Eating flaxseed may not ease menopausal hot flashes after all, despite some promising early evidence that it might, according to a U.S. study.

Researchers at the Mayo Clinic in Rochester, Minnesota found that 188 women who were randomly assigned to eat a daily flaxseed bar saw no more improvement in their hot flashes than women given flax-free "placebo" bars.

Over six weeks, more than one-third of the women in each group had a 50 percent reduction in the frequency and severity of their hot flashes.

The similar results in both groups suggest a placebo effect or some other explanation for the changes some women reported, said researchers led by Debra Barton, whose findings were reported in the journal Menopause.

"What women should take from this study is that there is little compelling information to try flaxseed if the objective is to reduce hot flashes," Barton told Reuters Health in an email.

In an earlier pilot study, Barton and her colleagues had found that women who consumed flaxseed did see their hot flashes wane, on average.

But that study had no comparison group of women taking a placebo, she noted.
