Long-term effect of bran ingestion on lipid metabolism in healthy man.

The long-term effect of the addition of 20 g wheat bran to the diet is studied over 7 weeks in 4 healthy subjects. No change is found in plasma cholesterol and triacylglycerol. In this experimental design, we find no modification in the plasma levels of the various lipoproteins, except for VLDL cholesterol, which remains significantly lower after 7 weeks of wheat bran ingestion.
