Fiber is a food source for the good bacteria in the digestive tract. The good bacteria feeds on the fiber and produces the short-chain fatty-acid called butyrate. Butyrate is the fuel source that feeds the cells that line and protect the colon. The American standard diet lake of Fiber consider increasing your fiber intake to prevent diseases.Studies show that the natural fiber in food is protective against bowel disease, colon cancer, diabetes, and heart disease, and fiber isolates or extracts is not.[1] The rule of thumb is the foods you consume should have a carbohydrate to fiber ratio that is 5 to 1. A ratio of 5 to 1 or less optimally supports health and reduces the risk of chronic diseases.

Example One

The granola bar contained 27g of carbohydrates and 2g of fiber. Divide 27 by 2 and you end up with around 13 which is more than 5, so it failed the test.

Example Two

Example

This bar contained 18g of carbohydrates and 6g of fiber. Divide 18 by 6 and you end up with around 3 which is less than 5, so it pass the test.
