    Prospective study finds that gluten free diets for some may limit healthy whole grains, which may increase CVD.  This increase was 75 cases per 100 000 persons.  However, the study did find that it appears that an elimination of the whole grains likely is the culprit.  An elimination of refined processed grains and not whole grains is beneficial.  A gluten free diet is not and should not be a dietary fad.  If testing reveals gluten free nutrition is required, only then should this be pursued with the additions of certain, whole-grain foods.

    small study finds diet rich in whole grains compared to refined grains improves gut bacteria balance and immune system.  Maybe the key to optimal gut health is the diet?

  • DF are highly complex substances that can be described as any nondigestible carbohydrates and lignins not degraded in the upper gut
  • Commonly, DF are classified according to their solubility in water, even though grading according to viscosity, gel-forming capabilities, or fermentation rate by the gut microbiota might be physiologically more relevant
  • Main sources of soluble DF are fruits and vegetables
  • ...8 more annotations...
  • n increased intake of total DF was inversely associated with markers of insulin resistance in several studies
  • consumption of insoluble DF increased whole body glucose disposal independent of changes in body weight in both short-term and more prolonged studies
  • Short-chain fatty acids (SCFA) such as acetate, propionate, and butyrate are produced by bacterial fermentation of indigestible DF polysaccharides in the colon
  • increased production of SCFA is assumed to be beneficial by reducing hepatic glucose output and improving lipid homeostasis
  • a high DF diet (oligofructose) reduced gram-negative bacterial content and body weight, whereas a high fat diet increased the proportion of a gram-negative bacterial lipopolysaccharides (LPS) containing microbiota in humans
  • Prospective cohort studies indicate that diets high in insoluble cereal DF and whole grains might reduce diabetes risk
  • soluble DF (i.e., pectin, inulin, and β-glucans)
  • cereal DF (i.e., cellulose and hemicelluloses)

dietary fiber

  • decreased risk of coronary heart disease with dietary fiber consumption
  • Good sources of dietary fiber include whole grains, legumes, vegetables, nuts and seeds, and fruits
  • most experts recommend that fiber should be obtained through the consumption of foods, because this form allows consumption of many micronutrients and bioactive compounds contained in high-fiber foods, which provide their own nutritional benefits.
  • ...2 more annotations...
  • increase in the consumption of foods containing fiber to reduce obesity, cardiovascular disease, type 2 diabetes, and some cancers.
  • One of the products of fermentation, butyrate, is able to regulate gene transcription through its actions as a histone deacetylase inhibitor, which affects cell proliferation, differentiation, and apoptosis of colon cells
