The food that reduces the risk of cognitive decline by 30%.

A recent study has shed light on the importance of fish consumption in the diet, suggesting that regular intake could reduce the risk of cognitive decline by an impressive 30%. This finding comes from an international team of researchers who, after reviewing 35 individual studies involving approximately 850,000 people from various parts of the world, concluded that those who consume more fish are less likely to experience cognitive decline, dementia, and Alzheimer’s disease. This discovery highlights the relevance of the type of food we consume for our mental and cognitive well-being.

Professor Giuseppe Grosso, co-author of the study and an academic at the University of Catania, Italy, explained that the mechanisms behind this reduced risk are not yet fully understood. It is suggested that omega-3 fatty acids, which are abundant in fatty fish such as salmon, mackerel, and sardines, may play a crucial role in brain health. Additionally, Grosso mentions the possible influence of bioactive oligopeptides, beneficial compounds found in fish that could contribute to cognitive well-being.

Despite this valuable information about the benefits of fish, the study also warns of a potential crisis in the global supply of this food. Recent research published in the journal Science indicates that fish stocks worldwide are much lower than previously estimated. Graham Edgar, a marine biologist at the University of Tasmania and the lead author of the study, explained that many species are overexploited and that the supposed recoveries in fish populations could be illusory, a phenomenon they call "phantom recoveries."

The review of 230 fish stocks in various regions of the world, which included data from species in Australia, the United States, Europe, and South Africa, reveals that many stocks are trapped in a state of overexploitation, raising concerns about the sustainability of these populations and, consequently, about access to a key food for brain health.

In light of this situation, Alzheimer’s Research UK has decided to take action by partnering with John West, a well-known seafood brand in the UK, to launch the Think Brain Health campaign. This initiative aims to educate the public about the importance of brain health and how cognitive decline can be prevented. The company will donate approximately $100,000 to support this campaign, which will be reflected in 13 million packages sold in stores across the UK.

The focus of the campaign is based on the premise that up to 40% of dementia cases could be related to preventable factors. However, a recent survey revealed that only three in ten Britons are aware that they can reduce their risk of developing dementia, highlighting the need to raise awareness about this public health issue.

The Think Brain Health initiative is based on three pillars: 'Stay Sharp,' 'Stay Connected,' and 'Love Your Heart.' The latter pillar emphasizes the relationship between a healthy diet and the health of both the heart and the brain. Encouraging people to adopt a balanced diet can be crucial in the fight against cognitive decline.

Among dietary recommendations, the Mediterranean diet stands out as one of the most beneficial. It is suggested to include a variety of fish, fruits, vegetables, nuts, seeds, and olive oil, all elements that have been associated with better maintenance of cognitive skills and a possible reduction in the risk of dementia. The World Health Organization (WHO) has already endorsed the idea that a healthy diet can significantly contribute to reducing the risk of cognitive decline.

However, despite the promising results, Alzheimer’s Research UK emphasizes the need for further research to fully understand how omega-3s, found in fatty fish, influence brain health. Although the indications are positive, there is still a long way to go before definitive conclusions can be drawn about how these nutrients can protect cognitive health and reduce the risk of dementia.

This context invites us to reflect on our food choices and their impact on long-term health. In a world where information about nutrition is readily available, it is crucial that we make informed decisions that benefit not only our bodies but also our minds. Diet is a fundamental pillar of our well-being, and as these studies have shown, a diet rich in fish could be key to keeping our brains in top shape.
