New research suggests that sticking to a consistent eating routine for more than two decades could potentially delay the aging process in the brain. Scientists have found that following this prolonged dietary pattern may help mitigate certain expected metabolic changes associated with conditions like Alzheimer’s disease.
A recent study conducted by Boston University in the US focused on 10 male monkeys divided into two groups. One group followed a regular, balanced diet, while the other group consumed around 30% fewer calories for the duration of their lives.
After the monkeys passed away naturally, researchers examined their brain tissue using single-nuclei RNA sequencing. The results indicated that brain cells of the calorie-restricted group exhibited better metabolic health and functionality compared to those on a standard diet.
Although these findings are based on animal studies, experts believe that there are significant parallels between monkey and human brains in terms of basic structure and connectivity. The study team suggests that sustained dietary modifications may impact the aging process of the brain at a cellular level.
Ana Vitantonio, the lead author and a fifth-year PhD student, emphasized the potential of calorie restriction in slowing down biological aging and reducing age-related metabolic changes, especially in more complex species like monkeys.
Co-author Professor Tara L. Moore highlighted the importance of these cellular alterations in relation to cognitive functions and learning. Long-term calorie restriction could potentially slow down certain aspects of brain aging, according to the study’s findings.
This research adds to the existing body of knowledge supporting the benefits of calorie restriction. In regions like Okinawa, Japan, known for longevity, residents practice the ‘80% trick,’ which involves consuming one small meal in the late afternoon or early evening and stopping when they are 80% full.
Dr. Deborah Lee, a GP, advocates for mindful eating and emphasizes the potential health benefits of this approach. She encourages avoiding processed foods and opting for plant-based, whole foods to promote overall well-being and longevity.
