Balanced Diet Linked to Enhanced Brain Health and Cognitive Function, Study Finds

Balanced Diet Linked to Improve Brain Health and Cognitive FunctionA recent study published in Nature Mental Health has revealed that eating a balanced, healthy diet isn’t just good for our bodies—it’s great for our brains too. Researchers from the University of Warwick looked into how the foods we choose affect not only our physical health but also our mental well-being.

They studied a large group of people, nearly 182,000, from the UK Biobank. These participants went through various tests and evaluations, including thinking skills tests, blood tests, brain scans, and even genetic tests. This helped the researchers understand how different foods impact our overall health.


To gather information about what people ate, the researchers asked them questions online. They grouped their food preferences into categories, like fruits, meats, and alcohol. Then, they used a special kind of computer program, called machine learning, to analyze all the data they collected.

The results showed that people who ate a balanced diet tended to have better mental health and sharper thinking skills. Their brains also had more of something called gray matter, which is linked to intelligence. On the other hand, those who ate a less varied diet didn’t score as well on these measures.

The study suggests that making small changes to our diets over time can lead to big improvements in our health. For example, gradually cutting back on sugary and fatty foods might help us naturally start craving healthier options.
The researchers also think that our genes play a role in how our diet affects our brain health. This means that our genes and lifestyle choices influence our brains’ health.

Lead researcher Professor Jianfeng Feng from the University of Warwick stressed the importance of starting to eat healthily early in life. He emphasized the significance of beginning to consume a balanced diet at a young age to promote healthy growth. He suggested that families and schools could contribute by providing a variety of nutritious foods and establishing an environment conducive to both physical and mental well-being.

The study also highlights the importance of government policies in making healthy food accessible and affordable for everyone.


Professor Feng emphasized the necessity of ensuring that everyone, regardless of their financial situation, has access to affordable, healthy food. He believed that this would contribute to enhancing the overall health of society.

Co-author Wei Cheng from Fudan University mentioned that their study revealed the impact of dietary choices on brain health. He stressed the importance of raising awareness about nutrition and promoting healthier eating habits, regardless of individuals’ location or financial status.

Dr. Richard Pemberton, a doctor at Hexagon Health who was not involved in the study, commented that the study confirmed the detrimental effects of poor eating habits on both bodies and brains. He urged immediate action to ensure the healthy upbringing of children and safeguard the health of future generations. He suggested using the research findings as motivation to make healthier lifestyle choices.
