Sunflower Seeds Nutrition Facts

Sunflower seeds are packed with essential macro- and micronutrients that your body needs to function optimally. Here’s a closer look at the nutrients found in sunflower seeds per one ounce of dry-roasted, unsalted sunflower seed kernels, according to the U.S. Department of Agriculture (USDA) database.


Sunflower seeds are a great source of energy. One ounce of sunflower seeds contains 165 calories, 5.5 grams of protein, 7 grams of total carbohydrates, and 14 grams of fat. The fat content is mostly unsaturated, with 3 grams of monounsaturated fat and 9 grams of polyunsaturated fat. Sunflower seeds also contain 3 grams of fiber, which can help you feel full and satisfied.


Sunflower seeds are also rich in micronutrients that your body needs to stay healthy. One ounce of sunflower seeds contains 2 milligrams of niacin (13% DV), 2 milligrams of pantothenic acid (40% DV), 0.2 milligrams of vitamin B6 (15% DV), and 67 micrograms of folate (17% DV). Sunflower seeds are also a great source of vitamin E, with 7.4 milligrams per ounce (49% DV).

It’s worth noting that one ounce of sunflower seeds only contains 1 milligram of sodium, which is 0% of the daily value (DV). So, if you’re looking for a low-sodium snack, sunflower seeds are a great option.

Overall, sunflower seeds are a nutrient-dense food that can provide your body with a range of essential vitamins and minerals. Incorporating sunflower seeds into your diet is a great way to support your overall health and wellbeing.

Health Benefits of Sunflower Seeds

When it comes to snacking, sunflower seeds are a healthy and satisfying option that offer a variety of health benefits. Here are seven ways that incorporating sunflower seeds into your diet can improve your health:

1. Promotes Heart Health

Consuming unsalted sunflower seeds can be beneficial for heart health due to their cholesterol-free and high-fiber content. The soluble fiber in sunflower seeds can help lower blood cholesterol levels by binding to dietary cholesterol in the small intestine and preventing it from being absorbed into the bloodstream. Additionally, sunflower seeds contain linoleic acid, an unsaturated fat that promotes blood vessel relaxation and lower cholesterol levels.

2. Supports Thyroid Health

Sunflower seeds are an excellent source of selenium, a mineral that supports thyroid health. Research has shown that low levels of selenium can increase the risk of developing certain thyroid disorders.

3. Encourages Metabolic Health

Sunflower seeds contain fiber, protein, and healthy fats that support metabolic health. These nutrients help slow down digestion and regulate blood sugar levels, making them particularly beneficial for individuals with type 2 diabetes. Additionally, sunflower seeds can increase feelings of fullness, making them a smart snack or meal addition.

4. Strengthens Immune Health

Sunflower seeds are packed with immune-boosting nutrients such as selenium, zinc, vitamin E, copper, and plant compounds. These micronutrients act as antioxidants, reducing inflammation and protecting against disease-causing free radicals.

5. Boosts Digestive Health

Sunflower seeds are a gut-healthy food that contains both insoluble and soluble fiber. Soluble fiber acts as a prebiotic, feeding the healthy bacteria in your gut microbiome and supporting digestive regularity. A healthy gut microbiome is closely linked to several aspects of health, including immunity and brain health.

6. Facilitates Growth, Development, and Repair

Sunflower seeds are a cholesterol-free source of protein that helps build and maintain muscle. Protein is also a structural component of nearly every vital structure in the body, and it speeds up wound- and tissue-healing. Additionally, zinc and folate in sunflower seeds are essential during pregnancy to promote healthy growth and development of the baby.

7. Bolsters Skin Health

The healthy fats and vitamin E in sunflower seeds nourish glowing, healthy skin. These nutrients offer anti-inflammatory benefits for the skin, while vitamin E provides protection against harmful UV light rays.

Incorporating sunflower seeds into your diet can provide a variety of health benefits. However, it is important to consume them in moderation, as one ounce of sunflower seeds at a time is recommended for optimal health benefits. Choose unsalted varieties to avoid excessive sodium intake, and enjoy them as a snack or meal addition to support your overall health and well-being.

Who Should Avoid Sunflower Seeds?

While sunflower seeds offer a range of health benefits, there are certain groups that may need to avoid them.

If you suffer from sunflower seed allergies, it is best to avoid them altogether. Although sunflower seed allergies are less common than peanut and tree nut allergies, they do exist.

Sunflower seeds are higher in calories, and salted sunflower seeds can contain a lot of sodium. Overdoing it on salted sunflower seeds may result in difficulty managing blood pressure levels in those with hypertension.

Excessive consumption of sunflower seeds may also lead to too much cadmium intake. Sunflowers absorb cadmium from the soil while growing, and consuming copious amounts of sunflower seeds (upwards of 5 to 10 ounces, four or more times per week) may result in a high cadmium intake.

Tips for Buying Sunflower Seeds

When shopping for sunflower seeds, consider purchasing unsalted varieties to moderate sodium intake. Opt for sprouted sunflower seeds if possible, as sprouting can increase nutrient bioavailability. Whether or not to purchase sunflower seeds with their inedible hulls intact is a personal preference, but be cautious not to swallow them when consuming. Keep an eye out for any added flavors or ingredients that may affect the nutritional value of the seeds.

Incorporating Sunflower Seeds Into a Healthy Routine

Sunflower seeds are a versatile and delicious addition to any healthy routine. Here are some ideas to get you started:

  • Mix sunflower seeds into homemade trail mix, granola, or granola bars for a satisfying snack on-the-go.
  • Add them to baked goods like desserts and bread for a crunchy texture and nutty flavor.
  • Use sunflower seeds to top cereal, oatmeal, or yogurt bowls for added protein and crunch.
  • Incorporate them into chicken or tuna salad for a unique twist on a classic dish.
  • Roast vegetables with sunflower seeds for a flavorful and nutritious side dish.
  • Toss them into pastas, casseroles, and salads for added texture and flavor.
  • Grind sunflower seeds into breading for proteins for a gluten-free and nut-free alternative.
  • Enjoy them straight out of the bag for a quick and satisfying snack.

Additionally, sunflower seeds can be made into sunflower butter, which serves as a great nut-free alternative for school lunches. Incorporating sunflower seeds into your healthy routine is an easy and delicious way to add nutrition and variety to your meals.
