Plasma carotenoids, tocopherol and retinol research in the age of 35-74 years in six European countries. Nutrient status may change with age. We analyzed plasma carotenoids, α- / γ-tocopherol and retinol, and compared them with age, demographic characteristics, and eating habits (assessed by a short food frequency questionnaire) in a cross-sectional study of 2118 men and women (age-stratified 35 -74 years) of the population in six European countries. Older age was associated with lower lycopene and α- / β-carotene and higher β-cryptoxanthin, lutein, zeaxanthin, α- / γ-tocopherol and retinol levels. Significant correlation with age were observed for lycopene, α-tocopherol, α-carotene and β-cryptoxanthin. Age was inversely associated with lycopene and this...
