More fiber in the diet is associated with less death

A new article in the Archives of Internal Medicine shows a relationship between high fiber diets and lower death rates.

While association does not prove causation, it does provide food for thought (pun intended).

  1. From the accompanying editorial:
    “The most striking finding of Park and coauthors’ study is an inverse association between fiber intake and death from infectious and respiratory diseases. This was the strongest association observed. Park and colleagues suggest that the benefit of dietary fiber is attributable to antioxidant and anti-inflammatory properties of whole grain components, which are correlated with cereal fiber. Whole grains have a high antioxidant potential and contain numerous minerals, such as selenium and zinc, which are cofactors for antioxidant enzyme systems, and radical scavengers, such as polyphenols (eg, lignans, alkylresorcinols).9 These compounds may protect tissues from oxidative damage, which is characteristic of chronic inflammation and is common in chronic diseases such as cardiovascular disease, diabetes, rheumatoid arthritis, and Crohn disease.”

  2. “It is also important to distinguish between the effects of dietary fiber and those of whole grains. While fiber is clearly a component of whole grains, the reverse is not true. Fiber isolates probably do not provide the same benefits as intact, whole grains. The appropriate public health recommendation should therefore be to increase consumption of whole grains at the expense of refined grains. Substituting whole grains for refined grains would provide benefits not only from fiber but also from other unique health-promoting components of whole grains.”
