Consumption of specific soluble dietary fibers (psyllium, oat beta-glucan) significantly reduces serum apolipoprotein B (ApoB) levels, whereas other soluble fibers (konjac glucomannan) may have no significant effect.

To lower your ApoB and heart disease risk, prioritize specific soluble fibers like psyllium husk or oat beta-glucan. General fiber intake is important, but the source matters: studies show psyllium significantly lowers ApoB, while other fibers like konjac may not have the same effect. Aim for 8-15 grams of these specific fibers daily, ideally alongside a balanced diet.
