The present invention relates to a composition comprising
Rhodospirillum rubrum cells for use in a method for inhibiting the uptake of
cholesterol from the intestine in a human subject, such that the
plasma LDL-
cholesterol level in said human subject is lowered and concentrations of
blood proteins relating to
kidney function,
liver function and / or heart function are essentially unaltered. In addition, the invention relates to a non-therapeutic method of lowering
plasma LDL-
cholesterol level in a subject, the method comprising administering to the subject a composition comprising
Rhodospirillum rubrum cells, wherein lowering of the
plasma LDL-cholesterol level is the inhibition of the uptake of cholesterol from the intestine in said human subject. Furthermore, the invention relates to a food product, a feed product, a food stuff and a
food supplement comprising
Rhodospirillum rubrum cells and having plasma LDL-cholesterol level lowering properties relating to intestinal cholesterol uptake inhibitory properties.
