Sunflower Seeds Nutrition Facts

Well-loved from birds to baseball players, sunflower seeds are a great snack to munch on, with their irresistible flavor and satisfying crunch. They’re also an excellent ingredient for appetizers, salads, desserts and other dishes.

Aside from their taste and texture, sunflower seeds are notable for their nutritional content. Read on to learn more about the benefits and uses of sunflower seeds, and how you can cook them at home.

What Are Sunflower Seeds?

Sunflower seeds, despite their name, are technically not seeds — they’re actually the fruit of the sunflower plant.1 Known for its vibrant yellow color, a sunflower plant can grow up to 20 feet tall, with a flower head that can reach up to 30 inches in diameter.2

The center of the flower head is studded with tear-shaped “seeds” that come in a black or striped gray-green color.3 The outer part of the sunflower seed is known as the pericarp or hull, whereas the inner part is called the kernel.4 The kernel, which is the edible part of the sunflower seed, has a slightly nutty flavor and a firm, yet tender texture.5

Sunflower seeds are sold raw, dried, roasted or flavored, with or without their hull. The world’s leading producers of sunflower seeds are Russia, Spain, Argentina, France, China and Peru. In the U.S., the states that produce the highest amount of sunflower seeds are North Dakota, Minnesota and California.6

Where Do Sunflower Seeds Come From?

As mentioned above, sunflower seeds come from the center of flower head of a sunflower plant. However, not all sunflower seeds are the same, as they’re categorized according to the sunflower hybrid that they’re harvested from. The two varieties of sunflower hybrids are known as the oilseed type and the non-oilseed type.

Seeds from non-oilseed type are also called confectionery sunflower seeds. They are characterized by their larger size and striped hulls, and are primarily grown for human consumption or used in birdseed mixes.

Alternatively, oilseed type sunflowers produce small solid black seeds that are primarily used to produce vegetable oil. These seeds are also called black oil sunflower seeds. They can be further divided into three categories according to their fatty acid profiles: standards or linoleic, NuSun or mid-oleic, and high oleic.7

Sunflower seeds are harvested once the back of the flower heads turn pale yellow and their edges turn to brown. The seeds, which are initially white, will also darken once they’re ready for harvesting. The buds on each seeds will dry up and fall off as well to expose their full surface. Harvesting sunflower seeds at the right time is important to ensure that they have larger kernels and better nutritional value.8

Health Benefits of Sunflower Seeds

Sunflower seeds are a rich source of phenolic acids and flavonoids, which contribute to their medicinal properties, including:9

Antioxidant

Antimicrobial

Antidiabetic

Anti-inflammatory

Antihypertensive

Antiviral

They‘re also an excellent source of the following vitamins and minerals:10

  • Vitamin E (alpha tocopherol) — Alpha tocopherol may help protect your cells against free radical damage by inhibiting the production of reactive oxygen species (ROS). As a result, it lowers your risk of chronic diseases such as cancer, arthritis and cataracts. It may also help inhibit inflammation and promote healthy immune function.11
  • Thiamin — Also known as vitamin B1, thiamine plays a role in energy production, muscle contraction and transmission of nerve signals.12
  • Vitamin B6 — It plays a role in protein metabolism and is involved in more than 100 enzyme reactions in the body.13 It’s also linked to a lower risk of cardiovascular disease and stroke, premenstrual syndrome, and morning sickness during pregnancy.14
  • Magnesium — It helps promote brain and heart health, support detoxification, maintain healthy cellular function, and optimize your mitochondria. It may also help slash your risk for heart failure, stroke, diabetes and even all-cause mortality.
  • Selenium — An essential mineral that provides antioxidant, antiviral and anticancer properties, selenium may help reduce your risk of heart disease, asthma and human immunodeficiency virus (HIV).

Other vitamins and minerals in sunflower seeds include niacin, riboflavin, folate, copper, manganese, phosphorus, iron, calcium and zinc.15 They also contain sulfur-rich proteins that may be useful for various human metabiological processes such as insulin production and muscular and skeletal development.16

Do You Know How to Eat Sunflower Seeds?

Sunflower seeds that are sold without shells can be eaten as is, but what about those that still have hulls? While it may be fun to crack the sunflower seeds using your teeth and spit out the hulls, this technique is not suitable if you’re planning to use the kernels for a recipe, and it may damage your teeth over time.17 Here’s how to remove the shells from sunflower seeds the easy way, according to Leaf:18

  • Fill a reusable bag with a half cup of sunflower seeds, making sure they’re in a single layer.
  • Seal the bag and slowly roll a rolling pin over the seeds. Exert a bit of force to crack their hulls.
  • Pour the contents of the bag in a bowl of water to separate the hulls from the kernels. The hulls will float at the surface of the water while the kernels sink to the bottom.
  • Remove the shells from the surface of the water using your hands or using a skimmer or slotted spoon.
  • Drain the water from the bowl and remove the kernels. Once they’ve dried, they’re ready to be eaten or used in cooking.

How to Bake With Sunflower Seed Meal: Tips to Keep in Mind

Sunflower Seed Side Effects You Should Know About

Despite their wide array of health benefits, sunflower seeds are not without a few side effects. First off, consuming excessive amounts of sunflower seeds in one sitting may lead to unwanted weight gain, as it makes you more prone to exceeding your daily calorie needs.29

You should also consider food sensitivities before consuming sunflower seeds, as they may cause allergic reactions such as breathing difficulties, swelling of the pharynx, retention of saliva, and swelling of the mouth and tongue.30

Is Sunflower Seed Oil as Good for Your Health as Sunflower Seeds?

Sunflower seeds are primarily cultivated for the extraction of sunflower seed oil. While the seeds of the sunflower plant are good for you because they’re in whole form, its oil is a different story. I don’t recommend consuming sunflower seed oil because of its high omega-6 fatty acid content, which could disrupt the balance of omega-3 to omega-6 fatty acids in your body.

Excessive consumption of omega-6 fatty acids may put you at higher risk of chronic diseases like obesity, Type 2 diabetes, rheumatoid arthritis, cardiovascular disease, macular degeneration, asthma, inflammatory bowel disease and cancer. If you’re looking for healthy alternatives to sunflower oil for foods, try using extra virgin coconut oil.

Choosing and Storing Sunflower Seeds

When buying sunflower seeds, make sure to purchase from a trusted organic brand. This can guarantee that they’re not contaminated with potentially harmful agricultural chemicals. You should also choose seeds that are not broken and limp. Avoid seeds that are yellow in color, as they may have already turned rancid. To improve the shelf life of your sunflower seeds, store them in an airtight glass container and keep them in the fridge. Shelled sunflower seeds may last longer than hulled seeds.31
