1st December 2014: Dietary fibre, particularly cereal fibre, has been linked to lower total mortality, in a number of recently published scientific studies and reviews.
These research findings are consistent with previous cohort studiesand continue to build evidence that benefits of fibre are dose dependent – the more fibre consumed, the greater the disease protection.
Breakfast cereal is one of the main sources of fibre in Australian diets contributing 10.6% of daily fibre intakes.1
20g Of Fibre A Day Boosts Longevity
New data from the renowned PREDIMED Study – the longest observational study of the Mediterranean diet – has linked 20g of fibre a day to a significant reduction in all cause mortality among older people at risk of heart disease.2
The findings, published in the American Journal of Clinical Nutrition (Sept 2014), showed participants who consumed a high fibre diet (35g/day) had a 37% lower risk of all cause mortality and a 54% lower risk of death from cardiovascular disease (CVD) compared to those eating the least fibre (17g/day).2
Researchers also noted significant reductions in mortality among people consuming 20g of fibre a day or more.3
High Fibre Diet Reduces Death Risk By 23%
A diet high in fibre, particularly cereal fibre, has been linked to a 23% reduction in total mortality.3
The recent meta-analysis, published in the American Journal of Epidemiology (Aug 2014), reviewed seven studies involving more than 900,000 participants. The US researchers concluded people with a high fibre diet (27g/day) had a 23% lower risk of total mortality compared to those with relatively low fibre intakes (15g/day). 4
The more fibre consumed the greater the benefit, with each additional 10g of fibre a day, lowering the risk of death from all causes by 11%.4
Researchers identified cereal fibre as providing the greatest protection followed by fibre from vegetables.3
High Fibre Diet Boost Longevity Of Heart Attack Survivors
Heart attack survivors who increase their fibre intakes could live longer, according to researchers at the Harvard School of Public Health and published in the British Medical Journal (April 2014).4
The study analysed the Nurses’ Health Study and the Health Professional Follow-up Study which included data of more than 4 000 heart attack survivors, and found those who ate the most fibre (27g/day) after their heart attack had a 25% lower chance of dying following their heart attack, compared with those who ate the least fibre (13g/day).4
Like in Australia, breakfast cereal was the main source of fibre with the authors stating “overall, the benefits for increased fibre intake were strongest for fibre from cereal and grain sources”. 4Once again the protection was dose dependant with every 10g per day increase in fibre associated with a 15% reduced risk of dying during the years following the heart attack.4
