Canadian Data Indicate Expectant Mothers Taking Flaxseed Oil Increase Risk of Premature Birth

A study has found that the risks of a premature birth quadruple if flaxseed oil is consumed in the last two trimesters of pregnancy.

The research was conducted by Professor Anick Berard of the Universite de Montreal Faculty of Pharmacy and the Sainte-Justine Hospital Research Center and Master’s student Krystel Moussally.

In Canada, 50 percent of pregnant women take prescription medication. Yet many of them prefer to use natural health products during the pregnancy. “We believe these products to be safe because they are natural. But in reality, they are chemical products and we don’t know many of the risks and benefits of these products contrarily to medication,” says Berard.

Berard and Moussally set out to conduct one of the largest studies ever undertaken by analyzing data from 3,354 Quebec women.

The first part of the research established that:

• Close to 10 percent of women between 1998 and 2003 used natural health products during their pregnancy.

• Before and after pregnancy they were respectively 15 and 14 percent [likely] to use these products.

• Th[is] means that about a third of women consuming natural health products stopped during the pregnancy.

The most consumed natural health products by pregnant women [of the 10% taking some herbal] are:

• Chamomile (19 percent),

• Green tea (17 percent),

• Peppered mint (12 percent),

• And flaxseed oil (12 percent).

Berard and Moussally correlated these products to premature births and only one product had a very strong correlation: flaxseed oil.

“In the general population, the average rate of premature births is 2 to 3 percent. But for women consuming flaxseed oil in their last two trimesters that number jumps up to 12 percent,” says Bérard. “It’s an enormous risk.”

The correlation existed only with flaxseed oil, yet women consuming the actual seed were unaffected. Even if more studies must be undertaken to verify these results, Bérard recommends caution when it comes to consuming flaxseed oil.
