Seeds may not be among the most exciting foods, but they offer a lot of nutritional value.
Like nuts, edible seeds provide an excellent dose of healthy fats and essential nutrients.
Most seeds are a rich source of minerals, and they are generally quite affordable too.
In this article, we look at twelve different types of seeds and summarize their main nutritional benefits.
Unless otherwise stated, the source of all nutritional data is the USDA’s FoodData Central database.
Table of contents
1) Chia Seeds
Chia seeds are tiny black, grey, or white seeds that have been popular in Central America since ancient times, and they were a staple of the Aztec diet (1).
These seeds have become increasingly popular over the past decade, and they are a rich source of omega-3 in alpha-linolenic acid (ALA) form.
ALA needs converting to the more bioavailable DHA and EPA (as found in seafood) before the body can use it. On this note, the conversion rate tends to be lower than 15% (2).
While this conversion rate may sound low, chia can still contribute a beneficial amount of omega-3 to the average diet.
The table below shows the basic nutritional values for one ounce (28.5 grams) of chia seeds (3):
|Saturated Fat||0.94 g|
|Monounsaturated Fat||0.65 g|
|Polyunsaturated Fat||6.71 g|
Chia seeds have a high concentration of soluble fiber, and they are capable of absorbing significant amounts of water (4).
For this reason, the seeds create a gel-like consistency when added to water/drinks.
In terms of flavor, chia tastes kind of nutty, and the seeds are crunchy when raw and soft after absorbing water.
Regarding their essential nutrient profile, one ounce of chia seeds provides an excellent source of (3):
- Vitamin K1: 167% of the daily value (DV)
- Manganese: 33% DV
- Magnesium: 26% DV
- Iron: 26% DV
- Phosphorus: 20% DV
2) Egusi Seeds
Egusi seeds are one of the lesser-known seeds in the Western world. The seeds come from a sour-tasting, watermelon-like fruit, which is incredibly bitter (and also known as ‘sour apple’) (6).
Additionally, these seeds tend to be ground into powder and then used as an ingredient in cooking due to their thickening properties and flavorful taste.
One popular recipe is egusi soup, a regional West African dish featuring meat and various vegetables (7).
Unfortunately, the full nutritional values of egusi seeds are not currently available in a reputable nutritional database.
However, research demonstrates that they are a good source of monounsaturated fat, B vitamins, and minerals (8).
3) Flax Seeds
Flax seeds are one of the most popular edible seed varieties, and they come in several different forms:
- Whole flax seeds
- Ground flax powder
- Flax oil
Flax seeds are also sometimes known as linseeds, and they come in two main varieties: brown and yellow.
One ounce (28.5 grams) of flax seeds provides the following nutrition profile (9):
|Saturated Fat||1.04 g|
|Monounsaturated Fat||2.13 g|
|Polyunsaturated Fat||8.14 g|
Flax seeds offer a reasonable range of essential nutrients, and per ounce serving, they are high in (9):
- Thiamin (B1): 39% DV
- Copper: 39% DV
- Manganese: 30% DV
- Magnesium: 26% DV
- Phosphorus: 15% DV
4) Hemp Seeds
Hemp seeds are nutrient-rich, containing high levels of numerous vitamins and minerals.
Some people enjoy the seeds raw, and hemp flour is a popular ingredient for baking purposes.
Nutritionally, hemp seeds have the following profile per ounce (28.5 gram) serving (10):
|Saturated Fat||1.30 g|
|Monounsaturated Fat||1.53 g|
|Polyunsaturated Fat||10.80 g|
As shown, hemp seeds are surprisingly high in protein and contain little carbohydrate.
The seeds are high in fat, and most of this is polyunsaturated fat—predominantly omega-6.
Here are some of the most concentrated vitamins and minerals an ounce serving offers (10):
- Manganese: 93% DV
- Copper: 50% DV
- Magnesium: 47% DV
- Phosphorus: 37% DV
- Thiamin (B1): 30% DV
5) Jackfruit Seeds
Jackfruit is officially the biggest fruit in the world (11).
Interestingly, the edible seeds of this giant fruit have become popular in recent years.
However, they are pretty different from other seeds in a nutritional sense. For example, jackfruit seeds are primarily a source of carbohydrates rather than fat.
Unfortunately, major nutrition databases do not supply the complete nutrient profile for jackfruit seeds.
That said, four separate studies have looked into the nutritional properties of jackfruit seeds. Based on the mid-point of the range of this nutritional data, here are the nutritional values for jackfruit seeds per ounce (28.5-gram) serving (12):
|Fat||0.12 g||Protein||1.93 g|
Jackfruit seeds also offer small amounts of riboflavin, thiamin, magnesium, and phosphorus.
In its South-East Asian homeland, people consume jackfruit seeds either raw or roasted (13).
According to some, they taste similar to chestnuts once roasted.
6) Lotus Seeds
The lotus flower is famous for its attractive pink appearance, and it produces unique round-shaped white seeds.
Lotus seeds are quite different from most types of seeds, and they are low in calories, fat, and carbohydrate.
Per ounce (28g) serving, here are their basic nutritional values (14):
|Saturated Fat||0.02 g|
|Monounsaturated Fat||0.03 g|
|Polyunsaturated Fat||0.09 g|
Lotus seeds are not particularly rich in essential nutrients, but per ounce serving, they contain small to moderate levels of (14):
- Manganese: 8% DV
- Phosphorus: 4% DV
- Magnesium: 4% DV
- Thiamin (B1): 4% DV
- Potassium: 2% DV
7) Nigella Seeds
Nigella seeds are edible seeds with an intense flavor.
However, people don’t eat them raw, and the seeds are typically an ingredient for seasoning various dishes.
For instance, nigella seeds frequently feature in regional Indian curries (15).
Nigella seeds have several different names, and they may also be called kalonji, fennel, and black cumin.
Nutritionally, nigella seeds provide the following profile per ounce (28g) (16):
|Saturated Fat||0.1 g|
|Monounsaturated Fat||2.8 g|
|Polyunsaturated Fat||0.5 g|
However, it is worth noting that the average serving size is much less than this, at around one teaspoon to one tablespoon.
Nigella seeds are a reasonably good source of nutrients, and per ounce, they provide (16):
- Manganese: 91% DV
- Calcium: 33% DV
- Iron: 29% DV
- Magnesium: 27% DV
- Copper: 15% DV
Interestingly, research findings from several randomized controlled trials suggest that nigella seeds may have a beneficial effect on lowering blood pressure (17).
8) Poppy Seeds
Poppy seeds are another edible seed with a nutty flavor.
Although it is possible to eat them raw, these seeds often feature as an ingredient in bakery products.
Poppy seeds are mainly a source of fat, but they are also relatively high in dietary fiber. Here are their basic nutritional values per ounce (28.5-gram) (18):
|Saturated Fat||1.28 g|
|Monounsaturated Fat||1.70 g|
|Polyunsaturated Fat||8.10 g|

- Manganese: 83% DV
- Copper: 51% DV
- Calcium: 31% DV
- Magnesium: 23% DV
- Phosphorus: 20% DV
It is also worth noting that these seeds come from the opium plant. Although it appears to be unlikely, research suggests that contamination during the harvesting of poppy seeds could potentially cause false-positive drug tests for opiates (19).
See this complete guide to poppy seeds for more information.
9) Pumpkin Seeds
These dark green seeds have a mild and nutty flavor, and they’re surprisingly high in protein.
Pumpkin seeds are also one of the best dietary sources of magnesium. Here are their basic nutritional values per ounce (28.5 gram) serving (20):
|Saturated Fat||2.45 g|
