From today we have one more reason to follow a healthy, balanced diet that does not exceed in fat. In fact, a diet of this type not only increases the waistline but also the risk of developing insulin resistance, depression, anxiety and cognitive impairment. This is what emerges from a very recent scientific research published in the journal Metabolic Brain Disease by an Australian team from the University of South Australia (Xiong et al, Metabolic Brain Disease, 2022).
A high-fat diet also affects the brain, the study
The study took place in the laboratory on a population of mice. The mice were divided into two groups. The first group was given a healthy and balanced diet, the second group a diet rich in fat. The experiment lasted a month. By the end of this period, mice that had been fed a high-fat diet had significant weight gain, developed insulin resistance, a condition that can then open the door to type 2 diabetes, and also started behaving abnormally compared to those who had followed a balanced diet, showing anxiety, depression and cognitive impairment. Analyzing the situation, it emerged that obesity and diabetes act by unbalancing the central nervous system, exacerbating psychiatric disorders and cognitive decline.
The study shows that the association between obesity, diabetes and aging is an important risk factor for the development of dementia and Alzheimer's. Hence the importance of an active lifestyle and a healthy and balanced diet, trying to limit the intake of foods rich in refined sugars and fats. Perhaps now the risk of brain diseases seems so far away and we feel strong, but we are building our future health day by day, starting right now.
