Dietary data from a prospective study were used to relate factors influencing calcium balance (estimates of dietary calcium intake, protein intake from nondairy animal sources (meat, fish, and eggs), and coffee consumption) to the incidence of hip fracture. During the years 1977-1983, women and men born between 1925 and 1940 and living in one of three(More)
In the course of the last decade peroxisomal beta-oxidation has emerged as a metabolic process indispensable to normal physiology. Peroxisomes beta-oxidize fatty acids, dicarboxylic acids, prostaglandins and various fatty acid analogues. Other compounds possessing an alkyl-group of six to eight carbon atoms (many substituted fatty acids) are initially(More)
We have compared the effects of partially hydrogenated fish oil (PHFO-diet), partially hydrogenated soybean oil (PHSO-diet), and butterfat (butter-diet) on serum lipids and lipoprotein[a] in 31 young men. The three test margarines, which contributed 78% of total fat in the diets, were produced from 70% of butterfat, PHSO, or PHFO, each with 30% of soybean(More)
We have compared the effects on lipoproteins and haemostatic variables of two hard margarines with similar functional properties, one traditional margarine containing partially hydrogenated fish oil (PHFO), and one experimental margarine based on vegetable oil (VO). Both were all-purpose cooking margarines with nearly identical functional properties. Trans(More)
We have compared the effects of partially hydrogenated fish oil (PHFO diet), partially hydrogenated soybean oil (PHSO diet), and butterfat (butter diet) on fibrinolytic and coagulation variables in 31 young men. The three test margarines, which contributed 78% of total fat in the diets, contained 70% butterfat, PHSO, or PHFO, each with 30% of soybean oil.(More)
Dietary intake (24-h recall), dietary supplementation practice and relative weight (BMI) were investigated in a random sample of 257 independent-living elderly persons above 75 years. The proportion of energy from fat was unfavorably high among women (41.7%), while diet nutrient density was similar for men and women. Mean intakes of vitamin D, thiamin and(More)
OBJECTIVES To investigate the association between composition of serum free fatty acid (FFA) fraction and risk of a first myocardial infarction (MI). DESIGN A case-control design. SETTING The patients were recruited from Ullevål Hospital in Oslo and Ostfold Central Hospital in Fredrikstad and Sarpsborg, Norway. SUBJECTS A total of 103 patients with(More)
OBJECTIVES In the present study the diet and the nutritional status of pregnant Pakistani immigrant women have been compared with a group of Norwegian women. DESIGN A cross-sectional survey of women in the 18th week of pregnancy. SETTING Women referred to routine ultrasound examination at Aker and Ullevål Hospitals in Norway. SUBJECTS All (58) healthy(More)
The conversion of 3 alpha,7 alpha,12 alpha-trihydroxy-5 beta-[3H]cholestanoic acid into cholic acid and 3 alpha,7 alpha-dihydroxy-5 beta-[3H]cholestanoic acid into chenodeoxycholic acid has been studied in subcellular fractions of human liver. The products were separated from the substrates by high-pressure liquid chromatography and identified by combined(More)
A nutritional study was carried out of 16 independent-living elderly (9 women, 7 men) suffering from dementia and a control group matched for sex and age. The study consisted of interview (with participants or relatives/home helps), a 3-d weighed dietary record and biochemical determinations of blood components. No significant difference in mean daily(More)
