BACKGROUND Intake of fish oil and oily fish has been reported to improve clinical symptoms in people who have rheumatoid arthritis. Whether the intake of oily fish and fish oil might also protect against the development of rheumatoid arthritis is not known. OBJECTIVE We investigated the association between intake of oily fish and fish oil supplements and(More)
OBJECTIVE We investigated whether life-long adherence to a vegetarian diet is associated with adult height, age at menarche, adult body weight and body mass index (BMI), used as indicators of growth, development and obesity, in a large sample of adults. DESIGN This was a cross-sectional study. Anthropometric data and information on age, ethnicity,(More)
BACKGROUND AND AIM This study examined the prevalence of the metabolic syndrome and its association to lifestyle factors in 60-year-old men and women, with special emphasis on physical activity (PA). METHODS AND RESULTS Every third 60-year-old man and woman in the Stockholm County, Sweden, was invited to a survey of cardiovascular risk factors.(More)
Fatty acid composition of serum lipids and adipose tissue triacylglycerols (AT-TAG) partly reflect dietary fatty acid intake. The fatty acid composition is, besides the diet, also influenced by desaturating enzymes that can be estimated using product-to-precursor fatty acid ratios. The interrelationships between desaturase indices derived from different(More)
Vegetarian diets do not contain meat, poultry or fish; vegan diets further exclude dairy products and eggs. Vegetarian and vegan diets can vary widely, but the empirical evidence largely relates to the nutritional content and health effects of the average diet of well-educated vegetarians living in Western countries, together with some information on(More)
BACKGROUND Plasma concentrations of long-chain n-3 polyunsaturated fatty acids are lower in vegetarians and in vegans than in omnivores. No data are available on whether these concentrations differ between long- and short-term vegetarians and vegans. OBJECTIVES We compared plasma fatty acid composition in meat-eaters, vegetarians, and vegans and examined(More)
AIMS/HYPOTHESIS Fatty acid desaturases introduce double bonds into growing fatty acid chains. The key desaturases in humans are Delta5-desaturase (D5D), Delta6-desaturase (D6D) and stearoyl-CoA desaturase (SCD). Animal and human data implicate hepatic desaturase activities in insulin resistance, obesity and dyslipidaemia. However, the role of desaturase(More)
BACKGROUND Underreporting is a common problem in dietary surveys. Few studies have shown the implication of this when investigating diet-disease relations. OBJECTIVE We investigated how underreporting affects the associations between dietary factors and the metabolic syndrome. DESIGN Dietary intake measured with a 7-d food record, fasting insulin(More)
OBJECTIVE This study evaluates the association between abdominal obesity and the intake of dairy fat and calcium using information from dietary data and the relative content of the fatty acids 14:0, 15:0, and 17 : 0 in serum phospholipids (PL) and adipose tissue (AT), which are suggested biological markers for dairy fat intake. This study also explores how(More)
OBJECTIVE Proteins involved in cellular fatty acid (FA) uptake and metabolism may be of relevance in the context of disturbed FA metabolism associated with insulin resistance. Therefore this study investigated relationships between FA handling protein mRNA expression in adipose tissue, FA composition of adipose tissue and serum, and markers of insulin(More)
