Hot Flash Newsflash II

Even people who don't cotton to tofu usually find soy nuts palatable. The hard, toasted seeds taste sort of like a cross between peanuts and pretzels. It now turns out that as snacks go, these may have an extra benefit--at least for women experiencing menopausal symptoms. Eating a handful of soy nuts at various times throughout the day cut the number of hot flashes they experienced by at least 40 percent.

The study recruited 60 heathy postmenopausal Boston-area women to take part in a pair of eight-week dietary sequences. In one, they ate a low-fat, high-carbohydrate diet rich in calcium and fish. In the other sequence, they ate this diet supplemented with a half-cup of soy nuts each day, with the "nuts" to be spread out in three or four portions several hours apart. Half started on the diet without soy nuts, the rest on the soy-supplemented one.

In addition to experiencing fewer hot-flash episodes while they were in the soy-nut phase of the trial, the recruits also reported fewer other physical and emotional symptoms of menopause. Francine K. Welty and her colleagues at Beth Israel Deaconess Medical Center in Boston report their team's findings in the April Journal of Women's Health.

The amount of soy and its consumption throughout the day were each intended to mimic, in part, the typical day-long intake of soy in many Asian cultures, where the prevalence of hot flashes is low. Indeed, Welty's group notes, an estimated 10 to 25 percent of Chinese and Indonesian women typically experience this menopausal symptom compared to some 60 to 90 percent of women in Western countries.

I happened onto this paper while I was taking advantage of a nice offer by the publisher of this journal.
