Benefits of Mediterranean Diet

This diet provides polyphenols and dietary fiber. Polyphenols are strong antioxidants that protect the body against free radicals, which cause oxidative stress.

Dietary fibers improve gut health and promote digestion. Polyphenols in the Mediterranean diet may also promote the growth of gut bacteria and prevent flatulence and constipation.

This diet can reduce blood glucose levels and improve levels of HbA1C (glycosylated hemoglobin), a biomarker used to measure the risk of type 2 diabetes.
