The occurrence of hot flash has always been a question to many researchers and doctors, and, the addition of its minimal rate in Asia has created many hypothesis from some of them. In fact, even with the warm weather in this region, women in Asia rarely experience the dread of hot flashes during menopause.

Some studies suggest, this is due to the difference in diet. There are a number of food included in the Asian daily diet, that contain significant vitamins and minerals which combat hot flashes. Soy, for example, is an element that is added to many dishes served in Asian homes. Soy contains the compounds genistein and daidzein which are estrogenic. Aside from soy, their meals are also partial towards green leafy vegetables, whole grain and sea vegetables, which are known to replenish electrolytes, lost through perspiration during flashes.

Although not yet proven, a healthy diet is suggested by many doctors, to at least replenish whatever is lost during hot flashes, and to avoid any further health complications.
