The researchers calculated the impact of diet and weight on a person’s “brain age,” determined by how the brain appears on MRI scans, and determined that certain lifestyle factors such as healthy diet, being overweight or obese, and liver health all influence brain aging over relatively short time periods. Weight loss, even losing just one percent of one’s total body weight, appears to reverse brain aging faster than expected. The study, published in eLife, followed 300 participants for 18 months and found that obesity is linked to brain aging at a faster rate than would normally be expected. Switching to a Green Mediterranean Diet, which calls for avoiding red or processed meat and processed foods, and places an emphasis on eating more polyphenol-rich foods such as leafy greens, colorful fruit, high-fiber vegetables and whole grains, nuts, seeds and olive oil, positively affects brain health and can lead to weight loss that helps reverse brain aging. Those included eating more polyphenol-rich foods, which benefits brain health, and losing weight, which also helps cognitive function and actually appears to reverse aging in the brain. The study, out of Ben-Gurion University in Negev, Israel, identified lifestyle factors that can influence brain age in as little as 18 months. The Green Mediterranean Diet, rich in fruits and vegetables and low in animal products, is known to benefit heart health, but this new study shows that eating more plant-based foods and losing even a small amount of weight can help keep your brain young. That was the finding of a study that looked at the effects of diet and weight loss on brain aging and found that to reverse aging in the brain, choosing foods high in polyphenols and losing weight can benefit the brain. Want to stay young and sharp? Eat more plant-based foods and lose a small amount of weight.
