One ounce of dry roasted sunflower kernels gives you 3.1 grams of fiber and 49% of your daily vitamin E. Few snacks pack both into a handful that costs about 165 calories.
So yes, sunflower seeds fiber is real, landing close to pistachios and a little behind almonds. The bigger surprises are in the vitamins and minerals, and in how much salt some sunflower snacks carry.
Sunflower seeds fiber by amount
USDA FoodData Central lists dry roasted, unsalted sunflower kernels at 11.1 grams of fiber per 100 grams. That figure is for the kernels alone, not the striped shells.
| Amount (kernels) | Fiber | % DV (28 g) | Calories |
|---|---|---|---|
| 1 tablespoon (about 8 g) | 0.9 g | 3% | 47 |
| 1 ounce (28 g) | 3.1 g | 11% | 165 |
| 1/4 cup (32 g) | 3.6 g | 13% | 186 |
| 100 grams | 11.1 g | 40% | 582 |
A tablespoon sprinkled on a salad adds almost a gram of fiber. A quarter cup, about what many bag labels list as a serving, gives you a solid 3.6 grams.
The carbohydrate count is modest, at 6.8 grams per ounce, and almost half of it is fiber. Sugar is under a gram unless the seeds are coated or sweetened.
Sunflower kernel nutrition: the vitamin E seed
Sunflower kernels are one of the richest everyday sources of vitamin E, a fat soluble antioxidant. An ounce of dry roasted kernels brings:
- Vitamin E: 7.4 mg, about 49% of the Daily Value
- Copper: 0.52 mg, about 58% DV
- Selenium: 22.5 mcg, about 41% DV
- Phosphorus: 327 mg, about 26% DV
- Manganese: 0.6 mg, about 26% DV
- Folate: 67 mcg, about 17% DV
- Zinc: 1.5 mg, about 14% DV
- Vitamin B6: 0.23 mg, about 14% DV
Protein comes in at 5.5 grams per ounce, close to almonds and pistachios. Fat is 14 grams, most of it polyunsaturated, with only about 1.5 grams saturated.
That makes sunflower kernels an all rounder. They’re not the top seed for fiber, but they cover fiber, protein, vitamin E and selenium better than most single snacks.

Raw or roasted: which kernels give more fiber?
Raw and roasted kernels look almost identical in the bag, but USDA lists them a little differently. Raw, dried kernels come in at 8.6 grams of fiber per 100 grams, which works out to about 2.4 grams per ounce.
Dry roasted kernels list 11.1 grams per 100 grams. The two records come from different samples and lab analyses, so read the gap as a ballpark rather than proof that roasting adds fiber. Either way, an ounce of kernels lands somewhere between 2.4 and 3.1 grams.
| Per ounce (28 g) | Raw kernels | Dry roasted kernels |
|---|---|---|
| Fiber | 2.4 g | 3.1 g |
| Calories | 166 | 165 |
| Protein | 5.9 g | 5.5 g |
| Vitamin E | 10.0 mg (67% DV) | 7.4 mg (49% DV) |
| Selenium | 15.0 mcg (27% DV) | 22.5 mcg (41% DV) |
In these USDA records, raw kernels win on vitamin E, while roasted kernels edge ahead on fiber and selenium.
The differences are small enough that taste should decide. Raw kernels work well blended into pesto or soaked into overnight oats, while roasted ones bring more crunch to salads and trail mix.
How far a handful goes toward your daily fiber
Mayo Clinic puts daily fiber needs at about 21 to 25 grams for women and 30 to 38 grams for men. The label Daily Value is a flat 28 grams.
Against those numbers, one ounce of roasted kernels covers roughly 12 to 15% of a woman’s target and about 8 to 10% of a man’s. That’s a meaningful slice for a snack you can eat in a couple of minutes.
Where sunflower seeds really help is as a topping. A tablespoon on lunch and another on dinner adds almost 2 grams without changing either meal much, and those small additions are how most people close the gap to their target.
How sunflower seeds compare
Among seeds, sunflower kernels sit in the middle for fiber. Among nuts, they hold their own with the better options.
| Seed or nut (1 oz) | Fiber | Protein | Calories |
|---|---|---|---|
| Chia seeds | 9.8 g | 4.7 g | 138 |
| Flaxseed | 7.7 g | 5.2 g | 151 |
| Pumpkin seeds, whole roasted | 5.2 g | 5.3 g | 126 |
| Almonds | 3.5 g | 6.0 g | 164 |
| Sunflower kernels, dry roasted | 3.1 g | 5.5 g | 165 |
| Pistachios | 3.0 g | 5.7 g | 159 |
| Walnuts | 1.9 g | 4.3 g | 185 |
| Hemp hearts | 1.1 g | 9.0 g | 157 |
Chia and flax carry two to three times as much fiber, but they’re usually eaten by the spoonful rather than the handful. Sunflower kernels are easier to snack on, and that makes their 3.1 grams per ounce more practical for many people.
Compared with walnuts, sunflower kernels give you about 60% more fiber and more protein for fewer calories. Compared with hemp hearts, they trade some protein for nearly three times the fiber.
Kernels, in shell, honey roasted or butter
Sunflower seeds come in more forms than most seeds, and the fiber and salt shift with each one.
| Form | Serving | Fiber | Sodium | Note |
|---|---|---|---|---|
| Dry roasted kernels, unsalted | 1 oz | 3.1 g | 0 mg | The baseline |
| Honey roasted kernels | 1/4 cup (32 g) | 3 g | 75 mg | 2 g added sugar |
| Sunflower seed butter | 2 Tbsp (32 g) | about 1.8 g | varies | Often sweetened |
| In shell, dry roasted, salted (kernels) | 1 oz kernels | 2.6 g | about 1,700 mg | Salt coats the shells |
Honey roasted kernels keep most of the fiber and add only a little sugar. Sunflower seed butter is a different story: USDA’s record lists about 5.7 grams of fiber per 100 grams, roughly half the fiber of plain kernels, along with 10.5 grams of sugar per 100 grams, which points to added sweetener in many jars.
The in shell, salted seeds are the real outlier, and we’ll come back to them at the end.
Building healthy snacks with sunflower seeds
Sunflower kernels are mild, crunchy and cheap, which makes them easy to add almost anywhere. A few ideas that lift the fiber further:
- Toss a quarter cup into a bowl of cooked lentils or black beans for a crunchy grain free salad.
- Mix an ounce with a cup of raspberries for an 11 gram fiber snack.
- Stir a tablespoon into oatmeal along with a tablespoon of chia seeds.
- Swap croutons for toasted kernels on soups and salads.
- Make a trail mix of sunflower kernels, pumpkin seeds and a few dried apricots.
The raspberry pairing is a good example. A cup of raspberries brings 8 grams of fiber, and an ounce of kernels adds 3.1, so the snack covers about 40% of the Daily Value.
The lentil salad works the same way on a bigger scale. Half a cup of cooked lentils has 7.8 grams of fiber, and a quarter cup of kernels brings 3.6 more, for about 11.4 grams in one bowl.
For the trail mix, half an ounce each of sunflower kernels and whole roasted pumpkin seeds gives you about 4.2 grams of fiber. Pumpkin seeds carry more fiber, while sunflower kernels bring the vitamin E, so the two cover each other’s gaps.
If you need to avoid peanuts or tree nuts, sunflower kernels are an easy swap in snacks and spreads, and the fiber story barely changes for you. An ounce of peanuts has 2.4 grams of fiber, a little less than the same weight of roasted sunflower kernels.

A quick label checklist for sunflower snacks
- Look for kernels with only sunflower seeds, or seeds and a little salt, on the ingredient list.
- Check sodium per serving. Unsalted kernels read 0 mg, while salted versions vary widely.
- With in shell seeds, check whether the serving size refers to the whole seed or just the kernels.
- For sunflower butter, look for 0 grams of added sugar and at least 2 grams of fiber per serving.
- Watch flavored seeds such as ranch or barbecue, which often add more salt than you’d expect.
- Store opened bags in a cool, dark place or the fridge, since the polyunsaturated fats can go stale.
If you’re adding more seeds to raise your fiber, Mayo Clinic recommends doing it gradually and drinking plenty of fluids so your digestion can keep up.
The catch with in shell sunflower seeds
The ballpark style seeds you crack with your teeth are where sunflower seeds stop being a simple healthy snack. USDA’s record for salted, dry roasted seeds from the shell lists about 1,700 mg of sodium per ounce of kernels.
That’s around 74% of the 2,300 mg Daily Value in a single ounce, because the salt coats the shells and ends up in your mouth with every seed. The fiber stays respectable, at about 2.6 grams per ounce of kernels.
If you love the in shell kind, look for lightly salted or unsalted versions, or switch to shelled kernels for everyday snacking and save the salty ones for the occasional game.
