Bioavailability of Non-Provitamin A Carotenoids
The role of carotenoids in human nutrition has gained increased interest, especially due to their associated health-beneficial effects for a number of chronic diseases, including certain types of cancer and cardiovascular disease. Whereas data is available on the intake and presence of carotenoids in foods, limited information exists on factors influencing their bioavailability, especially for ...
متن کاملBioavailability of carotenoids in human subjects.
There is growing need for accurate information regarding the bioavailability of carotenoids, both with respect to carotenoids per se and to the vitamin A value of provitamin A carotenoids in foods or supplement preparations. Little quantitative information is currently available, owing primarily to the lack of adequate methods to assess carotenoid bioavailability. Methods applied to xenobiotic ...
متن کاملBioavailability of Dietary Carotenoids: Intestinal Absorption and Metabolism
Various carotenoids with diverse structures are present in foods and have been reported to have beneficial effects on human health. Owing to their hydrophobicity, however, poor solubilization in the aqueous milieu of the digestive tract restricts their intestinal absorption. Fats and oils were found to increase the solubilization of carotenoids into mixed-micelles, which would therefore enhance...
متن کاملBioavailability Studies of Carotenoids Using Human Exfoliated Colonic Epithelial Cells*
As described before, anumber offactors affect the bioavailability ofvitamin A and provitamin A carotenoids such as their conversion to vitamin A, rate ofabsorption, transport, chemical nature ofthe provitamin A, and also the fat content in the diet. The type of food matrix in which carotenoids are located is a major factor affecting the bioavailability ofprovitamin A carotenoids; bioavailabilit...
متن کاملDietary factors that affect the bioavailability of carotenoids.
Carotenoids are thought to contribute to the beneficial effects of increased vegetable consumption. Various dietary factors have an effect on the bioavailability of carotenoids. The type of food matrix in which carotenoids are located is a major factor. The bioavailability of beta-carotene from vegetables in particular has been shown to be low (14% from mixed vegetables) compared with that of p...
