Increasing total dietary fibre intake by 7 g/day is associated with a 9% lower risk of cardiovascular disease and coronary heart disease.
To lower your risk of heart disease, aim to add roughly 7 grams of fibre to your daily diet. This is roughly equivalent to one extra serving of whole grains, fruit, or vegetables. Start by swapping refined grains for whole grains or adding a piece of fruit to your snacks. Consistency matters more than perfection.
With each increase of 7 g/day in intake of total fibre, relative risks were 0.91 (95% confidence interval 0.88 to 0.94) and 0.91 (0.87 to 0.94) for cardiovascular disease and coronary heart disease, respectively.
Why this rating
High-quality evidence from 19 prospective observational studies with dose-response analysis, though observational nature limits causal inference compared to RCTs.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
