Eating less helps improve memory

A slight reduction in diet in daily meals not only increases physical health, but also helps us to improve memory.

Many studies have shown that reducing the amount of calories taken into the body causes mice to live longer, reduce the risk of cardiovascular disease in humans and increase cognitive ability in older animals.

To see if reduced diets can help older people increase their memory capacity, a team of experts from Munster University (Germany) evaluated the ability to memorize short-term vocabulary of 50 elderly people with an average age of 60 degrees. tests. These people are above average weight compared to many people of the same age, but not yet obese.

The team divided volunteers into two groups and asked for a 30% reduction in the amount of calories they take into their bodies every day. 3 months later, all volunteers were asked to complete short-term memory tests for vocabulary again.

The results showed that the number of words that people who reduced their diets remembered was 20% more than the first time. Specifically, the first time each person remembers 10.5 words for the first time and 12.5 words for the second time.

"Remembering two more words is not too big for young people, but for people in their fifties and older, it means a lot," said Agnes Floel, the lead researcher.

Meanwhile, the number of words that the other group remembers cannot change.

Agnes said that the levels of glucose and insulin in the body of people with reduced diets were much lower than before the test. Some previous studies have confirmed that neurons work better when glucose and insulin are reduced.
