While replacement of dietary saturated fat with unsaturated fat has been advocated
to reduce cardiovascular disease risk, diets high in polyunsaturated fatty acids
(PUFA) could increase low density lipoprotein (LDL) susceptibility to oxidation,
potentially contributing to the pathology of atherosclerosis. To assess in vivo lipid
peroxidation and susceptibility, of LDL...
The objective of this study was to compare the effects on eating behavior,
lipids, lipoproteins, lipid peroxidation, and glycemic control in women with type 2
diabetes of a high-monounsaturated fat diet (HM) compared to a high-carbohydrate
In an outpatient feeding study, ten hypertriglyceridemic postmenopausal type
2 diabetic women...
The effect of vitamin B-6 (B-6) status on plasma fatty acids (FA) levels and lipid
metabolism was investigated in this metabolic study. Eight female subjects were fed for 28
days. For the first 7 days, they were fed a constant diet containing 2.10 mg of B-6. For the
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...
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 ±...
The bioavailability of vitamin B-6 from four selected
foods was investigated in five men, aged 22 to 25 years,
who were receiving a pyridoxine supplement. The subjects
received a constant diet containing 1.34 mg of vitamin B-6
throughout this five-week study, except on Saturdays and
Sundays when they ate their...
This investigation was designed to add to present understanding
of vitamin B-6 (B6) metabolism during exercise. Ten women, 5
aerobically trained and 5 untrained, were fed 4 controlled diets: a
moderate carbohydrate (49%) (MCHO) for 2 weeks, a high carbohydrate
(63%) (HCHO) for one week, MCH0+B6 for 2 weeks, and...
Four studies were conducted to evaluate the effect of varying levels of vitamin
B-6 (B6), protein and pyridoxine glucoside (PNG) on B6 status and requirements of
women. In the first two studies, women were fed a constant protein diet and vitamin
B-6 intakes of 0.84 to 2.39 mg/d during 10-...
The effect of pyridoxine (PN) supplementation on lymphocyte
responsiveness was investigated in 15 elderly volunteers (aged
65-81 years) by measuring lymphocyte proliferation to T and B cell
mitogens, lymphocyte subpopulations with monoclonal antibodies
(T3, T4, T8) and plasma pyridoxal 5'-phosphate (PLP) concentration
at pre-supplementation and after 1 and 2 months...
