Eating Fiber Increases Life Span

High Fiber Diets have been linked with lower chances of heart disease, infectious and respiratory illness, cancer, and an overall longer life span in this study. People with high fiber diets were 22% less likely to die from any cause compared to those who had lower amounts. Confounding variables such as weight, education level, smoking and health status were taken into account. They suggest about 38 grams of fiber a day for men and 25 grams for women. 


I knew fiber is a necessary nutrient we need daily , but I did not think it would have such a large impact on our health that this study suggests. It even says that fiber may have strong immune benefits. More insight into how the study was preformed is found at http://www.cbs6albany.com/news/fiber-1282873-grams-study.html showing it was a prospective study with  31,000 participents. Although these results strongly show correlation, I am sure more evidence is still being complied to help support or verify causation.
