Understanding Omega-3, Omega-6 and Omega-9, and Where Hemp Seeds Fit
The omega numbers appear everywhere, but they do not all mean the same thing. Here is a practical guide to the differences, why balance matters, and why hemp seeds deserve a place in the everyday conversation about healthy fats.
Hemp seeds bring essential plant fats, protein and a mild nutty flavour to everyday meals.
For years, fat was treated as the part of food we were supposed to avoid. Then came the opposite message: eat more healthy fats. Somewhere between the two, omega-3, omega-6 and omega-9 became familiar names without becoming especially well understood.
At Margaret River Hemp Co, we work with hemp seed every day, and one of the questions we hear most often is what those different omega numbers actually mean. Are they all good? Is omega-6 something to avoid? Does plant-based omega-3 count? And why do hemp seeds contain more than one kind?
The answer is that each omega family has a different role. Some must come from food, some can be made by the body, and no single food needs to do every job. Hemp seeds stand out because they bring several useful unsaturated fats together in one simple whole food, alongside plant protein, minerals and a mild, nutty flavour.
Omega fatty acids are types of unsaturated fat. The number tells us where the first double bond sits in the fatty acid chain. That sounds technical, but the practical point is simple: omega-3, omega-6 and omega-9 are related, but they are not interchangeable.
Health authorities including the World Health Organization encourage replacing more saturated fats with unsaturated fats. The omega families are part of that broader picture, but each deserves to be understood on its own.
Omega-3 and omega-6 are essential. Omega-9 is not essential, although it remains a useful unsaturated fat.
| Family | Essential? | Main forms | Where hemp fits |
|---|---|---|---|
| Omega-3 | Yes | ALA from plants; EPA and DHA mainly from seafood and algae | Hemp seeds provide the plant omega-3 ALA. |
| Omega-6 | Yes | Linoleic acid is the main dietary form | Hemp seeds naturally contain linoleic acid. |
| Omega-9 | No | Oleic acid is the best-known form | Hemp seeds and hemp seed oil also contain oleic acid. |
Table 1. A simple comparison of omega-3, omega-6 and omega-9.
Omega-3 is the best-known member of the family, but the name covers several different fatty acids. The three most commonly discussed are ALA, EPA and DHA.
ALA, or alpha-linolenic acid, is the main plant-based omega-3. It is essential, which means our bodies cannot make it and we need to obtain it from food. Hemp seeds, flaxseed, chia seeds, walnuts and canola oil are all sources of ALA.
EPA and DHA are longer-chain omega-3s found mainly in seafood and algae. The body can convert some ALA into EPA and DHA, but the conversion is limited. That is why hemp seeds should be celebrated for what they genuinely provide: plant-based ALA, rather than presented as a direct replacement for fish or algal sources of EPA and DHA.
The National Institutes of Health omega-3 fact sheet explains this distinction in more detail and notes that consuming EPA and DHA directly is the most practical way to raise those long-chain omega-3 levels.
Hemp supplies ALA. The body can convert some ALA to EPA and DHA, but the conversion is limited.
Omega-6 has developed an unfair reputation. The main dietary omega-6, linoleic acid, is also essential. We need it from food, and it contributes to normal growth, cell structure and everyday body function.
The confusion comes from modern diets that can be very high in refined oils and heavily processed foods. This has led to an oversimplified idea that omega-6 itself is bad. It is more useful to look at the whole dietary pattern: where the fats are coming from, whether the diet contains enough omega-3, and whether whole foods are replacing highly processed choices.
Hemp seeds naturally contain both omega-6 linoleic acid and omega-3 ALA. That does not mean they deliver a mathematically perfect diet in one spoonful. It does mean they provide both essential fatty-acid families together in a whole-food form.
Omega-9 fats are usually monounsaturated fats. Oleic acid, the best-known omega-9, is abundant in olive oil and is also present in hemp seeds and hemp seed oil.
Unlike omega-3 ALA and omega-6 linoleic acid, omega-9 is not classed as essential because the body can make it. That does not make it unimportant. Foods rich in unsaturated fats can still be useful choices when they replace foods high in saturated fat.
Hemp seeds are especially interesting because their natural oil contains omega-3, omega-6 and omega-9. Their main omega-3 is ALA, their main omega-6 is linoleic acid, and they also contain oleic acid from the omega-9 family.
Hemp seeds are often described as having an omega-6 to omega-3 ratio of around 3:1, although the exact figure varies with the variety, growing conditions and processing. We do not think anyone needs to obsess over a single ratio. The more useful message is that hemp offers meaningful plant omega-3 alongside its omega-6, rather than being overwhelmingly weighted toward omega-6 like many common refined oils.
| Hemp’s strength is not that it replaces every other omega source. It is that it makes essential plant fats remarkably easy to add to ordinary food. |
Hemp seed foods offer more than fatty acids alone, with plant protein and minerals in versatile pantry formats.
| Food | Main omega contribution | What it does well | Keep in mind |
|---|---|---|---|
| Hemp seeds | ALA, linoleic acid and oleic acid | Soft, nutty, no grinding required; also supplies plant protein and minerals | Provides ALA rather than direct EPA or DHA |
| Flaxseed | Very rich in ALA | Strong plant omega-3 contribution | Whole seeds are best ground for practical use |
| Chia seeds | Rich in ALA | Easy in puddings, oats and baking; also adds fibre | Texture changes as it absorbs liquid |
| Oily fish | EPA and DHA | Provides long-chain omega-3 directly | Not suitable for everyone; quality and sustainability choices matter |
| Algae oil | DHA and sometimes EPA | Direct marine-type omega-3 without fish | Usually used as a supplement rather than a whole food |
| Olive oil | Mostly omega-9 oleic acid | Versatile monounsaturated fat | Not a meaningful source of omega-3 |
Table 2. Different foods contribute different omega fatty acids. They can complement rather than compete with one another.
Flax and chia are excellent plant sources of ALA and generally contain more ALA per 100 grams than hemp. They are valuable foods, and there is no need to turn the omega conversation into a competition.
Hemp has a different set of practical strengths. Hulled hemp seeds are soft rather than hard, do not need grinding, have a gentle nutty flavour, and work just as naturally in savoury dishes as they do in breakfast bowls and baking. They also provide plant protein and useful minerals as part of the same whole food.
Fish and algal oils play another role because they provide EPA and DHA directly. For people who eat seafood, oily fish can sit alongside hemp seeds in a varied diet. For people who avoid fish and want direct DHA or EPA, an algae-based source may be worth discussing with a qualified health professional. Hemp seeds contribute ALA; they do not need to pretend to be something else to be worthwhile.
You may have seen claims that everyone should aim for one precise omega-6 to omega-3 ratio. Nutrition is rarely that tidy. The total diet matters more than chasing a single number, and individual needs vary.
Australian Nutrient Reference Values provide separate adequate-intake guidance for ALA and linoleic acid, reinforcing that both are required. A sensible everyday approach is to include varied sources of unsaturated fat, eat fewer highly processed foods, and regularly include foods that supply omega-3.
That is one reason we like hemp seeds so much. They are not a capsule, a trend or a complicated dietary rule. They are food. You can see them, taste them and use them in meals you already enjoy.
Both have a place, but they are not identical.
Our Australian grown hulled hemp seeds provide the seed’s natural fats together with protein, fibre and minerals. They are ideal for sprinkling over oats, yoghurt, salads, soups, pasta, toast and roasted vegetables, or blending into smoothies and sauces.
Our cold-pressed Australian hemp seed oil concentrates the oil fraction and works beautifully in dressings, dips, smoothies and finished dishes. Because its delicate polyunsaturated fats are sensitive to high heat, we prefer it used cold or added after cooking rather than treated as a high-temperature frying oil.
Hemp seeds work in savoury and sweet meals, from avocado toast to porridge and smoothie bowls.
The omega conversation can become needlessly complicated. The simplest summary is this: omega-3 and omega-6 are essential, omega-9 is not essential but is still a useful unsaturated fat, and different foods provide different forms.
Hemp seeds do not provide meaningful EPA or DHA, and we would never suggest otherwise. What they do provide is a naturally balanced mix of unsaturated fats, including the essential plant omega-3 ALA, in a versatile whole food that is easy to use every day.
Low-THC hemp seed foods have been permitted in Australia since 2017, and Food Standards Australia New Zealand recognises hemp seeds as a food containing protein, vitamins, minerals and polyunsaturated fatty acids, particularly omega-3 fatty acids.
For us, that is the real positive case for hemp: no miracle claims, no nutritional one-upmanship and no need to overhaul your diet. Just a useful Australian-grown seed with healthy fats, plant protein, a lovely nutty flavour and dozens of ways to fit into real meals.
