Scientifically Proven Health Benefits of Flaxseeds

Flaxseeds and flaxseed meal are a rich source of fiber, omega-3 fatty acids, vitamins, and minerals. Flaxseed meal is a great addition to your diet because flaxseeds are low in calories, low in carbs, and are gluten-free. Eating raw ground flaxseeds can help to improve your heart health, lose weight, boost your digestive health, and improve your skin’s appearance.


Consuming flaxseed meal is also good if you have a gluten intolerance. Flaxseed isn’t a grain, and it contains more nutrients than many grains do without having any gluten. The high fiber content of flaxseed and its low carbohydrate value means that flaxseed meal is good for diabetics and others who need to consume low-starch foods.

In this article, you will learn about the many reasons why flaxseed meal is good for you. You will also find out how much flaxseed you need to eat to lose weight, maintain heart health, lower cholesterol, and improve cognitive function.

What Are Flaxseeds?

Flaxseeds are a functional food because of their high nutritional value. Flax or flax seeds (Latin, Linum usitatissimum) are also called linseeds.

Flaxseeds look like small flat seeds that can vary in color from golden yellow to dark brown. Raw flaxseeds have a distinct nutty taste.

The seeds of the flax plant contain an outer shell. These shells are edible but are difficult to digest. That is why when using flaxseeds in drinks or eating the seeds raw, you need to grind the flax seeds into a powder.

The Journal of Food and Science Technology reports that all parts of the flaxseed plant can be used. The stalks of the flax plant are used in industry for making strong fiber. However, in recent years, many people have become interested in the therapeutic use of flaxseeds for treating various health conditions. (1)

Flaxseed is a rich source of healthy fats, lignans (plant-based phytoestrogens with antioxidant properties), and dietary fiber. In fact, researchers say that flaxseed can contain up to 800 times more lignans than other grains, seeds, or legumes. (2)

What is Flaxseed Meal?

Flaxseed meal is seeds from the flax plant that have been ground up into a type of flaxseed flour. Consuming flaxseed meal allows you to get all the nutrients, minerals, and vitamins from seeds.

Flaxseed meal looks like a powder substance and will help to improve the nutritional value of your meals and drinks. In fact, because flaxseed meal has so much fiber, you will feel fuller for longer after having one or 2 spoons of flaxseed.

You can add a teaspoon or 2 of flaxseed meal to drink with a glass of water. Or, you can grind up flax seeds and sprinkle a tablespoon of flaxseed on your salad, soup or yogurt. You can also add milled flaxseed to your favorite smoothie.

Flaxseed vs. Flaxseed Meal

Consuming whole seeds from the flax plant will usually end up with them going straight through your digestive system. Although chewing flaxseeds will help to break them up and make them easier to digest, many will remain whole and intact.

When adding flax seed to your diet, it is best to grind flaxseed to create flaxseed flour or powder. This lets your body absorb all the nutrients that are packed into each seed.

For example, the Journal of the American College of Nutrition reports on the nutritional difference between whole flaxseed and flaxseed meal.

Ingesting milled flaxseed resulted in the body absorbing omega-3 fatty acids. However, consuming whole flaxseeds did not release any omega-3. In fact, consuming whole flax seeds resulted in gastrointestinal upset. (3)

Flaxseed meal is rich in healthy fats and fiber, so it’s great to use it when you are baking. This will also increase the fiber content of your food and add a nutty flavor.

When buying flaxseeds to use in your diet, you should always buy whole seeds. You should then grind them into powder when you want to use them. This way you retain all of the nutritional value of flax seeds.

Flaxseed Meal – Nutrition Facts

Consuming ground flaxseed as part of a healthy diet can give you plenty of nutrients that are good for your health.

The United States Department of Agriculture reports that 2 teaspoons of ground flaxseeds contain just 13 calories and 0.7 grams of carbohydrates. (4)

This relatively small serving of 4 grams of flaxseed meal (2 tsp.) contains 0.7 grams of fiber which is 3% of your recommended daily intake (RDI).

Researchers have also found that flaxseed meal is a rich source of polyunsaturated fatty acids (PUFAs). More than 70% of the oil in each flaxseed is alpha-linolenic (ALA) omega-3 fatty acid. 10 grams of milled flaxseed contains 2,338 mg of omega-3 fatty acids. (5)

Flaxseed also contains proteins and essential amino acids.

One of the many health benefits of flaxseeds is that they are rich in lignans. Studies have shown that flaxseeds are one of the richest foods for lignans. Lignan-rich foods help to improve the gut’s microflora and they also have an antioxidant and anticancer effect. (2, 6)

Another reason to eat ground flaxseeds is that they contain antioxidants. As well as lignans having antioxidant potential, there are other compounds in flaxseed that help destroy toxins in the body. (7)

Some studies show that humans can consume up to 50 g of flaxseeds per day without any adverse side effects. (5)

You can also improve the fiber content and antioxidant content of baked goods and snacks by incorporating flaxseed. The journal Food Research International reported that heat doesn’t destroy the antioxidant capability of flaxseeds. (8)

How to Grind Flaxseeds to Make Flaxseed Meal

The easiest way to make your own flaxseed meal is to put a couple of tablespoons in a coffee grinder and mill the seeds. You can then add a few teaspoons of flaxseed powder to your favorite smoothie.

It is good to remember that the nutritional value of ground flaxseed can quickly be lost. So, put any leftover flaxseed meal in your freezer for later use.

What Are Flaxseeds Good For? Scientifically Proven Benefits of Flaxseed Meal

Let’s look in more detail at what scientific studies have revealed as to the many reasons why flaxseeds are so good for you.

Flaxseed Meal Is Good for Weight Loss

Ground flaxseeds can help you lose body fat because it is highly nutritious and contains a lot of fiber.

Flaxseed Meal Promotes Good Heart Health

Because ground flaxseed contains omega-3 and is high in antioxidants, flaxseed consumption helps protect your cardiac health.

There are a number of factors which combine in flaxseed to make it so good for your heart health.

Flaxseed meal lignans have been shown to exert a positive effect on cardiovascular health. For example, flax lignans help to prevent a buildup of plaque in the arteries. (15)

Other studies point to the fact that flaxseeds are one of the best plant sources of ALA omega-3 fatty acids. Long-term ALA intake can have a positive effect in preventing cardiovascular disease. (16)

One randomized trial found that consuming 60 g of flaxseed meal per day helped to reduce vascular-related inflammation and help prevent blood clots. (17)

Learn about other foods and herbs you can add to your diet that promote good cardiovascular health.

Flaxseed Meal Helps Lower Blood Pressure

If you suffer from hypertension, then consuming milled flaxseed every day can help to reduce high blood pressure.

A review of 11 studies on the effects of flaxseed powder on blood pressure found positive results. The high fiber, lignan, and omega-3 content of ground flaxseed helped to lower blood pressure. (18)

Flaxseed Meal Can Help if You Have PCOS

Taking ground flaxseed every day can be good if you suffer from polycystic ovarian syndrome (PCOS).

PCOS is a hormonal disorder that affects many women. This disorder causes irregular periods, excessive facial hair growth, and weight gain.

Researchers have found that flaxseed can reduce levels of testosterone and lower androgen levels. High levels of these hormones in women are often connected to PCOS.

In a case study one woman took 30 g of flaxseed supplements daily for a 4-month period. The woman reported a decrease in her symptoms of PCOS. Scientists also noted a decrease in androgen levels. (23)

Flaxseed Is Good for Hair Growth

Milled flaxseed contains many of the nutrients and fatty acids that are needed to help keep hair and scalp healthy.

Although there is no direct scientific research that flaxseed oil and flaxseed meal could help hair growth on humans, studies on animal subjects have shown positive results.

Results from a study in 2013 showed that daily consumption of flaxseed oil promoted hair growth in rabbits. (27)

Another study reported that flaxseed was good for hair growth. Scientists found that over a 3-month period, daily consumption of flaxseed meal boosted hair growth and increased hair length on rabbits. (28)

Find out about some interesting clinical trials involving humans showing which natural ingredients can make hair grow faster.

Flaxseed Meal Promotes Healthy Digestion

One of the health benefits you will feel when consuming ground flaxseeds every day is that your digestive health should improve.

Flaxseed is a good source of dietary fiber because about 40% of the flax seed is either soluble fiber or insoluble fiber. (2)

Researchers say that fiber is essential for good digestion. Fiber absorbs water and helps to bulk-up stool, making it easier to pass. A high-fiber diet helps to increase stool frequency and prevent many digestive diseases. (29)

Partially defatted flaxseed meal is also an effective natural laxative that can help manage symptoms of constipation in mice. (30)

Flaxseed is Gluten-Free

Milled flaxseed doesn’t contain gluten and, therefore, won’t interfere with your digestion if you have a gluten intolerance.

The International Journal of Food Sciences and Nature reported in 2018 that flaxseed can be added to gluten-free bakery products to improve their nutritional content. (31)

Flaxseed Meal Helps Protect Against Cognitive Dysfunction

The ALA fatty acid content and the presence of lignans in ground flaxseed also help to improve your brain function and deal with stressful conditions better.

Scientists conducted a trial on 35 postmenopausal women using flax seed extracts. Scientists noted that flaxseed supplements helped to reduce mental stress and blood pressure during difficult cognitive tests. (32)

Other studies have shown that alpha-linolenic acid from flax seed also has a positive effect on the brain. Getting enough ALA omega-3 fatty acid can help protect against neurological conditions like anxiety and depression. (33)

Research on rats found that consuming flaxseed while pregnant had a neuroprotective effect on their offspring. (34)

Learn about what are the best natural supplements to take if you suffer from depression, anxiety, or chronic stress.

Flaxseed Meal Is Good for Managing Symptoms of Diabetes

The fact that flaxseed is low in carbs, calories, and high in protein means they are a good food source if you suffer from diabetes.

The journal Kidney International reported on studies that have shown flaxseed to have the potential to prevent complications of diabetes like kidney disease and kidney damage. (35)

Other studies indicate that consuming flax lignan supplements can help to prevent the development of type 2 diabetes in humans. (36)

One study involving diabetics with foot ulcers found that supplementing the diet with 1,000 mg omega-3 flaxseed oil helped the ulcers heal quicker and also improve other diabetes markers. (37)

If you suffer from diabetes or have pre-diabetes conditions, find out what are the best foods to eat to help keep blood glucose under control.

Flaxseed Meal Can Benefit Menopausal Women

Adding ground flax seeds to your diet can help to alleviate many of the symptoms during the menopause.

As well as taking milled flaxseeds during the menopause, find out what other natural supplements can help to relieve your symptoms.

Flaxseed Meal Has Anticancer Properties

Certain compounds in flaxseed extract have been studied for their anticancer activity.

Research in 2018 found that lignans in flaxseeds have a structure similar to estrogen and exert an anti-estrogen activity. Some clinical trials on postmenopausal women have shown that flaxseed consumption can help to lower the risk of breast cancer. (39)

Other studies have shown that men taking 30 g of flaxseed daily can lower their risk of prostate cancer. (40)

Some lab trials have found that the ALA omega-3 content in flaxseed oil can help protect against colon cancer. (41) Lignans in flaxseed also have a protective effect on colorectal cancer. (42)

Of course, more research needs to be done to see how flaxseed and extracts from flax seed meal can be utilized more in cancer treatment.

How to Store Flaxseed Meal?

When you grind flaxseed into a powder, the nutrient value starts to decrease, and the flaxseed oils can become rancid relatively quickly.

You should store whole flax seeds until you want to create flaxseed meal. If you want to grind up more flax seed than you intend to use, place them in the freezer.

How Much Flaxseed to Consume Daily

When consuming flaxseeds for their health benefits, always consume flaxseed meal to make sure you get the most of their health benefits.

Most studies show that consuming up to 50 grams of ground flaxseed daily is safe. This is about 5 tablespoons of whole seed. (5)

5 tablespoons of whole flaxseeds ground into powder will give you 2.8 g of fiber (11% RDI), 2338 mg of omega-3, 40.2 mg of magnesium (10% RDI), 26 mg calcium (3% RDI), and 1.9 g of protein (4% RDI).

How to Use Flaxseeds or Flaxseed Meal

There are many ways that you can add flaxseed meal to your daily diet.

For example, you can grind up a tablespoon of whole flax seeds and add them to your breakfast cereal, yogurt or morning smoothie.

You can sprinkle a desert spoon of flaxseed meal on your sandwich that you have at lunchtime.

If you enjoy baking, then you can add ground flaxseeds to your recipe to increase the nutritional content of baked goods.

It is also possible to make flaxseed water. Add a teaspoon of ground flaxseed to an 8-Fl.oz. glass of water. Leave to stand for 30 minutes until it takes on a gel-like consistency. Drink the flaxseed water first thing in the morning.

You can also sprinkle ground flaxseed on salads, porridge and soups.

Side Effects of Flaxseeds

Flaxseeds are extremely healthy and contain plenty of fiber and nutrients. Because flaxseeds are high in fiber, you may notice that you have more frequent bowel movements. You also may experience side effects of flaxseeds such as bloating or gas.

You should also consume plenty of water when consuming flaxseed meal to prevent the powder from bulking up in your digestive system and blocking your intestines.

There is also some evidence that taking flaxseed in high doses could lower men’s testosterone levels. (43)

  1. Lisa says:

    I put boiling water over a cup of flax seeds and let it soak overnight. I drain and drink the water before each meal, and put the gelled flaxseeds into my smoothing, salsa, oatmeal, or anything else I can think of!

  2. Mae says:

    I tend to steer clear of anything that mentions ‘anti inflammation’ because I have a lung bleeding problem and have had since age 42 and am now 71…have wound up in hospital several times over the years, and so far they have been able to cauterize the vessel that is bleeding…average life span with ‘Massive Hemoptysis’ is 70. Most likely what will cause my demise if one bout of bleeding comes forcefully, causing asphyxiation. I have noticed some products mention ‘strengthens blood vessels’, and other mention ‘increasing blood flow’. Last thing I want is increased blood flow, and I take a good deal of vitamin K-1 to help prevent a bleed. While I have inflammation types such as osteoarthritis, knee/hip pain (and getting worse but don’t dare take many things), I wonder about those that state they ‘strengthen blood vessels’…I wonder if that might prevent them from bleeding, but do not know, so am afraid to take anything that reduces inflammation. Just wanted to mention this dilemma, and I don’t expect any answer, since I doubt if anyone would know the answer. Not easy trying to avoid things that could make one bleed as many things out there can…just wanted to voice what seems to be an unanswerable question…

    • Vee says:

      do you take fibre pills, limited knowledge but believe that would be helpful, are you aware that cayanne pepper can stop a nose bleed and supposedly any bleed.

  3. Karen says:

    It’s important to grind them fresh every day, and also to drink lots of water when you are consuming flax seeds.

  4. janae says:

    Does taking the flaxseed oil have the same health benefits as the seeds

    • Jenny says:

      The seeds and the oil don’t have the same benefits, for example the fiber in the seeds promotes healthy digestive system but the oil itself doesn’t contain fiber.

  5. Shanni says:

    Flaxseeds do work for weight loss. i have lost about 20lbs just using flaxseeds and husks. It also helps with constipation. Remember that flaxseed oil is different from the actual flaxseeds. If I ever dont have time to do a flaxseed shake, I take the Lady Soma Detox which is like super flaxseed and husks. Thats definitely the quickest way – but also including flaxseeds in your meals helps as well.

  6. Sadhan Ghosh says:

    Where can I purchase flaxseed? Please inform me.

  7. Anne says:

    I grind extra flaxseeds and put it in the fridge so it does not go rancid. We then sprinkle it on porridge and yogurt or you could put it on rice pudding and other desserts.

  8. donna-marie says:

    can you take flaxseed oil capsules

    • Jenny Hills says:

      Flaxseed oil capsules lack the fiber and other nutrients that the seeds have, so they don’t have the same benefits.

  9. Ken says:

    I buy mine Ground , The are called Prewett,s Ground Golden Flax seeds and I,ve been getting stronger without actually doing any exercise.
    I add a full teaspoon to plain yogurt twice a day .
