Queenie,
i do it to keep my system clear.. so it helps in my digestion and my complexion. if i eat too much saefood or egg.. over a period of time, i get red bumps all over my back. there are not pimples and have no yellow pus.. its just body toxins...
so i do this quite regularly.. about once in a quarter.. i used to do it 3 days every month.
during these 3 days, no caffeine, no red meat, no stir fries, no deep fried and oily food.. just fish soup, clear soup stuff or porridge..
after these 3 days, i continue eating light food for a few more days before i slowly introduce oily food to body, cos intestines are cleansed.
good to do this to reduce risk of getting colon cancer.. cos once kena... we may just die in 6 mths time..
