Abstract
This study evaluated reported dietary fiber and mineral intakes of 45 healthy adults, 60 years and over, using two sets of three-day dietary food records. The average age of the participants was 73 years, with an age range of 60 to 87 years. Mean reported dietary fiber intake was 18.3 g per day. Percentage of dietary fiber from different food sources was; breads and cereals 33%, vegetables 22%, fruits 21%, beans and legumes 7%, nuts and seeds 3%, combination foods 7% and others 7%. Significant positive correlations were observed between dietary fiber intake and copper, magnesium, selenium, potassium, iron and zinc intakes. Those participants with dietary fiber intakes of 20 g/day or more had significantly higher intakes of copper, magnesium, selenium, potassium and iron compared to those who had dietary fiber intakes less than 20 g/day, although mean kilocalorie intakes were not significantly different. Thus, increasing grain products, vegetables and fruits to increase dietary fiber intake, also may improve the mineral intakes of older adults.
