Adopting CODEX-aligned dietary fiber definitions that include digestion-resistant oligomers (DP 3-9) and added fibers is a necessary strategy to bridge the global 'fiber gap' and improve population health.
To improve your health, focus on getting enough dietary fiber from all sources, not just whole foods. Look for foods fortified with added fibers (like resistant oligomers or resistant starch) as these are now recognized as beneficial. Aim for the recommended daily intake (e.g., 25-38g depending on gender and region) by combining whole grains, legumes, fruits, and vegetables with fiber-fortified options to bridge the gap between what you eat and what your body needs.
The new CODEX definition enfranchising added fibers along with fibers traditionally found in food underscores the need for all types of fibers... as part of a strategy to address the inadequate intake of DF.
Why this rating
The paper is a comprehensive review citing numerous epidemiological and intervention studies, though it is not a primary clinical trial itself.
