Postpartal weight loss, nutritional intake, and immune status were exa
mined in 65 women. Although 80% of the women last weight and were not
overweight by the 4th postpartal mouth, the majority had diets that we
re inadequate in fat content (greater than or equal to 30% of calories
from fat) or protein content (less than or equal to 12% of calories f
rom protein), or in terms of caloric intake (less than or equal to 1,2
00 calories or greater than or equal to 2,200 calories). Differences i
n some immune cell subsets were noted between women with high-fat and
normal-fat diets. Women with high-fat diets had lower percentages of s
pecific immune cell subsets than women with normal-fat diets. Protein
intake was not related to immune cell phenotypes.
