Sunflower Seeds


Sweet, nutty sunflower seeds are an excellent source of essential fatty acids, vitamins, and minerals. Sunflower kernels actually employed to extract edible oil at commercial levels. Besides being eaten as popular snacks, they are also used in the kitchen to prepare variety of recipes.

Sunflower is a tall, erect, herbaceous annual plant, whose botanical name is Helianthus annuus. It is native to Middle American region from where it spread as an important commercial crop all over the world through the European explorers. Today, Russia, China, USA, and Argentina are the leading producers of sunflower crop.

Growing Sunflower:

Sunflower flourishes well under well-drained moist, limey soil. It prefers good sunlight. Domesticated varieties bear single large flower-head (Pseudanthium) at the top. Unlike its domestic cultivar type, wild sunflower plant exhibits multiple branches with each branch carrying its own individual flower-head. The sunflower head consists of two types of flowers. While its perimeter consists of sterile, large, yellow petals (ray flowers), the central disk is made up of numerous tiny fertile flowers arranged in concentric whorls, which subsequently convert into achenes (edible seeds).

Sunflower seeds are about 6 mm to 10 mm in length and feature conical shape with smooth surface. Their black outer coat (hull) encloses single, gray-white edible-kernel inside. Each sunflower head may hold several hundreds of edible oil seeds.

In the farm fields, sunflower heads can be ready for harvesting once they turn brown and dry. In general, the seeds intended to use in confectionery are somewhat larger, sweet, and have striped hulls. Oil-type sunflower seeds are characterized by small size, have more oil content, and feature black hulls. However, both types of seeds can be used for either purposes.

Culinary Uses:

At present, sunflower seeds are used mainly to press cooking oil. They are still favored in the confectionery, and as bird feed. As in pumpkin seeds, sunflower seeds too are popular, tasty, low-fat snack item.

Here are some serving tips:

  • Roasted and salted, they can be enjoyed as a healthy snack.
  • They add crunchiness to salads.
  • Sprinkle sunflower kernels over fried-rice dishes or sautéed vegetables as garnish.
  • The seeds can be coated with chocolate, candied, or added in cakes, and muffins.
  • The seeds can be added to salad dressings, casseroles or baked goods.
  • In Germany and other Central European regions, the flour made from the seeds is used in making dark bread,sonnenblumenbrot (sunflower bread).
  • Sunflower seed butter, sold as SunButter, is a suitable alternative in peanut allergics.

Health Benefits of Sunflower Seeds:

  • Delicious, nutty, and crunchy sunflower seeds are widely sunflower seeds nutritional values 2considered as healthful foods. They are high in energy; 100 g seeds hold about 584 calories. Nonetheless, they are one of the incredible sources of health benefiting nutrients, minerals, antioxidants and vitamins.
  • Much of their calories come from fatty acids. The seeds are especially rich in poly-unsaturated fatty acid linoleic acid, which constitute more 50% fatty acids in them. They are also good in mono-unsaturated oleic acid that helps lower LDL or “bad cholesterol” and increases HDL or “good-cholesterol” in the blood. Research studies suggest that Mediterranean diet which is rich in monounsaturated fats help to prevent coronary artery disease, and stroke by favoring healthy blood lipid profile.
  • Like in other nuts, they too are a very good source of proteins loaded with fine quality amino acids such as tryptophan that are essential for growth, especially in children. Just 100 g of seeds provide about 21g of protein (37% of daily-recommended values).
  • In addition, sunflower seeds contain health benefiting poly-phenol compounds such as chlorogenic acid, quinic acid, and caffeic acids. These compounds are natural anti-oxidants, which help remove harmful oxidant molecules from the body. Further, chlorogenic acid helps reduce blood sugar levels by limiting glycogen breakdown in the liver.
  • The seeds are a very rich source of vitamin E; contain about 35.17 g per 100 g (about 234% of RDA). Vitamin E is a powerful lipid soluble antioxidant, required for maintaining the integrity of cell membrane of mucus membranes and skin by protecting it from harmful oxygen-free radicals.
  • Sunflower kernels are one of the finest sources of B-complex group of vitamins. They are very good sources of B-complex vitamins such as niacin, folic acid, thiamin (vitamin B1), pyridoxine (vitamin B6), pantothenic acid, and riboflavin.
  • Sunflowers are incredible sources of folic acid. 100 g of kernels contains 227 µg of folic acid,which is about 37% of recommended daily intake. Folic acid is essential for DNA synthesis. When given in anticipant mothers during the peri-conceptional period, it may prevent neural tube defects in the baby.
  • Niacin and pyridoxine are other B-complex vitamins found abundantly in the sunflower seeds. About 8.35 mg or 52% of daily-required levels of niacin is provided by just 100 g of seeds. Niacin helps reduce LDL-cholesterol levels in the blood. In addition, it enhances GABA activity inside the brain, which in turn helps reduce anxiety and neurosis.
  • The seeds are incredibly rich sources of many essential minerals. Calcium, iron, manganese, zinc, magnesium, selenium, and copper are especially concentrated in sunflower seeds. Many of these minerals play a vital role in bone mineralization, red blood cell production, enzyme secretion, hormone production, as well as in the regulation of cardiac and skeletal muscle activities.

Just a handful of sunflower kernels a day provides much of the recommended level of phenolic anti-oxidants, minerals, vitamins, and protein.

Take Caution:

In some susceptible individuals, however, its reactions may include itchiness of the skin, sneezing, itchiness in the eyes, gastritis, vomiting, etc. It is advised, therefore, to avoid the use of seeds in known allergic persons.
