Absorption of fat-soluble vitamins and sterols
نویسنده
چکیده
The molecular structure of the four fat-soluble vitamins and of cholesterol, the major intestinal sterol in man, are shown in Figure 1. In spite of the obvious dissimilarities that exist between these compounds they possess one common feature, namely, they are all nonpolar lipids with extremely low solubilities in aqueous media. Because of this, it is convenient to consider them together when examining the mechanisms involved in their absorption, although the individual differences that exist will also be discussed.

Consumption of a dietary portfolio of cholesterol lowering foods improves blood lipids without affecting concentrations of fat soluble compounds
BACKGROUND Consumption of a cholesterol lowering dietary portfolio including plant sterols (PS), viscous fibre, soy proteins and nuts for 6 months improves blood lipid profile. Plant sterols reduce blood cholesterol by inhibiting intestinal cholesterol absorption and concerns have been raised whether PS consumption reduces fat soluble vitamin absorption. OBJECTIVE The objective was to determi...

Plasma fat-soluble vitamin and carotenoid concentrations after plant sterol and plant stanol consumption: a meta-analysis of randomized controlled trials
PURPOSE Plant sterols and stanols interfere with intestinal cholesterol absorption, and it has been questioned whether absorption and plasma concentrations of fat-soluble vitamins and carotenoids are also affected. We conducted a meta-analysis to assess the effects of plant sterol and stanol consumption on plasma fat-soluble vitamin and carotenoid concentrations. METHODS Forty-one randomized ...

The aim of the present study was to determine and compare the seasonal changes in the proximate composition, fatty acids profile and fat soluble vitamins content in spring and autumn goby (Neogobius melanostomus) caught from the Bulgarian Black Sea waters. The proximate composition (moisture, protein and total lipid) has been determined according to AOAC (1990). Analysis of fatty acid methyl e...
