Objective: A 'ginger vinegar soup' and other special dietary practices have
been traditionally recommended for postpartum Chinese women. This paper de
scribes these practices in the first 6 weeks postpartum, and details of the
calcium and iron content of the 'ginger vinegar soup'.
Design and subjects: Results of this paper were generated from a longitudin
al study on the nutritional status of Hong Kong Chinese postpartum women. '
Ginger vinegar soup' samples were collected at the 2 week home visits. Calc
ium and iron content were measured by the combination of dry ashing method
and atomic absorption spectrophotometry Results were compared with other ty
pes of soup and food sources. A food frequency questionnaire was completed
at the 6 week interview to assess the special dietary practices during this
period.
Results: Fifty-one subjects completed the food frequency questionnaires. Tw
enty-two ginger vinegar soup samples and six other soup samples were collec
ted. Consumption of special food items such as ginger, pig's trotters, egg
and chicken varied greatly among subjects. More poultry and similar amounts
of egg were consumed by our subjects as compared with the Hong Kong genera
l population. Chicken soup and ginger vinegar soup were commonly consumed.
Median calcium and iron contents of the ginger vinegar soup were 4.65 and 0
.84 mg/dl, respectively. This calcium content was higher than that of the o
ther six soup samples, but was low as compared with other calcium-rich food
s. Iron content of ginger vinegar soup was higher than that of the other si
x samples and was comparable to some iron-rich foods.
Conclusions: Hong Kong Chinese postpartum women followed traditional dietar
y practices to different degrees. These practices were characterized by an
increased poultry consumption. Iron content of ginger vinegar soup was comp
arable to some iron-rich foods.
