It has been known for decades that fiber is beneficial for the digestive tract. Yet, every so often a study declaring that to be unfounded would pop up and ignite some controversy. Today, the evidence could be said to be overwhelming that fiber in the diet is vital, not only for health, but for total well-being.
A systematic review and meta-analysis published in The Lancet early this year suggested a causal relationship between a high-fiber diet and reduced incidence of non-communicable disease. That is, consuming greater daily amounts of dietary fiber leads to reduced body weight, total cholesterol, and systolic blood pressure.
