Abstract The objectives of this review were to investigate the status and characteristics of national grain consumption and dietary fiber intake among Chinese adults (aged ≥20 years) and to examine trends in consumption from 1982 to 2015. Data from 5 national surveys that collected dietary information using a household food weighing method and 24-hour dietary recall over 3 consecutive days were analyzed. In 2015, mean grain consumption was 281.1 g/per capita/d (rice 145.6 g, wheat flour 120.7 g, other grains 14.8 g). Total dietary fiber intake was 9.7 g/per capita/d, of which 3.8 g/per capita/d came from grains and accounted for nearly 40% of total dietary fiber intake for adults. The other major sources of dietary fiber were vegetables and fruits. The data indicates consumption of grains and dietary fiber in the Chinese population has been continuously declining since 1982 and the consumption of refined grains has increased. In order for the Chinese population to meet dietary recommendations for whole grain and dietary fiber intake, increasing the availability of more appealing whole grain products and public education are recommended.

Age and secular trends in dietary fiber intake of children were examined using the 24-hour dietary recall method. Dietary fiber intake of five cohorts of 1O-year-olds (n = 1254); two cohorts of 13-year-olds (n = 360); and children ages 10 (n = 767), 13 (n = 249), 15 (n = 108), and 17 (n = 89) years was examined from 1976 to 1988. Total dietary fiber intake remained unchanged from 1976 to 1988, even after adjusting for energy intake; averaging 12 or 5 g/1000 calories (kcal). Black children had higher fiber intakes per 1000 kcal than white children from ages 10 to 17 years. Consumption of vegetables and/or soups and breads and/or cereals accounted for 53% (10 years) to 70% (13 years) of the total fiber consumed. When children were stratified into quartiles based on fiber intake per 1000 kcal, the percent of energy from total fat and saturated fat was lower, and the percent of energy from carbohydrates was higher in children with higher fiber intakes per 1000 kcal. Additional studies are needed to document dietary fiber intakes of children and their impact on overall diet composition and cardiovascular risk factors.

Abstract Background The role of dietary fiber intake on risk of nasopharyngeal carcinoma (NPC) remains unclear. We examined the associations of dietary fiber intake on the risk of NPC adjusting for a comprehensive list of potential confounders. Methods Using data from a multicenter case-control study, we included 815 histologically confirmed NPC incident cases and 1502 controls in Hong Kong, China recruited in 2014–2017. Odds ratios (ORs) of NPC (cases vs controls) for dietary fiber intake from different sources at different life periods (age 13–18, age 19–30, and 10 years before recruitment) were evaluated using unconditional logistic regression, adjusting for sex, age, socioeconomic status, smoking and drinking status, occupational hazards, family history of cancer, salted fish, and total energy intake in Model 1, Epstein-Barr virus viral capsid antigen serological status in Model 2, and duration of sun exposure and circulating 25-hydroxyvitamin D in Model 3. Results Higher intake of total dietary fiber 10 years before recruitment was significantly associated with decreased NPC risk, with demonstrable dose-response relationship (P-values for trend = 0.001, 0.020 and 0.024 in Models 1–3, respectively). The adjusted ORs (95% CI) in the highest versus the lowest quartile were 0.51 (0.38–0.69) in Model 1, 0.48 (0.33–0.69) in Model 2, and 0.48 (0.33–0.70) in Model 3. However, the association was less clear after adjustment of other potential confounders (e.g. EBV) in the two younger periods (age of 13–18 and 19–30 years). Risks of NPC were significantly lower for dietary fiber intake from fresh vegetables and fruits and soybean products over all three periods, with dose-response relationships observed in all Models (P-values for trend for age 13–18, age 19–30 and 10 years before recruitment were, respectively, 0.002, 0.009 and 0.001 for Model1; 0.020, 0.031 and 0.003 for Model 2; and 0.022, 0.037 and 0.004 for Model 3). No clear association of NPC risk with dietary fiber intake from preserved vegetables, fruits and condiments was observed. Conclusion Our study has shown the protective role of dietary fiber from fresh food items in NPC risk, but no association for total dietary fiber intake was observed, probably because total intake also included intake of preserved food. Further studies with detailed dietary information and in prospective settings are needed to confirm this finding, and to explore the possible underlying biological mechanisms.

Abstract High dietary fiber intake has been associated with a lower risk of diabetes, but the association of dietary fiber with prediabetes is only speculative, especially in China, where the supportive data from prospective studies is lacking. This study aimed to examine the association between dietary fiber intake and risk of incident prediabetes among Chinese adults. We performed a prospective analysis in 18,085 participants of the TCLSIH cohort study who were free of diabetes, prediabetes, cancer, and cardiovascular disease at baseline. Dietary data were collected using a validated 100-item food frequency questionnaire. Prediabetes was defined based on the American Diabetes Association diagnostic criteria. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). During 63,175 person-years of follow-up, 4,139 cases of incident prediabetes occurred. The multivariable HRs (95% CIs) of prediabetes for the highest versus lowest quartiles were 0.85 (0.75, 0.98) (P for trend =0.02) for total dietary fiber, 0.84 (0.74, 0.95) (P for trend <0.01) for soluble fiber, and 1.05 (0.93, 1.19) (P for trend =0.38) for insoluble fiber. Fiber from fruits, but not from cereals, beans, and vegetables was inversely associated with prediabetes. Our results indicate that intakes of total dietary fiber, soluble fiber, and fiber derived from fruit sources were associated with a lower risk of prediabetes.

Background: Previous observational studies suggested a relationship between dietary fiber consumption and mental health, but the findings were conflicting. We evaluated the link between dietary fiber intake and prevalence of depression, anxiety, and psychological distress among a large population of Iranian adults.Methods: A cross-sectional study among 3,362 Iranian adults working in 50 health centers was done. Data of dietary intakes were collected through a validated semiquantitative dish-based 106-item food frequency questionnaire (FFQ). Anxiety, depression, and psychological distress were defined based on the Iranian validated version of Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire (GHQ).Results: After adjustment for potential confounders, participants in the top quartile of total dietary fiber intake had a 33% and 29% lower risk of anxiety and high psychological distress [odds ratio (OR): 0.67; 95% CI: 0.48, 0.95 and OR: 0.71; 95% CI: 0.53, 0.94, respectively] compared to the bottom quartile of intake. The highest total dietary fiber intake was also inversely related to a lower risk of depression in women (OR: 0.63; 95% CI: 0.45, 0.88) but not in men. Among overweight or obese participants, higher intake of dietary fiber was related to a decreased risk of high psychological distress (OR: 0.52; 95% CI: 0.34, 0.79). A high level of dietary fiber intake was related to a lower risk of anxiety in normal-weight individuals (OR: 0.50; 95% CI: 0.31, 0.80).Conclusion: Significant inverse associations between total dietary fiber intake with anxiety and high psychological distress were found in Iranian adults. More consumption of dietary fiber was also related to reduced odds of depression in women. More investigations with prospective nature are needed to affirm these findings.

Abstract Background Epidemiological evidence concerning dietary fiber on newly-diagnosed type 2 diabetes mellitus (T2DM) is sparse. Therefore, the purpose of this study was to investigate the relationship between dietary fiber intake and newly-diagnosed T2DM in a middle-aged Chinese population. Methods Using data from the Hangzhou Nutrition and Health Survey collected between June 2015 and December 2016, we investigated the associations between dietary patterns and the risk of chronic non- communicable diseases. Anthropometric measurements and samples collection for biochemical assays are conducted by the well-trained staff and nurse, respectively. Multivariable logistic regression analysis was used to analyze the effect of dietary fiber intake on the risk of newly-diagnosed T2DM in crude and adjusted models. Results Among 3250 participants, 182 (5.6%) people were identified as newly-diagnosed T2DM. Pearson correlation coefficients revealed a significant inverse association of total dietary fiber with BMI, SBP, DBP, HbA1c and LDL-C in all participants, participants with and without T2DM (P < 0.05). Compared with the study participants in the first quartile (Q1, the lowest consumption)of dietary fiber intake, participants in the fourth quartile (Q4) had a lower prevalence of newly-diagnosed T2DM(OR = 0.70; 95%CI:0.49-1.00; P < 0.05), after adjustment for potential confounders. Conclusions In this middle-aged Chinese population, higher intake of dietary fiber was significantly associated with lower risk of newly-diagnosed T2DM. However, our findings need to be confirmed in future large-scale prospective studies.

Abstract Objectives Greater maternal fructose intake is linked to greater offspring fat accrual, while dietary fiber intake is related to lower weight gain and a more favorable adipose tissue distribution. However, data are lacking investigating these relationships in the especially critical time of pregnancy and early infancy. We explored the relationships between maternal fructose and fiber intake on early offspring adipose tissue accrual. Methods This is a secondary analysis using data from a prenatal DHA supplementation trial (ADORE HD083292). At enrollment (12–16 wks), women completed the DHQ II food frequency questionnaire. ADORE mothers were invited to enroll in the GAINS infant follow up study (DK118220). Infant skinfolds were assessed two weeks and six months at three central sites (suprailiac, subscapular, flank) and three peripheral sites (biceps, triceps, thigh). Median splits were calculated for maternal fructose and total dietary fiber intake (&lt; 50th percentile, ≥50th percentile). An ANCOVA assessed the main effects of maternal fructose and fiber intake on infant fat accrual (central and peripheral). Results Data were available on n = 61 infants. For the change in infant central FM, a significant interaction (p = 0.034) was found between maternal fructose intake and dietary fiber intake. No effect of fiber was found in offspring exposed to low fructose intake. However, in offspring exposed to high fructose intake during pregnancy, exposure to high maternal dietary fiber intake was related to lower central FM accrual (high fiber intake: 4.2 mm vs. low fiber intake 6.9 mm; p = 0.016). No significant main effects or interaction was detected for the change in peripheral FM. Conclusions In offspring exposed to greater maternal fructose consumption during pregnancy, greater maternal intake of dietary fiber was related to lower early offspring central fat accretion. Interventions targeting to decrease maternal fructose consumption and increase maternal dietary fiber intake may positively impact offspring fat accretion.
