In 2023, the World Health Organization (WHO) reported over 55 million people living with dementia, with Alzheimer’s disease making up about 70% of those cases. By 2050, these numbers could nearly triple, reaching 139 million. As the global population ages, the need for brain-boosting foods becomes more pressing.

Think of your brain as a high-performance sports car. It needs premium fuel to run smoothly, and that’s where your diet comes in. Foods rich in antioxidants, healthy fats, and essential nutrients are like high-octane fuel for your brain. Leafy greens, berries, fish, nuts, and whole grains are your brain’s best friends. They help keep inflammation at bay, support cognitive function, and might even lower your risk of Alzheimer’s.

Meanwhile, foods high in saturated fats, refined sugars, and processed ingredients are like putting sand in your sports car’s gas tank — over time, they cause serious damage. Instead, give your brain the quality fuel it deserves, and you might just keep it running at peak performance for years to come. Every bite counts in the battle against Alzheimer’s, and the best place to start is right on your plate.

Jasdeep Mago Jethani, neuropsychologist and psychologist explains that “Choosing the right foods can make a substantial difference in maintaining cognitive function and overall brain health.”

Plate Power

Your brain needs premium fuel to function optimally. Consider the MIND diet — a blend of the Mediterranean and DASH (Dietary Approaches to Stop Hypertension) diets — as your roadmap to brain health. This eating plan isn’t just a trend; it’s backed by research showing that it can slow cognitive decline and even lower the risk of Alzheimer’s disease. The MIND diet emphasizes brain-friendly foods like leafy greens, nuts, berries, whole grains, and fish while avoiding processed junk.
A 2021 study in The American Journal of Clinical Nutrition found that older adults who closely followed the MIND diet had a 19% reduced risk of developing Alzheimer’s disease compared to those with the lowest adherence. Another 2022 study from the Journal of Alzheimer's Disease reported that participants adhering to the MIND diet had improved cognitive function and a slower rate of cognitive decline.

The diet focuses on foods rich in antioxidants, vitamins, and healthy fats. Leafy greens, for example, are high in vitamin K, which is linked to better brain function. Berries, packed with flavonoids, have been shown to improve memory. Fish provides omega-3 fatty acids, essential for maintaining healthy brain cells. Nuts are a great source of vitamin E, which may help delay cognitive decline.

The MIND diet also emphasizes reducing intake of harmful foods like saturated fats and refined sugars. These can contribute to inflammation and oxidative stress, which accelerate cognitive decline. By avoiding these pitfalls, you give your brain the best chance to stay sharp and healthy.

“Your diet directly impacts your brain health. By focusing on nutrient-rich foods, you’re giving your brain the support it needs to function at its best," says Kavita Devgan, a mindful nutritionist.

Genes vs. Greens

The concept of epigenetics reveals that while you can’t change your genes, you can influence their behaviour through lifestyle choices, particularly diet. Epigenetics refers to changes in gene activity influenced by external factors, such as diet. Jasdeep Mago Jethani says, “Maintaining a heart-healthy diet is a proactive step toward preserving brain health.” For instance, certain nutrients and compounds in foods can activate or deactivate genes related to inflammation and oxidative stress — key factors in Alzheimer’s development. Antioxidants in fruits and vegetables can mitigate oxidative damage to brain cells, while anti-inflammatory compounds in foods like turmeric can reduce chronic inflammation. Omega-3 fatty acids found in fish support genes involved in neuronal health and synaptic plasticity, crucial for cognitive function. Conversely, diets high in processed foods and sugars can negatively impact gene expression related to inflammation and insulin resistance. “Anti-oxidants are good for your function, it limits your sugar and in general is good for you,” says Akshita Patel, Clinical Nutritionist and Educator.

Cognitive Health

Protein is crucial for brain health. As Kavita Devgan observes, "A diet rich in protein, healthy fats, and essential nutrients is essential for optimal brain function and cognitive health.” Amino acids from protein-rich foods help connect neurotransmitters, essential for cognitive sharpness. Ensuring a diet with high-quality protein is vital.
Healthy fats such as those found in fish, provide omega-3 fatty acids, which are beneficial for the brain. They help improve memory and cognitive function. Vitamin D levels are strongly associated with brain health. Low levels are linked to cognitive problems and increased risk of Alzheimer’s disease. Maintaining vitamin D levels above 50 nmol/L supports brain health. Heart Health is also tied to brain health. High cholesterol, for instance, is linked to poorer verbal memory. A heart-healthy diet is beneficial for the brain.
