Flax Seeds Benefits

1. One of the best digestive aids available

Of flax seeds 29% carbohydrate content, 95% of that comes in form of fiber, which is essential for healthy digestion. However, flax seeds are a very low carbohydrate food, being that only 1.5% of the carbohydrate content is digestible (hence the high fiber content). Only 2 tablespoons of flax seeds provides almost 25% of the RDA for fiber (1), and can be extremely helpful in regulating bowel movements, promoting healthy gut bacteria and works as a natural and safe laxative, when taken in liquid form (mixed with water or juice). Remember, adequate dietary fiber is also key for achieving and maintaining healthy cholesterol levels (2), yet another reason flax seeds should be consumed regularly.

2. Packed full of healthy fats

Flax seeds offer a healthy dose of high quality fats, mainly consisting of polyunsaturated fatty acids, specifically omega 6 and anti-inflammatory omega 3 fatty acids (alpha linoleic acid, otherwise known as ALA). ALA is an essential fatty acid, meaning we must obtain it from food sources as it cannot be produced by the body. Flax seeds actually beats chia seeds in its ALA content, making it an incredibly anti-inflammatory superfood.

Remember though, ALA must be converted to DHA and EPA in order to be effectively used by the body, and these processes are often not efficient. However, flax seeds are the best plant based source of omega 3 fatty acids.

3. Excellent source of important vitamins and minerals

Not only are flax seeds high in omega 3 fatty acids, but they also offer a wide array of health promoting nutrients. The top nutrients obtained from this superfood are copper, vitamin B1, molybdenum, phosphorous and magnesium. Magnesium is particularly critical for managing stress and healthy sleep patterns.

4. Flax seeds can help you lose weight

Because of flax seed’s high soluble fiber content, they can make a addition to a diet that is aiming to lose weight. Soluble fiber has been shown to help control appetite, mainly by reducing cravings and making us feel more satiated (3). Flax seeds also work to cool systemic inflammation in the body, which in and of itself can help in weight management (4).

5. Supports cardiovascular health

Largely due to their omega 3 fatty acid content (but also lignans and fiber), flax seeds have been proven to improve and support heart health in several different ways. Multiple studies have shown flax seeds ability to lower LDL cholesterol (bad cholesterol) by up to 18%, which is an indicator for heart disease (5). This works because the lignan and fiber content of flax seeds bind to cholesterol molecules to escort them through the digestive tract until they are eliminated. Omega 3 fatty acids are known to promote heart health by decreasing blood pressure, risk of stroke and heart attacks.

Uses of Flax Seeds

1. Add flax seeds to a smoothie

Flax seeds make an excellent addition to any smoothie, but make sure they are ground first. Buying the whole seed and grinding them yourself in a coffee grinder is ideal (less chance for the delicate fats to oxidize when exposed to heat), but buying pre-ground is another option. Add approximately 2 tablespoons to any smoothie, and reap the many benefits.

2. Combine ground flax seeds into your morning yogurt or oatmeal

For a digestive and nutrient boost first thing in the morning, add 2 tablespoons of ground flax seeds to whole, plain yogurt with a bit of fruit (add honey as a sweetener if needed), or combine the same amount of flax to a bowl of oatmeal. Flax seeds have a nutty taste, and work quite well as an accompaniment to a breakfast dish.

3. Use flax seeds in baking

One of the great things about this superfood is that it can be added to traditional baked goods to greatly up its nutritional value. Try making a high fiber pumpkin flax muffin, or add it to any bread or other recipe (ideally using honey or maple syrup as a sugar alternative. Because of flax seed’s taste and texture, it can often be added to recipes without any noticeable difference to the final product.

4. Add ground flax seeds as an egg substitute

For those who don’t or can’t eat eggs (although for those that can, remember that eggs are also a superfood), ground flax seeds can make a great alternative in recipes calling for eggs. Simply add 1 tablespoon of ground flax with 3 tablespoons of water for each egg, and mix thoroughly. Flax seeds expand in water and have a gummy, binding ability, so in this way can work well as an egg replacement.

5. Sprinkle flax seeds on top of vegetables

One of the easiest ways to incorporate flax into your daily diet is to simply sprinkle them on top of raw or cooked veggie dishes. Always add them at the end of cooking, as heating flax seeds or oils should be avoided as much as possible, as their delicate polyunsaturated fats can oxidize at high temperatures, creating free radicals in the body.

Possible Side Effects of Flax Seeds

Flaxseed is considered safe for most adults when taken in food or beverage form, however as with any food, certain considerations should always be considered.

  • Bloating & Stomach Distress: Due to the high fiber content, flaxseeds have the potential to cause an increase in bowel movements which can lead to bloating, and possible diarrhea. Whole flaxseeds should also be avoided if you have diverticulitis. For those with preexisting digestive issues, introduce flax seeds (always ground) to the diet slowly, starting with just 1 teaspoon, and slowly increasing over time.
  • Low Blood Pressure: Since flaxseeds can help to reduce blood pressure, it is not advised to consume flaxseeds if you have low blood pressure or are taking blood pressure medications. Check with your doctor to see if low doses are safe for you.
  • Pregnancy & Breastfeeding: Flax seeds are high in lignans, which are chemicals that can mimic the activity of oestrogen in the body. There is little conclusive research as to whether flax seeds could potentially harm a baby while in utero or breastfeeding, but normal amounts are generally considered safe. However, it is best to avoid supplements containing flax seed oil or eating extremely large quantities.
  • Blood clotting disorders: Since flaxseeds can potentially slow the body’s blood clotting abilities, it is advised to avoid consuming flaxseeds if you have a bleeding disorder.
