Recent research from the National Library of Medicine show that blueberries offer important health benefits, mainly because they are rich in anthocyanas. The consumption of blueberries regularly is linked to lower risks of heart disease, type 2 diabetes and obesity. They also help improve the function of blood vessels and protect the brain. Clinical and observational studies show better cholesterol, blood pressure and insulin sensitivity after eating blueberries. In addition, blueberries have a positive effect on intestinal bacteria and reduce inflammation, which helps prevent chronic diseases.
