Eating low-calorie foods can have a protective effect against certain diseases because the number of calories that a person eats directly influences the performance of different cells, say the researchers.
The study on mice has shown that a low-calorie diet can protect the brain from neuronal death associated with diseases such as Alzheimer's disease, Parkinson's disease, epilepsy and Stroke.
"We are examining how diet changes affect metabolism and, ultimately, the chances of developing diseases associated with aging," said co-author Alicia Kowaltowski, a professor at the University. from Sao Paulo to Brazil.
For the study presented at the London FAPESP Week on February 11 and 13, the research team divided the mice into two groups.
They calculated the average number of calories consumed by the group without any caloric restriction, then gave the other group 40% fewer calories.
After 14 weeks, mice in both groups received an injection containing a substance known to cause convulsions, lesions and death of neuronal cells.
The researchers found that while group members who did not have dietary restrictions had epileptic seizures, those with limited calories did not.
