Bioavailability of b-carotene (bC) from purple carrots is the same as typical orange carrots while high-bC carrots increase bC stores in Mongolian gerbils (Meriones unguiculatus)

Vitamin A (VA) deficiency is a worldwide public health problem. Biofortifying existing sources of b-carotene (bC) and increasing dietary bC could help combat the issue. Two studies were performed to investigate the relative bC bioavailability of a bC supplement to purple, high-bC orange, and typical orange carrots using Mongolian gerbils (Meriones unguiculatus). In study 1, which used a traditi...

Orange skin tone from too many carrots?

The old adage, ?you are what you eat? couldn?t be more true when it comes to carrots. To answer your question: yes, you can take on an orange-ish hue if you eat too many carrots. This phenomenon ? known in medical circles as ?carotenemia?? fortunately has no known risks to a person?s health. Carrots have this colorful effect because they are chock-full of betacarotene, which is a pigment found ...

Carotene Hydroxylase Activity Determines the Levels of Both α-Carotene and Total Carotenoids in Orange Carrots.

The typically intense carotenoid accumulation in cultivated orange-rooted carrots (Daucus carota) is determined by a high protein abundance of the rate-limiting enzyme for carotenoid biosynthesis, phytoene synthase (PSY), as compared with white-rooted cultivars. However, in contrast to other carotenoid accumulating systems, orange carrots are characterized by unusually high levels of α-carotene...

Nutrient Requirements Twice the Amount of -Carotene Isolated from Carrots Is as Effective as -Carotene in Maintaining the Vitamin A Status of Mongolian Gerbils

The vitamin A (VA) value of carotenoids from fruits and vegetables is affected by many factors. This study determined the VA value of -carotene isolated from carrots compared with -carotene and retinyl acetate supplements fed to Mongolian gerbils (Meriones unguiculatus). Gerbils (n 38) were fed a VA-free diet for 4 wk. At baseline, 6 gerbils were killed to determine liver VA. Gerbils were divid...

Bioconversion Efficiency of β-Carotene from Mango Fruit and Carrots in Vitamin A

Problem statement: Bioconversion efficiency of β-Carotene (BC) in vitamin A is strongly influenced by food matrix. This efficiency has been determined mainly in typical BC sources like carrots. BC content in mango fruit is considerably high however; the bioconversion efficiency of BC from fresh mango in vitamin A has not been determined nor compared with those of typical BC sources. Approach: V...
