The relationship between soy product intake and serum total
cholesterol concentration was examined in 1,242 men and 3,596
women who participated in an annual health check-up program in
Takayama City, Japan, provided by the municipality in 1992. The
intake of soy products and various foods and nutrients was
assessed by a semiquantitative food-frequency
questionnaire.
Blood samples were collected from fasting subjects to measure the
serum total cholesterol concentration. A significant trend (P for
trend = 0.0001) was observed for decreasing total cholesterol
concentration with an increasing intake of soy products in men
after controlling for age, smoking status and intake of total
energy, total protein and total fat.
This negative trend (P for trend = 0.0001) was also noted in
women after controlling for age, menopausal status, body mass
index and intake of total energy and vitamin C. An additional
adjustment for physical activity, coffee and tea consumption, and
intake of cholesterol, carbohydrates, fiber and vitamin E did not
change the results. These data suggest a role for soy products in
human cholesterol homeostasis.
