(Well, actually, all of us together.)

That’s why we want to say a heartfelt THANK YOU for being a CITIZEN SCIENTIST spreading the word and encouraging more people to make the brain-saving changes we champion at Food for the Brain.

From Humble Beginnings to a Global Movement

Two decades ago, the idea that nutritional and lifestyle choices could alter the trajectory of cognitive health was seen as a far-fetched notion. Back then, cognitive decline was considered inevitable. The idea was drowned out by entrenched beliefs and outdated medical paradigms that focused more on reactive treatments than addressing root causes.

At Food for the Brain, we dared to challenge conventional thinking. We envisioned a future where prevention takes centre stage. Our mission became clear;: to empower you with the knowledge and tools to take charge of your brain health, shape your future, and unlock your cognitive potential.

Thus began a journey that has grown into a global movement for building cognitive resilience and brain health.

Prevention is the Only Viable Way Forward

The truth is, prevention has been sidelined in healthcare. Healthcare systems are geared toward managing symptoms, dominated by pharmaceuticals, while underlying causes remain unaddressed.

The evidence is clear: proactive steps – like improving your nutrition, staying active, managing stress, and prioritising sleep – can prevent or significantly slow cognitive decline. At Food for the Brain, you are helping to prove that prevention is real, achievable, and essential.Through our COGNITION Programme, we identify and address the modifiable risk factors for conditions like Alzheimer’s and cognitive decline. If you haven’t started your journey yet, now is the time to act.

The Power of You: Citizen Science in Action

This progress has been possible because of you—our dedicated Citizen Scientists. By the end of 2024, more than 450,000 free Cognitive Function Tests have been completed worldwide. That’s extraordinary—and it’s thanks to you!

Your commitment drives our work forward. This isn’t the result of one team, but the collective effort of thousands across 70+ countries.

Every time you take a test, complete a questionnaire, or share your experience, you’re contributing to something bigger than yourself. You are part of a groundbreaking, people-powered movement that is changing how brain health is understood, measured, and protected. The data you provide doesn’t just sit in a database—it fuels new research, shapes prevention strategies, and strengthens our ability to fight cognitive decline globally. Because of you, we are shifting the narrative from hopelessness to empowerment. Together, we are proving that your brain health—and the health of millions—is not left to chance. You’re not just participating; you’re leading the way.

And today, we’re ready to go even further.

A New Frontier: The COGNITION Biobank

We are thrilled to announce the creation of the COGNITION Biobank—a pioneering resource advancing cognitive health research.

Why does this matter? With the global cost of dementia projected to reach $2.8 trillion by 2030, it’s clear that prevention must be prioritised​. For governments and healthcare systems to take action, they need hard facts.

Thanks to nearly half a million participants like you, the COGNITION Biobank integrates data from Cognitive Function Tests, health and lifestyle questionnaires, and biomarker results. This allows researchers to explore the links between nutrition, exercise, sleep, mental stimulation, and cognitive health.

Imagine researchers discovering that something as simple as adding omega-3s, improving sleep, or managing stress could cut dementia risk in half. Now picture thousands of people across the globe applying that knowledge to transform their futures. This is the power of the COGNITION Biobank. It’s not just data—it’s hope, answers, and a global step forward. Your contributions today are fuelling discoveries that could rewrite the future for your children, grandchildren, and people around the world. You’re not only helping yourself; you’re helping millions.

The Biobank is already one of the most comprehensive anonymised databases of its kind. This is where prevention meets action. Your participation drives real, global change.Your data is safe. At Food for the Brain, we take rigorous measures to ensure all contributions remain fully anonymised, adhering to GDPR and HIPAA standards.
