Taste Test
I wanted to conduct original research on the topic and get the opinion of people like yourself. So I reached out to my clients, readers and members of food groups. I asked them, which one tastes better?
- 47% said they preferred the taste of hemp seeds
- 49% said they preferred the taste of flax seeds.
- 4% said it didn’t matter.
To conduct more research I setup and participated in a taste test at home. I used both in a smoothie without many other ingredients. This way I couldn’t tell the typical difference due to their shape and textures. I chose the smoothie with the flax seeds.
In the battle of taste, hemp seeds vs flax seeds, flax seeds was the winner in the poll and in my taste test.
Texture Comparison
Hemp seeds are soft and tender with a slight crunch. They have a smaller size and shelled seeds (hearts) feel creamy when chewed, making them pleasant as a topping or mix-in for various dishes.
Flax seeds, on the other hand, are harder with a glossy shell. Whole flax seeds often pass through the body undigested and add a crunchy element. Ground flaxseed feels more powdery or mealy and is commonly used to thicken or add bulk to foods.
Textural comparison:
- Hemp Seeds: Soft, tender, slight crunch (especially when raw or toasted)
- Flax Seeds: Hard, smooth outer shell (whole); powdery and dense (ground)
The choice between the two often depends on whether a creamy, soft texture or extra crunch and bulk is preferred.

Culinary Uses
Hemp seeds and flax seeds both offer unique textures and flavors for food preparation. Each seed type has distinct features that affect how they are best incorporated into meals.
Selecting the Right Seed for Your Needs
Hemp seeds, sometimes called hemp hearts, have a mild, nutty flavor and a soft texture. They are eaten raw and sprinkle easily onto foods without further processing. Flax seeds are smaller, with a harder outer shell and a more pronounced earthy taste.
Whole flax seeds are difficult to digest. To maximize nutritional benefits, they should be ground before use or purchased pre-ground. Hemp seeds can be eaten as they are and do not require grinding.
For those seeking higher protein, hemp seeds contain almost double the protein of flax seeds per serving. Flax seeds are often chosen for their higher fiber content and lignans, making them popular in recipes targeting digestive health.
Recipe Versatility
Both types of seeds work well in smoothies, yogurt bowls, salads, and oatmeal. Hemp seeds can also be mixed into energy bars or sprinkled on toast and roasted vegetables due to their soft texture.
Flax seeds are frequently used in baking. Ground flax can be added to muffins, pancakes, or bread, and it serves as an egg substitute in vegan recipes when mixed with water. Hemp seeds, with their mild taste, blend smoothly in dips, pesto, or dressings.
Both oils from these seeds can be used in salad dressings, though they are not suitable for high-heat cooking due to low smoke points. The versatility of these seeds makes them a practical addition to both sweet and savory dishes.
Nutritional Profile Comparison
Hemp seeds and flax seeds differ in their major nutrients and micronutrients, which can influence dietary choices depending on health goals. Both offer plant-based protein, healthy fats, and fiber, but with notable contrasts in each area.
Macronutrient Content
Hemp seeds are higher in protein, containing about 31-32 grams per 100 grams, compared to flax seeds at roughly 18 grams per 100 grams.
This makes hemp seeds a strong choice for those seeking more plant-based protein. Flax seeds excel in dietary fiber, offering about 27 grams per 100 grams, while hemp seeds provide only about 4 grams.
Flax seeds are especially useful for improving digestive health because of their high fiber content.
Both seeds offer healthy fats, but the fat content distribution differs: hemp seeds provide more omega-6 fatty acids, while flax seeds give more omega-3s (ALA).
Comparison Table: Macronutrients (per 100 grams)
| Nutrient | Hemp Seeds | Flax Seeds |
|---|---|---|
| Protein | 31-32 g | ~18 g |
| Fiber | 4 g | 27 g |
| Total Fat | 49-51 g | 42-44 g |
Vitamins and Minerals
Both seeds are rich in essential micronutrients. Hemp seeds are a stronger source of magnesium, phosphorus, iron, zinc, and manganese. Magnesium supports muscle and nerve function, while iron is important for oxygen transport in the blood.
Flax seeds provide high levels of thiamine (vitamin B1), copper, and selenium. Thiamine aids energy metabolism, while copper supports immune function and selenium acts as an antioxidant.
Flax seeds also contain lignans—phytonutrients with antioxidant properties—not found in significant amounts in hemp seeds.
In terms of daily mineral needs, hemp seeds can deliver a significant portion, especially for magnesium and zinc, making them useful for those with higher requirements in those nutrients.
Caloric Value
Hemp seeds and flax seeds are both energy-dense foods. Per 100 grams, hemp seeds provide roughly 550-575 calories, mostly from fats and protein. Flax seeds contain a similar caloric value, usually around 534-550 calories per 100 grams.
Because fiber content is much higher in flax seeds, some of its calories are not fully absorbed, lowering the effective energy available. Both seeds fit within high-calorie diets, particularly for those increasing protein or healthy fat intake.
Their calorie content makes portion control important if the goal is weight management. Flax seed’s higher fiber may support satiety more effectively than hemp seeds.
Protein Content and Quality
Hemp seeds and flax seeds both contain plant-based protein but differ in the amount, amino acid spectrum, and how easily the body can use the protein.
The distinctions between these seeds matter for anyone considering them as part of a balanced diet, especially those relying on plants for protein.
Amino Acid Composition
Hemp seeds provide about 10 grams of protein per 30-gram serving. They contain all nine essential amino acids, classifying them as a complete protein. However, some amino acids, like lysine, are present in moderate rather than high quantities.
Flax seeds offer about 6 grams of protein per 30-gram serving. While they have a broad amino acid profile, they lack sufficient amounts of lysine, making their protein incomplete for meeting all essential amino acid needs through flax alone.
Here’s a comparative look:
| Seed Type | Protein (per 30g) | Complete Protein | Notable Amino Acid Limitation |
|---|---|---|---|
| Hemp Seed | 10g | Yes | Moderate in lysine |
| Flax Seed | 6g | No | Low in lysine |
Those seeking a fully balanced amino acid intake may find hemp seeds more reliable. Flax seeds still contribute valuable protein, but not in a complete form.
Digestibility
The protein in hemp seeds is highly digestible, with estimates suggesting 90–98% of the protein is usable by the body. This is due to the presence of the globulin edestin and albumin, proteins that break down easily and are similar to those found in eggs and soy.
Flax seed proteins are less digestible, in part because their proteins are bound within fibrous seed coats. Grinding flax seeds can improve the availability, but the fibrous shell still limits how much protein can be effectively absorbed.
For individuals prioritizing protein utilization, hemp seeds have a clear advantage in digestibility over flax seeds. That makes them valuable for vegans, athletes, and anyone looking to maximize their plant protein intake.
Omega-3 and Omega-6 Fatty Acids
Hemp seeds and flax seeds both provide important essential fatty acids, but their nutritional profiles and health impacts differ in key ways. Understanding these differences can help people choose the best option for their needs.
ALA Content
Alpha-linolenic acid (ALA) is the primary plant-based omega-3 fatty acid in both hemp and flax seeds.
Flax seeds contain the highest ALA concentration among common seeds, offering about 6.5 grams of ALA per 28-gram (1-ounce) serving. Hemp seeds provide less, with roughly 2.5 grams of ALA per the same amount.
This significant difference makes flax seeds a more concentrated source of plant-based omega-3s. Both seeds contain only ALA—not EPA or DHA, the longer-chain omega-3s found in fish—but ALA can help meet daily requirements for many people, especially those on plant-based diets.
Anyone seeking to increase ALA in their diet will usually get more from flax seeds compared to hemp seeds.
| Seed Type | ALA per 28g (1 oz) |
|---|---|
| Flax Seed | ~6.5g |
| Hemp Seed | ~2.5g |
Balance of Essential Fats
The ratio of omega-6 to omega-3 fatty acids is important for maintaining healthy inflammation levels.
Hemp seeds have an omega-6 to omega-3 ratio of about 3:1, which many nutritionists view as desirable for health. Flax seeds, in contrast, have a much lower ratio, closer to 1:4, heavily favoring omega-3.
A lower omega-6 to omega-3 ratio is often considered better, but very low ratios might not reflect a typical balanced diet. Hemp seeds offer a more moderate ratio, while flax seeds tilt strongly toward omega-3 due to their high ALA content and low omega-6 level.
People interested in overall fat balance might choose hemp for its near-ideal ratio, while those focused mainly on maximizing omega-3 intake may prefer flax. Both options provide a healthier fat profile than many typical nuts and seeds.
Fiber Content
Hemp seeds and flax seeds differ in both the amount and types of fiber they provide. Understanding these differences helps clarify their effects on digestion and fullness.
Soluble vs Insoluble Fiber
Flax seeds are higher in total fiber compared to hemp seeds, especially when the flax seeds are consumed whole. They are particularly rich in soluble fiber, which absorbs water and forms a gel-like substance in the gut. This can help slow down digestion and support steady blood sugar levels.
Hemp seeds have less fiber overall, especially when hulled (hemp hearts). Their fiber content is mostly insoluble. Insoluble fiber adds bulk to stool, which may help prevent constipation but does not gel or slow digestion in the same way as soluble fiber.
A comparison of fiber content per 100 grams:
| Seed Type | Total Fiber | Soluble Fiber | Insoluble Fiber |
|---|---|---|---|
| Flax Seeds | ~27g | High | Moderate |
| Hemp Seeds | ~4g (hulled) | Low | Moderate |
Therefore, anyone seeking to boost soluble fiber intake may prefer flax seeds, while those who need only a moderate amount of fiber can consider hemp seeds.
Benefits for Digestion
The type of fiber in these seeds affects digestive health in different ways. Flax seeds, with their high soluble fiber content, can help regulate bowel movements and promote softer stools. This is especially useful for people dealing with irregularity.
Soluble fiber from flax seeds also acts as a prebiotic, feeding healthy gut bacteria. This interaction supports digestive balance and may contribute to a healthier gut environment.
Hemp seeds, with mostly insoluble fiber, help add bulk to waste and support regular elimination. While their fiber content is lower, they remain useful for people with sensitive systems or those who prefer a lighter fiber boost in their diet.
Selecting between these seeds often depends on individual digestive needs and tolerance to high-fiber foods.
Antioxidants and Phytochemicals
Hemp seeds and flax seeds both offer natural sources of antioxidants and phytochemicals. The composition and concentration of these protective compounds vary, affecting their potential health roles.
Lignans in Flax Seeds
Flax seeds are among the top dietary sources of lignans, a class of polyphenols found mostly in plant-based foods. Lignans have antioxidant properties and can influence hormone balance, particularly by exerting weak estrogen-like effects in the body.
Research shows that flax seeds contain up to 800 times more lignans than most other plant foods. These compounds are linked to potential benefits such as improved heart health and reduced risk of certain cancers, especially hormone-related cancers.
Flax seeds also provide the antioxidant profile in a ground form, making their lignans easier to absorb compared to some other seeds. Including flax seeds in the diet increases the intake of both fiber and antioxidants, as lignans are found in the fibrous outer shell.
Plant Compounds in Hemp Seeds
Hemp seeds have a different phytochemical profile, containing moderate amounts of antioxidants primarily in the form of tocopherols (a type of vitamin E) and various phenolic compounds. These contribute to the seeds’ ability to combat oxidative stress.
Compared to flax seeds, hemp seeds contain lower levels of lignans but compensate with a broader range of other plant compounds. Notably, hemp seeds offer gamma-tocopherol, a vitamin E variant linked to protecting lipids and cell membranes.
Additionally, hemp seeds supply small amounts of phytosterols, which may help support healthy cholesterol levels. While the antioxidant content is not as concentrated as flax, hemp seeds provide a wider spectrum of bioactive nutrients that contribute to overall wellness.
Cost and Availability
Flax seeds are widely available in grocery stores, health food shops, and bulk bins. Most supermarkets carry them in several forms including whole, ground (meal), and oil.
Hemp seeds, or hemp hearts, have become increasingly easy to find. They were once considered specialty items but now appear in major supermarkets and health stores alongside flax seeds.
Price differences are notable. According to recent sources, flax seeds are generally less expensive, with prices typically ranging between $2–$6 per pound. Hemp seeds cost more, usually about $12–$17 per pound for organic varieties.
| Seed Type | Typical Price per Pound (USD) | Availability |
|---|---|---|
| Flax Seeds | $2–$6 | Widely available |
| Hemp Seeds | $12–$17 | Increasingly common |
Both seeds are sold in bulk and packaged forms. Flax seeds may also be found in more product variations like oil and pre-ground meal, while hemp seeds are often sold as raw, shelled hearts.
Organic certification and specialty brands can influence cost. Flax seeds tend to remain the more budget-friendly choice, while hemp seeds are more likely to carry a higher premium, especially when sold as organic or non-GMO.
Some online retailers offer discounts for bulk purchases on both seed types. Availability can vary by region, but both seeds have become broadly accessible in most urban and suburban markets.
Allergen Risk and Safety Considerations
Food allergies to seeds are increasing, but the allergen risk from hemp seeds and flax seeds differs.
Hemp seeds are not among the most common seed allergens. However, rare cases of hemp seed allergy have been observed. Symptoms can range from mild irritation to more severe reactions in individuals with seed allergies or cannabis sensitivities.
Flax seeds can cause allergic reactions in some people. Flaxseed allergy is uncommon but reported in medical literature. Those with known flaxseed allergy should avoid all flax-containing foods and products.
| Seed Type | Common Allergen? | Reported Allergy Symptoms |
|---|---|---|
| Hemp Seeds | Rare | Irritation, anaphylaxis (rare) |
| Flax Seeds | Uncommon | Hives, swelling, anaphylaxis |
People with existing allergies to other seeds (such as sesame, sunflower, or poppy) may be at higher risk for developing allergies to either hemp or flax seeds. Cross-reactivity between seeds is possible.
Precaution is advised when introducing these seeds to the diet, especially for those with a history of allergies. Always check for hidden seed ingredients in processed foods.
Children, people with multiple food allergies, and those with immune sensitivities should consult a healthcare professional before adding hemp or flax seeds to their meals. Label reading is essential, as packaged foods may contain trace amounts of these seeds.
If any symptoms of an allergic reaction develop after consuming these seeds, seek medical attention immediately.
