Carotenoids are one of the major food micronutrients in human diets and the overall objective of this review is to re-examine the role of carotenoids in human nutrition. We have emphasized the attention on the following carotenoids present in food and human tissues: beta-carotene, beta-cryptoxanthin, alpha-carotene, lycopene, lutein and zeaxanthin; we have(More)
A high-performance liquid chromatographic (HPLC) separation method with photo-diode array (PDA) and mass spectrometric (MS) detection was developed to determine and quantify flavonols, flavones, and flavanones in fruits, vegetables and beverages. The compounds were analysed as aglycones, obtained after acid hydrolysis of freeze-dried food material.(More)
Epidemiological studies have suggested an association between consumption of red wine and other polyphenolic compounds and prevention of cardiovascular diseases. In the present study, Watanabe heritable hyperlipidemic (WHHL) rabbits were used to investigate the effects of polyphenols in a red grape skin and seed extract (GSE) on the development of(More)
Seven men and seven women participated in a randomized crossover trial to study the effect of intake of parsley (Petroselinum crispum), containing high levels of the flavone apigenin, on the urinary excretion of flavones and on biomarkers for oxidative stress. The subjects received a strictly controlled diet low in flavones and other naturally occurring(More)
BACKGROUND Epidemiologic studies suggest that foods rich in flavonoids might reduce the risk of cardiovascular disease. OBJECTIVE Our objective was to investigate the effect of intake of flavonoid-containing black currant and apple juice on urinary excretion of quercetin and on markers of oxidative status. DESIGN This was a crossover study with 3 doses(More)
Genetically modified plants must be approved before release in the European Union, and the approval is generally based upon a comparison of various characteristics between the transgenic plant and a conventional counterpart. As a case study, focusing on safety assessment of genetically modified plants, we here report the development and characterisation of(More)
Anthocyanin-rich beverages have shown beneficial effects on coronary heart disease in epidemiological and intervention studies. In the present study, we investigated the effect of black currant anthocyanins on atherosclerosis. Watanabe Heritable Hyperlipidemic rabbits (n = 61) were fed either a purified anthocyanin fraction from black currants, a black(More)
To estimate the contents of flavonoids in the Danish diet, we have used a high performance liquid chromatographic method for the analysis of fruits, vegetables and beverages. The flavonoid contents were quantified, and the observations were verified by mass spectrometry. The investigation is not completed, but we are able to give an preliminary estimate of(More)
OBJECTIVE To measure the iodine content in bread and household salt in Denmark after mandatory iodine fortification was introduced and to estimate the increase in iodine intake due to the fortification. DESIGN The iodine content in rye breads, wheat breads and salt samples was assessed. The increase in iodine intake from fortification of bread and the(More)
The demand for organic food products is steadily increasing partly due to the expected health benefits of organic food consumption. Polyphenols, such as flavonoids and phenolic acids, are a group of secondary plant metabolites with presumably beneficial health effects, and contents in plants are affected by, for example, plant nutrient availability,(More)
