Grapefruit Juices Impair the Bioaccessibility of β-Carotene from Orange-Fleshed Sweet Potato but Not Its Intestinal Uptake by Caco-2 Cells

Abstract: Among various factors influencing β-carotene (Bc) bioavailability, information on interactions between carotenoids or other micronutrients such as flavonoids during a meal that contains different plant-derived foods is quite limited. Because orange-fleshed sweet potato (OFSP) is an important Bc-rich staple food, a source of vitamin A in developing countries, this study focused on the effect of citrus fruit juice carotenoids and flavonoids on Bc bioaccessibility from OFSP. In vitro digestion coupled with the Ca… Show more

“…The meals were also very similar in proximate composition (kcals, fat, carbohydrate, protein, P/S ratio). The concentration of naringenin, a polyphenol that is believed to influence the absorption of some medicines and supplements [21,22], was also similar.…”

“…Foi encontrado apenas uma publicação que avaliou a absorção dos carotenoides por cultivo de células Caco-2 em um cultivar de BDPL de Israel, cozido por 30 minutos (POULAERT et al, 2012). Os autores relataram 20% de absorção celular do trans-βC presente na fração aquosa.…”

“…Este resultado é condizente com os obtidos com os experimentos da presente pesquisa e os expostos na Figura 23, ou seja, absorção celular de 13% a 19%. O resultado discordante foi a absorção celular do 13-cis-βC reportada por Poulaert et al (2012) que foi menor (9,9%) do que a do trans-βC. Os mesmos autores também relataram interferência de compostos flavonoides que reduzem eficiência das células Caco-2 em absorverem os carotenoides.…”
