Fat and dietary fiber intake and colon cancer mortality: A chronological comparison between Japan and the United States

Dietary fiber is one of the most essential food component, mainly used to maintain health andbalance of digestive system. Dietary fiber plays an important role in health, especially in reducingblood cholesterol, improving glucose absorbtion for diabetic patients, preventing colon cancer,and reducing weight. Several studies showed that seaweed is a potential source of dietary fiberwith more advantages compare to that of land-based crops. Contrary to its production, seaweedconsumption in Indonesia is relatively low. To date, dietary fiber intake for the majority of Indonesiansis fulfiled from land-based crops.

Socioeconomic And Demographic Factors

Consumers in the United States fall short of meeting the recommended guideline for dietary fiber intake. Using a quarterly panel of households from Nielsen for the years 2004 through 2014, we employ a Heckman two-step approach to estimate nine panel regressions concerning per person fiber intakes derived from various food categories to uncover the importance of prices as well as socioeconomic and demographic factors. Prices play a prominent role in the per person intake of dietary fiber derived from the respective food products considered. Households below poverty thresholds had lower intakes of fiber relative to households above poverty thresholds. Ethnicity, race, age of the household head, region, and the presence of children also had significant effects on dietary fiber derived from the respective food categories. A proposed 20 percent subsidy applied to fruits and vegetables would increase per person intake of fiber by 9.4 percent. Therefore, if one were to consider meeting the dietary fiber requirement only through the provision of a subsidy, a large subsidy applied to fruits and vegetables would be required. Therefore, given the complex nature of the various factors affecting the intake of dietary fiber, the feasibility of using subsidies alone to increase the intake of dietary fiber is called into question.

e15080 Background: Epidemiological studies have suggested that intake of dietary fiber is associated with decreased risk of colon cancer, however, these findings are inconsistent in that dietary fiber intake is differentially associated with risks of proximal colon and distal colon cancers. To address this, we conducted a systematic review and meta-analysis. Methods: Pubmed database were searched to identify relevant cohort studies up to December 2016 to examine the association between dietary fiber and risks of proximal colon and distal colon cancers, respectively. A random-effects model was used to compute summary risk estimates. Results: 11 prospective cohort studies were identified and included in the analysis. We observed that the risk of proximal colon cancer was 14% lower among the highest dietary fiber intake compared with the lowest intake (RR = 0.86, 95% confidence interval [CI] = 0.78 to 0.95). A similar result was also found for distal colon cancer (RR = 0.79, 95% CI = 0.71 to 0.87). Conclusions: In current analysis, we show that dietary fiber intake is associated inversely with risks of both proximal and distal colon cancers.
