A recent study has found that maintaining a healthy weight and preventing excess fat accumulation in the abdominal area can help preserve brain function as individuals age. Researchers discovered that diet quality and fat distribution, particularly around the midsection, play a crucial role in cognitive health and may contribute to cognitive decline over time.
The study, conducted by an international research team from Leipzig University in Germany, Oxford University in the UK, and Montpellier University in France, analysed data from two groups of adults. The first group included over 500 middle-aged participants who were tracked for 30 years to assess their dietary habits and fat accumulation. The second group comprised approximately 660 individuals who underwent MRI brain scans and cognitive assessments at the age of 70.
Findings from the study revealed that adhering to a healthy diet during midlife supports brain function by preserving the hippocampus, a region essential for memory formation, and maintaining the integrity of white matter, which is vital for learning, focus, and problem-solving.
Moreover, the research indicated a clear correlation between increased abdominal fat and a decline in memory and cognitive abilities. Experts emphasised that the most effective period to adopt a healthy diet and reduce belly fat for cognitive health benefits is between the ages of 48 and 70.
