A new study carried out on mice by researchers at the University of South Australia establishes a correlation between obesity and Alzheimer’s disease.
A new study shows that a diet high in fatty foods could not only impact your physique but also your brain. This research, led by neuroscientists at the University of South Australia, establishes a proven link between mice fed fatty foods for 30 weeks and an increase in their diabetes, a deterioration in their cognitive abilities and the development of anxiety, depression and Alzheimer’s disease.
NO to diets, YES to WW!
A link between obesity and Alzheimer’s disease
We then observe that “Obese people have about a 55% increased risk of developing depression, and diabetes will double that risk”, confirms Professor Assoc Bobrovskaya, co-author of the study. The study also shows that the100 million cases of people with obesity-related Alzheimer’s disease are expected to reach 100 million by 2050. “Obesity and diabetes impair the central nervous system, worsening psychiatric disorders and cognitive decline,” details Professor Assoc Bobrovskaya.
To arrive at this result, the researchers observed the mice’s data regarding food intake, body weight and glucose levels at different intervals. Tests for glucose and insulin tolerance and cognitive dysfunction were also performed. The mice fed the high-fat diet gained a lot of weight, developed insulin resistance, and began to behave abnormally compared to those fed the standard diet.
“Our results underscore the importance of tackling the global obesity epidemic. A combination of obesity, age and diabetes is very likely to lead to cognitive decline, Alzheimer’s disease and other mental health disorders.conclude the authors of the study.
