Mulberries contain high amounts of both iron and vitamin C, as well as decent amounts of potassium and vitamins E and K. They 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.
Mulberry allergy is rare, but people sensitive to birch pollen may experience allergic reactions to mulberries.
