Soy may reduce hot flashes during menopauseSoy may reduce discomfort during menopause, according to a recent Italian study. Isoflavones, natural plant elements of soy, can reduce hot flashes. This effect was observed after only six weeks, regardless of the severity of hot flashes.
Annually, millions of women worldwide experience menopause. Menopause symptoms vary from woman to woman, but hot flashes are experienced by most women as very disturbing. Hot flashes typically begin 1 to 5 years after the absence of menstruation. In Western countries, 70% of women experience hot flashes during menopause. Remarkable is the lower rate among Asian women: only 5 to 18% of them suffers from hot flashes. It is thought that the higher consumption of isoflavones - natural plant ingredients from soy - in Asian countries play a role. The results of a recently published Italian study confirm this suspicion.
