A new eating plan that combines elements of the Mediterranean diet with a blood pressure-lowering regimen may slow down some of the brain's natural aging processes, according to recent research. Studies have shown that individuals who strictly followed this diet, known as the MIND diet, experienced less loss of grey matter in the brain over time. Grey matter is crucial for functions such as memory, learning, and decision making. It also appeared to slow down the enlargement of the brain's ventricles, fluid-filled spaces that tend to grow as brain tissue shrinks. The MIND diet has been previously linked to improved cognitive health, say researchers. The eating plan emphasizes a range of nutrient-rich foods including green leafy vegetables, other vegetables, berries, nuts, and whole grains. The diet also recommends moderate consumption of wine and includes fish, beans, olive oil, and poultry as key components, while limiting butter/margarine, cheese, red meat, pastries/sweets, and fried fast foods. The study involved a large cohort of middle-aged and older adults from the Framingham Heart Study Offspring cohort, with an average age of 60 at the start of the research. This group underwent regular health evaluations every four to eight years, beginning in 1999. In addition to these routine check-ups, participants also received MRI brain scans every two to six years, providing valuable insights into their brain changes over time. The researchers used data from at least one food frequency questionnaire completed during each participant's medical check-up between 1991 and 2001 to assess their dietary habits. The MIND diet score, which ranges from zero to 15, was calculated for each participant based on their eating habits. On average, the participants scored just under seven out of a possible 15, indicating moderate adherence to the recommended diet. Interestingly, individuals in the highest third of MIND diet adherence were more likely to be women and college-educated. These individuals also had lower rates of smoking and obesity compared to those with lower MIND scores. Furthermore, they were less likely to have conditions that can negatively impact brain health, such as type 2 diabetes, high blood pressure, and cardiovascular disease. MRI scans taken over an average follow-up period of 12 years revealed the expected age-related changes across the group, including decreases in total brain, grey matter, white matter, and hippocampal volumes. As MRI scans continued to reveal age-related changes across the group, a different picture emerged for those who adhered more closely to the MIND diet. While cerebrospinal fluid and ventricular volumes increased in most participants, individuals with higher MIND diet scores experienced slower loss of grey matter. Researchers found that each 3-point increase in MIND diet score was associated with a significant slowdown in grey matter loss, equivalent to 20% less age-related decline. This translates to the brain aging more slowly by approximately 2.5 years compared to those who followed the diet less closely. A similar trend emerged when examining ventricular enlargement. Each 3-point rise in MIND diet score was linked to slower expansion of total ventricular volume, corresponding to an 8% reduction in tissue loss and about one year of delayed brain aging. Certain foods appeared to play a more significant role in the observed associations. Higher consumption of berries, for instance, was associated with slower increases in ventricular volume, while poultry intake was linked to both slower ventricular enlargement and grey matter decline. In contrast, a diet rich in sweets led to faster ventricular enlargement and greater hippocampal atrophy, as did frequent consumption of fried fast foods. These findings suggest that MIND-recommended foods may help mitigate oxidative stress and neuronal damage, while unhealthy food choices could contribute to inflammation and vascular harm. While some foods showed expected benefits in slowing down brain aging, others did not live up to expectations. Whole grain intake, for instance, was associated with faster losses of grey matter and hippocampal volume, as well as a quicker increase in ventricular size. In an unexpected twist, greater cheese consumption was linked to slower declines in grey matter and hippocampal volume, less ventricular enlargement, and fewer white matter hyperintensities. This finding suggests that not all dairy products are created equal when it comes to brain health. The researchers observed stronger associations between a brain-healthy diet and slower brain aging among older adults. This may indicate that the MIND diet is particularly relevant for individuals at higher risk of accelerated brain aging or those experiencing greater variability in brain atrophy rates. The study's findings also suggest that combining a healthy diet with physical activity and a normal weight may help reduce the risk of neurodegenerative diseases. However, it's essential to note that this observational study cannot establish cause-and-effect relationships between dietary choices and brain health outcomes due to potential recall bias in food frequency questionnaires. The study's limitations must be considered when interpreting its findings. The researchers were unable to account for potential changes in diet over time and the impact of genetic risk factors on brain health outcomes. This may be particularly relevant given that the majority of participants were from a White ethnic background, which could limit the generalizability of the results to other populations. Further research is needed to determine whether these findings apply equally across different racial and ethnic groups. The study's conclusions reinforce the potential benefits of following a MIND diet in reducing neurodegeneration and promoting brain health in aging populations, highlighting its role as a valuable component of prevention strategies for cognitive decline. --- Source: [ScienceDaily Health](https://www.sciencedaily.com/releases/2026/09/260930225503.htm) Published by Noti Group: https://noti.group/mediterranean-diet-may-slow-brain-aging/
