Research on the Sunflower



Sunflower, was historically a common crop among the Native American tribes. At the turn of the 19th century, Russian farmers were growing more than 2 million acres of sunflowers. Nutritionally, sunflowers are similar to nuts and provide a high content of monosaturated fat (oleic acid) and arginine (an amino acid). Despite the bad reputation associated with fat- it is necessary for optimal health. In moderate amounts, fat is a long term energy source for the body and provides insulation for vital organs and transportation for the fat soluble vitamins (A,E,D,K). Fat also supplies essential Fatty Acids (EFA) that the body cannot make. These compounds are necessary for growth, healthy skin, and hair, controlling blood pressure, and also blood clotting. Also EFAs enhance thermogenesis, help build muscle, prevent muscle break down, and speed recovery from fatigue.  Strengthen the immune system. EFAs make hormone-like eicosanoids that regulate immune and inflammatory responses; have anti-inflammatory effects and can slow autoimmune damage.

The sunflower kernel is rich in dietary fiber. The primary non-saccharides that are found in the kernel are primarily xylans, xyloglucans. All which work to provide pathways to lower blood cholesterol, and some research provides evidence that increased fiber diet intakes may reduce the incidence of cancer, hypertension, and obesity.

Sunflower kernels contain high levels of vitamin E, betaine, phenolic acids, and choline. The selenium content of the kernels is relatively high compared to other nuts and seeds. Selenium is important in maintaining neural functions and acts like an antioxidant.  In addition, the kernel is a good source of arginine and lignans.  Each of these compounds, while perhaps unfamiliar to the layperson, has been studied by the scientific community and shown to offer a variety of health benefits. Vitamin E (Tocopherols) and betaine, research shows this may they may protect against cardiovascular disease. The Phenolic acids act as antioxidants and anti-carcinogen. Choline plays a role in memory and cognitive function. Lignans: also may protect against heart disease and some cancers; lowers LDL cholesterol and triglycerides
