This blog will only discuss anthocyanins but tune into Dr. Elvira de Mejia’s Free webinar, on March 15th at 10 am CDT to find out more about the health benefits of phytonutrients.Phytonutrients and Cardiovascular DiseaseTo register, visit the event page.Anthocyanins are flavonoids found in a large variety of foods. They are the most widely consumed flavonoid and are responsible for the beautiful red, purple, and blue coloring found in fruits, vegetables, grains, and flowers. Aside from coloring our plate, they provide a large array of health benefits such as protection against liver injuries, reduction of blood pressure, improvement of eyesight, suppression of proliferation of cancer cells, and cardiovascular disease prevention (Novotney 2012; Knczak and Zhang 2004). Anthocyanins have been used as traditional or folk medicine around the world. Only recently have we begun to research these health benefit claims.The role of anthocyanins in cardiovascular disease prevention is due to their protective oxidative stress properties. They are believed to act on different cells associated with the development of atherosclerosis. An Iowa Women’s Health Study of 34,489 postmenopausal women found that eating strawberries and blueberries just once per week was associated with a significant reduction in death from cardiovascular disease over a 14 year period (Mink et al., 2007). Similarly, a study of 93,600 healthy women from the Nurses’ Health Study II revealed a 34% lower risk of myocardial infarctions (heart attack) in women who consumed three servings of blueberries and strawberries per week (Cassidy et al., 2013). Additionally, anthocyanins have been shown to lower systolic blood pressure and arterial pressure, which can result in fewer cardiac events, such as a heart attack (Jennings et al., 2012).Anthocyanin-rich foods include:Asparagus (purple)BlackberriesBlack RiceBlueberriesConcord GrapesCranberriesEggplantPomegranatesPurple CornRaspberriesRed CabbageRed RadishesSweet CherriesThere are still several aspects of anthocyanins that require more research. Since anthocyanins are typically studied in fruit extracts, they are present in a combination of compounds and may not act independently. In fact, when anthocyanins are studied in combination with other compounds, rather than in isolation, the effects tend to be greater.Anthocyanin-containing foods are beautiful, delicious and nutritious.What are your favorites anthocyanin containing foods?Also, let us know what you would like to learn about anthocyanins and other bioactive compounds.
