A new study reinforces the idea that diet plays a crucial role in maintaining brain health. Psychiatrist Guillaume Fond emphasized in an interview that "What we put in our plates is the fuel for our body, our brain, therefore our mental state," highlighting the strong link between nutrition and mental well-being. The research suggests that 80% of brains may be affected by poor nutrition due to modern eating habits, as the brain is closely connected to the rest of the body. The study, conducted by researchers from Zhejiang University School of Medicine and their American counterparts, explored the relationship between diet and brain aging. It focused on the MIND diet, an eating plan designed to promote brain health. The MIND diet, which stands for Mediterranean-DASH Intervention for Neurodegenerative Delay, combines elements of the Mediterranean diet and the DASH diet. It encourages the consumption of leafy green vegetables, berries, nuts, whole grains, fish, legumes, poultry, and olive oil, while advising against the intake of butter, cheese, red meat, sweets, and ultra-processed foods. Researchers analyzed data from nearly 2000 participants in the Framingham cohort, who were followed for over twelve years through food questionnaires and repeated brain MRIs. They found that individuals who closely followed the MIND diet experienced slower loss of gray matter, equivalent to about 2.5 years of less brain aging over the 12-year period. The study indicates that greater adherence to the MIND diet is associated with slower structural brain atrophy, particularly in the loss of gray matter and the increase in ventricle volume. These findings support the potential of the MIND diet as a strategy to protect brain health and delay aging-related changes in the brain. The research also points to the importance of specific foods in slowing the degradation of gray matter, which is vital for memory, learning, decision-making, and information processing. Berries and poultry were found to be especially beneficial, as they are rich in antioxidants and high-quality protein, which can reduce oxidative stress and help protect brain cells. The study suggests that making simple dietary adjustments, such as choosing poultry over red meat and reducing the intake of sweets and fried foods, could contribute to better brain health.
