Then what does fibers really do.
Fibers are those in plants that can’t be absorbed in the gastrointestinal tract. Even not so nutritious by itself, fiber does an important job in maintaining the ideal gastrointestinal environment and providing a normal gastrointestinal function.
However, supplemental fiber can’t replace fiber from food source, because of the concomitant ingestion of other important nutrients such as vitamins, minerals and proteins in fiber rich diet. In medicine, fiber is thought to maintain good blood levels of glucose and cholesterol. In integrative medicine, fiber bring away toxicities and ease off liver function; it balances yin and yang therefore also the hormone balance such as estrogen versus progesterone.
Shortage of progesteron
As the yang that balanced estrogen yin, progesterone is easily burned out by stress. Medically significant symptoms of low levels of progesterone are shortage of luteal period, delay of cervical mucus turning into thicker sticky fluid and spotting before the periods.
Those who may suffer from relative estrogen dominance such as liver conditions, fibroids, endometriosis, dysmenorrhea (PMS and irregular peroid: both metrorrhagia and oligomenorrhea), headache before period and some thyroid issues.
