Participants increased their average dietary fiber intake after MI, and the greater the increase, the lower was the risk of subsequent all cause and cardiovascular mortality.
Separately, N-acetylglycine was significantly associated with average dietary fiber intake, after adjusting for sex, age, and BMI (β ± SE, 2.1 ± 1.0, P = 0.03).
We considered both simple updated and cumulative average of fiber intake as described elsewhere 26 and presented simple updated analyses because of similar results.
Estimates from the food frequency questionnaire adequately reflect long term average dietary fiber intake based on several weeks of formal diet records (r=0.68 for dietary fiber, r=0.79 for cold breakfast cereal, the major source of fiber in these two populations).
The average daily fiber intake of Americans is approximately 12 to 15 grams per day.
The EFSA recommends average dietary fiber intakes of 10 to 20 g per day for young children (<10 to 12 years), 15 to 30 g per day for adolescents, and 16 to 29 g per day for adults [ 26].
Participants on average increased their fiber intake from the before to after MI period (table 3).
The mean daily fiber intake was 14 ± 8 g.
Results for the LP one repetition maximum, SPPB, 400-m, total lean and fat mass, BMI, average dietary protein and fiber intake in older adults (mean age, 77.7 ± 3.9 years; N = 73, 43 women, 30 men) from the randomized, double-blind, controlled study of (Chale et al., 2012) were used.
Fiber intake from other foods did not differ between groups and averaged 0.5 g/day.
