Abstract:
... Retinol Binding Protein (RBP) is responsible for the transport of serum retinol (SR) to target tissue in the body. Since RBP is relatively easy and cheap to measure, it is widely used in national Micronutrient Surveys (MNS) as a proxy for SR to determine vitamin A status. By regressing RBP concentration against SR concentration measured in a subset of the survey population, one can define a popula ...

Abstract:
... Producing, reporting, and interpreting vitamin A statistics present multiple challenges largely attributable to the systems of equivalence used to convert pro-vitamin A carotenoids into retinol equivalents, and to the criteria used by institutions to set recommendations. This study describes the information on total vitamin A, retinol and pro-vitamin A carotenoids available in 89 food composition ...

Abstract:
... In this study, cholesterol (CH), β-sitosterol (SI), and stigmasterol (ST) were explored to improve the stability of retinol in the liposome bilayer. Retinol was incorporated into liposomes composed of soybean-derived L-α-phosphatidylcholine (PC) and 10% sterol (w/w), which were prepared as multilamellar vesicles. Under all conditions, the efficiency of retinol incorporation into liposomes was high ...

Abstract:
... Global food trade enables the flow of dietary nutrients between countries. However, little is known about whether trade improves nutrient supply of countries most in need. Using detailed production and bilateral trade data, we found that despite strongly connected global nutrient networks, trade did not substantively improve the nutrient adequacy of most low/lower-middle income countries (~40% of ...

Abstract:
... Vitamin A is necessary for an adequate immune response to infections. Infection also alters vitamin A biomarkers, which interferes with assessment of vitamin A deficiency and thus impairs clinical management. Here we apply multiple strategies to adjust vitamin A biomarkers for inflammation during acute infection and evaluate associations between adjusted vitamin A status and immunologic response m ...

Abstract:
... Vitamin A is essential for vision, human health, growth, immune function, and reproduction. Its deficiency leads to anemia, xerophthalmia, and growth reduction in children. Foods enriched with naturally occurring carotenes have the potential, in this regard, and orange‐fleshed sweet potato (OFSP) stands out tall as it is rich in β‐carotene (βC), a provitamin A carotenoid. In view of developing OFS ...

However, humans usually die from vitamin A deficiency before cancers have time to develop. A recent long-term cohort study found that high dietary vitamin A reduced the risk of cutaneous squamous cell carcinoma (cSCC). cSCC is a form of nonme ...
