Looks certainly be deceiving. This tiny little member of the seed family is actually a powerful superfood with enormous health benefits. As long as it’s ground-up before you eat it, flaxseed is incredibly easy to incorporate into your daily regimen.

I’ll show you some great tips for getting more of this beneficial food into your meals, and explain why everyone needs more flaxseed in their life.

What are flaxseeds?

Flax seeds, also known as linseeds, are the seeds of the flax plant. Every part of the flax plant has its use. Flax fibers are used to make linen and rope. Flax seeds are also used to make linseed oil, used in woodworking and carpentry.

As far back as 30,000 years ago, flax has been cultivated and grown as a steady crop in Egypt, Switzerland, Syria, and China. And as if that’s not enough, this wondrous little seed scores huge in the health department, too.

Taste profile

Like many seeds, flaxseeds have a slightly mild, nutty flavor so they’re ideal for adding to both sweet and savory foods. In case you’re wondering, children and picky eaters may not notice a little flaxseed meal when it’s added to their favorite foods in small amounts.

How it’s grown

Only the sturdiest and most tenacious plant could last thousands of years. Linum usitatissimum, Latin for “the most useful kind of flax,” is the variety of flax that’s cultivated for seeds. It grows in huge fields and it likes full-sun, cooler climates with well-drained soil.

When the seed pods swell and turn brown after blooming, the seeds are harvested. Canada supplies the majority of the brown flax seeds, while North America grows the golden variety.

Types of flaxseeds

There are two basic types of flax seeds, brown and golden, both found in health food and specialty stores. Most people find that the dark brown seeds have a somewhat stronger flavor than the golden seeds. Both are good sources of alpha-linolenic acid, although the dark seeds are slightly higher in ALA than the golden variety.

What is flaxseed oil?

For a more concentrated dose of all the benefits flaxseed has to offer, many people rely on flaxseed oil, which is extracted oil from the seed. Since it’s an oil, it’s richer than ground flaxseed, but it’s a wonderful supplement on its own.

One teaspoon of flaxseed oil contains 40 calories. Not only can flaxseed oil be consumed, but it can be used directly on the skin to balance out minor skin problems, as well.

How to use flaxseeds

Since whole flax seeds aren’t able to be fully digested by the body, they have to be ground up before you eat them. The best way to do this is in a small coffee grinder, spice mill, or even a mortar and pestle. Grind just what you need, though, because ground meal spoils quickly.

Buying and storing flaxseeds

Because flaxseed, flaxseed meal, and flaxseed oil are all light-sensitive and can degrade with prolonged exposure to light, make sure you look for opaque packaging in the products you buy and read the recommended “use by” dates on the labels carefully.

Thankfully, whole flax seeds can keep at room temperature for up to a year, but once they’re ground, the flaxseed meal should be used as soon as possible. Flaxseed oil can also go rancid if not used efficiently. Try to purchase smaller amounts of oil and pre-ground meal, and use what you grind in a short amount of time.

How to cook with it

  • Thickener in recipes: Using flax is a great way to naturally replace gluten-containing grains in recipes, especially baked ones; flax is usually easily metabolized.
  • Egg substitute: That’s right! You can replace eggs in a recipe using finely ground flax seed. Use one tablespoon of flax seeds and three tablespoons of water, combined, to replace one egg. The seeds have a gelatinous quality that emulsifies much the way an egg would.

Recipes ideas

  • Smoothies: For a morning jumpstart, add a tablespoon or two of ground flaxseed meal into a smoothie or shake. Your day just got a little healthier!
  • Baking: Ideal for cookies, muffins, pancakes, and quick breads: If you love to bake, coarsely ground flaxseeds can be added to any of these to boost texture and nutrition.
  • Salads: Drizzle some flaxseed oil over roasted vegetables, or add the chopped seeds as a last-minute topping. If you like, switch out olive oil and make a vinaigrette out of flaxseed oil.
  • Snacks: Flaxseed oil can be sprinkled on popcorn or the ground meal can be mixed with herbs and spices and used to make your own crackers or baked chips.
  • Oatmeal: With flaxseed meal, oats just got a lot smarter. Shake overcooked oatmeal or pudding made of soaked chia seeds with a little cinnamon and brown sugar.
  • Granola and breakfast bars: If you make your own energy bars or granola, add ground flax meal to the recipe.

Hint: because flaxseed oil has such a low smoking point, (225) avoid cooking with it. However, it does make a wonderful neutral oil for seasoning cast iron pans.


If you’re on a low carb, Whole30, or Paleo specific diet, incorporating the healthy fats that seeds offer into your diet is especially important. Flax seeds and flaxseed oil are highly recommended for their low carb properties and their high quantities of essential fatty acids, edging out even chia seeds, which have slightly lower levels of omega-3 fatty acids.

Furthermore, those following strict plant-based diets will benefit from flaxseed oil, as it favorably compares to fish oil in terms of omega-3s.

Nutritional profile per serving

Eating two tablespoons of ground flax seed a day will provide about 20 percent to 25 percent of your fiber needs. (Most adults should aim to consume between 25–40 grams of fiber a day.)

  • 3.6 g of plant-based omega-3s
  • 75 calories
  • 2.6 grams of protein
  • 4 grams of carbohydrates (mostly fiber)
  • 6 grams of fat

Health benefits of flaxseeds

  • Omega-3 essential fatty acids, known as the “good” fats that have been shown to have heart-healthy effects. Research indicates that flaxseed could reduce the risk of cardiovascular disease and certain types of cancer, like prostate cancer and breast cancer. Besides that, essential fatty acids keep skin, nails, and hair shiny and healthy.
  • Lignans, which have both plant estrogen and antioxidant qualities, promoting hormonal balance. Flaxseed is the highest source of lignans in the plant world; it contains 75 to 800 times more lignans than other plant foods. The lignans in flaxseeds may help both menopausal and postmenopausal women alike.
  • Fiber. Flaxseed contains both the soluble fiber and insoluble fiber, which can help with regulating blood sugar, promoting weight loss and preventing constipation. Soluble fiber can also help reduce LDL cholesterol levels.
  • Polyunsaturated fatty acids such as alpha-linolenic acid. The alpha-linolenic acid and related chemicals in flaxseed oil seem to have anti-inflammatory properties. That is why flaxseed oil is considered useful for rheumatoid arthritis and other inflammatory diseases.
  • Choline, which contributes to brain health and function.

    Thank you !

    I am using flax seeds for last 4 to 5 years in oatmeal and smoothies. I use little less often in the summer time since it is hot in characteristics.
    It is used as horse feed in winters in some countries.

    do you know what the gelatinous material is that is formed from soaked flaxseeds, and is it itself nutritious?

  5. Ahmed Hassanin says

    Hi Jessica
    I am wondering if there is any difference between golden and brown flaxseeds as I have noticed difference in price between both products?
    Thank you very much

  6. Naimairfan says

    I heard flax seeds eaten with a meal can prevent nutrients absorption. So you should wait 30 min before eating something after flax seeds. Is it true?

  7. Mary Uloma says

    I am surprised to hear that flaxseed can replace egg in some recipes. Please just like we can fry egg, can that be fried too

  8. James Prada says

    Hi girl. You know… I have a problem with grinding my flax seeds because I don’t have a grinder. Is it save and healthy to just boild this and to drink this liquid? Please can you anwser me on my mail. Thank you!

    • Jessica Gavin says

      I would just add whole flaxseeds as a topper on things like oatmeal and yogurt for a nutritional boost if you don’t have a grinder. I don’t see any reason why you couldn’t drink it after boiling, but I don’t think the texture will change much.

  9. Vienna B. Gustaman says

    Hello Ms Jessica. Can my 1 year and 3 mos old baby can eat flaxseeds?
    Thank you for your response. Have a great day ahead!

  10. Roy says

    I like to eat flax seeds whole- I chew
    Them throughly ( think I’m addicted to the the taste and the chewing process!) I usually eat no more than 3-4 tablespoons a day (1/2 teaspoon at the time)
    Do you see any problems with this?

    • Jessica Gavin says

      It’s best not to use flaxseed oil with high heat, as the flavor can get bitter. I would instead add it as a finishing oil at the end of cooking for it’s nutty flavor in soups or sauteed vegetables. Or use a small amount in addition to another oil for dressings.

  12. Jose says

    Hello Jessica,
    By the means of grinding, but can a Vitamix provide a similar result–powder or would that be too fine?

  13. Riya Agrawal says

    Very interesting read. Thanks for sharing this informative article. I use True Elements Flax Seeds which is healthy and is 100% natural. However, I read somewhere that flax seeds can be used to make cakes, is it true?
