Two studies which were similar in protocol were conducted.
Following a preliminary baseline period of 7 days, in which the
subjects consumed their self-chosen diets, they received 3 eggs daily
for 4 weeks. Depending upon the changes in plasma cholesterol in
response to 3 eggs daily, the subjects in studies A and B were
divided into 2 groups. During the subsequent 4 week treatment
period, the hyporesponders received 6 eggs daily in study A, and 3
eggs and additional butter daily in study B. The hyperresponders
consumed 3 eggs daily in study A; and 3 eggs with additional high
PUFA margarine in study B. Dietary records were taken during the
last 7 days of each period. A total of 128 seven-day dietary records
kept by these subjects indicated that the majority of them met the
RDA's for the nutrients studied, except vitamin B6 and folacin.
Vitamin B6 intakes were below 67% of the RDA in 13% of the diets, and
were below 67% of the RDA for folacin in 21% of the diets. There was
a problem in meeting 67% of the RDA for zinc in subjects who consumed less than 70 g. of protein daily.
When the subjects added 3 whole eggs daily to their self-chosen
diets, there were significant increases in protein (p<0.05), total
fat (p<0.01), phosphorous (p<0.01), sodium (p<0.001), iron (p<0.05),
and dietary cholesterol (p<0.0001). A significant decrease in
non-egg dietary cholesterol (p<0.01) was also observed. There were
no significant differences in nutrient intake between hypos and
hypers in either the baseline or classification periods. No further
changes in nutrient intakes were seen in the 9 subjects who continued
consuming 3 added eggs daily during treatment period. The 13
hyporesponders who added 6 eggs daily to their self-chosen diets had
significant increases, compared to baseline, in protein (p<0.05),
total fat (p<0.05), and dietary cholesterol (p<0.0001) and
significant decreases in carbohydrate (p<0.01), thiamin (p<0.05), and
vitamin B6 (p<0.05). Other than obvious increases in total fat, no
other changes in nutrient intake were observed upon the addition of
butter or margarine. The use of nutritional supplements was observed
in 71% of the subjects: 58% regularly and 13% occasionally. All
subjects who took supplements included vitamin C. In general,
nutrient supplements did not improve poor nutrient intakes. These
results show overall adequacy of the diets for most of the men, which
is consistent with other studies. The effects of additional egg in
the diet were increases in protein, fat and cholesterol intakes and a
decrease in carbohydrate consumption. / Graduation date: 1985
