Are Flaxseed and Linseed the same thing?

Flaxseed vs Linseed: Are They the Same Thing?

Flaxseed and Linseed come from the same plant. The two names are often used interchangeably – but do they really mean the same thing? If you’ve ever been confused by the words flaxseed and linseed, you’re not alone. The terminology used mostly comes down to the intended use for the seed, the country and the type of industry.

Let’s dig into the history, science, and everyday use of this tiny but mighty seed.

A Plant with Many Names

Flaxseed and linseed are both harvested from the same plant - Linum usitatissimum - which translates from Latin as “very useful.” It’s no surprise – for thousands of years flax has been valued for its food, medicine, and fibre.

• Flaxseed is the common English name, often used when talking about the seed sold for food purposes. This name became popular as it sounds appealing and is closely related to health and wellness products. The term ‘flax’ is just an abbreviation of flaxseed. Some historians note that early New Zealand settlers popularised the word flax in reference to the plant’s strong fibres for weaving – a reminder of its long history in textiles as well as nutrition.

• Linseed comes from the plant’s genus name, Linum, and is widely used in Europe and other parts of the world. Traditionally this name has been used in farming and industrial purposes. Linseed oil for example has long been used in paint, wood finishes, and other products. Farmers tend to refer to crops grown for seed production as linseed crops.

In practice, both words describe the same thing – but ‘flaxseed' is the term most commonly used when talking about health and nutrition. Flaxseed is also the terminology Waltanna Foods mostly uses when talking about their products (shop flaxseed here).

Different Varieties

Not all flax plants are grown for the same purpose. Over time, farmers have bred flax into different varieties, depending on the end use:

• Fiber flax – tall plants grown mainly for their stems, which are processed into linen fabric.

• Oilseed flax (linseed) – bred for higher oil content, often used for linseed oil in food or industry.

• Table seed flax – grown for human consumption as whole or ground seeds.

Flaxseed also comes in two main colours: brown and golden (yellow). Golden flaxseed typically is lighter in colour and brown flaxseed is a darker seed which is more readily available. Both are highly nutritious, with only slight differences in taste. Golden flaxseed can have a slight milder flavour profile. The choice between them generally comes down to personal preference, appearance, or specific recipe requirements.

Nutritional Value

Whether labelled flaxseed or linseed, gold or brown, the nutritional profile is essentially the same. Flaxseed is widely valued for its impressive nutrient content including dietary fibre, protein, lignans, and the standout feature is its high concentration of plant based Omega-3 fatty acid (alpha-linolenic acid [ALA]). ALA is an essential fat, meaning the body cannot produce and it must be obtained from food. So, add these amazing little seeds into your diet!

Flaxseed is also a great source of dietary fibre, containing both soluble and insoluble fibre. These fibres support digestive health and can promote feelings of fullness.

Another unique characteristic of flax/linseed is its high lignan content. Lignans are naturally occurring plant compounds with antioxidant properties. In fact, flaxseed contains significantly more lignans than most other commonly consumed plant foods.

Flaxseed Oil and Linseed Oil

When discussing the oil that can be expelled from the crop, the terminology can become particularly important.

Cold-pressed flaxseed oil produced for human consumption is manufactured under strict food-grade standards and is intended for dietary use. It is valued for its high omega-3 content and mild flavour. High quality flax oil with have  smooth, slightly nutty flavour with little to no after taste.

Industrial linseed oil, while originating from the same seed, may be processed differently and is intended for non-food applications such as timber finishes, paints, and coatings. You would likely not enjoy the taste or flavour if sampling this kind of oil, as it has not been strictly filtered in the same manner that flaxseed oil intended for human consumption has been. It would taste very bitter and rancid in flavour.

Consumers should always ensure they are purchasing food-grade flaxseed oil if the product is intended for consumption.

Why It Matters

Whether you call it flaxseed or linseed, you’re talking about one of the most versatile plants in the world. Packed with omega-3 fatty acids, fibre, and plant lignans, flax has benefits for heart health, digestion, and overall wellbeing.

So next time you see both words on a package or recipe, you’ll know: flaxseed and linseed are one and the same. The only difference is in how people use the name.

 Summary and take away:

Flaxseed = food and nutrition.

Linseed = oil or industrial uses.

Same seed, different context.
