularly has also been linked to a reduced risk of cognitive decline as we age.
8. Oranges
Just one orange a day can give you all the vitamin C you need. "Oranges offer vitamin C, which protects the brain from breakdown," says Dr Goyal. It is a type of antioxidant that helps prevent mental decline by protecting brain cells from damage caused by free radicals. A study published in Frontiers in Aging Neuroscience found that vitamin C improves focus, memory, attention, and decision speed.
9. Eggs
Eggs are a great source of choline, a nutrient that plays a vital role in memory and mental clarity. "Eggs are high in choline, which preserves memory and mental sharpness," explains Dr Goyal. They also provide B vitamins, which help regulate mood and support brain health, especially in older adults.
10. Green tea
Green tea is both a brain booster and a calming drink. "It helps keep the brain active while improving focus and reducing anxiety," says Dr Goyal. A study in Current Pharmaceutical Design highlights its caffeine content for improved alertness and its amino acid L-theanine for reducing stress and enhancing relaxation.
