Diet and lifestyle have a significant impact on the brain and cognitive functions. An important role is played by the intestinal microbiota, which is connected to the brain via the microbiota-gut-brain axis. Intestinal dysbiosis is observed in people with mild cognitive impairment and Alzheimer’s disease. The factor affecting the intestinal microbiota is diet, in particular fiber, essential fatty acids, probiotics and also the appropriate supply of vitamins. Their deficiencies correlate with an increased risk of cognitive disorders and even Alzheimer’s disease. Nutritional education and support in a gradual lifestyle change should be the basic element of the prevention of cognitive disorders.
