Flax Seed: The Low Carb Whole Grain

Nutrition, Health Benefits of Flax Seed

By Laura Dolson, About.com Guide  November 16, 2010

It may be tiny, but it’s mighty: The flax seed carries one of the biggest nutrient payloads on the planet. And while it’s not technically a grain, it has a similar vitamin and mineral profile to grains, while the amount offiber, antioxidants, and Omega-3 fatty acids in flax leaves grains in the dust.

Additionally, flax seed is very low in carbohydrates, making it ideal for people who limit their intake of starches and sugars. And its combination of healthy fat and high fiber content make it a great food for weight loss and maintenance - many dieters have found that flax seed has been a key to keeping them feeling satisfied.

Flax Seed Nutrition

Yes, flax seed is high in most of the B vitamins, magnesium, and manganese, but this little seed is just getting started. There are three additional nutrient groups which flax seed has in abundance, and each has many benefits.

Flax Seed is Rich in Omega-3 Fatty Acids: Omega-3 fatty acids are a key force againstinflammation in our bodies. Mounting evidence shows that inflammation plays a part in many chronic diseases including heart disease, arthritis, asthma, diabetes, and even some cancers. This inflammation is enhanced by having too little Omega-3 intake (such as in fish, flax, and walnuts), especially in relation to Omega-6 fatty acid intake (in oils such as soy and corn oil). In the quest to equalize the ratio of these two kinds of oils, flax seed can be a real help. 

Most of the oil in flax seeds is alpha linolenic acid (ALA). ALA is an Omega-3 that is a precursor to the fatty acids found in salmon and other fatty cold-water fish (called EPA and DHA). Because not everyone is able to easily convert ALA into EPA and (especially) DHA, it is best not to rely solely on flax for your Omega-3 intake. However, ALA also has good effects of its own, and definitely helps in the Omega 3/6 balance. 

Flax Seed is High in Fiber: You’d be hard-pressed to find a food higher in fiber - both soluble andinsoluble - than flax. This fiber is probably mainly responsible for the cholesterol-lowering effects of flax. Fiber in the diet also helps stabilize blood sugar, and, of course, promotes proper functioning of the intestines. 

Flax Seed is High in Phytochemicals: Flax seed is high in phytochemicals, including many antioxidants. It is perhaps our best source of lignans, which convert in our intestines to substances that tend to balance female hormones. There is evidence that lignans may promote fertility, reduce peri-menopausal symptoms, and possibly help prevent breast cancer. In addition, lignans may help prevent Type 2 diabetes.

Note that a) flax seeds need to be ground to make the nutrients available (otherwise they just “pass through”) and b) flax seed oil alone contains neither the fiber nor the phytochemicals of whole flax seed meal.
