soluble fibreOne of two forms of dietary fibre—the other being insoluble fibre—which dissolves in water and slows gastric emptying, slows absorption of food, increases the stool bulk and reduces absorption of cholesterol, lowering LDL-cholesterol levels. A 5–10-g/day increase of soluble fibre in the diet translates into ±5% decrease in serum cholesterol, plasma LDL-cholesterol and apolipoprotein B, and lesser reductions of HDL-cholesterol and apolipoprotein AI.
