The plasma concentrations and the dietary intakes of vitamin E
were determined in 20 elderly and ten young subjects. Five subjects
in the older group were known to take supplements of vitamin E. The
mean concentration of tocopherols (determined chemically) in the
plasma of all unsupplemented subjects was 1.12 ±...
Plasma vitamin B₁₂ concentrations of 16 elderly women were
measured using the growth response of the microorganism, Ochromonas
malhamensis. The method required major modifications which
are described in detail. All women had plasma concentrations of
vitamin B₁₂ above the normal minimum of 200 pg/ml despite the fact
that the diets...
Adult male guinea pigs were maintained on four dietary regimens
for a period of 8 weeks. The basic diet consisted of powdered guinea
pig chow with 10% coconut oil. The three experimental groups
received the basic diet with additions of either 1% lecithin, 0.25%
cholesterol, or 0.25% cholesterol plus 1%...
Folic acid and ascorbic acid status have been assessed in
twenty non-institutionalized elderly subjects with respect to both
hematological and dietary aspects.
The hemoglobins, hematocrits, and serum ascorbic acid
concentrations were within the normal range. A few subjects had
total serum protein concentrations which were less than the acceptable
level....
Ninety people, aged 60 and older, were interviewed regarding
their shopping habits, use of convenience foods, frequency of food
use and reasons for food preferences. The relation of income level
and education level to reasons for food use was also investigated.
The major source of purchased food was the chain...
Activities of lipoprotein lipase (LPL) and hormone-sensitive
lipase (HSL) in adipose tissue, accumulation of carcass fat, and
serum triglyceride have been determined in meal-fed (MF) and
ad libitum-fed (AD) rats. At each feeding frequency, the animals
received diets providing total fat as 15% or 30% of calories and
polyunsaturated fatty...
The effect of oral lecithin supplementation on plasma lipids
was investigated. Thirty-one healthy middle-aged men received 7.2
gm soy lecithin daily for two months. Blood was drawn both before
and after supplementation and analyzed for total and esterified
cholesterol, total and individual phospholipids, total lipids, triglycerides,
and lecithin:cholesterol acyltransferase (LCAT)...
The effect of supplementary lecithin on plasma lipids
was studied. Thirty-one men between the ages of 38 and 56
were given 7.2 gm of supplemental lecithin per day in the
form of Soya Lecithin. Supplementation lasted for a period
of seven and a half to eight weeks. Blood was analyzed...
The effects of fermentation on selected nutrients in the seed
of the African locust-bean were investigated. The protein content
of the seeds declined from 50.1% of dry weight in the unfermented
sample to 32.4% of dry weight in the fully fermented sample.
Methionine, cystine, and tryptophan were the limiting amino...
The effects of improved oral hygiene on the nutrition of 23
elderly institutionalized men and women were investigated. An experimental
group of 12 received professional oral hygiene treatments
three times weekly for a period of five weeks, while a control group
of 11 received only placebo work. Changes in taste...
The interrelationships between physical measurements, dietary
intake of specific nutrients, and plasma lipids were examined in 19
healthy elderly subjects. The mean blood pressures, relative weights,
and skinfold thicknesses were within normal ranges, although women
tended to be more overweight. Systolic pressure and relative weight
were associated with increased body...
