The hypocholesterolemic effects of oat bran and karaya gum were investigated among hypercholesterolemic women aged 41 to 66 years. Seven women were fed 94 g oat bran per day in the form of three muffins (56 g oat bran) and one serving of hot cereal (38 g), and 6 women were fed 10 g karaya gum whipped with fruit juice or fruit-yogurt per day for three weeks, providing 6.6 g soluble fiber from oat bran and 9.9 g soluble fiber from karaya gum. Fasting mean serum total cholesterol, LDL-cholesterol, and triglyceride were significantly lowered in the oat bran group (p < 0.05). In the karaya gum group, 4 of the 6 subjects experienced a decrease in serum total cholesterol and LDL-cholesterol, but the overall reduction of 8% was not significant. Mean serum HDL-cholesterol was slightly lowered in the oat bran group but decreased significantly (12%) in the karaya gum group (p < 0.05). These changes are attributed only to the inclusion of fiber sources in the diet since no significant changes occurred in the subjects' BMI, total daily calories, fat or cholesterol intake, or exercise pattern. Phases of the menstrual cycle for different subjects did not contribute to variations observed in any of the serum parameters since menstruating women were within four days of each other's menstruation and were equally distributed among the two groups.
