The vast majority of adults in the United States are not meeting their daily fiber recommendations. The average daily intake of dietary fiber for adults in the United States is only 15 grams, which falls far short of the recommended intake of 25-38 grams per day. Low dietary fiber intake is associated with a range of adverse health outcomes, including increased risk of heart disease, diabetes, and certain types of cancer.
A systematic review and meta-analysis of studies on dietary fiber intake and mortality found that consuming at least 25 grams of dietary fiber per day was associated with a lower risk of death from cardiovascular disease, cancer, and all causes, but that most people worldwide consume less than 20 grams per day. In populations with low fiber intake, increasing fiber intake to at least 25-29 grams per day could prevent premature deaths and disability from non-communicable diseases.
In Australia, dietary fibre intakes are low and continue to decline, with only 30% of adults meeting the recommended daily intake of 25g per day. Low fibre intakes have been linked to increased risk of chronic disease, including cardiovascular disease, type 2 diabetes and some cancers.
In the UK, the mean dietary fibre intake is about 14 g/day, less than half the recommended intake of 30 g/day. Low intakes of fibre are associated with an increased risk of chronic diseases such as heart disease, diabetes and bowel cancer.
A study conducted in Malaysia found that the mean fiber intake among adults was only 13.2 grams per day, which is well below the recommended intake of 25-30 grams per day for adults. The study also found that low fiber intake was associated with a higher risk of chronic diseases such as diabetes and heart disease.
A cross-sectional study conducted in Singapore found that the prevalence of inadequate fiber intake among adults was 94.8%, with an average intake of only 16.2 grams per day. The study also found that low fiber intake was associated with a higher risk of obesity and metabolic syndrome.
A study conducted in India found that the mean fiber intake among adults was only 14.2 grams per day, which is lower than the recommended intake of 20-35 grams per day. The study also found that low fiber intake was associated with a higher risk of cardiovascular disease and type 2 diabetes.
