Mark:Do you have a reference to cite for the 80% figure? If I think I understand what you're saying then if (say) a serving of chocolate has 100 calories from fat the actual update/metabolization of those 100 calories is only 20?Also, found a citation specifically on anthocyanin intake affecting cholesterol:Source: American Journal of Clinical NutritionPublished online ahead of press, doi:10.3945/ajcn.2009.27814Anthocyanin supplementation improves serum LDL- and HDL-cholesterol concentrations associated with the inhibition of cholesteryl ester transfer protein in dyslipidemic subjectsAuthors: Y. Qin, M. Xia, J. Ma, Y. Hao, J. Liu, H. Mou, L. Cao, W. LingIncreased intakes of antioxidant anthocyanins may improve levels of HDL and LDL cholesterol, according to results of a new human study with 120 people.Consumption of berry-derived anthocyanin supplements resulted in a 13.7 per cent increase in levels of HDL cholesterol, and a 13.6 per cent reduction in levels LDL cholesterol, according to findings published online ahead of print in the American Journal of Clinical Nutrition.[snip ... ]In terms of the potential mechanism, the activity of a protein called plasma cholesteryl ester transfer protein (CETP) was studied. CETP works by collecting triglycerides from LDL and exchanging them for cholesteryl esters from HDL, and also the reverse.Supplements of the anthocyanins was found to reduce the activity of CETP by 6.3 per cent, while CETP activity fell by only 1.1 per cent in the placebo group, said the researchers.The change in HDL cholesterol was negatively correlated with the change in CETP activity, they wrote. The change in LDL cholesterol was positively correlated with the change in CETP mass, they added.Anthocyanin supplementation in humans improves LDL- and HDL-cholesterol concentrations and enhances the cellular cholesterol efflux to serum, wrote the researchers. These benefits may be due to the inhibition of CETP, they concluded.
