The Benefits of Flaxseed

By Elaine Magee, MPH, RD

Is flaxseed the new wonder food? Preliminary studies show that it may help fight heart disease, diabetes and breast cancer.

Some call it one of the most powerful plant foods on the planet. There’s some evidence it may help reduce your risk of heart diseasecancerstroke, and diabetes. That’s quite a tall order for a tiny seed that’s been around for centuries.

Flaxseed was cultivated in Babylon as early as 3000 BC. In the 8th century, King Charlemagne believed so strongly in the health benefits of flaxseed that he passed laws requiring his subjects to consume it. Now, thirteen centuries later, some experts say we have preliminary research to back up what Charlemagne suspected.

Flaxseed is found in all kinds of today's foods from crackers to frozen waffles to oatmeal. The Flax Council estimates close to 300 new flax-based products were launched in the U.S. and Canada in 2010 alone. Not only has consumer demand for flaxseed grown, agricultural use has also increased. Flaxseed is what's used to feed all those chickens that are laying eggs with higher levels of omega-3 fatty acids.

Although flaxseed contains all sorts of healthy components, it owes its primary healthy reputation to three of them:

  • Omega-3 essential fatty acids, "good" fats that have been shown to have heart-healthy effects. Each tablespoon of ground flaxseed contains about 1.8 grams of plant omega-3s.
  • Lignans, which have both plant estrogen and antioxidant qualities. Flaxseed contains 75 to 800 times more lignans than other plant foods.
  • Fiber. Flaxseed contains both the soluble and insoluble types.

The Health Benefits of Flax

Although Lilian Thompson, PhD, an internationally known flaxseed researcher from the University of Toronto, says she wouldn’t call any of the health benefits of flax "conclusively established," research indicates that flax may reduce risks of certain cancers as well as cardiovascular disease and lung disease.

Cancer

Recent studies have suggested that flaxseed may have a protective effect against breast cancerprostate cancer, and colon cancer. At least two of the components in flaxseed seem to contribute, says Kelley C. Fitzpatrick, director of health and nutritionwith the Flax Council of Canada.

In animal studies, the plant omega-3 fatty acid found in flaxseed, called ALA, inhibited tumor incidence and growth.

The lignans in flaxseed may provide some protection against cancers that are sensitive to hormones without interfering with the breast cancer drug tamoxifen. Thompson says some studies have suggested that exposure to lignans during adolescence helps reduce the risk of breast cancer and may also increase the survival of breast cancer patients.

Lignans may help protect against cancerby blocking enzymes that are involved in hormone metabolism and interfering with the growth and spread of tumor cells.

Some of the other components in flaxseed also have antioxidant properties, which may contribute to protection against cancer and heart disease.

Cardiovascular Disease

Research suggests that plant omega-3s help the cardiovascular system through several different mechanisms, including anti-inflammatory action and normalizing the heartbeat. Fitzpatrick says new research also suggests significant blood pressure-lowering effects of flaxseed. Those effects may be due to both the omega-3 fatty acids as well as the amino acid groups found in flaxseed.

Several studies have suggested that diets rich in flaxseed omega-3s help prevent hardening of the arteries and keep plaque from being deposited in the arteries partly by keeping white blood cells from sticking to the blood vessels’ inner linings.

"Lignans in flaxseed have been shown to reduce atherosclerotic plaque buildup by up to 75%," Fitzpatrick says.

Because plant omega-3s may also play a role in maintaining the heart’s natural rhythm, they may be useful in treating arrhythmia (irregular heartbeat) and heart failure. More research is needed on this.

Eating flaxseed daily may also help your cholesterol levels. The level of LDL or "bad" cholesterol in the bloodstream has been linked to an increased risk of heart diseaseobesitydiabetes, and metabolic syndrome. A study of menopausal women showed a decrease in LDL level after the women ate 4 tablespoons of ground flaxseed each day for a year. Fitzpatrick says the cholesterol-lowering effects of flaxseed are the result of the combined benefits of the omega-3 ALA, fiber, and lignans.

Diabetes

Preliminary research also suggests that daily intake of the lignans in flaxseed may modestly improve blood sugar (as measured by hemoglobin A1c blood tests in adults with type 2 diabetes).

InflammationTwo components in flaxseed, ALA and lignans, may reduce the inflammation that accompanies certain illnesses (such as Parkinson's disease and asthma) by helping block the release of certain pro-inflammatory agents, Fitzpatrick says.ALA has been shown to decrease inflammatory reactions in humans. And studies in animals have found that lignans can decrease levels of several pro-inflammatory agents.Reducing inflammation associated with plaque buildup in the arteries may be another way flaxseed helps prevent heart attack and strokes.Hot Flashes

One study of menopausal women, published in 2007, reported that 2 tablespoons of ground flaxseed mixed into cereal, juice, or yogurt twice a day cut their hot flashes in half. The intensity of their hot flashes also dropped by 57%. The women noticed a difference after taking the daily flaxseed for just one week and achieved the maximum benefit within two weeks.

But another study reported no significant reduction in hot flashes between postmenopausal women and breast cancer patients eating a bar containing 410 milligrams of phytoestrogens from ground flaxseed and women eating a placebo bar.

The results, says Thompson, are consistent with other studies that have shown no siginifcant difference in the effect on hot flashes between flaxseed and placebo

Flaxseed Isn't a Magic Bullet

It's tempting to think of flaxseed as a super food because of its many potential health benefits. But keep in mind there is no magic food or nutrient that guarantees improved health.

What matters is consistently making great dietary choices as part of an overall healthy lifestyle.

Who Shouldn’t Use Flaxseed?

Until more is known, Thompson says, pregnant women and possibly breastfeeding mothers should not supplement their diets with ground flaxseed.

"Our own animal studies showed that flaxseed exposure during these stages may be protective against breast cancer in the offspring. But a study of another investigator showed the opposite effect," Thompson says.
