Sunflower seeds are an excellent source of vitamin E, the body's primary fat-soluble antioxidant. Vitamin E travels throughout the body neutralizing free radicals that would otherwise damage fat-containing structures and molecules, such as cell membranes, brain cells, and cholesterol. By protecting these cellular and molecular components, vitamin E has significant anti-inflammatory effects that result in the reduction of symptoms in asthma, osteoarthritis, and rheumatoid arthritis, conditions where free radicals and inflammation play a big role. Vitamin E has also been shown to reduce the risk of colon cancer, help decrease the severity and frequency of hot flashes in women going through menopause, and help reduce the development of diabetic complications.

In addition, vitamin E plays an important role in the prevention of cardiovascular disease. Vitamin E is one of the main antioxidants found in cholesterol particles and helps prevent free radicals from oxidizing cholesterol. Only after it has been oxidized is cholesterol able to adhere to blood vessel walls and initiate the process of atherosclerosis, which can lead to blocked arteries, heart attack, or stroke. Getting plenty of vitamin E can significantly reduce the risk of developing atherosclerosis. In fact, studies show that people who get a good amount of vitamin E are at a much lower risk of dying of a heart attack than people whose dietary intake of vitamin E is marginal or inadequate. Just a quarter-cup of sunflower seeds contains 90.5% of the daily value for vitamin E.

Sunflower seeds are the gift of the beautiful sunflower, a plant with rays of petals emanating from its bright yellow, seed-studded center. The sunflower's Latin scientific name, Helianthus annuus, reflects its solar appearance since helios is the Greek word for sun, and anthos is the Greek word for flower.

The sunflower produces grayish-green or black seeds encased in tear-dropped shaped gray or black shells that oftentimes feature black and white stripes. Since these seeds have a very high oil content, they are one of the main sources used to produce polyunsaturated oil. Shelled sunflower seeds have a mild nutty taste and firm, but tender texture. Their taste is oftentimes compared with the Jerusalem artichoke (not to be confused with the bulb artichoke), another member of the Helianthus family.

If you want to remove the shells from unshelled sunflower seeds, there are easier ways to remove the shell than by hand, which requires a lot of diligence and time. The quickest way to shell sunflower seeds is to grind them in a seed mill and then place them in cold water where the shells will float to the top and can be skimmed off with a slotted spoon.

While not as efficient, another alternative for those who don't have seed mills (which is probably the majority of us) is to put a small amount of seeds into the bowl of an electric mixer, pulsing the mixer on and off a few times for a few seconds each time, until the shells separate but not too many seeds are crushed. Then plunge the seeds into cold water as described above to separate them from the shells. However, shelled sunflower seeds are plentiful in the stores so there is no need to go through the trouble unless you have harvested them from your garden.
