Scientists at Virginia Tech University have discovered that some types of super-processed foods are harmful to the brain. This was reported in a study published in The American Journal of Clinical Nutrition.
The results of the study showed that processed meat products and sugary non-alcoholic beverages, especially in elderly people, are more strongly associated with a decrease in cognitive ability compared to other foods.
For seven years, researchers monitored the health of more than 5,000 Americans over 55 years old, analyzed their daily diets, and tested their memory and thinking abilities through special tests.
It turns out that consuming at least one portion of processed meat per day increases the risk of memory problems by 17%, while each soda affects another 6%. Those who regularly consumed both foods significantly accelerated cognitive decline.
The authors note that these foods were the main risk factors, while other ultra-processed products did not have a significant impact on the brain. Scientists recommend consuming less processed meat, cooking at home, and replacing carbonated water with regular drinking water. According to them, simple changes in diet reduce the risk of early cognitive decline and the development of dementia.
