Rye products in the diabe8c diet. Postprandial glucose and hormonal responses in non- insulin- dependent diabe8c pa8ents as compared to starch availability in vitro and experiments in rats. Diabetes Res Clin Pract. 1987 Mar- Apr;3(2):85-96. Hagander B, Björck I, Asp NG, Efendić S, Holm J, Nilsson- Ehle P, Lundquist I, Scherstén B. Rye flakes, rye bread and white wheat bread were given as suspensions to rats and in standardized breakfast meals to non- insulin- dependent diabe^cs. In both cases the postprandial glucose response was lower a_er rye bread than a_er wheat bread.

NNR 2012 dra_ conclusion on dietary fiber and Risk for Type 2 Diabetes Mellitus..several larger cohort studies show convincing, protec^ve associa^ons between intake of wholegrain products and type- 2 diabetes.. 2. Fibrer och hjärt- kärl sjukdom Dietary fiber decreases fas8ng blood glucose levels and plasma LDL concentra8on in noninsulin dependent diabetes mellitus pa8ents. Hagander B, Asp NG, Efendić S, Nilsson- Ehle P, Scherstén B. Conclusion: The high- fiber diet induced lower fas8ng blood glucose levels and decreased the ra8o of low- density lipoproteins to high- density lipoproteins. 4

Effect of dietary fibre on blood glucose, plasma immunoreac8ve insulin, C- pep8de and GIP responses in non insulin dependent (type 2) diabe8cs and controls. Hagander B, Scherstén B, Asp NG, Sartor G, Agardh CD, Schrezenmeir J, Kasper H, Ahrén B, Lundquist I. Acta Med Scand. 1984;215(3):205-13.
