Increasing daily dietary fibre intake to 35 grams (or by 15 grams from baseline) significantly reduces all-cause mortality, improves glycaemic control (HbA1c), and lowers cardiometabolic risk factors in adults with prediabetes or diabetes.
To manage diabetes and reduce mortality risk, aim to consume 35 grams of dietary fibre daily, or add 15 grams to your current intake. Focus on whole grains and fibre-rich foods without needing to restrict other macronutrients. This change is associated with fewer deaths and better blood sugar control.
GoodSupportsHIGH confidence
Based on these findings, increasing daily fibre intake by 15 g or to 35 g might be a reasonable target that would be expected to reduce risk of premature mortality in adults with diabetes.
Why this rating
GRADE protocols rated evidence as moderate to high, though trial heterogeneity was high.
