A new study has determined that the wonderful Mediterranean diet reduces the risk of cognitive impairment. The research was published in the journal Alzheimer’s and Dementia.
Dementia is a term that refers to significant cognitive impairment, and usually occurs in adulthood. One of the most common diseases that cause dementia is Alzheimer’s.
The authors of the study relied on data that relate nutritional supplementation and ocular degeneration, a vision condition that worsens over the years. Nine thousand participants were recruited between 1992 and 2008. They used standardized tests to determine cognitive functioning and a questionnaire to determine the extent to which participants had followed a Mediterranean diet.
Thus, the study found that those who had adhered more strictly to a Mediterranean diet had reduced the risk of cognitive impairment. They also found that fish consumption benefits cognitive functioning.
The authors clarify that it was not taken into account whether participants who followed a Mediterranean diet had more physical activity, which can reduce health risks. However, it was clear that this diet contributes in some way to slowing cognitive decline.
What foods make up the Mediterranean diet?
This diet is based on the consumption of fresh and natural foods such as olive oil, fruits, vegetables, legumes, nuts, vinegar, cereals, fish, milk and cheese, avoiding industrialized products such as sausages, frozen and prefabricated food.
