Nutrition & Metabolism, 2023 AbstractIn the last century, vitamin A was identified that included the nutritional relevant vitamin A1 / provitamin A1, as well as the vitamin A2 pathway concept. Globally, nutritional guidelines have focused on vitamin A1 with simplified recommendations and calculations based solely on vitamin A.

Antioxidant activity of vitamin C, E, and provitamin A
Grasas y Aceites, 1993 As a continuation of the study of natural antioxidants, this paper includes vitamin C (ascorbic acid), vitamin E (tocopherols and tocotrienols), and provitamin A (β-carotene, lutein, zeaxanthin, isozeaxanthin, lycopene, astaxanthin and cantaxanthin) and, as well as those derivatives of these which have been described as antioxidants, either used as ...

Provitamin A and Vitamin C in Salted Nozawa-na
Eiyo To Shokuryo, 1963 The common scarcity of vegetables, especially of leafy ones in winter season makes it important to investigate the convenient sources of vitamin A and C during this season. The growing of the leafy vegetable Nozawa-na (a variety of Brassica Rapa LINN.) is practiced in the central mountaineous region of Japan in autumn, and then they are salted down for

Overlapping Vitamin A Interventions with Provitamin A Carotenoids and Preformed Vitamin A Cause Excessive Liver Retinol Stores in Male Mongolian Gerbils [PDF]
The Journal of Nutrition, 2020 Vitamin A (VA) deficiency is a public health problem in some countries. Fortification, supplementation, and increased provitamin A consumption through biofortification are efficacious, but monitoring is needed due to risk of excessive VA intake when interventions overlap.Two studies in 28-36-d-old male Mongolian gerbils simulated exposure to multiple ...

Vitamin A bioefficacy of traditional and provitamin A‐biofortified banana
The FASEB Journal, 2011 The provitamin A biofortification of banana could provide a sustainable and cost effective method to ameliorate vitamin A deficiency in many tropical countries where banana is a staple food. However, matrix effects in banana may limit the absorption of vitamins, which could render biofortification efforts ineffective.

Mechanisms involved in the intestinal absorption of dietary vitamin A and provitamin A carotenoids [PDF]
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2012 Vitamin A is an essential nutrient for humans and is converted to the visual chromophore, 11-cis-retinal, and to the hormone, retinoic acid. Vitamin A in animal-derived foods is found as long chain acyl esters of retinol and these are digested to free fatty acids and retinol before uptake by the intestinal mucosal cell. The retinol is then reesterified

Vitamin C, Provitamin A Carotenoids, and Other Carotenoids in High-Pressurized Orange Juice during Refrigerated Storage [PDF]
Journal of Agricultural and Food Chemistry, 2002 Vitamin C, provitamin A carotenoids, and other carotenoids were measured in freshly squeezed juices from oranges (Citrus sinensis L. var. Valencia late) that were subjected to high-pressure (HP) treatment. Also, the stability of these compounds was studied during refrigerated storage at 4 degrees C.

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security
Journal of the Science of Food and Agriculture, EarlyView.Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Several commercial berries have been examined for anthocyanin composition, bioaccessibility, and bioactive effects, while Brazilian berries remain underexplored. This study aimed to access the effect of in vitro gastrointestinal digestion on anthocyanin bioaccessibility, stability, and antioxidant potential in black pitanga (Eugenia
