Mediterranean diet improves gut microbiome
A Mediterranean diet can increase the number of beneficial gut bacteria that are associated with healthy aging. Changes in the microbiome have contributed to lower levels of markers of inflammation in the body.

A Mediterranean diet can increase the number of beneficial gut bacteria that are associated with healthy aging. This was shown by a five-year study published in the journal Gut.
Research has shown that the Mediterranean diet reduces the body's production of inflammatory mediators that contribute to impaired cognitive function. It can help prevent diabetes, cancer and atherosclerosis. Scientists attribute these effects to changes in the gut microbiota caused by healthy food.
Scientists analyzed the gut microbiome of 612 people aged 65 to 79 years before the experiment and one year after it began. Half of the study participants ate as usual, while the other switched to a Mediterranean diet. The latter is high in fruits, vegetables, legumes, nuts, fish, olive meat, and small amounts of red meat and saturated fat.
In people who ate the Mediterranean diet for 12 months, scientists have found changes in the gut microbiota. They showed an increase in bacterial growth, which is associated with a decrease in the level of senile asthenia (muscle weakness, slow gait), improved brain function (memory), and a decrease in the concentration of inflammatory mediators in the blood.
More detailed analysis showed that the Mediterranean diet increased the number of bacteria that can produce beneficial short-chain fatty acids and decreased the number of bacteria that are involved in the synthesis of substances associated with the risk of bowel cancer, diabetes and liver obesity.
Scientists point out that these changes were caused by an increase in the amount of fiber, vitamins (C, B6, B9) and minerals (copper, potassium, iron, magnesium and manganese) in the diet.
The effects of the diet were independent of the person's age and weight. Although there were significant differences in the microbiome of the participants before the study, after 12 months the Mediterranean diet had a similar effect on each of them.
