Carotenoid and vitamin C intakes, assessed by FFQ, have been positively associated with plasma concentrations in different populations. However, the influence of BMI on these associations has not been explored in detail. We explored in a cross-sectional study the relation between dietary carotenoid and vitamin C intakes, using a 135-item FFQ, with their plasma concentrations by BMI categories in 252 men and 293 women, 65 years and older. For men and women combined, significant (P < 0.05… 

Tables from this paper

Correlates of the difference in plasma carotenoid concentrations between men and women.

The results suggest that physical characteristics as well as plasma lipids are associated with circulating carotenoid concentrations and that these variables should be taken into account when using plasmaCarotenoids as biomarkers for food intake in men and women.

Low intakes of vitamins C and A are associated with obesity in early adulthood.

The relationships between the intake of individual antioxidants as well as the dietary antioxidant quality score and obesity-related measures were evaluated to better understand the effect of dietary antioxidants on obesity.

The lower vitamin C plasma concentrations in elderly men compared with elderly women can partly be attributed to a volumetric dilution effect due to differences in fat-free mass.

The results indicate that a higher absolute FFM, and thus a higher distribution volume of vitamin C, contributes to lower vitamin C plasma concentrations in men than women.

Reduced plasma carotenoids in individuals suffering from metabolic diseases with disturbances in lipid metabolism: a systematic review and meta-analysis of observational studies

There were no significant summary measures for dietary outcomes, suggesting a physiological role of low serum carotenoids in the development of obesity and associated diseases.

Evaluation of dietary patterns among Norwegian postmenopausal women using plasma carotenoids as biomarkers

The healthy dietary pattern, the ‘Vegetarian’ pattern, is associated with a more favourable profile of the plasma carotenoids than the unhealthy dietary patterns, the‘Western’ and ‘Continental’ patterns.

Serum carotenoids are strongly associated with dermal carotenoids but not self-reported fruit and vegetable intake among overweight and obese women

Compared to self-reported FVI, dermal carotenoids measured by RRS is found to be a superior method to approximate serum carotanoids among overweight and obese women.

Biochemical Validation of a Self-Administered Food Frequency Questionnaire to Assess Diet Using Carotenoids and Vitamins E and D in Male Adolescents in Spain

The biochemical validity of a self-administered food frequency questionnaire (FFQ) in a sample of Spanish male adolescents using carotenoids and vitamin E and D data is assessed and may be an acceptable tool for dietary assessment among male adolescents in Spain.

Longitudinal association of measures of adiposity with serum antioxidant concentrations in postmenopausal women

The strongest observed associations between anthropometric variables and micronutrients were an inverse association ofWC with serum β-carotene and a positive association of WC with γ-tocopherol.

The correlations observed in this study indicate that the new carotenoid database provides valuable information on specific carOTenoid intake and may be useful in epidemiological studies that attempt to account for associations between fruit or vegetable intake and disease.

Investigation of diet and other factors with the plasma concentrations of carotenoids, retinol and tocopherols in a sample of 121 men and 186 women participating in two prospective investigations of dietary etiologies of chronic diseases found total vitamin E intake was positively associated with vitamin E supplements and inversely associated with gamma-tocopherol.

The diet-plasma relationships for carotenoids were examined in a group of 98 nonsmoking premenopausal women who participated in the cross-sectional phase of the National Cancer Institute-US Department of Agriculture diet study on alcohol-hormone metabolism, 1988-90, and data indicate that plasmaCarotenoid concentrations are reflective of dietary intake, but the magnitude of the correlation varies depending on the specific carOTenoid and on the dietary assessment tool.

Serum beta-carotene and alpha-tocopherol concentrations have different associations with diet, smoking, general adiposity, and central adiposity.

Human serum carotenoid concentrations are related to physiologic and lifestyle factors.

Correlations between serum and dietary carotenoids did not differ between smokers and nonsmokers, indicating that physiologic conditions that affect the absorption, storage, and utilization of Carotenoid intake may influence these associations.
