Fresh mulberries have about 10% carbs in the form of simple sugars, starch, and soluble and insoluble fibers. They’re fairly high in water and low in calories. They contain high amounts of both iron and vitamin C, as well as decent amounts of potassium and vitamins E and K.
Mulberries contain several plant compounds, such as anthocyanins, chlorogenic acid, rutin, and myricetin. Deep-colored and mature berries are richer in these compounds than colorless berries. They may lower cholesterol levels, help prevent fatty liver disease, and improve blood sugar control. They also decrease oxidative stress, which may reduce cancer risk.
