The ketogenic diet can improve cerebral blood flow and slow cognitive decline in people over 50, a study involving 11 volunteers has shown.
In the experiment, participants switched to a diet where over 70% of calories came from fats with minimal carbohydrate content. For 20 days, specialists assessed the state of cerebral circulation. After just three weeks, the average increase in blood flow to the brain was 22%. Indirect signs of activated metabolic processes in neurons were also identified, according to progorod59.
Researchers hypothesized that in a state of ketosis, brain cells begin to more effectively use ketone bodies as an energy source, which enhances their resilience and recovery. The study organizers noted the potential benefits of such a diet for preventing age-related cognitive disorders but stated the need for large-scale clinical trials. They recommended transitioning to a ketogenic diet only under medical supervision, especially for individuals with chronic diseases.
Previously, ABN24 reported that cardiologist Maria Chaikovskaya named the Mediterranean diet as the safest for people with heart disease. This dietary system is based on vegetables, fruits, fish, seafood, and olive oil.
