BMM,
Have you tried any of the cholesterol reducing spreads ? I know of two freely available in the UK and I use them just as part of my normal diet.
They have shown with regular consumption, a reduction of 10-15% in cholesterol. One assumes that this is the 'bad' cholesterol. Basically they contain plant sterols (?) which prevent the body processing and absorbing cholesterol so it passes through as it were.
Cheers
