Insoluble cereal fiber (e.g., wheat bran) is associated with reduced cardiovascular disease risk in population studies, despite having no significant effect on fasting blood lipids.
Eat more whole grains and cereals for heart health. While this won't directly lower your cholesterol numbers like soluble fiber might, it is strongly linked to a lower risk of heart disease in the long run. This benefit may come from improved clotting factors or simply from the overall healthier lifestyle associated with high-fiber diets.
Ironically, it is the insoluble cereal fibre that has been demonstrated to relate negatively to cardiovascular disease and diabetes, despite an absence of effect on fasting lipids or postprandial glycaemia.
Why this rating
Based on cohort studies with potential confounders (lifestyle factors).

- Viscous soluble fibers (e.g., psyllium, oat beta-glucan) reduce LDL-cholesterol by 5-10% when consumed at doses of 5-10 g/day, primarily by reducing ileal bile acid absorption.Good
- Low Glycemic Index (GI) and Low Glycemic Load (GL) diets are associated with higher HDL-cholesterol, reduced triglycerides, and lower incidence of diabetes and cardiovascular disease.Good
- Resistant Starches (RS2, RS3) are lipid neutral, having no significant effect on serum lipids, while some nonabsorbable sugars (e.g., lactulose) may raise serum cholesterol.Moderate
